H = -5t^2 +5t + 10
a) t = 0, h = 10 at time 0
b) h = (-5t + 10) ( t + 1)
c) put 0 in for the height and set each factor = to 0 and solve each
0 = (-5t + 10) and 0 = (t + 1)
solve each t = 2 and t = -1, so t = 2 sec is your solution
d) because a parabola is symmetric, the max will be half way between -1 and 2, at t = 1/2
h = -5(1/2)^2 +5(1/2) + 10
h = -5(1/4) + 5/2 +10
h = -5/4 + 5/2 + 10
h = -5/4 + 10/4 + 40/4
h = 45/4
A. Positive integer base 14
B. Exponent number 2
The answer is D) Seventh and eighth grade students at the school preferred an eagle mascot.
This is because both Tiger and Eagle had 40 votes, so it couldn't be A) or B), as they both had the same number of votes. It also couldn't be C) because more fifth and sixth grade students voted for tiger than eagle. It could only be D) as more seventh and eighth grade students DID actually vote for the eagle mascot rather than the tiger mascot.
