Answer:
58 seconds
Step-by-step explanation:
Given the following :
Elevation of red Kite = 140 ft off the ground
Rising rate = 7 feets per second
Elevation of blue Kite = 315 feets
Rising rate of blue Kite = 4 feets per second
Determine how long will it take for the red and blue kites to be the same height.
Let number of seconds = t
Red Kite = 140 + 7t
Blue Kite = 315 + 4t
Red Kite = Blue Kite
140 + 7t = 315 + 4t
7t - 4t = 315 - 140
3t = 175
t = 175/3
t = 58.333
t = 58s (nearest tenth(
Answer:
b
Step-by-step explanation:
Given
![\frac{x^2-2x-3}{4x^2-12}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2-2x-3%7D%7B4x%5E2-12%7D)
Substitute x = 3 into the expression
= ![\frac{3^2-2(3)-3}{4(3)^2-12}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5E2-2%283%29-3%7D%7B4%283%29%5E2-12%7D)
= ![\frac{9-6-3}{36-12}](https://tex.z-dn.net/?f=%5Cfrac%7B9-6-3%7D%7B36-12%7D)
