An unknown object(s) is(are) being imaged using a CT-type system. Projection data (attenuation profiles) for e = 0° and 0 =90° are showr below. Use given projection data to determine the approximate density distribution (shape) of the unknown object(s) and sketch the object(s) in thex-y coordinate system provided below. 0-90° 0-0°

4. The table shows the number C of cars in an office parking lot over the course of a work day. The time t is measured in hours, with t 0 representing 7:00am. 10 11 12 0. 1 3 6. 7 75 100 110 86 34 12 C 13 67 92 108 82 52 15 a) You want to write a sinusoidal model for the data in the table without using a graphing calculator. Is it more convenient to model the data with a sine or cosine function? Explain. b) Write a sinusoidal model for the number C of cars as a function of the time t (in hours) without using a graphing calculator. Identify and explain how you calculated your values for the amplitude, period, horizontal shift, and vertical shift. c) Use a graphing calculator to write a sinusoidal model that gives C as a function of t. d) Using your model from part (c), at about what time(s) will there be 45 cars in the parking lot?
