Answer:
When t=2.1753 & t=.5746 , h=27
Don't worry, I got you. Also, my calculator does too.
We set h equal to 27, because we want the height to be 27 when we solve for t.
That leaves us with:
27 = 7 + 44t - 16t^2
Simplify like terms,
20 = 44t - 16t^2
Move 20 onto the right side, so we can use quadratic equation
44t - 16t^2 - 20 = 0 --> -16t^2 + 44t - 20
Using quadratic, you get
t=2.1753 & t=.5746
<u>poster confirmed : "It’s t=2.18 and t=0.57"</u>
Well to get to 32 hours and knowing for all 4 days, she worked the same number of hours.
All we have to do is multiply all these numbers by 4 to see which one is equal to 32.
6 * 4 = 28
10 * 4 = 40
8 * 4 = 32
4 * 4 = 16
