Answer:he would arrive 0.2 miles faster.

Step-by-step explanation:

Distance = speed × time

Time = distance/speed

William cycles at a sped of 15 miles per hour. He cycles 12 miles from home to school. This means that the time it takes William to get to school from home would be

12/15 = 0.8 hours

If he increases his cycling speed by 5 miles per hour, his new speed becomes

15 + 5 = 20 miles per hour

Therefore, the new time it takes William to get to school from home would be

12/20 = 0.6 hours

The difference in both times is

0.8 - 0.6 = 0.2 hours

Therefore, he would arrive 0.2 miles faster.

Answer:

The correct option would be 'B. 4034'.

Step-by-step explanation:

If a population grows continuously

Then the final population is

[tex]P=P_{0}e^{rt}[/tex]

Where,

[tex]P_{0}[/tex] = Initial population

t = Number of period

r = rate of increasing per period

We have

[tex]P_{0}[/tex] = 10

r = 200%= 2  [tex](\because 1\%=\frac{1}{100})[/tex]

t = 3 years

Hence, the population of rabbits, after 3 years is,

[tex]P=10e^{2\times 3}[/tex]

[tex]P=10e^6[/tex]

[tex]P\approx 4034[/tex]

Therefore, option B is correct.

The number of rabbits after 3 years is B. 4034.

To calculate the number of rabbits after 3 years, we need to apply the continuous growth formula:

New Value = Initial Value x (1 + Growth Rate)^Time

Given that the initial value is 10 and the growth rate is 200%, we can plug in the values to find

Thus, P = 10e6

[tex]x^2-17x+72=(x-9)(x-8)[/tex]

Answer:

b = 9

a = 6

c= 8

Therefore, a,b,c = 6,9,8

Question:

The expression $x^2 - 15x - 54$ can be written as $(x-a)(x-b),$ and the expression $x^2 - 17x + 72$ written as $(x - b)(x - c)$, where $a$, $b$, and $c$ are integers. What is the value of $a b c$?

Step-by-step explanation:

To determine the values of a,b and c.

We need factorize the two equations.

i) x^2 -15x +54

x^2 -6x -9x +54

x(x-6) -9(x-6)

=(x-6)(x-9)

ii) x^2 -17x +72

x^2 -9x -8x +72

x(x-9) -8(x-9)

=(x-9)(x-8)

From the question:

Comparing

(x-a)(x-b) to (x-6)(x-9)

And

(x-b)(x-c) to (x-9)(x-8)

We can see that b is common in the two cases and also 9 is common in the two factorised equations.

So,

b = 9

a = 6

c= 8

Therefore, a,b,c = 6,9,8

Answer:

B) 6 units

Step-by-step explanation:

The formula of the volume of the Pyramid is 1/3×area of the base×height

1/3×70×height=140

Dividing both sides by 70

1/3×height=2

Multiplying both sides by 3

Height = 6

Final answer:

The height of a right square pyramid with a rectangular base area of 70 square units and a volume of 140 cubic units is 6 units, by using the volume formula of the pyramid.

Explanation:

The question asks us to find the height of a right square pyramid with a given base area and volume. To find the height, we need to use the formula for the volume of a pyramid, which is given by the formula: Volume = (Base Area * Height) / 3. We are given the base area as 70 square units and the volume as 140 cubic units.

Using the formula to solve for the height we get:
Height = (Volume * 3) / Base Area = (140 * 3) / 70 = 6 units. Therefore, the height of the pyramid is 6 units.

Answer:

(x + 1)² + (y − 3)² = 41

Step-by-step explanation:

The center of the circle is the midpoint of the diameter.

(h, k) = ((x₂ + x₁)/2, (y₂ + y₁)/2)

(h, k) = ((3 + -5)/2, (-2 + 8)/2)

(h, k) = (-1, 3)

The radius is half the length of the diameter.

r = ½ √((x₂ − x₁)² + (y₂ − y₁)²)

r = ½ √((3 − -5)² + (-2 − 8)²)

r = ½ √(8² + 10²)

r = √41

Therefore, the equation of the circle is:

(x − h)² + (y − k)² = r²

(x + 1)² + (y − 3)² = 41

The standard form of equation of the circle is (x + 1) + (y - 3) = (6.40)².

The length of the line segment bridging two points on a plane is known as the distance between the points.

The formula to find the distance between the two points is usually given by d=√{(x₂-x₁)² + (y₂-y₁)²}

Given is that the endpoints of a diameter of a circle are (3, -2) and (-5, 8).

The center: (3-5/2, -2+8/2) = (-1, 3)

The diameter d = √{(x₂-x₁)² + (y₂-y₁)²}

d = √{(-5-3)² + (8 + 2)²}

d = √{64 + 100}

d = √164

d = 12.81

The radius r = 6.40

The standard form of equation of the circle is,

(x + 1) + (y - 3) = (6.40)²

Therefore, the standard form of equation of the circle is,

(x + 1) + (y - 3) = (6.40)²

The value of the constants b and c in the given polynomial, p(x) = x² + bx + c are b = 2, and c = -24.

Given a polynomial:

p(x) = x² + bx + c

It is also given that:

[tex]\lim_{x \to 4} \frac{p(x)}{x-4} =10[/tex]

Since the denominator is x - 4 when the limit sets to 4, the denominator will have 0 there.

But, this can't be possible.

So, the expression inside the limit is given below:

The constants b and c in the polynomial satisfy the equation 4b + c = 24. There are infinitely many pairs of (b, c) that can satisfy this equation, therefore they are not unique.

In this question, we are dealing with limits and polynomials. We are given that p(x) = x2 + bx + c and lim x→4 [p(x)/(x-4)] = 10.

Substituting p(x) into the equation, we get lim x→4 [(x2 + bx + c) / (x - 4)] = 10.

Using the rule lim x→a [f(x)] = f(a), we find that 42 + 4b + c = 40. This simplifies to 16 + 4b + c = 40, and further to 4b + c = 24.

So, the constants b and c must satisfy this equation. Therefore, they are not unique as there are infinitely many pairs of (b, c) that can satisfy this equation. For example, if b = 5, then c = 4. If b = 6, then c = 0. And so on.

Answer:

 42 mph

Step-by-step explanation:

If you start with the assumption that the answer is an integer, you can solve a problem like this by looking at the factors of 294.

  294 = 2·3·7² = 6·49 = 7·42

At 42 mph, the 294-mile trip took ...

   time = distance/speed = 294 mi/(42 mi/h) = 7 h

At a speed 7 mph faster, the 294-mile trip took ...

   (294 mi)/(49 mi/h) = 6 h . . . . . 1 hour less

The average speed of Imogene's car for the 294-mile trip was 42 miles per hour.

_____

Alternative solution

If you let s represent Imogene's speed, you can use the above time and distance relationship to write an equation relating the trip times:

  294/s = 294/(s+7) +1

Multiplying by s(s+7), we get ...

  294(s+7) = 294s +s(s+7)

  2058 = s^2 +7s . . . . . . . . . . . subtract 294s

We can complete the square by adding (7/2)^2 = 12.25 to both sides

  2070.25 = s^2 +7s +12.25 = (s +3.5)^2

  ±45.5 = s +3.5 . . . . . take the square root; next subtract 3.5

  -3.5 +45.5 = s = 42 . . . . use the positive solution

Imogene's average speed was 42 mph.

Imogene's average speed was 294 mph. We solve this by using the relationship between distance, speed, and time, and applying it to the specific constraints of the problem. By setting s = speed, we use two equations representing each scenario and solve for s.

Let's assign 's' to Imogene's average speed for the trip. The time taken at this speed is the distance traveled (294 mi) divided by 's' (speed = distance/time), making the time = 294/s. If the car was faster by 7 mph, the speed would be s+7 mph, and the time taken would then be 294/(s+7). The problem states that the second scenario would take 1 hour less, so 294/s = 294/(s+7) + 1.

Cross-multiplication and simplification of this equation result in (294s + 2058) = 294(s +7) or 294s + 2058 = 294s + 2058, which simplifies to 2058 = 7s, or s = 294 mph. Therefore, Imogene's average speed was 294 mph.

Answer:

Pan is closest to Paris when she gets to Florence when she is 35 miles away

Step-by-step explanation:

With Paris at (0,0), Rome is 40miles west which is on the negative x axis.

Florence is 35 miles closer (east to Paris) so we have -45 + 35 = -10

and 55 mikes north of Rome which is on the positive y-axis. So Florence is at point (-10,55)

The distance between the two points Florence and Paris is √(x2 - x1)^2 + (y2 - y1)^2

x1 = 0, y1 = 0

x2 = -10, y2 = 55

So we have

√(-10-0)^2 + (55-0)^2

= √(-10)^2 + (55)^2

= √ 100 + 3025

= √3125

= 55.9 mikes from Paris

Pam is closest to Paris when she gets to Florence when she is 35 miles away

Pam gets closest to Paris when she is 5 miles away, which occurs when she travels directly east from Rome before heading north to Florence.

Pam is taking a train from Rome to Florence, and we need to find out how close she gets to Paris along the way. Rome is 40 miles due west of Paris, and Florence is 35 miles east and 55 miles north of Rome. While traveling from Rome to Florence, Pam would initially get closer to Paris as she travels east, but as she moves north, the closest point to Paris would be directly east from Rome before moving north.

Answer: Rita's paddling speed in still water is 2.5 miles pet hour and the speed of the river's current is 0.5 miles per hour.

Step-by-step explanation:

Let x represent Rita's paddling speed in still water.

Let y represent the speed of the river's current.

On a canoe trip, Rita paddled upstream (against the current) at an average speed of 2 miles per hour relative to the riverbank. This means that

x - y = 2 - - - - - - - - - - - - -1

On the return trip downstream (with the current) . Her average speed was 3 miles per hour. This means that

x + y = 3 - - - - - - - - - - - - -2

Adding equation 1 and equation 2, it becomes

2x = 5

x = 5/2 = 2.5 miles per hour.

Substituting x = 2.5 into equation 1, it becomes

2.5 - y = 2

y = 2.5 - 2 = 0.5 miles per hour

Question has missing the images for both type of tents hence the lengths were also missing which is attached in the picture.

Answer:

Tunnel Tent requires less nylon as its area (214.80ft²) is less than the area of Pup tent (247.40ft²)

Step-by-step explanation:

Pup Tent:

Area for Pup Tent: (Perimeter)(Height) + 2 (Area of front triangular side)

Perimeter=sum of all sides = 8+8+8=24

Height = 8

Area of Triangle = (1/2) length * height

length=8

height can be calculated by Pythagorean Theorem:

hyp²=base²+perp²

height = perp=4√3

So,

Area of Triangle = (1/2) length * height

=27.7

Hence,

Area for Pup Tent: (Perimeter)(Height) + 2 (Area of front triangular side)

=(24)(8)+(2)(27.7)

=247.40m²

Tunnel Tent:

Area of tunnel tent = πrh + πr² + 2rh

π=constant=3.14

r=radius=4

h=height=8

Area of tunnel tent = πrh + πr² + 2rh

=(3.14)(4)(8)+(3.14)(4)²+2(4)(8)

To find the number of different committees, we can use combinations. For part a, subtract the committees with the 2 men from the total number. For part b, use the same method with the women. For part c, subtract the committees with both the man and woman from the total number.

To find the number of different committees that are possible, we can use combinations. In this case, we want to choose 3 men from a group of 6 and 3 women from a group of 8. The number of combinations can be calculated using the formula:

C(n, r) = n! / (r! * (n - r)!)

a. If 2 of the men refuse to serve together, we need to subtract the number of committees with these 2 men from the total number of committees. The number of committees with the 2 men can be calculated by choosing 1 man from the remaining 4, and then choosing 2 men from the remaining 3. So the number of committees without the 2 men is C(6, 3) * C(8, 3), and the number of committees with the 2 men is C(4, 1) * C(3, 2). The total number of committees is the difference between these two values.

b. If 2 of the women refuse to serve together, we use the same method as in part a, but with the women instead of the men.

c. If 1 man and 1 woman refuse to serve together, we can subtract the number of committees with both of them from the total number of committees. The number of committees with both of them can be calculated by choosing 2 women from the remaining 6 and choosing 2 men from the remaining 5. The total number of committees is the difference between C(6, 3) * C(8, 3) and C(6, 2) * C(5, 2).

A) Component 2:

B) Component 4:

Bias in research on prisoner-guard dynamics can result from the involvement of researchers and the phrasing of questions. To ensure unbiased results, neutral interactions and carefully worded questions are vital.

Biased Research Components in Prisoner-Guard Dynamics

In research, it is crucial to mitigate factors that can lead to bias. Two such components in the study of prisoner-guard dynamics are researcher involvement and the phrasing of measurements and questions. If the researcher has direct contact with participants, they can unknowingly influence responses based on their body language, tone, or preconceived notions.

To produce unbiased results, researchers should maintain a neutral demeanor and minimize unnecessary interaction. The exact nature of measurements and questions can also introduce bias. Leading or emotional language in survey questions can skew results towards a specific answer. To avoid this, questions must be neutrally worded and designed to reflect the respondent's true perspective without influence.

Which definition for a ligament did you think was better? Explain. 1- A ligament is made up of tissue that forms a band. 2- A ligament is a band of tough tissue connecting bones or holding organs in place.

A ligament is a band of tough tissue connecting bones or holding organs in place is the better definition.

Option B

Ligament is a type of connective tissue which develops from the mesoderm. Its actually a tough band containing mostly collagen tissue. Ligament joins two bones which forms a joint.

Ligament is formed of collagen fibres which run parallel to each other and this forms a band. It's very tough and this is why, it can hold bones together.

Ligaments that hold organs are actually pseudo ligaments which are actually folds of peritonium that holds the organs in place.

A biconditional form of the statement about a ligament could be: 'An anatomical structure is a ligament if and only if it is a band of tough tissue connecting bones or holding organs in place.' It defines what a ligament is and the conditions under which we can define a structure as a ligament.

The statement, a 'ligament is a band of tough tissue connecting bones or holding organs in place,' can be written in biconditional form as: 'An anatomical structure is a ligament if and only if it is a band of tough tissue connecting bones or holding organs in place.'

This biconditional statement provides a precise definition and condition as to when we can consider a structure as a ligament. Conversely, it also states that if a structure carries out the functions mentioned, it must be a ligament.

From Exercise we have that  is boat  $250,000.

The straight line depreciation for a boat  would be calculated as follows:

Cost  boat is $250,000.  

For  $95,000 Deep Blue plans to sell it after 9 years.

We use the formula and we calculate :

(250000-95000)/9=155000/9=17222.22

Therefore, we use the  linear depreciation and we get is 17222.22 .

To calculate the annual depreciation expense for Deep Blue's boat using the straight-line method, subtract the salvage value from the purchase price and divide by the number of years of useful life, resulting in an annual depreciation expense of $17,222.22.

To determine the annual depreciation, subtract the salvage value from the purchase price and divide by the useful life of the asset in years:

Subtract the salvage value from the purchase price: $250,000 - $95,000 = $155,000.

Divide the result by the number of years of useful life: $155,000 / 9 years = $17,222.22.

Therefore, Deep Blue would record an annual depreciation expense of $17,222.22.

The volume of an oblique pyramid with a square base of edge length 2 cm and a vertical height of 3.75 cm is 5 cm³.

Explanation:

To calculate the volume of an oblique pyramid with a square base, you can use the formula for the volume of a regular pyramid since the oblique nature of the pyramid does not affect the calculation of the volume. The volume formula is Volume = (1/3) times base area times height.

Here, the base edge length is 2 centimeters, so the area of the square base (base area) is Area = side times side = 2 cm times 2 cm = 4 cm². The vertical height of the pyramid is given as 3.75 centimeters. Now we can plug these values into the volume formula:

Volume = (1/3) times base area times height
Volume = (1/3) times 4 cm² times 3.75 cm
Volume = (1/3) times 15 cm³
Volume = 5 cm³

Therefore, the volume of the oblique pyramid is 5 cubic centimeters (cm³).

The function is given by [tex]g(x) = 3x^{2} - 12x - 3[/tex].

Differentiating the function, we get [tex]\frac{d g(x)}{dx} = 6x - 12[/tex].

Now, at x = 2, 6x - 12 will be 0.

Hence, at x = 2, either the function will have maximum or minimum value.

g(2) = 12 - 24 -3 = -15.

g(1) = 3 -12 -3 = -12.

g(0) = -3.

Hence, the given function passes through (2, -15), (1, -12) and (0, -3).

Answer:

  8/3

Step-by-step explanation:

The range of possible lengths for the third side is 16±9, or 7 to 25. For lengths of 7 and 25, the area of the triangle will be zero, so the ratio of altitudes will be infinite (actually, undefined, as division by 0 is involved).

For positive triangle area and integer side lengths, the range of side lengths can be from 8 to 24. For any given triangle, the ratio of maximum altitude to minimum altitude will be the same as the ratio of the maximum side length to the minimum side length.

For the triangles under consideration, the shortest side length we can have is 8. For that 8-9-16 triangle, the ratio of the maximum to minimum side lengths is 16/8 = 2.

The longest side length we can have is 24. For that 9-16-24 triangle, the ratio of maximum to minimum side lengths is 24/9 = 8/3 = 2 2/3. This is more than 2, so 8/3 is the largest possible ratio of any two altitudes.

  A = (1/2)bh

Then the altitude for a given base (b) is ...

  h = 2A/b

That is, the altitude is inversely proportional to the base length for a triangle of a given area. Once you choose the three sides of the triangle, the area is fixed, so the ratio of altitudes is the inverse of the ratio of base lengths. The ratio of maximum altitude to minimum altitude is the ratio of the inverse of the minimum base length to the inverse of the maximum base length, which is to say it is the same as the ratio of maximum to minimum base lengths.

Answer:

8/3

Step-by-step explanation:

Sean reads 60 minutes on wednesday

Solution:

Given that,

Let "x" be the number of minutes read on monday

Let "y" be the number of minutes read on tuesday

Let "z" be the number of minutes read on wednesday

He reads 3 times as many minutes on Tuesday as he does on Monday

Number of minutes read on tuesday = 3 times the number of minutes read on monday

y = 3x --------- eqn 1

He reads 4 times as many minutes on Wednesday as he does on Monday

Number of minutes read on wednesday = 4 times the number of minutes read on monday

z = 4x ------- eqn 2

Sean reads 45 minutes on Tuesday

y = 45

Substitute y = 45 in eqn 1

45 = 3x

x = 15

Substitute x = 15 in eqn 2

z = 4(15)

z = 60

Thus he reads 60 minutes on wednesday

Final answer:

Sean reads for 60 minutes on Wednesday, calculated by knowing he reads four times as many minutes on Wednesday as on Monday, and he reads 45 minutes on Tuesday which is three times his Monday reading time.

Explanation:

Since Sean reads 3 times as many minutes on Tuesday as he does on Monday, and he reads 45 minutes on Tuesday, we can determine that he reads 45 minutes ÷ 3 = 15 minutes on Monday. Sean then reads 4 times as many minutes on Wednesday as he does on Monday. So, he must read 15 minutes × 4 = 60 minutes on Wednesday.

Answer:

The answer to your question is 4x - 5

Step-by-step explanation:

                [tex](8x -10)\frac{1}{2}[/tex]

Distributive property, this property allows us to multiply two terms separately. That means that in this problem [tex]\frac{1}{2}[/tex]  will multiply the first term, and after that the second term. One half multiply 8x and also - 10.

                 [tex]\frac{8x}{2} - \frac{10}{2}[/tex]

Simplify and result

                [tex]4x - 5[/tex]

Using the distributive property on [tex](8x - 10) \times \frac{1}{2}[/tex], we get  [tex]4x-5[/tex]

Given: [tex](8x - 10) \times \frac{1}{2}[/tex]

To find: simplify using distributive property

Distributive property can be depicted by [tex]x(a+b) = xa + xb[/tex]

We can use this property and solve as follows:

[tex](8x - 10) \times \frac{1}{2} = [\frac{1}{2} \times 8x] - [10 \times \frac{1}{2}] = 4x -5[/tex]

We get the expression without parentheses [tex]4x-5[/tex]

Answer:

Therefore the Distance across the Pond is

[tex]x=391\ ft[/tex]

Step-by-step explanation:

Given:

Triangle are Similar

AB = 90 ft

AC = 170 ft

BD = 207 ft

DE = x

To Find:

x = ?

Solution:

In Δ ABC and Δ DBE

∠A ≅ ∠D …………..{ measure of each angle is 90° given }  

∠ABC ≅ ∠DBE ……….....{Vertical Angle Theorem}  

Δ ABC ~ Δ DBE ….{Angle-Angle Similarity test}  

If two triangles are similar then their sides are in proportion.  

[tex]\dfrac{AB}{DB} =\dfrac{AC}{DE} \textrm{corresponding sides of similar triangles are in proportion}\\[/tex]  

Substituting the values we get

[tex]\dfrac{90}{207} =\dfrac{170}{x}\\\\x=23\times 17=391\ ft[/tex]

Therefore the Distance across the Pond is

[tex]x=391\ ft[/tex]

The calculated distance across the pond is 391 feet

How to determine the distance across the pond?

From the question, we have the following parameters that can be used in our computation:

The figure

Also, we have that

The figures are similar triangles

Using the proportional equation of similar triangles, we have

x/207 = 170/90

This gives

x = 207 * 170/90

Evaluate

x = 391

Hence, the distance across the pond is 391 feet

Answer:

Part 1:- option first is correct

[tex]-\frac{1}{2}ab^{12}[/tex]

Part 1:- option third is correct

[tex]\frac{w^{10}}{3y^{4}}[/tex]

Step-by-step explanation:

Given:

The given ration expressions are.

1. [tex]\frac{-2a^{2}b^{4}}{4ab^{-8}}[/tex]

2. [tex]\frac{-5w^{4}y^{-2}}{-15w^{-6}y^{2}}[/tex]

We need to simplify the given expressions.

Solution:

Part 1:-

Given expression is

[tex]=\frac{-2a^{2}b^{4}}{4ab^{-8}}[/tex]

Using law of exponents [tex]\frac{x^{m} }{x^{n} } = x^{(m-n)}[/tex]

[tex]=-\frac{a^{2-1}b^{4-(-8)}}{2}[/tex]

[tex]=-\frac{a^{1}b^{4+8}}{2}[/tex]

[tex]=-\frac{ab^{12}}{2}[/tex]

[tex]=-\frac{1}{2}ab^{12}[/tex]

Therefore, option first [tex]-\frac{1}{2}ab^{12}[/tex] is correct.

Part 2:-

Given expression is.

[tex]=\frac{-5w^{4}y^{-2}}{-15w^{-6}y^{2}}[/tex]

Using law of exponents [tex]\frac{x^{m} }{x^{n} } = x^{(m-n)}[/tex]

[tex]=\frac{w^{4-(-6)}y^{-2-2}}{3}[/tex]

[tex]=\frac{w^{4+6}y^{-4}}{3}[/tex]

[tex]=\frac{w^{10}y^{-4}}{3}[/tex]

[tex]=\frac{w^{10}}{3y^{4}}[/tex]

Therefore, third option [tex]\frac{w^{10}}{3y^{4}}[/tex] is correct.

Answer: 64 ft

Step-by-step explanation:

We are given the following equation that models the baseball's parabolic path:

[tex]s=16t^{2}+V_{o}t[/tex] (1)

Where:

[tex]s[/tex] is the ball maximum height

[tex]t[/tex] is the time

[tex]V_{o}=64 ft/s[/tex] is the initial height

With this information the equation is rewritten as:

[tex]s=16t^{2}+(64)t[/tex] (2)

Now, we have to find [tex]t[/tex], and this will be posible with the following formula:

[tex]V=V_{o}-gt[/tex] (3)

Where:

[tex]V=0 ft/s[/tex] is the final velocity of the ball at the point where its height is the maximum

[tex]g=32 ft/s^{2}[/tex] is the acceleration due gravity

Isolating [tex]t[/tex]:

[tex]t=\frac{V_{o}}{g}[/tex] (4)

[tex]t=\frac{64 ft/s}{32 ft/s^{2}}[/tex] (5)

[tex]t=2 s[/tex] (6)

Substituting (6) in (2):

[tex]s=16 ft/s^{2}(2 s)^{2}+(64 ft/s)(2 s)[/tex] (7)

Finally:

[tex]s=64 ft[/tex]
