Question

PRETTY PLEASE HELP ME !!!
Initiallly the ice cream's temperature is 0 degrees celsius. Six minutes later, it has warmed up to 8 degrees celsius. The temperature of the room is a constant 20 degrees celsius. Write an exponential function.

Answer 1

The refrigerator doesn't work.

Answer 2

$$\Huge y=e^{x}$$

Answer 3

It is a word problem for an exponential function for melting

Answer 4

@skullpatrol what would the x be

Answer 5

The variable looks like time.

Answer 6

I think SP's first answer works well, after all it doesn't ask for an exponential function that describes the situation.

Answer 7

yes it does ask to use the facts to write an exponential function

Answer 8

OK... 20-e^(-kx) = y (x in minutes, y in degrees)
then find k using 6,8

Answer 9

20-e^(-kx) = y
20-e^(-k*6) = 8
...
You got it yet?

Answer 10

I do not know how to solve for that
