Use a graphing utiiity to graph the function. If the function is periodic, find its period. If not, describe the behavior of the function as X increases without bound. y = sin(317x) + 3 cos(nx) The function is periodic. Its period is 37:. O The function is periodic. Its period is 2. O The function is periodic. Its period is 3. O The function is not periodic. As X > 00, y > 3. O The function is not periodic. As x a no, y a 00. X Use a graphing utility to graph the function. If the function is periodic, find its period. If not, describe the behavior of the function as X increases without bound. y = 95061" cos(0.25x) @ The function is periodic. Its period is 911. O The function is periodic. Its period is 811. O The function is not periodic. As x a 00, y a 9. O The function is not periodic. As X > 00, y > 0. O The function is not periodic. As x > oor y > 00. X A model for the height h (in feet) of a Ferris wheel car is h = 80 + 80 sin(4mf), where t is the time (in minutes). (The Ferris wheel has a radius of 80 feet.) This model yields a height of 80 feet when t = 0. Alter the model so that the height of the car is 1 foot when t = 0. (Assume that 1 foot is the minimum value of the model.) h= A surveyor in a helicopter is determining the width of an island, as shown in the figure. (Round your answers to the nearest whole number.) 5,000 ft Mu drum: in I die 6) (a) What is the shortest distance d (in ft) the helicopter must travel to land on the island? d-:. (b) What is the horizontal distance x (in ft) the helicopter must travel before it is directly over the nearer end of the island? (c) Find the width w (in ft) of the island. w=:
