The vertical velocity of the car at the given position and time is 4.905 m/s.
The given parameters:
- Initial angular velocity,
= 6.3 rad/s - Time of motion, t = 0.25 s
- Vertical displacement, y = 0.75 m
- Angular acceleration,
<h3>What is vertical velocity?</h3>
- This is the linear velocity of an object in a vertical direction.
The angular velocity of an object in a circular motion is given as;
The vertical velocity of the car at the given position and time is calculated as follows;
Thus, the vertical velocity of the car at the given position and time is 4.905 m/s.

Dattebayooo is the answer
An example of 7.2 connecting intercepts and linear factors is Graph y = x + 4 and y = x - 2 using a graphing calculator and then sketch the graphs on the grid.
<h3>What are linear factors?</h3>
The linear factors of a polynomial are known to be the first-degree equations that are said to be the framework of more complex and higher-order polynomials.
The Graph of y = x + 4 and y = x - 2 with the sketch of its graphs on the grid is shown in the image attached.

The sets A and sets B contains items called elements
It is true that the set A is equal to set B
<h3>How to determine the true statement?</h3>
The sets are given as:
Set A and set B
Since the sets have the same power set, then we have:
P(A) = P(B)
The above means that:
For every element X in A, then the element is also in B
And
For every element Y not in A, then the element is also not in B
So, we can conclude that:
All subsets of the set A are subsets of the set B and vice versa
Hence, the set A is equal to set B

The store that has a greater variety of numbers of wristbands sold is the store whose box plot has a greater IQR value.
<h3>How do we Determine Variability in a Box Plot?</h3>
- Variability of a data distribution that is represented by a box plot can be determined by the interquartile range (IQR) = Upper Quartile (Q3) - Lower Quartile (Q1).
- See the diagram attached below to understand how to get the Q3 and Q1 of the data distribution.
In conclusion, variability is a measure of IQR. The greater the IQR of a box plot, the greater the variety. Thus, the store that has a greater variety of numbers of wristbands sold is the store whose box plot has a greater IQR value.
