Answer:
Range = [- 2.5, 0.5] = [ - 5/2, 1/2]
Step-by-step explanation:
Smallest value of cos α = - 1,
largest value of cos α = 1.
When cos 4x = - 1, y=3/2cos4x-1 = 3/2*(-1) - 1 = - 5/2 = - 2 1/2 = - 2.5
When cos 4x = 1, y=3/2cos4x-1 = 3/2*1 - 1 = 1/2 = 0.5
Range = [- 2.5, 0.5] = [ - 5/2, 1/2]
Answer:
sorry but it is wrong the answer is 1,200
Step-by-step explanation:
The answer can't be C or D because the unit of volume is always cubed. The formula for volume of cylinder is (pi)(r^2)(h) . The pi(r^2) part is the formula for area of a circle which is what the base of the cylinder is. Fortunately the area is already given as 28.2. Plug that into the volume formula and plug in 3.1 for the height and multiply. I get 87.42 and the answer choice B seems to be the closest option

Answer:
and 
Step-by-step explanation:
We want to find roots of the function: 
. The roots are the numbers that make the function f(q) = 0. So set the expression equal to 0:
Add 125 to both sides:
Square root both sides:
+/- 
= +/- 
= +/-
So, the answers are and . (Sorry, I can't tell what the answer choices are)
Hope this helps!
