Step-by-step explanation:
Answer:
The distance of the side of the picture from the edge of the wall is 8.5 inches
Step-by-step explanation:
see the attached figure to better understand the problem
Let
x -----> distance of the side of the picture from the edge of the wall
we know that
The wide of the wall must be equal to the wide of the picture plus two times the distance of the side of the picture from the edge of the wall
so
The linear equation that represent this situation is
solve for x
therefore
The distance of the side of the picture from the edge of the wall is 8.5 inches
We have that
x² = 8y-------> y=(1/8)*x²
we know that
the equation of a parabola is of the form
y=a(x-h)²+k
in this problem
a=1/8
(h,k)--------> is (0,0)------> is the vertex of the parabola
a > 0--------> the parabola opens up
therefore
the answer is
<span>the value of a is (1/8)</span>
