Answer:

It cooled 58.4 degrees

Step-by-step explanation:

T(t) = 68 + 144e ^(-.052t)

We want to find the value when t= 10

T(10) = 68 + 144e ^(-.052*10)

= 68 +85.611

T(10) =153.611

We also need to know

T(0)= 68 + 144e ^(-.052*0)

=68+144

=212

We want to know how much it cools

That would be the temperature at time 0 minus the temperature at time 10

T(0) - T (10)

212-153.611

58.389

To the nearest tenth

58.4 degrees
