Questions 85 & 86

See attachment.

Question 85

L = x-coordinate - function value of x

L = 2 - cuberoot{2y}

I can also express answer as a fractional power of x.

L = 2 - (2y)^(1/3)

Question 86

L = x-coordinate - function value of x

L = (1/2) - (2/y)

I can also express the answer as a single algebraic fraction.

L = (y - 4)/(2y)

You say?

correct

This set of problems is preparedness for Calculus 1.
Yes? I see the integral symbol in the upper left hand corner of picture.

 

[MathLover1]

the integral symbol means, integration is used to find the area of that figure made by curve, vertical and horizontal line (colored in blue)

Well, I am far away from integration. Don't get me wrong. I can do basic Calculus 1 Integration but nothing beyond that.
