With simple harmonic motion, the reciprocal of the period is called the frequency. The frequency, given by f = 1/period represents the number of cycles (or oscillations) that are completed per unit time. The units used to describe frequency are Hertz, where 1 Hz = 1 cycle per second. In one country, the voltage of the alternating current coming through an electrical outlet can be modeled by the function V = 240 sin (130πt), where t is measured in seconds and V in volts. What is the frequency of the voltage?

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes. t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
