To begin with you multiply each term in the parentheses by each term in the second parentheses in the equation So then it would be

4x • 5x+4x • 2 + 4 • 5x+4 • 2

That then when you calculate it it would be

20x^2+8x+20x+8

Then you get the like terms.

20x^2+28x+8

If f(2) = 13 and f '(x) ≥ 2 for 2 ≤ x ≤ 7, how small can f(7) possibly be?​
timofeeve [1]

Answer:

23

Step-by-step explanation:

We are given that

f(2)=13

f'(x)\geq 2

2\leq x\leq 7

We have to find the possible small value of f(7).

We know that

f'(x)=\frac{f(b)-f(a)}{b-a}

Using the formula

f'(x)=\frac{f(7)-f(2)}{7-2}

f'(x)=\frac{f(7)-13}{5}

We have

f'(x)\geq 2

\frac{f(7)-13}{5}\geq 2

f(7)-13\geq 2\times 5

f(7)-13\geq 10

f(7)\geq 10+13

f(7)\geq 23

The small value of f(7) can be 23.

r = $1350 - $75m

Thus, the answer is letter C.
