Answer:
14.9 degrees
Step-by-step explanation:
For this problem you can use Tan∅=o/a and solve for the angle:
15.7 / 59 = 0.2661
Then use inverse tangent of 0.2661 to get 14.9.
Answer:
Option B.
Step-by-step explanation:
Option A.
f(x) =
Derivative of the given function,
f'(x) =
=
=
Since derivative of the function is negative, the given function is decreasing.
Option B. f(x) =
f'(x) =
=
=
Since derivative is positive, given function is increasing.
Option C. f(x) =
f'(x) =
=
=
Since derivative is negative, given function is decreasing.
Option D. f(x) =
f'(x) =
=
Since derivative is negative, given function is decreasing.
Option (B) is the answer.
