Answer:
(x+1)^2 + (y+1)^2 = 49
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x- -1)^2 + (y- -1)^2 = 7^2
Simplifying
(x+1)^2 + (y+1)^2 = 49
Each person gets 2 2/3 cups of ice-cream
Step-by-step explanation:
First, you convert 6 quarts to cups. For every quart, there are 4 cups so you do 6 times 4 and you get 24 then you divide 24 by 9 and you get 2 2/3
Answer:
The correlation coefficient is -1
Step-by-step explanation:
Here, we want to get the correlation coefficient for the given dataset
from the table, what do we observe?
As x is increasing by 5 units;
y is decreasing by 5 units
What this mean is that there is a negative correlation between both
Thus, what we have here is that, since the rate of increase/decrease on both ends is of equal magnitude but opposite signs, we can conclude that the correlation coefficient is -1
