Question: Perform the indicated operations. In designing a building, it was determined that the forces acting on an I beam would deflect the beam an amount

Perform the indicated operations.

In designing a building, it was determined that the forces acting on an I beam would deflect the beam an amount (in cm), given by

x(1000 20x + x) 1850 -


where x is the distance (in m) from one end of the beam. Find the deflection for x = 6.85m. (The 1000 and 20 are exact.)
