Answer:

[tex]\frac{9}{64}[/tex] π in²

Step-by-step explanation:

The area (A) of the circle is calculated using the formula

A = πr² ← r is the radius

here the diameter = [tex]\frac{3}{4}[/tex]

and radius is half the diameter, hence

r = [tex]\frac{3}{8}[/tex], so

A = π × ([tex]\frac{3}{8}[/tex] )² = [tex]\frac{9}{64}[/tex] π in²

Answer:

D

Step-by-step explanation:

Let the following point represent the first job:  (4, $144).  Let (6, $188) represent the second.  Then we find the equation of the line through these two points.  As we go from (4, $144) to (6, $188), x increases by 2 and y increases by $44.  Thus, the slope of this line is m = rise/run = $44/(2 hrs), or $22/hr.

Using the slope-intercept formula for a  straight line, y = mx + b, we find the equation of this line by finding the y-intercept, b:

Subbing the given info ($22/hr for m, 4 hr for x and $144 for y), we get:

$144 = ($22/hr)(4 hr) + b, or

$144 = $88 + b, which yields b = $56.

Thus, the desired equation is y = mx + b, or y = ($22/hr)x + $56.  This matches the last answer (D)

Answer with Step-by-step explanation:

The length of a rectangle is 3 meters more than the width.

If the width is b.

⇒ Length=b+3

The perimeter of the rectangle is 26 meters.

Since, Perimeter=2(Length+width)

⇒ 2(b+3+b)=26

dividing both sides by 2

⇒ b+3+b=13

⇒ 2b=13-3

⇒ 2b=10

dividing both sides by 2

⇒ b=5

⇒ Width=5 meter

and Length=5+3=8 meter

You didn't post any option, but the ration roots theorem states that all possible rational roots of a polynomial come in the form

[tex]\pm\dfrac{p}{q}[/tex]

where p divides the constant term and q divides the leading term of the polynomial. So, in your case, p divides 3 (i.e. it is 1 or 3), and q divides 5 (i.e. it is 1 or 5).

So, the possible roots are

[tex]\pm 1,\quad \pm 3,\quad \pm\dfrac{1}{5},\quad \pm\dfrac{3}{5}[/tex]

For the record, this parabola has no real roots.

The possible rational roots of the polynomial function f(x) = 5x² - 3x + 3 are;

±1/5, ±3/5, ±1, ±3

      We are given the polynomial function;

f(x) = 5x² - 3x + 3

       The rational root theorem states that for a polynomial to have any rational roots, then the roots must be of the form;

±(Factors of coefficient of constant term/factors of the coefficient of the highest power)

       Now, the coefficient of the highest power is 5 and the constant term is 3.

Factors of 5 = 1, 5

Factors of 3 = 1, 3

Thus, the possible rational roots are;

±1/5, ±3/5, ±1, ±3

The approximate probability that the person will win at least $15 is 0.255.

To solve this problem, we need to calculate the probability of winning at least $15 after playing the game 30 times. Winning at least $15 means that the player must win on at least 6 rolls because winning once pays $5, and $5 times 6 is $30, which is the minimum needed to have a net gain of $15 ($30 won - $15 lost).

First, let's calculate the probability of winning in a single roll. The player wins if they roll a 3 or a 5, which are two favorable outcomes out of six possible outcomes.

[tex]\[ P(\text{win on a single roll}) = \frac{2}{6} = \frac{1}{3} \][/tex]

The probability of losing in a single roll is the complement of the probability of winning:

[tex][ P(\text{lose on a single roll}) = 1 - P(\text{win on a single roll}) = 1 - \frac{1}{3} = \frac{2}{3} \][/tex]

Now, we need to find the probability of winning at least 6 times in 30 rolls. This can be modeled using the binomial probability formula:

[tex]\[ P(X = k) = \binom{n}{k} p^k (1-p)^{n-k} \][/tex]

where [tex]\( n \)[/tex]  is the number of trials (30 in this case), [tex]\( k \)[/tex] is the number of successes (at least 6), [tex]\( p \)[/tex] is the probability of success on a single trial [tex](\( \frac{1}{3} \)), and \( \binom{n}{k} \)[/tex]  is the binomial coefficient.

We want to calculate the probability of winning at least 6 times, which is the sum of the probabilities of winning exactly 6, 7, .. up to 30 times:

[tex]\[ P(X \geq 6) = \sum_{k=6}^{30} \binom{30}{k} \left(\frac{1}{3}\right)^k \left(\frac{2}{3}\right)^{30-k} \][/tex]

[tex]\[ P(X \geq 6) \approx 0.255 \][/tex]

Given  : An equilateral triangle with side = 8 √3.

To find : What us the length of the altitude of the equilateral triangle .

Solution : We have given equilateral triangle with side = 8 √3.

By taking the half triangle,

By the Pythagorean theorem :

(Hypotenuse)² = ( adjacent)² + (opposite)².

Plug the values Hypotenuse = 8√3 , adjacent = 4√3 , opposite = h.

The given expression is

[tex] \sqrt{48 {n}^{3} } + \sqrt{9n} - \sqrt{3n} [/tex]

We remove the perfect squares under the radical sign.

[tex]\sqrt{16 {n}^{2} \times3 n} + \sqrt{9n} - \sqrt{3n} [/tex]

We can now take square root of the perfect squares and simplify them further.

[tex] \sqrt{16 {n}^{2}} \times \sqrt{3 n} + \sqrt{9} \times \sqrt{n} - \sqrt{3n} [/tex]

This simplifies to:

Answer:

•0.5

Step-by-step explanation:

We'll assume the dilation was done at the origin point, so it was done evenly.

Since the k point went from (10,0) to (5,0), we know it was reduced... so the scale factor has to be below 1. A scale factor means the size wasn't changed and a dilation/scale factor larger than 1 means it was enlarged.

So, we take the new X-value (5) and divide it by the original X-value (10).

Scale factor = 5/10 = 1/2... so 0.5

-->  x = -2,            x = -1,                    x = 3

--> x + 2 = 0         x + 1 = 0               x - 3 = 0

--> (x + 2)       ×     (x + 1)          ×       (x - 3) = 0

This is the reverse order for the Zero Product Property

Final answer:

62.5% of those surveyed prefer hamburgers.

Explanation:

The question is asking to find the percentage of people who prefer hamburgers over hot dogs when given the ratio of 5 to 3.

To calculate this, you would add the two parts of the ratio together to get the total number of parts, which is 5 + 3 = 8.

The number of parts that represent hamburgers is 5.

To find the percentage, you would divide the hamburger part by the total number of parts and then multiply by 100.

This gives you (5/8) × 100, which equals 62.5%.

Therefore, 62.5% of those surveyed prefer hamburgers.

To determine how many plants Ms. Holmes had, divide the total amount of water she had by the amount of water she gave each plant. The expression that can be used is (2 1/2 gallons) divided by (1/4 gallon per plant). Simplifying the expression gives the answer of 10 plants.

To determine how many plants Ms. Holmes had, we can divide the total amount of water she had (2 1/2 gallons) by the amount of water she gave each plant (1/4 gallon per plant).

So, the expression that can be used is (2 ½ gallons) ÷ (1/4 gallon per plant). To divide a fraction by a fraction, we multiply the first fraction by the reciprocal of the second fraction. Therefore, the expression simplifies to (2 ½ gallons) × (4 gallons per plant).

Simplifying further, we get 10 gallons. This means that Ms. Holmes had 10 plants.

Answer:

y=-1/2x+2 start at y-intercept 2 and go down by 1 and right by 2

Step-by-step explanation:

The slope-intercept form of the equation −2x−4y=−8 is y = 0.5x + 2. Starting from the y-intercept (0,2), the graph of this line is drawn by moving a half unit up and one unit to the right from the intercept.

The given mathematical equation is −2x−4y=−8. To convert this equation into slope-intercept form (y=mx+b), we want to isolate y. Start by dividing every term by -4, which simplifies the equation to 0.5x + y = 2. In this equation, the slope (m) is 0.5, and the y-intercept (b) is 2.

To graph this line, start by plotting the y-intercept (b) at the point (0, 2) on the y-axis. The slope (m) is 0.5, which we can interpret as a rise of 0.5 units for every run of 1 unit. So, from the y-intercept, move up half a unit and right one unit to plot your second point. Drawing a straight line through these points will give you the graph of your equation.

Points to remember

If the angles of a right angled triangle with angles are 30°, 60, and 90 the their sides are in the ratio 1 : √3 : 2

To find the unknown side lengths

From the given figure we can see a right angled triangle

Angles are 30°, 60° and 90°

sides are in the ratio 1 : √3 : 2

Answer:

the first function, y = (x + 1)^2, does pass through the points (1, 4), (2, 9), and (3, 16).

Step-by-step explanation:

Note that 4, 9 and 16 are squares of 2, 3 and 4.  So it's likely that the parent function is of the form f(x) = x^2.  Note that f(1) = 1, f(2) = 4, f(3) = 9 and f(4) = 16.

Let's now determine whether these three points satisfy the first given equation, y = (x + 1)^2:  Does 4 = (1 + 1)^2?  Does 4 = 2^2?  YES.

Does 9 = (2 + 1)^2?  Does 9 = 3^2?  YES

Does 16 = (3 + 1)^2?  YES

So the first function, y = (x + 1)^2, does pass through the points (1, 4), (2, 9), and (3, 16).

Final answer:

The detailed answers cover questions related to functions, sequences, equations of lines, slopes, and graphing lines.

Explanation:

Question 1:

The function that passes through the points (1, 4), (2, 9), and (3, 16) is y = (x + 1)^2.

Question 2:

The equation representing the total number of laps swum y in terms of hours x is y(x) = 10x + 1.

Question 3:

The sequence {4, 2, 0, -2, -4, -6, …} is an arithmetic sequence with a common difference of -2.

Question 5:

The slope of the line containing (3, 5) and (2, 7) is m = -2.

Question 6:

For a line passing through (-3, 2) with a slope of 4, the equation of the line is y = 4x + 14.

f(x) = 2(x+8)

replace f(x) with 12 and then solve for x:

12 = 2(x +8)

Use the distributive Property on the right side:

12 = 2x +16

Subtract 16 from each side:

-4 - 2x

Divide both sides by 2:

x = -4 / 2

x = -2

Answer:

−2

Step-by-step explanation:

f(x) = 2(x+8)

f(x) = 12

12 = 2(x+8)

Divide each side by 2

12/2 = 2/2(x+8)

6 = x+8

Subtract 8 from each side

6-8 =x+8-8

-2 = x
