What is the average rate of change of the function over the interval x = 0 to x = 8?

notsponge [240]

To find the average rate of change, use the following formula:

$\frac{f(b) - f(a)}{b-a}$

a and b represent the values of the interval:

$a = 0, b = 8$

Simplify the original equation by combining like terms:

$2x - 13x = -11x$
$f(x) = -11x + 5$

Plug the interval values into the f(x) equation:

$f(0) = -11(0) + 5 = 0 + 5 = 5$
$f(8) = -11(8) + 5 = -88 + 5 = -83$

Plug in these values into the average rate of change formula:

$\frac{-83 - 5}{8 - 0} = \frac{-88}{8} = -11$

The average rate of change over this interval is -11.

Clara is building a triangular garden. She wants the length of the longest side to be three more than twice as long as the lengt

pantera1 [17]

Alrighty-
So here we go.
Let's first go over any given values.

Shortest side = s

And we know that
3rd side = 12

Now for the longest side
"Three more" means +3
"...twice as long as the shortest side"
Means 2s

Longest side = 3+2s

Now we put this in the correct format:

P = 12 + s + (3+2s)

We can simplify further:
P = 12 + s + 3 + 2s
P = 15 + s + 2s
P = 15 + 3s

ANSWER: P = 12 + s + (3+2s)

SIMPLIFIED: P = 15 + 3s
