I think it might as while be C or sum
<span>h= (-16t^2 + 28t + 7) </span>
find the derivative to get time<span>
<span>
h' = (-32t + 28)
When the ball reaches its maximum height, its
vertical velocity (h’) will be 0 </span></span>
<span>
<span>
0 = -32t + 28 </span></span>
-32t=-28
<span><span>-28/-32 = </span>0.875
seconds </span><span>
<span>
The ball reaches its maximum height in 0.875
seconds after being thrown; plug and chug and:
h= (-16(0.875)^2 + 28(0.875) + 7) = 19.25 feet</span></span>
Max height = 19.25 feet, time = 0.88 seconds
Answer:
BC = 25
Step-by-step explanation:
If the base angles are equal, then the sides opposite them are as well.
- 4x + 4 = 6x - 14 Subtract 4x from both sides
- 4x - 4x + 4 = 6x - 4x - 14 Combine
- 4 = 2x - 14 Add 14 to both sides
- 4 + 14 = 2x - 14 + 14 Combine
- 18 = 2x Divide by 2 and switch
- 2x/2 = 18/2 Combine
- x = 9
But that's not what you are asked for. You want the value of 2x + 7
- BC = 2x + 7
- BC = 2*9 + 7
- BC = 25
Answer:
2
