Answer is
Choice C
I used the power rule for integrals.
7.5 is 30 percent of 25 because
25 divided by 10 is 2.5 times 3 is 7.5
Answer: approximately 12.17 units
==========================================================
Work Shown:
We'll use the tangent ratio to find r
tan(angle) = opposite/adjacent
tan(49) = 14/r
r*tan(49) = 14
r = 14/tan(49)
r = 12.1700143294271
r = 12.17
The radius is approximately 12.17 units long.
8k-4k+4+7-k =
8k-4k-k+4+7 =
3k+11
Divide 71 and 5 to get a decimal since 71 does not end with 5 or 0. Do it to get 14 1/5 or 14.2
