Please the steps, thank you.

20. Use implicit differentiation to find the equation of the line tangent to the curve at the indicated point. x2/3 + y?/3 = 4 at(-3V3, 1) 21. Use implicit differentiation to find points of the horizontal tangents for the relation. 2(x2 + y2)2 = 25(x2 - y2) 22. Let s(t) = t4 - 4t3 + 2 be a position function. Determine the time t where the acceleration is 0 and the velocity at these times. Differentiate the following functions. 23. f(x) = V5-x2 24. f(x) = (x3 -8)(x2+5)
