Answer:

Answer:

5:6 --> 10:12

Step-by-step explanation:

A good way to think of this is to provide a perspective: there are 5 boys every time there is 6 girls. So if there is 10 boys, that means there would be 12 girls (because 5 *2 = 10 and 6*2 = 12).

tl:dr: 5 *2 = 10 so 6*2 = 12

Hello there can anyone solve this plz (chart is attached):

stich3 [128]

Answer:

$h^\prime(1)=14$

Step-by-step explanation:

We have the function:

$h(x)=f[f(x)]$

And we want to find:

$h^\prime(1)$

So, we will differentiate function <em>h</em>. By the chain rule, this yields:

$h^\prime(x)=f^\prime[f(x)]\cdot f^\prime(x)$

Then it follows that:

$h^\prime(1)=f^\prime[f(1)]\cdot f^\prime(1)$

Using the table, we acquire:

$h^\prime(1)=f^\prime(3)\cdot2$

And using the table again, we acquire:

$h^\prime(1)=7\cdot 2$

Evaluate. Hence:

$h^\prime(1)=14$

408.454 cubic inches of air is surrounding the ball in the box

Step-by-step explanation:

When a sphere is inscribed in a cube and touching all of its faces, then

The diameter of the sphere = the side of the cube
The empty volume of the cube is the difference between the volume of the cube and the volume of the sphere

∵ The basketball is shaped a sphere

∵ The box is shaped a cube

∵ The ball touching every wall of the box

∴ The diameter of the ball = the side of the box

∵ The length of one side of the cube = 9.5 inches

∴ The diameter of the ball = 9.5 inches

∵ The diameter of the ball = 2 r, where r is the radius of the ball

∴ 9.5 = 2 r

- Divide both sides by 2

∴ r = 4.75 inches

∵ The volume of the air that surrounded the ball in the box =

volume of the box - volume of the ball

∵ Volume box (cube) = s³

∵ s = 9.5 inches

∴ Volume of the box = (9.5)³

∴ Volume of the box = 857.375 inches³

∵ Volume the ball (sphere) = $\frac{4}{3}$ π r³

∵ r = 4.75

∴ Volume the ball = $\frac{4}{3}$ (π)(4.75)³

∴ Volume the ball = 448.921 inches³

Substitute the values of the volumes of the box and the ball in the rule above

∴ The volume of the air = 857.375 - 448.921

∴ The volume of the air = 408.454 inches³

408.454 cubic inches of air is surrounding the ball in the box
