4. Here is a diagram of a softball field:
Edward wants to build a fence around the field and purchase turf to cover the
outfield. He does not know how much fence he will need or how much turn to
purchase.
250
a. Explain to Edward how to calculate the amount of fencing he needs to purchase.
b. Explain to Edward how to calculate the amount of turf he needs to purchase.
(Hint: Don't forget that the infield does not need to be covered)

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
