You're on a roll — here are the solutions to the questions from the image. Question 5 c) Step 1: Write the equation of the parabola and its derivative. The parabola is given by x^2 = 4ay. Differentiating with respect to x: 2x = 4a (dy)/(dx) (dy)/(dx) = (2x)/(4a) = (x)/(2a) This is the slope of the tangent at any point (x_1, y_1) on the parabola. Step 2: Find the slope of the normal and its equation. The slope of the normal at (x_1, y_1) is m_N = -(1)/(dy)dx|_(x_1, y_1) = -(2a)/(x_1). The equation of the normal at (x_1, y_1) is y - y_1 = m_N (x - x_1). y - y_1 = -(2a)/(x_1) (x - x_1) x_1(y - y_1) = -2a(x - x_1) x_1 y - x_1 y_1 = -2ax + 2ax_1 2ax + x_1 y - (x_1 y_1 + 2ax_1) = 0 Since $(x_1, y_1
