H(t) = 1/2 at^2 As a space probe descends to the surface of Mars, its distance in meters above the surface can be modeled by the equation above. If I is the time in seconds it will take the probe to reach the surface, and it takes the probe 8 seconds to descend the final 120 meters to the surface, what is the value of the deceleration constant a?

Felipe is saving money for a class trip. he already has saved $ 2 5 0 $250 that he will put toward the trip. to save more money for the trip, felipe gets a job where each month he can add $ 3 5 0 $350 to his savings for the trip. let m m be the number of months that felipe has worked at his new job. if felipe needs to save $ 2 7 0 0 $2700 to go on the trip, which equation best models the situation?
