Write the equation of a function h(t) that represents the amount of heat in joules required to heat the bar to a temperature of t degrees Celsius.

Respuesta :

The initial temperature of the bar is 25. To get to the t temperature you need to add (t-25) degrees Celsius.

for 1 degree................... 7 Joules
      y given degree........  p Joules

p=7y

In our case y=(t-25) .

h(t) = 7(t-25) which is the final answer.
