Answer:

[tex]-16t^2 + 1,000>300[/tex]

[tex]t<6.61\ s[/tex]

Step-by-step explanation:

We know that the distance of the object while falling is given by the equation:

[tex]d = -16t^2 + 1,000[/tex]

To find the time interval in which the object is at a height greater than 300 ft, we must do

[tex]d> 300[/tex]

So

[tex]-16t^2 + 1,000>300[/tex]

[tex]-16t^2>-700[/tex]

[tex]16t^2<700[/tex]

[tex]t^2<\frac{700}{16}[/tex]

[tex]t<\sqrt{\frac{700}{16}}[/tex]

[tex]t<6.61\ s[/tex]

The interval is

t ∈ (0, 6.61)

And the inequality used  is: [tex]-16t^2 + 1,000>300[/tex]

aka D

Step-by-step explanation:

I did the quiz

Answer:

See below

Step-by-step explanation:

Step 1.

P = $400

r = 0.04

t = 10 years

n = 12  ( as there are 12 months in a year).

Step 2.

A(10) = 400(1 + 0.04/12)^12^10

= 400 * 1.00333333^120

= $596.33 to the nearest hundredth (answer).

Answer and Explanation:

Given : The value of $400 invested at 4% interest compounded monthly for 10 years.    

To find : The value of each of the following for this problem ?

Solution :

The interest formula is [tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex]

Step 1 -

P is the amount invested, P=$400

r is the interest rate, r=4%=0.04

t is the time , t=10 years

n is the number of compounding periods per year, n=12

Step 2 - To find A(10),

Substitute all the values in the formula,

[tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex]

[tex]A(10)=400(1+\frac{0.04}{12})^{12\times 10}[/tex]

[tex]A(10)=400(1+0.0033)^{120}[/tex]

[tex]A(10)=400(1.0033)^{120}[/tex]

[tex]A(10)=400(1.490)[/tex]

[tex]A(10)=596.33[/tex]

Therefore, The amount after 10 year is $596.33.

Answer:

y=2x

Step-by-step explanation:

2 up, 1 over. put rise over run so that concludes the 2x.

The line starts at 0 so there is no y-intercept

y=2x The "formula" would be y=mx+b where m is the slope and b is the y-intercept. in this case, the slope is 2 and the y-intercept is 0 therefore the equation is y=2x (no zero because we can atoumtucally assume that its a zero)

Answer:

x = [tex]\frac{5}{26}[/tex]

Step-by-step explanation:

Given equation:

[tex]\frac{3}{4}x + \frac{5}{8} = 4x[/tex]

[tex]\frac{3(2)x + 5}{8} = 4x[/tex]            ∵taking GCF 8

[tex]\frac{8 (6x + 5) }{8}[/tex]  = 4x × 8

6x + 5 = 32x    ⇒   5 = 32x - 6x   ⇒  5 = 26x   ⇒  x = [tex]\frac{5}{26}[/tex]

Answer: [tex]\angle G=23\°[/tex]

Step-by-step explanation:

Remember that an inscribed angle is defined as an angle formed by two chords and whose vertex lies on the circle.

By definition, the measure of an inscribed angle is:

[tex]Inscribed\ Angle=\frac{Intercepted\ Arc}{2}[/tex]

You know that:

[tex]Intercepted\ Arc=AD = (6x -80)\\\\Inscribed\ Angle=\angle G=(x + 2)[/tex]

Then, you need to substitute values and solve for "x":

[tex](x+2)=\frac{(6x -80)}{2}\\\\2(x+2)=6x-80\\\\2x+4=6x-80\\\\4+80=6x-2x\\\\84=4x\\\\x=\frac{84}{4}\\\\x=21[/tex]

Substituting the value of "x" into [tex]\angle G=(x + 2)\°[/tex] you get:

 [tex]\angle G=(21 + 2)\°=23\°[/tex]

Answer:

The measure of <G =  23°

Step-by-step explanation:

From the figure we can write,

The measure of <G is half the  the measure of arc AD

To find the value of x

We have  AD = (6x - 80)° and <G = (x + 2)°

6x - 80 = 2(x + 2)

6x - 80 = 2x + 4

6x - 2x = 4 + 80

4x = 84

x = 84/4 = 21

To find the measure of <g

m<G = x + 2

 = 21 + 2 = 23°

Therefore the measure of <G =  23°

Answer:

x = 21

Step-by-step explanation:

Answer:

x = -2 or x=6

Step-by-step explanation:

Given

f(x) = 3Ix-2I + 6

As we know that

f(x) = 18

Putting both equal

3Ix-2I+6 = 18

Two cases are possible

Case 1: Negative Modulus

3* -(x-2) + 6 = 18

3(-x+2)+6 = 18

-3x+6+6 = 18

-3x +12 = 18

-3x = 18 - 12

-3x = 6

x = 6/-3

x = -2

Case 2: Positive Modulus

3(x-2)+6 = 18

3x-6+6 = 18

3x = 18

x = 18/3

x = 6

So for x= -2 or x=6 the value of function will be 18..

Answer:

1,206

Step-by-step explanation:

Since we'll have to deal with cubic inches (with the ball volume), we should also calculate the volume of the car in cubic inches.

We are told the car is a rectangular prism measuring 10ft x 5 ft x 3 ft.

So, in inches (12 inches/foot), we have: 120 in x 60 in x 36 in = 259,200 cu inches.

The ball is a sphere with a radius of 3 inches.

Real volume of the ball: V = (4/3) π r³

V = (4/3) π 3³ = 36 π = 113.1 cu inches

But of course, balls don't fit perfectly one next to another, like cubes, so we have to take into account the loss... the question tells us to use a factor of 190%.

So, the packing volume of a ball is 190% its real volume:

PV = 190% * 113.1 = 214.9 cu inches

Now, how many times does that fit inside the car?

259,200 / 214.9 = 1,206.14

Let's round it to 1,206, which is a possible answer.

Answer:

$7.50

Step-by-step explanation:

Since the price of the picnic cooler 7.95 with 6% sales tax, we can write:

X*1.06 = 7.95

Dividing both sides by 1.06,

X= 7.50

So Anton paid $7.50 alone without tax

Answer: Cost of cooler alone = $7.47

Step-by-step explanation:

Anton's bill including tax = $7.95

6% of his bill accounts for sales tax.

Sales tax = 6/100 × 7.95 ≈ $0.48

So cost of cooler alone =  Total bill - tax

= 7.95 − 0.48

= $7.47

There is another way of doing this problem as well, but which ever one is easier for you could it.

Anton's bill including tax = $7.95, out of this 6% is sales tax. This implies 94% (100 − 6) of total bill accounts for cooler alone.

Cost of cooler alone:

=94/100 ×7.95

= 0.94 ×7.95

= $7.47

Answer:

g(x)=(x+7)^2-3

Step-by-step explanation:

Given:

f(x)= x^2

Now we have to translate f(x) 7 units to the left and 3 units down to form the function g(x).

As per the rules of translation

when any parent function, in given case f(x)=x^2, is translated to 'a' units to the left then 'a' is added to the value of x. thus making f(x+a)

Also when the parent function is translated any 'a' units down then 'a' is subtracted from the value of function. thus making f(x)-a

Translating f(x), 7 units to the left

f(x+7)= (x+7)^2

Translating f(x+7), 3 units down

f(x+7)-3 = (x+7)^2-3

Hence new function g(x)=(x+7)^2-3!

If [tex]m\widehat{BY}=40^\circ[/tex], then the central angle [tex]\angle BOY[/tex] has the same measure, and by the inscribed angle theorem we have

[tex]m\angle BAY=\dfrac12m\angle BOY=20^\circ[/tex]

It's impossible to know what the measure of angle YAC is from this information alone, but assuming AC is tangent to the circle, then angles BAY and YAC are complementary, so that [tex]m\angle YAC=70^\circ[/tex].

The line AC is the tangent of the line, and the measure of the angle YAC is 70 degrees

The measure of the arc is given as:

Arc BY = 40 degrees

The measure of angle BAY is calculated using:

BAY = 0.5 * BY

This gives

BAY = 0.5 * 40

BAY = 20

The angle at a tangent is 90 degrees.

This means that:

BAY + YAC = 90

Substitute 20 for BAY

20 + YAC = 90

Subtract 20 from both sides

YAC = 70

Hence, the measure of the angle YAC is 70 degrees

Convert into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex]f(x)-3=x^{2}+2x[/tex]

Complete the square. Remember to balance the equation by adding the same constants to each side.

Answer: p+(q÷r) this is because you divide a and r and add p to it

Should be “p+q/r”.

Using English grammar, one can group the terms using “sum of...”, “product of...”, and “quotient of x and y.” (Where ... can be “x and y”)

Subtracting in English is slightly different using “x subtracted from y” meaning “y-x”.

All of these terms can be used in tandem to create expressions like the given answer.

Hello there! The value of y is -5/4.

So, basically look at it like an ordered pair, (x, y). When we have (5, y), we have a value of x and are looking for a value of y. To do this, plug the value for x (5) into the equation and solve for y.

5x+4y-20=0

5(5)+4y-20=0

Now that you have the value for x, solve for y.

5(5)+4y-20=0 - Start by multiplying out the parenthesis.

25 + 4y - 20 = 0 - Next, combine like terms.

25 - 20 + 4y = 0

5 + 4y = 0 - Now, subtract 5 from both sides.

4y = -5 - Lastly, divide both sides by 4.

y = -5/4.

This is your final answer. I hope this helps and have a great day! :)

To find the value of y, substitute the given coordinates (5, y) into the equation 5x + 4y - 20 = 0. Simplify the equation and solve for y to get y = -1.25.

To find the value of y, we can substitute the given coordinates (5, y) into the equation.

According to the equation 5x + 4y - 20 = 0, when x is 5, we have:

5(5) + 4y - 20 = 0.

Simplifying this equation gives us:

25 + 4y - 20 = 0.

Combining like terms, we get:

4y + 5 = 0.

Next, we can isolate the y-term by subtracting 5 from both sides of the equation:

4y = -5.

Finally, we can solve for y by dividing both sides of the equation by 4:

y = -5/4, or y = -1.25.

Simplify the expression.

Answer:

452.39

Step-by-step explanation:

A=(pi)r^2

A=3.14(12)^2

A=452.39

Answer: The area of the circle is 452.16 square units.

Step-by-step explanation:

To find the area of a circle you need to use the area of a circle formula. The formula is A= π x r^2.

π= 3.14

r= 12

The r is radius which is half of the diameter. When you apply the formula you get :

A = 3.14 x 12^2

A= 3.14 x 144

A= 452.16

Answer:

The centre is at (-12, 9) and the radius = 5 units.

Step-by-step explanation:

x^2 + y^2 + 24x - 18y + 200 = 0

x^2 + 24x + y^2 - 18y = -200

Completing the square on the x and y terms:

(x + 12)^2 - 144 + (y - 9)^2 - 81 = -200

(x + 12)^2 + (y - 9)^2 = -200 + 144 + 81

(x + 12)^2 + (y - 9)^2 = 25

So the centre is at (-12, 9) and the radius = the square root of 25 = 5.

Answer:

centre = (- 12, 9), radius = 5

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given

x² + y² + 24x - 18y + 200 = 0

Collect the terms in x/ y together and subtract 200 from both sides

x² + 24x + y² - 18y = - 200

Using the method of completing the square

add ( half the coefficient of the x/ y term )² to both sides

x² + 2(12)x + 144 + y² + 2(- 9)y + 81 = - 200 + 144 + 81

(x + 12)² + (y - 9)² = 25 ← in standard form

with centre (- 12, 9) and r = [tex]\sqrt{25}[/tex] = 5

Answer:

The original number is 4 1 5 3 OR 4 5 8 3

Step-by-step explanation:

* Lets find a way to solve this problem

- The end of the 4-digit number is 3

∴ The number is # # # 3

- The number decrease by 738 if the 3 becomes the first number

∴ The new number is 3 # # #

- Make it as a subtraction problem

∵ # # # 3 - 3 # # # = 0 7 3 8

- Lets subtract

∵ 3 - # = 8

∵ 8 > 3 we must borrow 1 from the number before 3

∴ 13 - 8 = 5

∴ # # # 3 - 3 # # 5 = 0 7 3 8

- Put the 5 in the first number, we can not pot it as a first number

 bwcause when we subtract it from 3 the answer will be 2 but we

 need answer zero

∴ Lets put it before the 3

∴ # # 5 3 - 3 # # 5 = 0 7 3 8

∵ we borrowed 1 from the 5 before

∴ 4 - # = 3

∴ # = 4 - 3 = 1

∴ # # 5 3 - 3 # 1 5 = 0 7 3 8

- Now we must use the 1 in the first number we can not put it as a

 number because it is smaller than 3, we must put it in the 2nd

 missing place

∴ # 1 5 3 - 3 # 1 5 = 0 7 3 8

∵ 1 - # = 7

∵ 1 < 7 so we must borrow 1 from the number before it

∴ 11 - # = 7

∴ # = 11 - 7 = 4

∴ # 1 5 3 - 3 4 1 5 = 0 7 3 8

- We must use the 4 in the first number and we have only one

 missing place (the first place)

∴ 4 1 5 3 - 3 4 1 5 = 0 7 3 8

∴ The original number is 4 1 5 3

* You can find another answer if you put the 5 in the 2nd place in the

 first number the answer will be 4 5 8 3 try to do it
