Answer:

C) 5 sin⁻¹(x − 1) + C

Explanation:

∫ 10 / √(8x − 4x²) dx

Simplify.

∫ 5 / √(2x − x²) dx

Complete the square.

∫ 5 / √(-(x² − 2x) dx

∫ 5 / √(-(x² − 2x + 1 − 1) dx

∫ 5 / √(-(x² − 2x + 1) + 1) dx

∫ 5 / √(-(x − 1)² + 1) dx

∫ 5 / √(1 − (x − 1)²) dx

Integrate using a table.

5 sin⁻¹(x − 1) + C
