For the following exercises, find all solutions exactly on the interval 0≤θ<2π. 1. 2 sin θ =3–√

2. 2 cos θ =−2–√

3. tan x= 1

4. 4 sin 2x −2 =0

Find the solution of this system of equation -7x+y=-20 9x-3y=36

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.

Describe how to determine the average rate of change between x = 4 and x = 6 for the function f(x) = 2x^3 + 4. include the average rate of change in your answer.
