- Distance between cars At noon, car A is 10 feet to the right and 20 feet ahead of car B, as shown in the figure. If car A continues at 88 ft/sec (or 60 mi/hr) while car B continues at 66 f/sec (or 45 mi/hr), express the distance d between the cars as a function of t, where t denotes the number of sec- onds after noon. Exercise 78arrow_forwardA and B are points on the graphs of functions y1 and y2, respec-tively. Find the corresponding point on the graph of y = y1 + y2. A = (pi , - 0.5), B = (pi,-1)arrow_forwardFor the function y= 3 sin (2x-%), identify the amplitude, period, horizontal shift and vertical translation. Sketch TWO CYCLES of the graph of the function. Label the x-axis so that all of the "important points" are clearly identified. Amplitude Period Horizontal Translation Vertical Translationarrow_forward

Find the formula for the inverse of the function f.b. If the inverse is f -1, find f -1 (f (15)).arrow_forward
- Sinusoidal modeling: use your knowledge of amplitude, period, vertical translations, and horizontal translations along with your higher order of thinking skills to find functions that model the following.arrow_forwardBoyle's Law 2 states that for a certain gas in a container we have P. V = 350 where P represents the pressure of the gas (in mmHG) and V represents the volume of the gas (in liters). a. If the pressure of the gas is 240 mmHG, what is the volume of the gas? liters Preview b. Write a function f that determines the volume of the gas (in liters) in terms of the pressure of the gas in mmHG, P. f(P) Preview c. Complete the following statement. (Hint: if f(P) increases without bound, enter "oo". If f(P) decreases without bound, enter "- o0".) As P → 0*, f(P) → Previewarrow_forwardNeed only a handwritten solution only (not a typed one).arrow_forward
