Firstly, it is an arithmetic sequence.
d=-7 a1=5
a50 = 5-7*(50-1)
a50=-338
Pretty sure the slope would be -3.
Remark
The general equation for an ellipse is
At the center, the the point is 0,27
Solving for the

or b^2= 27^2 * 1
Taking the square root of both sides
b = 27
Now we need to use one more piece of information
The second point is (24,9) what that means is at the point x = 24, y = 9
Solving for that

576/a^2 + 81/729 = 1 Subtract 81/729 from both sides
576/a^2 = 1 - 81/729 = 576/a^2 = (729 - 81)/729 = 648 /729
576/a^2 = 648/729 Cross multiply
648 a^2 = 729 * 576 Divide by 648
a^2 = 648
Full equation for the ellipse and answer is
Answer: There are 120 different ways we can arrange reindeer.
Step-by-step explanation:
Since we have given that
Number of reindeer = 5
Number of them fly their sleigh = 4
We need to find the number of different ways we can arrange their reindeer .
For this we will use "Permutation":
here, n = 5
r = 4
So, it becomes,

Hence, there are 120 different ways we can arrange reindeer.
Answer:
3
