If we graphed one period of h(t) = -4 + 7cos(25t) after how many seconds is the distance of the rider -4 feet?

3.6 seconds, 10.8 seconds
O O seconds, 7.2 seconds
O O seconds, 14.4 seconds
O 4 seconds, 7 seconds

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Ibelieve that c. recording would work best.

X= -5because this is a single step equation so you would just have to divide -16 both sides for x to equal your solution
