A cake recipe says to bake the cake until the center is 180 degrees F, then let the cake cool to 100 degrees F. The table shows temperature readings for the cake.

a. Given a room temperature of 69 degrees F, what is an exponential model for this data set?
b. How long does it take the cake to cool to the desired temperature?
Please don't answer just for the points

answer:

22.5 minutes

Step-by-step explanation:

5 divided by 125 is five there for every 25 degrees  it goes up 5 minutes so from 71 that's only 2 degrees so 2 degrees divide by 5 is 2.5 add that to 20 for 22.5 minutes  

Good morning

answer: The cake would be 100F after about 47 minutes

Explanation:

Initial temperature = 210F

Time at 140F = 30 minutes

At 140F the cake has lost (210-140)F

= 70F

70F is lost on 30minutes

Rate of temperature reduction

= (70/30) F/min

= 7/3F/min

To lose 110F from 210 to 100F

Temp/time = 7/3

110/t = 7/3

Cross multiply

t = 330/7

t = 47.1429minutes ~ 47min

I hope this helps
