Given:
The width of a rectangle is x centimeters and its length is (x+ 2) cm.
To find:
The expression for the perimeter of the rectangle.
Solution:
We know that, perimeter of a rectangle is
We have,
Width = x cm
Length = (x+2) cm
Putting these values in the above formula, we get
Therefore, the required expression for the perimeter of the rectangle is (4x+4) cm.
Answer:
1. . Exponential decay function.
2. . Exponential growth function.
3. . Exponential growth function.
4. . Exponential growth function.
5. . Exponential growth function.
6. . Exponential decay function.
7. g(x) = 0.3(x). Not an exponential function.
Step-by-step explanation:
1. . This is an exponential decay function.
As the value of t increases H-value decreases.
2. . This is an exponential function of growth.
As the value of t increases y-value also increases.
3. . This is an another example of exponential growth function.
As the value of t increases f(t)-value also increases.
4. . This is again an example of exponential growth function.
As the value of t increases A-value also increases.
5. . This is again an example of exponential growth function.
As the value of t increases A-value also increases.
6. . This is another an example of exponential decay function.
As the value of t increases, H-value decreases.
7. g(x) = 0.3(x). This is a non-exponential function. (Answer)
