Answer:
3x(10x10x10): 3x(1000): 3000-7000: -4000. (8x(-5)): -40. (4x4) +(2x2): (16 +4): 20
Answer:
1. 14
Step-by-step explanation:
just solve for x.
17-2x = -11
-2x= -11-17
-2x= -28
2x = 28
x = 14
Answer:
Step-by-step explanation: This is for #6 Volume = pi·r2·h
Volume = pi·(5x+2)2(2x+8)
Answer:
17 seconds
Step-by-step explanation:
h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..
28 = -2t² + 34t + 28
Now solve for t...
0 = -2t² + 34t (subtract 28 from both sides)
0 = t² - 17t (divide both sides by -2)
0 = t(t - 17) (factor out a t)
So
t = 0
or
t - 17 = 0
t = 17
0 seconds is the initial height. At 17 seconds, the ball will return to that height
