Answer:
57
Step-by-step explanation:
I prefer the equation in this format

substitute -4 for m and 6 for n

square the 6 then multiply by 2

solve inside the absolute value then multiply by 3


divide by 4

Answer:
-11
Step-by-step explanation:
y=-5-3(2)
-5-6=-11
Answer: D
<u>Step-by-step explanation:</u>
f(x) = 2x g(x) = x² - 1
f(g(x)) = 2(x² - 1)
= 2x² - 2
g(f(x)) = (2x)² - 1
= 4x² - 1
Around 150 rotations
I rounded the radius to feet which is 1 foot. Then you have to get the diameter which is 1x2=2. The diameter is 2 feet. Now for the circumference, we multiply 2 by 3.14(which is pi). The answer to that is 6.28, and since we are rounding it, we get 6 feet. However, we are traveling 900 feet. Divide 900 by 6 and get 150.
