2001. Use the data points to find a linear function that fits the data Use the function to predict the average salary in 2005 and 2010 Data points: (1,275000) (11,1490000) 1,460,000-275,000/11-1 M= 118,5000 Y-275,000= 118,500(x-1) Y-275,000 = 118,500x-118,500 Y = 118,500x-118,500+275,000 Y= 118,500x+156,500 Linear Function S(x)= 118,500x+156,000 The predicted average salary for 2005 is S(15)= 118,500(15)+156,000 S(15)= 1,933,500 The predicted average salary for 2010 S(20)= 118,500(20)+156,000 S(20)= 2,526,000 Determine whether the graphs of the two equations are perpendicular: Y= 9x-9 6y=7-x Y=9x-9 Slope is 9 6y= -x+7 Y= -1/6+7/6 Slope is -1/6 The graphs of the given equations are not perpendicular because the slopes are not negative reciprocals of each other The function, p(d) = 1+d/33, gives the pressure, in atmospheres (atm), at a depth d in the sea (d is in feet). Note that p(0)=1atm, p(33)=2, and so on. Find the pressure at 190 feet
