An object with initial temperature 120° F is submerged in large tank of water whose temperature is
1 answer:
Answer:
Step-by-step explanation:
<u>Newton's law of cooling states </u>
"<em>that the temperature of a body changes at a rate proportional to the difference in temperature between the body and its surroundings"</em>
Newton's Law of Cooling is given by the formula
Where
F( t ) is the temperature of the object at a given time t
T s is the surrounding temperature
T 0 is the initial temperature of the object
k is the constant
Given k=0.2
Hence the expression is

Answer: The answer is the picture shown below
Step-by-step explanation:
To do this you will need to make a coordinate plane about 20 up and 20 down. So there is a formula that is y=mx+b which is called the slope intercept form and as you can see the problem given to you was already given in this formula. The variable m in the equation is the slope and slope is also known as rise (which basically means go up if positive and down if negative) over run (which is right if positive and left if negative) and as you can see in the equation the number 4/5 is the variable m. Since slope is rise over run 4 would be the rise and 5 would be the run, so you would go up 4 and right 5 because they are both positive. Now there is another variable that is b which would be the -1. In slope intercept formula b is the y intercept so -1 is where the line would cross the y axis. Now that you know all the parts to the slope you can put it together giving you the answer.
