A-4b that’s my answer hope this help
From the given information we can write the equation:
-16t^2 +96t + 4 = 112
-16t^2 + 96t + 4 - 112 = 0
-16t^2 + 96t - 108 = 0
simplify, change the signs, divide by -4
4t^2 - 24t + 27 = 0
You can use the qudratic formula but this will factor to
(2t-3)(2t-9) = 0
Two solutions
t = 3/2
t = 1.5 seconds at 112 ft on the way up
and
t = 9/2
t = 4.5 seconds at 112 ft on the way back down
Graphically, (green line is 112 ft)
2p-3=12p = 20
the answer is
p = 18
The total number of acorn squash that the farmer brought to the market = 80
Percentage of acorn squash was less when the day ended = 35%
Then
The amount by which the
number of acorn squash decreased at the end of the day = (35/100) * 80
= 280/10
= 28
Then
The number of acorn squash left with the farmer = 80 - 28
= 52
So from the above deduction, we can easily conclude that the farmer was left with 52 acorn squash at the end of the day.
