53.9

Step-by-step explanation:

you add all of the sides up

178.07

Step-by-step explanation:

First you have to multiply 13 x 16 = 208. After that you have to find the area of the missing piece, to find that you have to add 5.7 + 6.2 = 11.9, and then subtract by 16 to get 4.1. Then you multiply 7.3 x 4.1 = 29.93.

29.93 is the area of the missing piece

So you would subtract the area of the whole thing (208) by the area of the piece (29.93)

To get the answer 178.07

0.02040816326

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
