To solve this we are going to use the unitary circle and the fact that
From our circle we can infer that
and
.
Since
,
We can conclude that .
Answer:
so the difference is 84 - 63 = 21.
if we take 84 to be the 100%, what is 21 off of it in percentage?
Step-by-step explanation:
The answer is d because if you compare feet to yards 3 feet= 1 yard so divide 630 and 285 by 3 and then multiply them which ends up in 19,950. Your Welcome!
First, you will plot the point.
So, your first point will be (0,3) since that is the y intercept.
The next point would be (1,6)
Then (2,9)
Now, lets get the left
Another point would be (-1,0)
Then (-2,-3)
Now that you have those points, plot them, and draw a line
Part A:
For this case we have that the relationship between time and radius is linear.
We observe that for each day that passes, the radius increases two centimeters.
Therefore, the linear function is:
y = 2x
Since the linear function is exact, the correlation coefficient is:
r = 1
Answer:
r = 1
Part B:
As the linear function is:
y = 2x
So for days 1 and 2 the slope of the graph is:
m = 2
It means that the radius increases 2 centimeters per day.
Answer:
m = 2
Part C:
The data represents a correlation.
This is because the data follows a linear trend.
The radius always grows 2 centimeters for each day that passes.
Answer:
Correlation.
