Hello:
an equation is : f(x) = a(x-0)² +0
the point (2 , -2)in parabola : -2= a(2-0)² +0
-2=4a
a =-1/2 is the coefficient of the squared expression in the parabola equation
<span>the vertex form is m f(x) = -1/2x²</span>
$2,447.67 - $231.49 = <span>$2,216.18
</span>$2,216.18 + $36.61 = $2,252.79
her new balance is $2,252.79
Get the perimeter of the each shape and add it all up to get the total fencing material required.
2 square flower beds = 2 x 4a = 8a
1 rectangular play ground = 2l + 2w
total fencing material = 8a + 2l + 2w
