Hello!
The residual for the point (5,1) is
To calculate residuals, we need to calculate the value of the line of best fit in the same x coordinate as the point we want to study to know the Predicted-y-value. To do so, we make the substitution of 5 into the equation:

Now we determine the residual with the following equation:

Have a nice day!
Answer:For the first one, it should be f(a)=37.8(1-cos(a))+.7. My dearest apologies because I do not know why. I just used context from the previous questions. I hope that helps..!

<h3>Hence, it will take 12 minutes by the printer to use all 96 sheets of paper.</h3>
Step-by-step explanation:
Given :
Tanya is printing a report.
There are 96 sheets of paper in the printer, and the number of sheets of paper p left after t minutes of printing is given by the function

When all the 96 sheets printed , then the number of sheets will left to print =0
Substitute p(t)=0 in the given function, to find the value of t, we get

<h3>Hence, it will take 12 minutes by the printer to use all 96 sheets of paper.</h3>
