Complete the square to rewrite y=x^(2)+8x+3 in vertex form, and then identify the minimum y-value of the function

vertex form: y=a(x−h)^2+k, (h,k) is the vertex

y=x^(2)+8x+3

 = (x+4)^2+3-4^2

 = (x+4)^2-13

hence, turning point for this function is (-4,-13)

minimum y-value = -13

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
