point q is plotted on the coordinate grid. point p is at (40, −20). point r is vertically above point q. it is at the same distance from point q as point p is from point q. which of these shows the coordinates of point r and its distance from point q?

1) point r is at (−10, −10), a distance of 30 units from point q
2) point r is at (−10, −30), a distance of 50 units from point q
3) point r is at (−10, 30), a distance of 50 units from point q
4) point r is at (−10, 10), a distance of 30 units from point q

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

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?
