Use the trig identity
2*sin(A)*cos(A) = sin(2*A)
to get
sin(A)*cos(A) = (1/2)*sin(2*A)
So to find the max of sin(A)*cos(A), we can find the max of (1/2)*sin(2*A)
It turns out that sin(x) maxes out at 1 where x can be any expression you want. In this case, x = 2*A.
So (1/2)*sin(2*A) maxes out at (1/2)*1 = 1/2 = 0.5
The greatest value of sin(A)*cos(A) is 1/2 = 0.5

Answer:
WX = 9
Step-by-step explanation:
WY is the entire line - this tells you that the length of the entire line is 11.
XY is a section of the line, and WX is the section you need to find the length for. Since it is given that XY is of length 2, we can find the length of WX by subtracting the length of XY from WY.
11 (WY) - 2 (XY) = 9.
Answer:
≈ 8.07 mg
Step-by-step explanation:
Given
f(x) = 12
Substitute x = 1 into f(x) , that is
f(2) = 12(0.82)² = 12 ×0.6724 ≈ 8.07 mg
