For this case we have the following expression:
 h (t) = -16t ^ 2 + 64t + 80
 For t = 0 we have:
 h (0) = -16 (0) ^ 2 + 64 (0) + 80
 h (0) = -0 + 0 + 80
 h (0) = 80 feet
 Therefore the number 80 represents the initial height of the rocket

HELP ME PLEASE! HALF-DONE ANSWERS WILL BE DELETED! 15 POINTS!
Leni [432]

Answer:

G) Yes, because the plots and the linear model both align to produce a similar calculated sum.

H) I need to see the data table again for step 2d.

Step-by-step explanation:

1.) You scatter plot should be off by 6.97, since that was the first difference in your data table set of terms.

Basically subtract all of the GPAs from the Hours in the table.

Ex). Hours - GPA = Difference

or like before,

      9.2 - 2.23 = 6.97

Do the rest of the numbers like this then plot the answers.  I'd advise you plot your second set of scatter plot points in a different color.
