Using a differential equation, it is found that the temperature dropped 72 degrees Celsius between sundown and 3 hours after sundown.
<h3>What is the differential equation that describes the temperature in t hours after sundown?</h3>
The rate at which the temperature is dropping is 
degrees Celsius per hour t hours after sundown, hence the <em>differential equation</em> is:
Applying <em>separation of variables</em>, we find the solution as follows:
In which T(0) is the temperature at sundown.
In 3 hours, the change will be of:
Hence:
The temperature dropped 72 degrees Celsius between sundown and 3 hours after sundown.

Answer:
Possible expressions are:
8x
8 * x
8(x)
8 · x
An = -2n(n + 3)
a(15) = -2(15)(15 + 3) = -30(18) = -540

Step-by-step explanation:
Dependent Variable
The dependent variable is the measured result of the experiment which are the values that change due to a change in the treatment applied in the experiment
The dependent variable is the output of the function of the experiment from an varied inputs to the experiment which is the independent variable
Independent Variable
The independent variable are the variable taken as the cause of the desired effect which is observed measured as the dependent variable
