=Tx+-2141e-0.45x

Question

A can of soda is placed inside a cooler. As the soda cools, its temperature
Tx
in degrees Celsius is given by the following function, where
x
is the number of minutes since the can was placed in the cooler.

=Tx+−2141e−0.45x
Find the initial temperature of the soda and its temperature after
15
minutes.
Round your answers to the nearest degree as necessary.

Answer 1

And to find the initial temperature, all you have to do is evaluate T when x=0.

Answer 2

you miss typed the equation dear,

is the equation like this?

T(x)=-2141e^-0.45x

if this the correct equation you plug in the value 15 for x in the equation given

T(15)=-2141e^-0.45(15)

T(15)=-2.51 ° C
