Solve for the value(s) of constant c that will make h(x) continuous at x = −1. h(x) = { (x + c)^2 if x < -1
c + x if x >= -1 }

A. c = 0 only
B. c = 1 and c = 2
C. c = 1 only
D. c = 1 and c = -2

Please justify your answer with a step by step process.

Solve for x and select the correct answer

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?
