Question 769994: As part of a screening process, computer chips must be operated in an oven at 145 °C. Ten minutes after starting, the temperature is 55 °C. After 5 more minutes, the temperature is 70 °C.
If you started heating the oven at 10:00 a.m., what time would the oven reach its operating temperature? Remember to label the time as a.m. or p.m.
Answer by josgarithmetic(39616)   (Show Source):
You can put this solution on YOUR website! The ordered pair data points are as (time, temperature) and you have only information for two points being: (10, 55) and (15, 70). You cannot make a quadratic fit with just two data points. You have no information given on the initial temperature at time 0 minutes. If you had it, the situation MIGHT be able to allow a quadratic fit and then a prediction for the time to reach 145 C.
Give the missing information for this problem.
