Solve the equaton backwards to get the answer
The standard equation for a parabola that opens upward parallel to the y-axis is x2=4ay, where a = distance from the vertex to focus. Vertex is at origin(0,0)
4a=2
a=2/4
a=1/2 or 0.5
the coordinate of the focus is (0, 1/2)
the equation of the directrix is y=-1/2
Answer:
They are 14.2 feet high each
Step-by-step explanation:
1136/80=14.2
2x+7=3x+3 is a linear equation with on solution
5 times 19-13 would equal 30 as 19-13 is 6 times 5 =30
