Answer:
It took 8 seconds for the leaf to reach the ground.
Step-by-step explanation:
The height of the leaf in feet can be found using the function:
y = -3.5*x + 28
where x is the time in seconds the leaf has been in the air.
You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:
0= -3.5*x + 28
and solving you get:
-28= -3.5*x
(-28)÷ (-3.5)=x
8=x
<u><em>
It took 8 seconds for the leaf to reach the ground.</em></u>
The answer would be 1 1/7
The best approximation is 10 because the two closest perfect squares to 110 is 100 and 121. the one that's closest to 110 though is 100. the square root of 100 is 10.
C hope that helps have a good one and stay 28 - 6973
