Answer:
C) -0.71m/s²
Step-by-step explanation:
V = V0 + at
V = final veloctiy
V0 = Initial velocity
a = acceleration
t = time
3 = 9 + a7
-5 = a7
= a
a ≅ -0,71
Sin x = 0.56976744186
Sin x = 4.9/8.6
x=10
You can use this equation to find the axis of symmetry or the vertex of the quadratic equation as long as it is in standard form
X= (-b/2a)
The answer is x=2
