Determine what signs on values of x and y would make the statement true. Assume that x and y are not 0.
-If a rock falls from a height of 60 meters above the ground, the height H (in meters) after x seconds can be approximated using the formula $\mathrm { H } = 60 - 4.9 \mathrm { x } ^ { 2 }$ . What is the height of the rock after 3
Seconds?
A) -156.09 m
B) 495.9 m
C) 15.9 m
D) 45.3 m

Question

Quizplus · Accepted Answer

The height after 3 seconds is calculated as $ H = 60 - 4.9 \times 3^2 = 60 - 4.9 \times 9 = 60 - 44.1 = 15.9 $ meters.

Determine What Signs on Values of X and Y Would H=60−4.9x2\mathrm { H } = 60 - 4.9 \mathrm { x } ^ { 2 }H=60−4.9x2

Determine What Signs on Values of X and Y Would $\mathrm { H } = 60 - 4.9 \mathrm { x } ^ { 2 }$
