The new perimeter will be 3 times the old perimeter.
Original perimeter:
2(8+7) = 2(15) = 30 yds
New perimeter once they are tripled:
3 x 8 = 24
3 x 7 = 21
2(24+21) = 2(45) = 90 yds
30 x 3 = 90
Answer:
Step-by-step explanation:
If you plot the vertex and the point, you see that the point is above the vertex. Therefore, this is a positive parabola with the work form of

We have values for x, y, h, and k. Let's write the equation of the parabola, put it into function notation, then find another x value at which to evaluate it.
and
and
8 = 9a - 1 and
9 = 9a so
a = 1. The equation of the parabola in function notation is

Since the vertex is at (3, -1) it would make sense to evaluate the function at x values close to the vertex. Let's evaluate the function at an x value of 4:
and
and
f(4) = 0. That means that another point on this parabola will be (4, 0).
The answer is c because of the graph going up
Answer:
1 = A. 2 = C
Step-by-step explanation:
the slope of the graphs have to be the dots that are on the x and go through the y.Hopefully i simplified what you had to do
