Answer:
10x - 3y = -109 .
Step-by-step explanation:
x^2 + y^2 = 109
Implicit Differentiation:
2x + 2y.y' = 0
y' = -2x/2y = -x/y
So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.
Equation of the tangent:
y - y1 = m(x - x1)
y - 3 = 10/3(x + 10)
y - 3 = 10/3 x + 100/3
3y - 9 = 10x + 100
-109 + 3y = 10x
10x - 3y = -109
The answer is 4195.6. Hope this helps you :)

Answer:
120
Step-by-step explanation:
The function C(n, k) can be written in terms of factorials:
C(n, k) = n!/(k!(n -k)!)
Then ...
C(16, 2) = 16!//(2!(16 -2)!) = (16·15)/(2·1)
C(16, 2) = 120
