Answer:

C. f has a relative maximum at x = 1.

Step-by-step explanation:

A. False.  f(x) is concave down when f"(x) is negative.  f"(x) is the tangent slope of the graph, f'(x).  So f(x) is concave down between x = -1.5 and x = 1.5.

B. False.  f(x) is decreasing when f'(x) is negative.  So f(x) is decreasing in the intervals x < -3 and 1 < x < 2.

C. True.  f(x) has a relative maximum where f'(x) = 0 and changes from + to -.

Solve the following equation for a. <br> -4G+1/8Qa=7<br> Answer: a=?
kolbaska11 [484]

By making a the subject of formula in the given equation, the value "a" is equal to 1/(56Q + 32GQ).

<h3>What is an equation?</h3>

An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.

In this exercise, you're required to solve for a from the given mathematical expression (equation) by making it the subject of formula. This ultimately implies that, all the other variables would be defined in terms of a and they would all be on the same side of the "equal to" symbol.

Making a the subject of formula, we have:

-4G + 1/8Qa = 7

1/8Qa = 7 + 4G

Multiplying both sides by 8Q, we have:

8Q × 1/8Qa = (7 + 4G) × 8Q

1/a = 56Q + 32GQ

a = 1/(56Q + 32GQ).

Answer:

Square root(9),PI, 22/7, 3 1/5 OR square root(9), PI,22/7, 3 1/5

Step-by-step explanation:

First off lets simplify

sqaure root of 9 is =3

22/7 = 3 1/7

And if you notice 3 1/7 and pi are EXACTLY the same.

3 1/5 = 3.2

Final pairings:

Square root(9),PI, 22/7, 3 1/5

OR

square root(9), PI,22/7, 3 1/5

Once again pi and 22/7 are the same.

Hope this helped :)))
