Answer:
r = 9.8475 in
Step-by-step explanation:
We assume that the ball is spherical.
The volume of a spherical ball is:
We know that:
Then
![r ^ 3 = \frac{3*4000}{4(\pi)}\\\\r = \sqrt[3]{\frac{3*4000}{4(\pi)}}\\\\r = 9.8475in](https://tex.z-dn.net/?f=r%20%5E%203%20%3D%20%5Cfrac%7B3%2A4000%7D%7B4%28%5Cpi%29%7D%5C%5C%5C%5Cr%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B3%2A4000%7D%7B4%28%5Cpi%29%7D%7D%5C%5C%5C%5Cr%20%3D%209.8475in)
Below is the graph of the cubic function
The last choice, f(x)=1/4(4ˣ⁻⁻¹)-4, is correct.
Substituting our values for x, we have:
f(2) = 1/4(4²⁻¹)-4 = 1/4(4¹) - 4 = 1/4(4) - 4= 1 - 4 = -3
f(3) = 1/4(4³⁻¹)-4 = 1/4(4²) - 4 = 1/4(16) - 4 = 4 - 4 = 0
f(4) = 1/4(4⁴⁻¹)-4 = 1/4(4³) - 4 = 1/4(64) - 4 = 16 - 4 = 12
All of the data points fit.
Slope m=2

Answer:
I don't think that there is two same results. sorry I couldn't help
Step-by-step explanation:
for I the answer should be 10 if you replaced each x by 2. f(2) = 3(2) + 4
and for II it will be f-1(4) = 3-1(4) - 4 /5 the answer will be -1.
for III it should be y = 8 or 4
