Answer:
Step-by-step explanation:
The rate of change is a measure in which one variable is modified in relation to another. In this case we have the variables:
Temperature in
Time in
Now, to calculate the rate of change, we have to divide one variable by the other. In this case the change in temperature divided by the time variation
.
Hence, assuming the ambient temperature of the glass is and the elapsed time
we have:
Answer:
Compound Interest
Step-by-step explanation:
When the interest is paid on principal amount only, then there is fixed return in case of a specified rate.
For example: Simple interest @ 5% on principal value of $100 shall be
$100 5% = $5 each year
Even though the interest amount is not withdrawn, and kept in the account earning this return.
Although, in case of compound interest:
Principal = $100
Rate = 5%
At the end of year 1, assuming interest is compounded each year
Value of interest = $100 5% = $5
Value of security or investment = $105
Second year interest = $105 5% = $5.25
Value = $105 + $5.25 = $110.25
Whereas in simple interest the value stays constant of principle on which interest is calculated = $100
Thus, total return in 2 years under simple interest = $100 + $5 + $5 = $110
Whereas that in compounded interest, compounded annually = $100 + $5 + $5.25 = $110.25
Thus, value of money increases faster in compound interest.
