For question number 1:The plot H = H(t) is the parabola and it reaches its maximum in the moment when exactly at midpoint between the roots t = 0 and t = 23. At that moment t = 23/2 or 11.5 seconds.
For question number 2:To find the maximal height, just simply substitute t = 11.5 into the quadratic equation. The answer would be 22.9.
For question number 3:H(t) = 0, or, which is the same as -16t^2 + 368t = 0.Factor the left side to get -16*t*(t - 23) = 0.t = 0, relates to the very start of the process, when the ash started its way up.The other root is t = 23 seconds, and it is precisely the time moment when the bit of ash will go back to the ground.

Answer:
The answer to your question is: 53 in²
Step-by-step explanation:
Area = ?
Process: divide the shape in one rectangle and one triangle.
Area of rectangle
A = base x height
A = 8 x 6
A = 48 in²
Area of rectangle
base = 13 - 8
= 5 in
height = 6 - 4
= 2 in
Area = (b x h) / 2
= (5 x 2) / 2
= 10 / 2
= 5 in²
Total area = 48 + 5 = 53 in²
