Answer:

-8

Explanation:

The instantaneous rate of change when x = 2 is equal to the slope of the tangent line at that point. So, we need to find the slope of the following line

Using two points (x1, y1) and (x2, y2) of the line, we can calculate the slope as follows

m=\frac{y_2-y_1}{x_2-x_1}

So, replacing (x1, y1) by (2, -8) and (x2, y2) by (1, 0), we get:

m=\frac{0-(-8)}{1-2}=\frac{0+8}{-1}=\frac{8}{-1}=-8

Therefore, the estimate of the instantaneous rate of change is -8.

\displaystyle\bf \bigg(\frac{625}{81} \bigg)^{-\frac{1}{2} }=\bigg(\frac{25}{9} \bigg)^{-2\cdot\frac{1}{2} }=\bigg(\frac{25}{9} \bigg)^{-1}=\boxed{\frac{9}{25} }

Daniel is working two summer jobs, making $8 per hour babysitting and making $15 per hour lifeguarding. In a given week, he can
natima [27]
If he makes $8 per hour while babysitting, then if he works 3 hours - then he’d get $24 for babysitting.

He still has to make $176.
He can work 18 hours, if he uses up 3 hours babysitting, he has 15 hours left.

15 hours times $15 = 225 (too much)
12 hours times $15 = $180 ( he saves three hours)

He has to do 12 hours of life guarding to meet his goal - he will have three spare hours.

Sorry if I’m wrong, I think I’m right tho
