1. C -9
2. B 7.5
3. A -4
4. C 65
Answer:
(4500(Pi))/2 or 7068.585
Step-by-step explanation:
r = 15 cm
volume of a sphere:
(4/3)(Pi)r^3
Therefore:
(4/3)(Pi)15^3
15^3 = 3375
4/3 * 3375 = 4500
and since it is half a sphere (it is a bowl) the answer would be divided by two:
4500(Pi) divided by 2
14137.17 divided by 2
It will be 165.85365853658536. Hope this helps !!
Problem 3
This is not an exponential function. If you were to graph this out, you would see a parabola forming. Or at the very least, a parabolic-like curve forms. An exponential curve only increases or only decreases for the entire domain. However, in this case, we have an increasing portion, and then it decreases.

Problem 4
This is an exponential function. Each time x increases by 1, y is multiplied by 4. The equation that models these points is y = 4^x. Note how the function is strictly increasing and there are no decreasing portions mixed in.
It would be in the fourth quadrant because x is positive and y is negative. The quadrants are labeled in counter-clockwise order, starting in the upper-right.
