Answer: (x^3)^2 - 3^2
Step-by-step explanation:
Answer:
1. MOM can be cut in half vertically in the middle of the O.
2. HIKED can be cut in half horizontally cutting right down the middle.
3. CHECK can also be cut in half horizontally just like No. 2.
4.
M
A
T
H
can be cut in half vertically right down the middle starting at the top of M.
5. CHECKBOOK can be cut in half horizontally cutting right down the middle.
Y = X times 2 + 3 if that's what you're asking so y = 5x
Explanation:
2+3=5 so 5x bc x isn't a number

Answer: cos(76)</h3>
=========================================================
Explanation:
The original expression is of the pattern cos cos + sin sin. This pattern matches the second identity in the hint. Specifically, we'll say the following:
cos(A - B) = cos(A)cos(B) + sin(A)sin(B)
cos(A)cos(B) + sin(A)sin(B) = cos(A - B)
cos(94)cos(18) + sin(94)sin(18) = cos(94 - 18)
cos(94)cos(18) + sin(94)sin(18) = cos(76)
----------
We can verify this by use of a calculator. Make sure your calculator is in degree mode.
- cos(94)cos(18) + sin(94)sin(18) = 0.24192
- cos(76) = 0.24192
Both expressions give the same decimal approximation, so this helps confirm the two expressions are equal. You could also use the idea that if x = y, then x-y = 0. Through this method, you'll subtract the left and right hand sides and you should get (very close to) zero.
Answer:
it's is a repeating decimal
