Can someone me with this question

square root of (27)...which is 5.2"

Step-by-step explanation:

Slant height of the square pyramid,

Just take one side(triangle)

The slant height tends to divide the base of the triangle in 2,

; we take one half of the triangle,

which now has a side with 6" and a base of 3"(since it was divided in two by the slant height)

;then apply the pythagoras theorem,

; (slant height)^2 = ( 6^2 - 3^2)

; slant height = square root of (36 - 9)

; slant height = square root of (27)

; which is... 5.2"

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
