A basketball has a volume of 23047 cm
Elodia [21]

Answer:

17.65693585 = r

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

23047 = 4/3 (3.14) r^3

23047 = 4.1866666666 r^3

Divide by 4.186666 on each side

23047/4.18666666 = 4.1866666666/4.18666666 *r^3

5504.856688 = r^3

Take the cubed root on each side

(5504.856688)^1/3 = r^3^(1/3)

17.65693585 = r

What are the maximum and minimum of the function f(x) = 0.9|-(x − 5)| + 7?
r-ruslan [8.4K]

Answer:

Maximum value:

the maximum value is \infty

Minimum value:

the minimum value is 7

Step-by-step explanation:

We are given function as

f(x)=0.9|-(x-5)|+7

Firstly, we will draw graph

we can see the graph

and then we can identify maximum and minimum

Maximum value:

We know that

the largest y-value means maximum value of f(x)

We can see that curve is moving upward

so, the maximum value is \infty

Minimum value:

We know that

the smallest y-value means minimum value of f(x)

we can see that

It starts from point (5,7)

so, the minimum value is 7
