Athermometer is taken from an inside room to the outside, where the air temperature is 20° f. after 1 minute the thermometer reads 70° f, and after 5 minutes it reads 45° f. what is the initial temperature of the inside room

Using the Newton's law of cooling principle, the initial temperature of the inside room would be 79.44°F

According to the Newton's Law of Cooling :

The equation can be expressed thus :

- - - (1)

- - - - (2)

Divide (1) and (2) - - -

Take the ln

k = 0.173

The initial temperature is defined thus :

Therefore, the initial temperature is 79.44°F

answer: the first graph

step-by-step explanation:

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
