Concept explainers
(a)
The quadratic model for the data given below with the use of graphing utility.
s | 30 | 40 | 50 | 60 | 70 | 80 | 90 |
t | 2.7 | 3.8 | 4.9 | 6.3 | 8.0 | 9.9 | 12.2 |
Where t is the number of seconds the car takes to reach the speed s miles per hour.
(b)
To graph: The data and the quadratic model in part (a).
(c)
The reason why the model in part (a) is not appropriate for determining the time required to attain the speed of less than 20 miles per hour.
(d)
The quadratic model for the data given when a point
s | 30 | 40 | 50 | 60 | 70 | 80 | 90 |
t | 2.7 | 3.8 | 4.9 | 6.3 | 8.0 | 9.9 | 12.2 |
Where t is the number of seconds the car takes to reach the speed s miles per hour.
(e)
If the model in part (d) accurately model the behaviour of the car.
