<span>From the pythagorean theorem, we know that x^2 and y^2 = 15^2, where x and y, where x is the base moving from the wall and y is the distance of the ladder sliding down. This means that y = sqrt(225 - x^2). Plugging in x = 13 gives us y = 2sqrt(14). Differentiating both sides of the original equations gives us dy/dt = 13 x 4 / 2sqrt(14) = 52/2sqrt(14) = 26/sqrt(14) ft/s.</span>
Hence, the correct answer is: C) (x - 6)^2 = 45
Further explanation:
Given equation is:
We will move the constant term on other side of the equation
To complete the square, we will take the coefficient of x and divide it by 2, as we already know that one term is x.
So, adding (6)^2 on both sides
Hence, the correct answer is: C) (x - 6)^2 = 45
