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.

A 125-mm-long beam supports a load of P = 40 N at midspan. The cross section is rectangular with width b = 30 mm and height h = 40 mm. Determine the magnitude of the horizontal shear stress at the centroid of the cross section.
