Find the volume of the prism.<br> H-8cm L-12cm W-6cm
babymother [125]

Answer:

Step-by-step explanation:

Let’s break this apart.

Box= 12cm x 8cm x 6cm

Cube= 2cm x 2cm x 2cm

How many cubes fit in the box?

calculate the volume of the box. To do this, multiply the length by the width by the height (L x W x H)

12 x 8 x 6 = 576cm cubed

2. Calculate the volume of the cube. Once again we multiply L x W x H

2 x 2 x 2 = 8cm cubed

3. Next we divide the volume of the box by the volume of the cube

576 / 8 = 72 cubes

Therefore, it would take 72 cubes to fill a box.

Estimate the instantaneous rate of change at the point indicated. (Round your answer to four decimal places.) y(x) = 1 x + 2 ; x
Wittaler [7]

Answer:

-1/36

Step-by-step explanation:

Estimate the instantaneous rate of change at the point indicated

To find the instantaneous rate of change we find the derivative of the given function

Instantaneous rate of change is the rate of change at the given point

f(x)=\frac{1}{x+2}

To find derivative we apply power rule

f(x)=(x+2)^{-1}

f'(x)=-1(x+2)^{-2}

f'(x)=\frac{-1}{(x+2)^2}

Now plug in 4 for x in f'(x)

f'(4)=\frac{-1}{(4+2)^2}

f'(4)=\frac{-1}{36}
