Answer:
![y=-67.5[cos(\frac{\pi}{15}t)-1]](https://tex.z-dn.net/?f=y%3D-67.5%5Bcos%28%5Cfrac%7B%5Cpi%7D%7B15%7Dt%29-1%5D)
Step-by-step explanation:
We can start solving this problem by doing a drawing of London Eye. (See attached picture).
From the picture, we can see that the tourists will start at the lowest point of the trajectory, which means we can make use of a -cos function. So the function will have the following shape:
where:
A=amplitude
= angular speed.
t= time (in minutes)
b= vertical shift.
In this case:
A= radius = 67.5 m
where the frequency is the number of revolutions it takes every minute, in this case:
so:
and
b= radius, so
b=A
b=67.5m
so we can now build our equation:
which can be factored to:
You can see a graph of what the function looks like in the end on the attached picture.
Answer:
The median, because the data distribution is skewed to the right
Step-by-step explanation:
Min= 10.5
Q1 = 11.5
Median = 12.5
Q3= 13.5
Maximum = 15
The data is skewed towards the right because more values towards the right side as compared to the left side.
For data to be symmetrical, it has same shape on both sides of the median, which in our case is not possible.
So, for skewed data we always prefer median because it is less affected by the outliers and if mean is chosen, the value of mean is biased towards the side that has larger values while median does not get affected by it. So, we choose median.
our correct option will be:
The median, because the data distribution is skewed to the right
Answer:the domain is every “x” coordinate and the range is the “y” coordinate
Step-by-step explanation:
If you have to tell whether it’s a function or not, all of the x values in the domain will be different for a function, and 2 or more of the same x value won’t be a function

That's it right there
I believe It would be back in the 4th quad bc 360 is a full circle
