Answer:
<em>The difference quotient of f is 8. </em><em>Option C</em>
Explanation:
<u>Difference Quotient</u>
Given a function f(x), the difference quotient is defined as

The function provided in the question is

Find f(x+h) by substituting x by x+h:


Now compute:

Operating:

Simplifying:

d=8
A. Incorrect.
This choice is different from the answer.
B. Incorrect.
This choice is different from the answer.
C. Is correct
The difference quotient is 8 as explained above.
D. Incorrect.
This choice is different from the answer.
A = 1/2 h (b1+b2)
so
h = 2A / (b1+b2)
h = [2(3x^2 + 5x)] / (2x + 1 + <span>x + 4)
h = (6x^2 + 10x)/(3x +5)
h = 2x(3x + 5)/(3x +5)
h = 2x
answer: </span><span>height of a trapezoid = 2x</span>
Answer: 
Step-by-step explanation:
Given
Taylor has nickels and dimes
Number of nickels is 7 less than eight times the number of dimes
If d is the number of dimes, then number of nickels is given by

A) a=8
B) b=1/8
C) c=13/5
D) d=13/50
Answer: Disposable income = $100.
Explanation:
Since we have given that

And, average propensity to consume = 1
i.e. APC = 1
As we know the formula of APC ,

So, our equation becomes,

Hence, Disposable income = $100.
