Answer:

a = 15

Step-by-step explanation:

g(x) is the same thing as "y". Our point gives us an x and y value, so we will sub those into the equation and solve for a:

-2 = a(1/3) - 7 and

-2 = 1/3a - 7 and

5 = 1/3a so

a = 15

Answer:

33.49 cubic units

Step-by-step explanation:

$V_{sphere} = \frac{4}{3} \times \pi {r}^{3} \\ \\ V_{sphere} = \frac{4}{3} \times \pi {(2)}^{3} \\ \\ V_{sphere} = \frac{4}{3} \times \pi \times 8 \\ \\ V_{sphere} = \frac{32 \times 3.14}{3} \\ \\ V_{sphere} = \frac{100.48}{3} \\ \\ V_{sphere} = 33.4933333\\ \\ V_{sphere} \approx 33.49\: units^3$
