The cables of a suspension bridge are in the shape of a parabola, as shown in the figure. The towers supporting the cable are 900 feet apart and 60 feet high. If the cables touch the road surface midway between the towers, what is the height of the cable at a point 225 feet from the center of the bridge?
The cable is feet from the road surface at a point 225 feet from the center of the bridge.

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
