Question Solved1 Answer R is the region bounded by the functions f(x)=3x2+27x+54 and g(x)=−3x22−27x2−27. Find the area A of R. Enter an exact answer.

Racing cars driven by Chris and Kelly are side by side at the start of a race. The table shows the velocities of each car (in miles per hour) during the first ten seconds of the race. Use the Midpoint Rule (with \( n=5 \) ) to estimate how much farther (in feet) Kelly travels than Chris does during the first ten seconds.

A post-tensioned bonded concrete beam has a prestress of 1560 kN in the steel immediately after prestressing which eventually reduces to 1330 KN. The beam carries two live loads of 45 kN each in addition to its own weight of 4.40 kN/m. a) Compute the extreme fiber stresses at mid-span under the initial condition with full prestress and no live load b) time dependent losses assume all need data) c) Compute the extreme fiber stresses at mid-span under final condition after all the losses have taken place and with full live load. 45kN 45kN 4.50m 3.00m 4.50m 300 009 GP.
