Tomas is finding the coordinates of point a. he knows that point a has an x-coordinate of 8. he starts to compute the value of the y-coordinate. complete tomas’s work to answer the question. which is the coordinate of point a? (8, –6) (–6, 8) (6, –8) (–8, –6)

I’m still confused on how to work the percentages

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?

Cole says the distance between points (-5,0) and (0,-5)is 5 units. is he correct? explain why or why not.
