Answer: 52 meters
Step-by-step explanation:
You have to multiply 8•13 which gives you 104 then you have to divide that by 2 and you get 52
The equation models the height of the ball correctly will be h = -16t² + 40t.
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
A soccer ball is kicked into the air from the ground.
g = 9.81m/s²
g = 9.81/0.3048
g =32.18.. ft/s² rounded to 32
h = -g/2t² + vt + h0
if t = 0,h = 0
h = -16t² + vt
50 ft in 2.5s
25 ft in 1.25s
25 = -16 x 1.25² + v x 1.25
v = 50/1.25
v =40
The equation models the height of the ball correctly will be h = -16t² + 40t.

The answer is D, i.e. the system was solved via elimination
If you multiply the first equation by 5, the system becomes
If you sum the two equations, you get
And so if you substitute the second equation of system A with this new equation, you'll get system B.
How do I find the vertex of this function?
Answer:
(-6,-69)
Step-by-step explanation:
y=2x^2 + 24x + 3
=2(x^2+12x+36)-2*36+3
=x(x+6)^2-69
vertex: when x=-6. y=-69
