The solutions that @tywebb has provided a link to contain at least two mistakes...

Q14 should be y = 6x + 1 rather than y = 54x + 1 (the solution uses m = 54 at x = 1 as the gradient of the tangent, but the point of interest was (0, 1) and so they should have found that m = 6 at x = 0).

Q20 should have three solutions rather than two, the solution at theta = 360 degrees has been missed.

Also, the scale used in drawing the sketch in Q30 is awful, the height of the maximum above the x-axis should be about 30 times the size of the height of the minimum below the x-axis.

Thanks for the additional info
