Evaluate the floor functions for the given value. Are the two values the same? f(x) = 2x]
g(x) = 12x1
X = 1.2
O no; f(1.2) = 2, g(1.2) = 3
O yes; f(1.2) = 2.4 = g(1.2)
no; f(1.2) = 3, g(1.2) = 2
O yes; f(1.2) = 2 = g(1.2)

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?
