<u>Given</u>:
The perimeter of a polygon is the sum of the lengths of the sides of the polygon.
Given that the sides of the polygon are x + 1, 3x - 2, 3x - 2, x + 1.
We need to determine the perimeter of the polygon.
<u>Perimeter of the polygon:</u>
The perimeter of the polygon can be determined by adding the lengths of the sides of the polygon.
Thus, we have;
Removing the parenthesis, we get;
Adding the like terms, we get;
Thus, the perimeter of the polygon is
Answer:
All the options are correct.
Step-by-step explanation:
Holly begins with 1 penny in her piggy bank. She adds 2 pennies on day 1, 4 pennies on day 2, and 8 pennies on day 3. She continues this pattern for 30 days.
The pattern which she choses is where n denotes the number of days.
A)
The graph of this sequence would pass the vertical line test.
" Vertical line test: A function can only have one output, y, for each unique input, x " .
Here also y=2^n and x=n.
B)
Each day corresponds to a unique amount of pennies in this sequence.
Since the sequence is increasing, hence option B is correct.
C)
The graph of this sequence would pass the horizontal line test.
A test use to determine if a function is one-to-one.
As for each n we get a unique value.
Hence, option C is correct.
D)
Each amount of pennies corresponds to a unique day in this sequence.
This option is also true as each amount is a function of number of days.
