C. A straight path from one point to another.
This will go -7/2,-2.1, square root of 9, 3.5,last will be square root of 5
We are given the function
F(x) = 9 sinx + cot x
We need to take the first derivative of the given function so,
F' (x) = 9 cos x - csc² x
Next, we equate the first derivative of the function to 0 and solve for the values of x
0 = 9 cos x - csc² x
Solving for x
x = 2.04
Picking out an arbitrary value between 2.04 and π, say 3 and substituting in F(x)
F(3) = 9 sin 3 + cot 3 = 19.55
Therefore, the interval where the function is increasing is from 2.04 to π
Consequently, the interval where the function is decreasing is from -π to 2.04<span />
Answer:
180°
Step-by-step explanation:
Supplementary angles are angles whose sum is 180°. If L and M are supplementary, the sum of their measures is 180°.
