Answer:
T = 20
min = 1
max = 0
Step-by-step explanation:
In the first image, the period is calculated by measuring the distance on the x-axis that it takes for the function to complete a cycle.
The attached image shows a way to measure the period, marking the distance from x = 0 until the wave completes the rise and fall cycle at x = 20.
Therefore the period is 20.
In the second image it can be seen that the lowest peak of the function is y = 1. The function is never less than y = 1. Therefore, that value is the minimum.
In the third image it can be seen that the maximum value of the function is y = 0. Since it is the maximum value that reaches the top peak

<u>Density</u>
The density of an object of mass m and volume V is given by
It can be expressed in common units like or any other combination of proper mass [M] by volume [V] units.
The data provided in the question is
Thus, the measured density is
We have expressed the result with 1 decimal place because the mass was measured to the nearest hundred milligrams (or one-tenth grams). Any further decimal is senseless because that precision comes from calculations, not from measurements.
