The complete question is
find the slope of the tangent line and the equation of the tangent line at the given point, ![x^2y-5xy^2](https://tex.z-dn.net/?f=x%5E2y-5xy%5E2)
at the point (3,1).
Answer:
Tangent = 1/23 , equation of tangent = 23y - x = 20
Step-by-step explanation:
We are given the equation
![x^2y-5xy^2](https://tex.z-dn.net/?f=x%5E2y-5xy%5E2)
![+6=0](https://tex.z-dn.net/?f=%2B6%3D0)
upon differentiation the given function we get
d (![x^2y-5xy^2](https://tex.z-dn.net/?f=x%5E2y-5xy%5E2)
) /dt
= ![2xy +x^2dy/dx - 5y^2 -10xy dy/dx =0](https://tex.z-dn.net/?f=2xy%20%2Bx%5E2dy%2Fdx%20%20-%205y%5E2%20-10xy%20dy%2Fdx%20%3D0)
upon substituting x=3 ,y=1 we will get
dy/dx = 1/23
now the equation of the tangent will be
y-1 = 1/23 (x-3)
23 (y-1) = x- 3
23y - 23 = x -3
23y - x = 20
25 is the answer

The significant figures are those digits that carry meaning contributing to its precision and includes all digits except: leading and trailing zeros that are placeholders or scales and spurious digits. 546.000 has 3 significant figures.
Since this is an isosceles triangle, angle 66 is also on the left side. So you have 66+66+x=180
132+x=180
x=48
