At higher elevations water boils at lower temperatures. The temperature at which water boils is called the boiling point of wate
r. At sea level the boiling point of water is 100oC, while at 2 kilometers of elevation (about 6550 feet) the boiling point of water is 94oC. The function that gives the boiling point of water in oC, B B
, at an elevation of x
x
kilometers is B(x)=100−3.5x
B(x)=100-3.5x
.
Determine the elevations at which the boiling point of water is between 84 oC and 88 oC. Give your answer accurate to 1 decimal place.
The boiling point of water is between 84 oC and 88 oC when the elevation is between
According to the question, the chair rises every 4 seconds 14 feet high. Therefore, the relationship between the chair and time is: the chair rises every 4 seconds.
