Answer:

4x-4/x^2

Step-by-step explanation:

So we can first write out the equation.

It would be:

8/2x-4/x^2

First we can get a common denominator:

8/2x*x^2/x^2=8x^2/2x^3

and

4/x^2*2x/2x=8x/2x^3

Now we have

8x^2/2x^3-8x/2x^3

or

8x^2-8x/2x^3

We can divide everything by x

8x-8/2x^2

divide everything by 2

4x-4/x^2

find the areas of all the faces and add them up

area of a rectangle: bh

area of a trapezoid: \frac{1}{2} (b_1 + b_2)(h)

(5*3)+(6*3)+(5*3)+(3*12)+2(\frac{1}{2}*(6+12)*4) \\=15+18+15+36+2(\frac{1}{2}*18*4)\\=84+2(36)\\=156

the area of the trapezoid is multiplied by 2 because there's a top and bottom

What does h(3.2) represent?
marshall27 [118]

Answer:

the height of the rock 3.2 seconds after it is propelled

Step-by-step explanation:

<u><em>The complete question is</em></u>

The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot

Let

t------> the time in seconds

h----> the the height of a rock after it is propelled by a slingshot in meters

we know that

h(t)=-16t^{2} +28t+500

For x=3.2\ sec

Find the value of h(t)

h(3.2)=-16(3.2)^{2} +28(3.2)+500=425.76\ meters

therefore

h(3.2) represent the height of the rock 3.2 seconds after it is propelled

see the attached figure to better understand the problem

Mozart's Music Store rents trombones for $34 a month. Bach's Music Store rents trombones for $30 per month plus a yearly fee of
jeka94

Answer:

Step-by-step explanation:

Let M(x) be the cost of renting from Mozart's Music Store for x years, and B(x) be the cost of renting from Bach's Music Store for x years.

From the problem statement, we can come up with the following equations:

M(x) = 34(12x)

B(x) = 30(12x) + 48x

Plugging in x = 9 for each equation, we can get the answer:

M(9) = 34(12 * 9)

M(9) = 34(108)

M(9) = 3672

B(9) = 30(12 * 9) + 48(9)

B(9) = 30(108) + 432

B(9) = 3240 + 432

B(9) = 3672

From this, we can see that the value is equal for both stores.
