A contractor constructs a new rectangular-shaped deck and makes a scale drawing, where1 unit is equivalent to 1 foot. The contractor's customers want to triple the dimensions of thedeck, so the contractor must redraw the scale drawing.3.Exit Ticket-5/3/21What is the y-coordinate of point K' after the rectangle and point K are dilated by a scalefactor of 3 about the origin?

Dilation is a transformation in which image of the figure is same as original but sizes differ (…

Write a CNC G-code program to machine the part in the following figure, so that the tip of the tool follows this path: rapid movement to a point above P8, with z=4 . using absolute dimensioning change to tool "4, with a clockwise spindle speed of 2500 rpm, with coolant on and a feed rate of 14 in./min using incremental dimensioning -rapid movement to 4 in. above P1 -rapid movement to lower the tool to be 0.1 in. above the top surface of the part -move the tool to be 0.5 in. below the top at a 14 in./min feed rate -follow the path around the perimeter to points P2 through PI, ending at P1, using the 14in„/min feed rate turn off the spindle and coolant use absolute dimensioning to return to the start point end the program
Tsunami Waves and BreakwatersThis is a continuation of Exercise 16. Breakwaters affect wave height by reducing energy. See Figure 5.30. If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h=HR0.5, where R is the width ratio R=w/W. a. Suppose a wave of height 8 feet in a channel of width 5000feet encounters a breakwater that narrows the channel to 3000feet. What is the height of the wave beyond the breakwater? b. If a channel width is cut in half by a breakwater, what is the effect on wave height? 16. Height of Tsunami WavesWhen waves generated by tsunamis approach shore, the height of the waves generally increases. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk. Greens law tells how water depth affects the height of a tsunami wave. If a tsunami wave has height H at an ocean depth D, and the wave travels to a location with water depth d, then the new height h of the wave is given by h=HR0.25, where R is the water depth ratio given by R=D/d. a. Calculate the height of a tsunami wave in water 25feet deep if its height is 3feet at its point of origin in water 15,000feet deep. b. If water depth decreases by half, the depth ratio R is doubled. How is the height of the tsunami wave affected?
