Answer:
See attachment for graph
The height of the arch is: 120 m
The width to the nearest meter, at the base of the arch is 22 m
Step-by-step explanation:
Given

Solving (a): The graph
See attachment for graph
Variable h is plotted on the vertical axis while variable d is plotted on the horizontal axis.
Solving (b): The height
The curve of
opens downward. So, the maximum point on the vertical axis represents the height of the arch,
Hence:

Solving (c): The width
The curve touches the horizontal axis at two different points.


The absolute difference of both points represents the width.
So:




Hence:

Answer:
3.51
3.52
3.53
etc.
Step-by-step explanation:
add numbers after 3.5
