- A forest fire leaves behind an area of grass burned in an expanding circular pattern. If the radius of the circle of burning grass is increasing with time according to the formula r(t)=2t+1 , express the area burned as a function of time, t (minutes).arrow_forwardIf you travel 300 miles on the first day and then drive v miles per hour for t hours on the second day, then the total distance traveled over the teo-day period is given by d=300+vt miles. Use a formula to express v as a function of d and t for this two-day event.arrow_forwardBiorhythms A popular theory that attempts to explain the ups and downs of everyday life states that each person has three cycles, called biorhythms, which begin at birth. These three cycles can be modeled by the sine functions below, where t is the number of days since birth. Physical (23 days): P=sin2t23,t0 Emotional (28 days): E=sin2t28,t0 Intellectual (33 days): I=sin2t33,t0 Consider a person who was born on July 20,1995. (a) Use a graphing utility to graph the three models in the same viewing window for 7300t7380. (b) Describe the person’s biorhythms during the month of September 2015.

- Tide Heigh as a function resembles a sinusoidal function during time between low and high tide. At one such location on another planet with water, the tide has height of 10.7 feet at 2 AM and then the next low is -1.5 feet at 11AM (9 hours later). Find a formula for a sinusoidal function H(t) that gives the height at t hours after midnight. I used a cosine function for this function, so if anyone can explain this, I would appreciate it.arrow_forwardTide height as a function of time resembles a sinusoidal function during the time between low and high tide. At one such location on another planet with water, the tide has a high of 12.7 feet at 2 am and then the next low is -0.8 feet at 11 am (9 hours later). Find a formula for a sinusoidal function H(t) that gives the height tt hours after midnight.arrow_forwardTide height as a function of time resembles a sinusoidal function during the time between low and high tide.

- To calculate the amplitude for a function, take half the __________ of the___________ value and the __________ value of the function.arrow_forwardA ferris wheel is 27 meters in diameter and completes 1 full revolution in 8 minutes. A ferris wheel is 27 meters in diameter and boarded from a platform that is 1 meter above the ground. The 6 o'clock position on the Ferris Wheel is level with the loading platform. Th wheel conpletes 1 full revolution in 8 minutes. The function h(t) gives a person's height in meters above the ground t minutes after the wheel begins to turn. a. Find the amplitude, midline, and period of h(t). Enter exact answers b. Assume that a person has just boarded Ferris wheel from the platform and that the Ferris Wheel starts spinning at time t=0. Find a formula for the height function h(t). Hints: •What is the value of h(0) • Is this the maximum value of h(t), the minimum value of h(t), or a value between the two? • The function sin(t) has a value between its maximum and minimum at t=0, so can h(t) be a straight sine function? • The function cos(t) has its maximum at t=0, so can h(t) be a straight cosine…arrow_forwardSinusoidal 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_forward
