we are given
we can use average rate of change formula from t=a to t=b
Here, we are given from t=1 to t=4
so, we will get formula as
now, we can plug values
now, we can simplify it
the average rate of change in the number of acres cleared for farming between t = 1 and t = 4 is 10 acres/ month.............Answer
Since the density is given in grams per cubic centimeter, we are going to convert the dimensions of the door to centimeters to calculate its volume in cubic centimeters.
We know that 1 meter = 100 centimeters and 1 centimeter = 10 millimeter, so we can use those conversion factors to convert from millimeters to centimeters and from meters to centimeters:
The volume of the layer of the paint will be height times wide time thickness, so:
Now, to find the mass needed to paint the door, we are going to use the formula:
where
is mass
is density
is volume
We know from our problem that
, and we know form our previous calculation that , so lets replace those values in our formula to find :
We can conclude that we will need 25200 grams of paint to paint the door.
