Arider’s elevation on a ferris wheel can be modeled by the function y=-16 cos(2pix)+18 where x is the time in minutes and y is the riders elevation in meters.

what is the riders elevation at the top of the ferris wheel?

how often does the rider reach the reach the elevation?

what is the midline of the does it represent ?

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

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.
