Answer:
A = 615.75
cost = $107.08
Step-by-step explanation:
the training area = (28/2)^2*pi
training area = 615.75 square feet
615.75/5.75 = 107.08
$107.08
Answer: y=2/3x+1
Step-by-step explanation:
y=2/3x-6
y=2/3x+b ==> Parallel to y=2/3x-6 since they both have the same slope
3=2/3 (3)+b
3=2*3/3 +b
3=6/3 +b
3=2+b
b=1
y=2/3x+1
b^2-4ac<0 b^2-144<0 (b-12)(b+12)<0
-12<b<12
