Step-by-step explanation:
<h3> The complete exercise is attached.</h3><h3></h3>The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width.
Then, you can notice that it can be obtained by multiplying the dimensions of the rectangle.
Knowing this, you can determine that the total area of the two flowers bed can be obtained by adding the products of their dimensions.
Since one of the rectangular flower bed is 2.78 feet by 4.81 feet and the other bed 2.78 feet by 5.61 feet, you can write the following expression to find the total area (in square feet)of the two beds:
If you factor out 2.78:
or
Therefore, the expression that does not represent the total area in square feet of the two beds, is:
When an spherical balloon volume is increasing at the rate of then the diameter of the balloon is increasing
How can we find the rate of change of balloon's diameter ?
The volume of a spherical balloon is
In form of diameter we can write as
Now we will differentiate both sides wrt to we get
Given in the question
thus when we substitute the values we get
