Provide an appropriate response.A pediatric speech therapist started her own practice in 2004. The function y = 3.2 x + 10.53 models the number of patients she treated each year, where x is the number of years after 2004. The model was found using data for the years between 2004 and 2012. What does the model estimate as the number of patients in 2014? Round to the nearest whole number. Is this interpolation or extrapolation?

Solve the problem.An experimental model for a suspension bridge is built. In one section, cable runs from the top of one tower down to the roadway, just touching it there, and up again to the top of a second tower. The towers are both 12.25 inches tall and stand 70 inches apart. At some point along the road from the lowest point of the cable, the cable is 1.1 inches above the roadway. Find the distance between that point and the base of the nearest tower.
