1 A student uses data to find the quadratic regression function h = -0.811 + 19.931, which models an object's height, h, in meters, 1 seconds after it is launched upward from the surface of the moon. which is the best estimate of the height of a rock 3.1 seconds after it is launched? (​

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.
