264 because you move the decimal 2 times to the right
Replace all x's with the value of x.
f(x) = -2x becomes f(3) = -2(3)
f(3) = -2(3)
f(3) = -6
So, -6 is the answer.
0.55^2 + cos^2 = 1
cos^2 = 1 - 0.55^2
cos^2 = 1 - 0.3025
cos^2 = 0.6975
cos = 0.8351
1/2 K - 3/5 is the answer. You’re welcome and Brainliest would be appreciated :)
