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

good luck!

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
