A. The height of a jump rope being used over time

Step-by-step explanation:

We have, the height is related periodically to the time.

That is, as the time increases the height increases and decreases in a periodic manner.

So, from the options, we see that,

B. The height of an elevator over time.

If we assume any line parallel to x-axis as the ground, then the elevator's height also have negative values.

Thus, this option is discarded.

C. The height of a commuter airplane over time.

The commuter plane once in the air, flies at a constant speed.

That is, the height graph will be parallel to the x-axis in this case.

So, this option is discarded.

D. The height of a hummingbird at a feeder.

The height of a humming bird varies randomly with respect to time and cannot be represented by a periodic function.

So, this option is also discarded.

But, the movement of jump rope is periodic and can be represented by a periodic function as shown.

Hence, option A is correct.

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.
