Estimate the instantaneous rate of change at the point indicated. (Round your answer to four decimal places.) y(x) = 1 x + 2 ; x
Wittaler [7]

Answer:

-1/36

Step-by-step explanation:

Estimate the instantaneous rate of change at the point indicated

To find the instantaneous rate of change we find the derivative of the given function

Instantaneous rate of change is the rate of change at the given point

f(x)=\frac{1}{x+2}

To find derivative we apply power rule

f(x)=(x+2)^{-1}

f'(x)=-1(x+2)^{-2}

f'(x)=\frac{-1}{(x+2)^2}

Now plug in 4 for x in f'(x)

f'(4)=\frac{-1}{(4+2)^2}

f'(4)=\frac{-1}{36}

Ilia_Sergeevich [38]

11 ounces

Step-by-step explanation:

Unpeeled = X

Peeled = (1 - 1/12)X = (11/12)X

X = (11/12)X + (11/12)

X - (11/12)X = 11/12

(1/12)X = 11/12

X = 11 ounces

3. Here is a list of exam scores for Mr. Kraft's calculus class:
Alja [10]

Answer

15%

Step-by-step explanation:

I think the answer is 15% because when we talk about percentile, we are actually subtracting from 100% in simpler terms. If we say a 85th percentile, it actually means 15%.
