Question

HELP!!!!

Answer 1

A pan is heated to 370°F, then removed from the heat and allowed to cool in a kitchen where the room temperature is a constant 71°F. The formula below can be used to find D, the difference in temperature between the pan and the room after t minutes.

D = 299e-0.02t

What is the approximate temperature of the pan after it has been away from the heat for 15 minutes?

Answer 2

221.5°F
474.6°F
292.5°F
150.5°F

Answer 3

can you help?

Answer 4

what does the variable e stand for?

Answer 5

I don't know.

Answer 6

first plug in 0.02 * 15

Answer 7

done it equals -0.3

Answer 8

But I legit can't find what e is supposed to stand for. Like I know t = time/minutes...

Answer 9

is that how the equation was first written?

Answer 10

yes.

Answer 11

ok, I'm stuck, sorry :/

Answer 12

\(e\) stands for Euler's number which is equal to 2.7182818284590452353602874713527 but for this we will just use 2.7182

Answer 13

so now that we know what \(e\) is what is -.02*15

Answer 14

Answer 15

it's A

Answer 16

Thank you very much, I had no idea that such a thing as Euler's number even existed.
