Write the quadratic function in vertex form. y = x2 – 16x + 57 (5 points)

A simply supported beam with dimensions of b = 16 in., h = 28 in., d = 25.5 in., and L = 18 ft supports a uniform service (unfactored) dead load of 1.466667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The concrete is normal-weight concrete. The beam is reinforced with 3 No. 8 bars. The concrete strength is 8,200 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the maximum applied bending moment due to the combined service loads (dead plus live), Ma.      

Find the period of the function. y = -5 cos x (5 points)

A rectangular beam has a cross section of b = 16 in., h = 22 in., and d = 19.5 in. It is reinforced with two No. 7 Grade 60 bars. The concrete strength is 8,200 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the cracked moment of inertia, Icr. The neutral axis location of the cracked beam (measured from the top of the beam) is 3.6543 in.
