S=1/2^2
The formula shown represents the distance s that a free-falling object will fall near a planet or the moon in a given time t. In the formula, a represents the acceleration due to gravity.

1) Solve the formula for a.

2) Solve the formula for t.

3) A free-falling object near the moon drops 20.5 meters in 5 seconds. What is the acceleration a for the moon?

4) Using this value for a, determine how many seconds it will take for an object to fall 42.5 meters.

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
