Explanation It is given that the power gain G by a parabolic microwave dish varies directly as the square of the diameter d and inversely as the square of the wavelength λ of the wave carrier. The equation for the above statement is given by, G = k d 2 λ 2 .. ( 1 ) Where G denotes the power gain, d denotes the diameter, λ denotes the wavelength and k is the constant of proportionality. Also it is given that the power gain G is 5.5 × 10 4 for d = 2.9 m and λ = 3.0 cm . Substitute the given values in equation (1) to find the constant of proportionality k as follows. G = k d 2 λ 2 5.5 × 10 4 = k ( 2

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Early Monday morning, the temperature in the lecture hall has fallen to 40°F, the same as the temperature outside. At 7:00 A.M., the janitor turns on the furnace with the thermostat set at 72°F. The time constant for the building is = 3 hr and that for the building along with its heating system is 1 K A.M.? When will the temperature inside the hall reach 71°F? 1 = 1 hr. Assuming that the outside temperature remains constant, what will be the temperature inside the lecture hall at 8:30 2 At 8:30 A.M., the temperature inside the lecture hall will be about (Round to the nearest tenth as needed.) 1°F.
