If v(x) represents the volume of water, in cubic inches, in a tank when the height of the water is x inches, give a practical interpretation of v^-1(10). a.)the volume of the water in the tank is 10 cubic inches.
b.)the volume of the water in the tank, in cubic inches, when the height is 10 inches.
c.) the height of the water in the tank is 10 inches.
d.)the height of the water in the tank, in inches, when the volume is 10 cubic inches.
e.)the volume of the water in the tank, in cubic inches, after 10 minutes.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
