I got a Guinness can whose temperature is 21^(circ)C. To enjoy it cold at the perfect temperature of 9^(circ) C, I set my refrigerator to 0^(circ)C. The temperature T(t) of the can at time t measured in seconds satisfies Newton's Cooling Law equation: [dT]/[dt] =-.0001 T. How long will it take for the can to cool off to 9^(circ) C?

Answer asap evaluate 4-0.25g+0.5h4−0.25g+0.5h when g=10g=10 and h=5h=5.

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?
