Write the expression as the sine, cosine, or tangent of an angle. sin 52° cos 13° – cos 52° sin 13° (6 points)

Find the measures of two angles, one positive and one negative, that are coterminal with the given angle. 263° (5 points)

Which of the following best describes a smeared-crack model?

Find the remainder when f(x) is divided by (x – k). f(x) = 3×4 + 11×3 + 2×2 – 7x + 61; k = 3 (5 points)

As the size of coarse aggregate increases, the roughness of the crack decreases. This allows higher shear stresses to be transferred across the crack.

Determine the transverse reinforcement index, Ktr, for a rectangular beam with b = 18 in. and d = 24 in., five epoxy-coated No. 6 Grade 60 tension-reinforcement bars placed in the top of the beam, and No. 3 Grade 60 stirrups located every 6 in. along the span. Assume 5,000-psi normal-weight concrete and a clear cover of 1.5 in.
