Answer:
the answer is 16.5
Step-by-step explanation:
7.50 x 16.5 = 123.75
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.
To answer to the question above, when adding or subtracting measurements (numbers), the result must have the same number of decimal places as the number in the problem with the fewest decimal places.
<span>24.545 + 307.3 = 331.845</span>
However, the answer must be given to the correct number of decimal places, in this case, 1 in 307.3.
So the result of the addition of 24.545 and 307.3 should be 331.8.
