wouldn't it be H(t)= -16(0.9)^2 + 30 (0.9) plus 32? Which would get the final vertex point Approx: (0.9, 44.1) ? When it's graphed on desmos it gives the exact point that I just mentioned.

List the sides of δrst in in ascending order (shortest to longest) if: a ∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°

You were told that the amount of time lapsed between consecutive trades on the new york stock exchange followed a normal distribution with a mean of 15 seconds. you were also told that the probability that the time lapsed between two consecutive trades to fall between 16 to 17 seconds was 13%. the probability that the time lapsed between two consecutive trades would fall below 13 seconds was 7%. what is the probability that the time lapsed between two consecutive trades will be between 14 and 15 seconds?

Icould really use some with this question.
