The coordinates of the vertices of △abc are a(−1, 1) , b(−2, 3) , and c(−5, 1) . the coordinates of the vertices of △a′b′c′ are a′(−1, −4) , b′(−2, −6) , and c′(−5, −4) . which statement correctly describes the relationship between △abc and △a′b′c′ ? △abc is congruent to △a′b′c′ because you can map △abc to △a′b′c′ using a translation 3 units down followed by a reflection across the x-axis, which is a sequence of rigid motions. △abc is congruent to △a′b′c′ because you can map △abc to △a′b′c′ using a translation 5 units down followed by a reflection across the x-axis, which is a sequence of rigid motions. △abc is not congruent to △a′b′c′ because there is no sequence of rigid motions that maps △abc to △a′b′c′ . △abc is congruent to △a′b′c′ because you can map △abc to △a′b′c′ using a reflection across the x-axis followed by a translation 3 units down, which is a sequence of rigid motions.

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?
