 Question 745041: I have this problem: A roof shingle is dropped from a rooftop that is 100 feet above the ground. The height y (in feet) of the dropped roof shingle is given by the function y=-16t^2+100 where t is the time (in second)s since the shingle is dropped. Graph the function. I have worked out that if I solve for t, t=2.5. But how do I proceed in graphing? My teacher doesn't explain anything and this problem is on my review sheet. We didn't ever see word problems like this in the chapter. Any help you can give me would be very much appreciated. Click here to see answer by mananth(13127)

 Question 746086: I need help solving this Quadratic equation problem. I would appreciate it... If someone who may help walk me through steps to solving this problem. I need to learn this for my final that's coming up. [Travel Speed (mph), Braking Distance (ft)] [20(mph), 20 (ft)] [40(mph), 105 (ft)] [60(mph), 300(ft)] a)Find a quadratic function that fits the data on the right. b) Use the function to estimate the braking distance of a car that travels at 50 mph. c) Does it make sense to use this function when speeds are less than 10 mph? Why or why not? y=ax^2+bx+c [20(mph), 20 (ft)] (20)=a(20)^2+b(20)+C = 20=400a+20b+C [40(mph), 105 (ft)](105)=a(40)^2+b(40)+C = 105=1600a+40b+C [60(mph), 300(ft)] (300)=a(60)^2+b(60)+C = 300=3600a+60b+C Click here to see answer by stanbon(60778)
