minus $3\mathrm{.}7$ percent grade intersects a plus $3\mathrm{.}4$ percent grade. The PVC station and elevation

are $145+10$ and $500$ ft$,$ respectively. The curve is $1,120$ ft long.

a$.(1$ point$)$ Sketch the curve. Label g$1,$ g$2,$ PVC$,$ PVI, PVT$,$ and L$.$

b$.(1$ point$)$ Determine the station of the PVI.

c$.(1$ point$)$ Determine the elevation of the PVI. Express your answer in feet.

d$.(1$ point$)$ Determine the station of the PVT$.$

e$.(1$ point$)$ Determine the elevation of the PVT$.$ Express your answer in feet.

f$.(1$ point$)$ Determine the station of the low$/$high point on the curve.

g$.(1$ point$)$ Determine the elevation $($in feet$)$ of the low$/$high point on the curve.

h$.(1$ point$)$ Determine the elevation at the first whole $100-$ft station on the curve $($e$.$g$.,$

$146+00).$ Express your answer in feet
