Answer:
-0.16
Step-by-step explanation:
The 'a' value can be found by looking at the difference between the y-value of a point 1 unit from the vertex, and the y-value of the vertex.
Here, that is a negative fraction of a unit. If we assume the value is a rational number that can be accurately determined from this graph, then we can find it by looking for a point where the graph crosses a grid intersection. It looks like such grid points are (-7, 0) and (3, 0). The vertex is apparently (-2, 4), so the vertex form of the equation is ...
y = a(x +2)^2 +4
Using the point (3, 0), we have ...
0 = a(3 +2)^2 +4 . . . . . fill in the values of x and y
-4 = 25a . . . . . . . . . . subtract 4; next, divide by 25
a = -4/25 = -0.16
Answer:
4
Step-by-step explanation:
5 divided by 3 times
5/5/5=.2
.2*20=4
I'm really sorry if I'm wrong but
14*26=364 so he can go 364 miles for every full tank so his first 364 are covered since he starts with a full tank.
Step 2:
838/26*14 = <span>451

step 3:
He'd only have to stop once
