Wheelchair ramps require specific ratios of height to length to make them useable by people who use wheelchairs. In this project, you'll investigate the angles and distances of these ramps. The Americans with Disabilities Act (ADA) requires a slope of no more than 1:12 for wheelchairs and scooters for business and public use. Consider the following problem: A new store will need a ramp whose angle of elevation (the angle formed where the ramp touches the ground) is 3.5° and whose length is 36 inches. In triangle ABC, angle A is the angle of elevation and segment AC represents the ramp. Right triangle ABC marked with the given information and a right angle at angle B. © 2016 FlipSwitch. Created using GeoGebra. Does the ramp of the new store comply with the ADA? Why or why not? You will solve the problem step by step. Your progress has been saved Question 1 of 5 Refer to the problem. Which trigonometric ratio could you use to solve for BC, the height of the threshold to the store? cosB cosA sinB sinA

Time (minutes) amount of water (gallons) practice 1. jin fills up a 510-gallon pool in the backyard for her children. she fills it with the garden hose at a rate of 17 gallons per minute. after it is filled, she lets it sit for 30 minutes in order to let the water temperature rise. the children then get in and have fun for an hour. the pool loses about 5 gallon of water each minute due to their splashing and playing. at the end of the hour, they tear the pool while getting out, which causes a leak the pool then begins to lose water at a rate of 2 gallons per minute. a. complete the table to show the amount of water in the pool after each minute. b. create a graph to model the problem situation. include when the pool will be empty. c. write a piecewise function that models this problem situation. explain your reasoning for each piece of the function. d. identify the x- and y-intercept. explain what they mean in terms of the problem situation, atamantha a cul 80 100 120 150 200 ning, inc
