Y=v(initial)*t+1/2at^2
since the velocity is zero at the maximum height then we get
y=1/2at^2
a is just acceleration due to gravity so a=g which is 9.8 m/s^2.
so y=1/2gt^2.
Answer:
Step-by-step explanation:

To solving with their equation and expression to step by step.
3b/a-2
= -2a+3b/a
A: Equilateral
B: Obtuse
C: Obtuse
D: Right
E: Obtuse
F: Acute
A graphing calculator working the quadratic regression problem for these three points gives the equation as
y = 2x² +7x -5
