The missing term in the following polynomial has a degree of 5 and a coefficient of 16. + 13x6 - 11x3-9x2 +5x-2
Which statement best describes the polynomial?
It is not in standard form because the degree of the first term is not greater than six.
It is not in standard form because the degree of the first term should be equal to zero.
It is in standard form because the exponents are in order from highest to lowest.
It is in standard form because the coefficients are in order from highest to lowest.

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?
