I will assume you mistyped this question. For y = -1/16x^2 + 4x + 3, the answers to this question are
a) 3 feet
b) 67 feet
c) 64.741 feet
For a) we note that at x = 0, that is the instant where the ball leaves the hand. y(0) = 0.
For b), we find the vertex of y = -1/16x^2 + 4x + 3
y = -1/16x^2 + 4x + 3
y = -1/16(x^2 - 64x) + 3
y = -1/16(x^2 - 64x + 1024 - 1024) + 3
y = -1/16((x-32)^2 - 1024) + 3
y = -1/16(x-32)^2 + 64 + 3
y = -1/16(x-32)^2 + 67
The vertex is at (32,67) so 67 is the maximum height.
For c), we find the x-intercepts with the quadratic formula on
y = -1/16x^2 + 4x + 3=0:
x = [ -b <span>± √b^2 - 4ac ] / (2a)</span><span>
x = [ -4 ± √4^2 - 4(-1/16)(3) ] / (2(-1/16))
x = -0.741, 64.741
Only the positive solution, so 64.741 feet </span>
I can only answer #8 and the answer is E
If you didn’t score high enough, you can retake the exams. But too many retakes might affect the chance of getting in the school you chose. Some things that can boost your admission to that school would be if you got a high GPA (Grade Point Average), recommendation letters from your teachers, or after school clubs that you have committed into doing. Most of these takes years to develop though.

Answer:
A. 1, 0
Explanation:
The standard deviation is a measurement of amount of variation in a given set of data. Mean is the average of given data set. Z-Score is the numeric value which determines relation to the mean measured in terms of standard deviation. The correct answer is A with mean 1 and standard deviation 0.
