Find the equation of the tangent line
5x^2+y^2=14 at (1,3).
P.S: It's calculus.
So far I know this much
10x+2y(dy/dx)=o
10x 10x
___________________
2y(dy/dx)= 10x
(dy/dx)= 10x/2y= 5x/y
m= 5(1)/3= 5/3
y=mx+b
3= 5/3(1)+b then what?

ahh, so close!
solve for b in your last equation
I get b = 14/3
put m and b into your y = mx + b and you are done

i was wondering if anyone could help me on this problem. expand: x^2 (y^2 + 10x) z^3 (5x + 3z^4) First one: x^2 (y^2 + 10x) x^2 is the same thing as 1/x^2. Therefore, we have this: 1/x^2 (y^2 + 10x) Multiply using the distributive …

Consider the function h as defined. Find functions f and g so (f o g)(x)=h(x) h(x)=8/x^2+10 I think it is: h(x)=8/x^2+10 h(x)=8/x^2+10*x^2/x^2 h(x)=8/x^2+10x^2/x^2 h(x)=8+10x^2/x^2 h(x)=10x^2+8/x^2 h(x)=2(5x^2)+2(4)/x^2 h(x)=2(5x^2+4)/x^2

Thanks Reiny, but I'm still lost. I understand how you multipled by 10X on the right to get 17x, but you went too fast on the left, and I have no idea how you got 10x^220 from the starting left side. Can you show each step?
