A22-in-long by 3.0-in-wide cast iron rectangular block is machined in a face milling operation using a 6.0-in-diameter cutter with 12 carbide inserts. the cutter path is centered over the width of the block. feed = 0.008 in/tooth and depth of cut = 0.60 in. at a cutting speed of 500 ft/min, the tool lasts for seven blocks. at a cutting speed of 250 ft/min, the tool lasts for 47 blocks. determine n and c in the taylor tool life equation. ignore the effect of the approach distance given by equation (21.18)

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.
