Answer: x=−1 or x=1 or x=−2 or x=3
Step-by-step explanation: Step 1: Factor left side of equation.
(x+1)(x−1)(x+2)(x−3)=0
Step 2: Set factors equal to 0.
x+1=0 or x−1=0 or x+2=0 or x−3=0
x=−1 or x=1 or x=−2 or x=3
Answer:
- a) 6.5 seconds
- b) 13 seconds
- c) 679 ft
Step-by-step explanation:
<u>Given function:</u>
a) <u>Maximum height is the vertex.</u> The ball reaches the maximum after:
- h = -208/2(-16) = 6.5 seconds
b) <u>Time the ball was in the air:</u>
Solving we get approximately t = 13 seconds
c) <u>Maximum height is at vertex, we found t above:</u>
- h(6.5) = -16(6.5)^2 + 208*6.5 + 3 = 679 ft
Answer:
1,961.6
Step-by-step explanation:
Answer:
Step-by-step explanation:
9 + 12m = 6 + 15m - 15
9 + 12m = 15m - 9
9 - 3m = -9
-3m = -18
m = 6
