Answer:
Is there a picture you are missing? We cant answer without knowing what the answer choices are.
Step-by-step explanation:
V = d/t
75 km/h = 480km /t
t = 480km / 75 km
t = 6.4 hours or 384 minutes
Answer:
1) the factored form is y= ( x-5 ) ( x+4 )
2) the vertex is (4.5, -0.25)
3) the y intercept is when x equals 0 so it is at (0,20)
4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is (0,20)
5)
a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)
b. it is taken at the vertex aka the lowest point so the height is -0.25
Coefficients are 2 and 3
Constant is M
