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?

Acertain company's main source of income is a mobile app. the company's annual profit (in millions of dollars) as a function of the app's price (in dollars) is modeled by p(x)=-2(x-3)(x-11)p(x)=−2(x−3)(x−11 ) which app prices will result in \$0$0 annual profit? enter the lower price first.
