Answer:
y = (x - 2)^2 + 1
Step-by-step explanation:
The general equation of a parabola in vertex form is y-k = (x-h)^2. Here, we can see immediately from the graph that the vertex is at (2, 1). Thus, the equation of this particular parabola takes the form y - 1 = a(x - 2)^2. We must still determine the value of a. Note that the graph goes through (0, 5). Thus, 5 - 1 = a(0 - 2)^2, or
4 = 4a. Thus, a = 1, and the equation of this parabola is y - 1 = (x - 2)^2, or, after simplification, y = (x - 2)^2 + 1.
I think the answer is
Length = 10 and Width = 8
Let length be x+2 and width be x
x(x+2)=80
x=-10 or 8
The width cannot be negative so the width will be 8
The length is 8+2=10.
Divide the total amount traveled with the time it took.
21/3 = 7/1
Alba's average speed is 7 miles per hour
