Answer: Period = 4
Amplitude = 3
<u>Step-by-step explanation:</u>
Period is the interval of one "cycle" before the pattern repeats.
If you notice that when x = 0, y = -4.
When does the pattern repeat (reach -4 again)?
Answer: when x = 4.
So the interval of one "cycle" is 4 units --> Period = 4.

True the circle is a congruent to the radius of an inscribed regular polygon inside the circle
Answer:
LQ = 54
Median = 69
UQ = 94
Step-by-step explanation:
This list is already sorted for you, so you don't need to worry about that, otherwise you would need to sort the numbers in ascending order. To find the median, we do
, where n is the amount of numbers. This gives us 4, so the median is at position 4, so the median is 69. The lower quartile is simply
, so 2, so the lower quartile is 54. The upper quartile is
, so 6, so the upper quartile is 94.
The answer is (7,2) and 45 units squared.
