Step-by-step explanation:
Answer:
4 cm
Step-by-step explanation:
Perimeter of a parallelogram is 2b+2h=30 where b is base and h is height.
if AD is 3cm more than twice AB, then it's 3+2x where x is length of AB.
Input this into the perimeter equation: 2(3+2x)+2(x)=30
Simplify to get 6+6x=30
x=24/6=4
Answer is 4 cm.

<h2>
Hello!</h2>
The answer is:
The range of the function is:
Range: y>2
or
Range: (2,∞+)
<h2>
Why?</h2>
To calculate the range of the following function (exponential function) we need to perform the following steps:
First: Find the value of "x"
So, finding "x" we have:

Second: Interpret the restriction of the function:
Since we are working with logarithms, we know that the only restriction that we found is that the logarithmic functions exist only from 0 to the possitive infinite without considering the number 1.
So, we can see that if the variable "x" is a real number, "y" must be greater than 2 because if it's equal to 2 the expression inside the logarithm will tend to 0, and since the logarithm of 0 does not exist in the real numbers, the variable "x" would not be equal to a real number.
Hence, the range of the function is:
Range: y>2
or
Range: (2,∞+)
Note: I have attached a picture (the graph of the function) for better understanding.
Have a nice day!
