When two railroad tracks merge, the overlapping portions of the tracks are in the shape of a circular arc. The radius of each are r in feet and the angle theta are related by (x/2) = 2r(sin(theta/2)2. write a formula for x in terms of cos theta

Step-by-step explanation:

Given equation,

           ...... (1)

Since,

Thus,

 ...... (2)

From equation (1) and (2),

Which is the required formula.

step-by-step explanation:

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
