What is the point-slope form of the equation for the line with a slope of  6/19(6 on the top and 19 on the bottom)  that passes through the point  (−1,7//5= 7 on the top and 5 on the bottom)a. y+7/5=6/19(x−1)b. y−7/5=6/19(x+1)c. y−1=6/19(x+7/5)d. y+1=6/19(x−7/5)

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?
