A tortoise and a hare are competing in a 1600-meter race. The arrogant hare decides to let the tortoise have a 570-meter head start. When the start gun is red the hare begins running at a constant speed of 8 meters per second and the tortoise begins crawling at a constant speed of 5 meters per second. Let t represent the number of seconds that have elapsed since the start gun was red. a. Write an expression in terms of t that represents the hare's distance from the starting line (in meters). b. Write an expression in terms of t that represents the tortoise's distance from the starting line (in meters). : Preview c.

For any value of Ax measured away from the point (0, - 9) in the relationship, Ay = 2x. O Given any point (x, y) in the relationship, y is always 2 times as large as a. O The point (2, - 5) in the relationship conveys that 2 = 2( - 5) - 9. O Given any two points in the relationship (x1, y1) and (2, 32), y2 - yl = 2. 2 - 21 O The point (2, - 5) in the relationship conveys that - 5 = 2(2) - 9.

Determine if the following statements are true or false: ii The graph that represents 5 in terms of r is linear. iii 7, is proportional to 5. iii; AT is proportional to As iv; The graph of 'r in terms of s is a straight line that passes through the origin (0, 0). Submit Determine if the following statements are true or false. a. Select an answer v) The values of the independent and dependent quantity in a formula vary together. b. Select an answer | When defining m in terms of n, our goal is to write an expression using n that determines the value of m. C. Select an answer | Making a drawing of the quantities described in a problem context is often necessary for visualizing how quantities described in the problem are related. d. Select an answer | When asked to define the values of the dependent quantity, y, "in terms of" the values of the independent quantity, x, our goal is to construct an expression using the independent variable, x, that we can use to determine (or represent) the value of the dependent (or output) variable, y. SubmitA 14-inch candle is lit and burns at a constant rate of 1.3 inches per hour. Let t represent the number of hours that have elapsed since the candle was lit. :1. Write an expression in terms of t that represents the number of inches that have burned from the candle since it was lit. :| Preview b. Write an expression in terms oft that represents the remaining length of the candle (in inches). :| Preview Submit Determine if the following statements are true or false. a. Finding the constant rate of change of y with respect to m when we know two points in the relationship (3:1, yl) and A a ($2,312) requires determining the value of the ratio _y = u. Act: :02 7 ml b. The units for measuring a constant speed is always distance. c. The units for measuring a constant rate of change is a ratio of two quantities (e.g., meters/second). d. A constant rate of change is a measure of the relative size of two quantities as they change together. Submit Trent ran a marathon (a distance of 26.2 miles) in 4.5 hours. His watch told him that his average speed was thus about 5.82 miles per hour. What does this mean? Select the best answer. 0 Trent ran at a constant speed of about 5.82 miles per hour during the 26.2-mile race. 0 If Trent ran at a constant speed, he would have run about 5.82 miles per hour in order to complete the 26.2-mile race in 4.5 hours. 0 It is impossible for Trent to have maintained an exact constant speed during the race, so the average speed value has no meaning in this context. 0 For any change in time of one hour during the race Trent must have traveled about 5.82 miles.
