Answer: About 6.71 units

Step-by-step explanation:

You use the distance formula: $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }$ .

Assign the the two points to the variables:

$(x_{1}, y_{1}) = (1, 3)\\(x_{2}, y_{2}) = (4, -3)$

Substitute them in the formula:

$\sqrt{(4-1)^{2}+(-3-3)^{2}}$

And solve it:

$\sqrt{(4-1)^{2}+(-3-3)^{2}}\\=\sqrt{(3)^{2}+(-6)^{2}}\\=\sqrt{9+36}\\=\sqrt{45}\\=6.71$

Find the average rate of change for the given function over the indicated values of x. If necessary, round your final answer to

Pavlova-9 [17]

Answer:

The average rate of change of the function in this interval is of 18.

Step-by-step explanation:

The average rate of change of a function $f(x)$ in an interval from a to b is given by:

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

In this question:

$f(x) = x^2 + 6x$

Where x goes from 5 to 7.

This means that $b = 7, a = 5$ . So

$f(7) = 7^2 + 6(7) = 49 + 42 = 91$

$f(5) = 5^2 + 6(5) = 25 + 30 = 55$

The rate of change is:

$A = \frac{f(7) - f(5)}{7 - 5} = \frac{91 - 55}{2} = 18$

The average rate of change of the function in this interval is of 18.
