The derivative of a variable raised to exponent of n, x^n is equal to the product of n and x raised to exponent of n-1.
d(x^n) = (n)(x^n-1)
So, from the given
d(9x + 5) = (1)(9x^1-0) + 5(0)
= 9
The given value of x is irrelevant to this item because the derivative does not contain any variable x.
(85 + 60) ÷ 2 = 72.5 Close to 71%
Answer: D - 71%
Answer:
300 degrees
Step-by-step explanation:
we know that 

we have to find value of 
for that we have to multiply 5/6 to
and 360 degrees

Thus,
= 300 degrees.
