Which expression below gives the average rate of change of the function g(x)=-x^2-4x on the interval 6
Lapatulllka [165]

Answer:

The complete question is:

Which expression below gives the average rate of change of the function g(x)= -x^2 - 4x on the interval 6 < x < 8

When we have a function f(x), the average rate of change of this function in the interval a < x < b is given by:

r = \frac{f(b) - f(a)}{b - a}

Then if we have the function g(x) = -x^2 - 4x

and we want to find the average rate of change in the interval 6 < x < 8 we need to compute:

r = \frac{g(8) - g(6)}{8 - 6} = \frac{(-(8^2) - 4*8) - (-(6)^2 - 4*6)}{2} = \frac{-96 - (-60)}{2}  = \frac{-36}{2} = -18

9/15   divided by 27/30 =
Tema [17]

When dividing two fractions, we flip the second fraction and multiply by it (that is, use the reciprocal).

\frac{9}{15} ÷ \frac{27}{30}

= \frac{9}{15} × \frac{30}{27}

You can either multiply top by top and bottom by bottom or you can simplify by dividing out common factors.

= \frac{1}{1} × \frac{2}{3}

= \frac{2}{3}
