An AMERICAN football field is 120 yards long. It is made up of a 100 yd long playing area bounded by a 10 yd end zone at either end. Since there are 36 inches in a yard, the playing area is (36 * 100) = 3600 inches long, and the entire field is (36 * 120) = 4620 inches long.

3600 inches

Step-by-step explanation:

100 yards=300 feet

300 feet=3600 inches

step-by-step explanation:

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
