Ответ:
Step-by-step explanation:
The vertex will occur when t=-b/(2a) for the quadratic ax^2+bx+c
In this case
t=-200/(2(-16))
t=-200/-32
t=6.25
g(6.25)=-16(6.25^2)+200(6.25)
g(6.25)=625ft
So the maximum height of the rocket is 625 feet and it reaches this height at 6.25 seconds.
Ответ:
2x+2y = 8
2y = 8-2x
y = 4-x
y= -x+4
6x-3y = 12
-3y = 12-6x
3y = 6x-12
y = 2x-3
