A communication company is planning to launch a new satellite into orbit to improve their network. The range of communication for their satellite is 4,500 miles. They know that the approximate radius of the earth is 3,960 miles. The company is trying to determine what height to put the satellite at so that it has maximum coverage of the earth. Determine at what height about the surface of the earth the satellite needs to be placed.
To the nearest mile, the satellite needs to be placed at a height of
miles above the earth.

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)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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.
