Answer:
x = 3π/4, 5π/4
Step-by-step explanation:
cos(x+2π) = -√2/2, [0,2π]
cos(x)cos(2π)-sin(x)sin(2π) = -√2/2
cos(x) = -√2/2
x = 3π/4, 5π/4
Remember that the cosine function is periodic, so cos(θ+2π)=cos(θ).

Answer:
7/2 feet
Step-by-step explanation:
Volume of Right Rectangular Prism: V = w * h * l
You are given the volume, and the base (which would include l and w)- and are told to find h.
70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)
70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)
7/2 feet = h
The height will be 7/2
Answer:
The set of all positive integers equal to or greater than 1
Step-by-step explanation:
n can take on the integer values 1 ... ∞
The formula for the nth term is a(n) = a(1) + 2(n - 1)
First term: n = 1. Then a(1) = 3 + 2(0) = 3 (as expected).
5th term: n = 5. Then a(5) = 3 + 2(5 - 1) = 3 + 8 = 11
...
and so on.
