The height, h, in feet, of an object thrown upward from a height of 144 feet is a function of time, t, in seconds. The height ca
n be determined by the function h(t) -16t^2 + 128 + 144. The height of the object at 3 seconds is 384 feet. Why?
1 answer:
That should read:
h(t)=-16t^2+128t+144
h(3)=-16*9+128*3+144
h(3)=384

Answer:
4/5 (2x + 5) − 4 =1
4/5(2x +5) = 1 +4
4/5 (2x +5) = 5
2x + 5 = 5 / (4/5)
2x + 5 = 5 (5/4)
2x + 5 = 25/4
2x = 25/4 - 5
2x = 25/4 - 20/4
2x = 5/4
x = (5/4) / 2
x = (5/4) (1/2)
x = 5/8
x = 0.625

Answer:
x < -5
Step-by-step explanation:
- 2x - 7 > x+ 8
Add 2x to each side
- 2x+2x - 7 > x+2x+ 8
-7 > 3x+8
Subtract 8 from each side
-7-8 > 3x+8-8
-15 > 3x
Divide by 3
-15/3 > 3x/3
-5 >x
x < -5
The answer is g^-1= x^2/2 + 1/2
