Answer:
39 square feet
Step-by-step explanation:
P = 2( L + W)
actual length = 4 * 3 = 12
actual width = 2.5 * 3 = 7.5
P = 2 (12 + 7.5)
P = 2 ( 19.5)
P = 39 feet
Answer: A (3, -4)
Step-by-step explanation:
A minimum is at the lowest point on the parabola. The minimum and maximum can be seen by looking at the vertex.
If you go right 3 spaces on the x-axis horizontally, then down 4 spaces vertically on the y-axis you get (3, -4).
4 is negative because you are going down below the x-axis.
