In the arithmetic sequence (3, 7, 11, 15, ...), the common difference d and the 20th term (T_20) are respectively:

According to the Chain Rule, if y = (3 x² - 5)⁴, then dy/dx is:

The derivative of y = sin(3x) with respect to x is:

The equation of the tangent line to the curve y = x³ at the point (1, 1) is:

In a hydraulic press, the ratio of the cross-sectional area of the large piston to that of the small piston is 50. If a force of 100 N is exerted on the small piston, the maximum force exerted by the large piston is:

The relative density (specific gravity) of a substance is defined as:

In a hydraulic press, if the radius of the large piston is 4 times that of the small piston, the mechanical advantage is:
