The equation of the horizontal ellipse is 
Ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.
The standard form of an ellipse with horizontal major axis is:
Where a > b
since a = 12, b = 10, hence:
The equation of the horizontal ellipse is

You can get the tens digit of any number <em>n</em> by computing the quotient
(<em>n</em> (mod 100)) / 10
and ignoring the remainder.
Taking the given sum (mod 100) gives
7! + 8! + … + 2006! ≡ 7! + 8! + 9! (mod 100)
since the last 1997 terms (i.e. 10! up to 2006!) in the sum are multiples of 100. That is,
• every term beyond 100! is obviously a multiple of 100
• every term beyond 25! contains a factor of both 4 and 25
• every term beyond 10! contains two factors each of both 2 and 5 (i.e. every factorial term contains 4, 5, and 10)
The remaining sum is easy to compute by hand:
7! + 8! + 9! = 7! (1 + 8 + 8 × 9) = 5040 × 81 = 408,240
so the tens digit is 4.
Answer:
Im only in middle school, sorry
Step-by-step explanation:
I have tips tho!
always write information down, only useful ones, and not like "jimmy love to play basketball" kin of stuff.
Think it through, dont just guess.
Hope this helps i guess,

A^2 + b^2 = c^2
(6√2)^2 + (6√2)^2 = c^2
(36)(2) + (36)(2) = c^2
72 + 72 = c^2
144 = c^2
√144=√(c^2)
c = 12
