A polynominak function has a root of -6 with a multiplicity 1, a root if -2 with a multiplicity of 3, a root if 0 with a multiplicity of 2, a root if 4 with a multiplicity of 3. if the function has a posative leading coefficient and is of odd degree, which statement about the graph is true? a. the graph of the function is positive on (-6,-2)
b the graph of the function is negative on (-infinity symbol, 0)
c. the graph of the function is positive on (-2,4)
d. the graph of the function is negative on (4, infinity symbol).

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?
