1. write the equation of a line in slope intercept form that is perpendicular to the line y = –4x and passes through the point (2, 6). 2. k is the midpoint of segment ab. if segment ak = 3x+1 and segment kb = 1/3x + 9, find the length of segment ak. 3. j is the midpoint of segment kl. the coordinates of j are (-8,7) and the coordinates of k are (3,4). find the coordinates of l. @ttking40

Tan198=asin164=? how to solve this? ?

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?
