To find the area enclosed by the curves, we need to set up an integral. First, let's express both curves in terms of \( y \) and solve for the intersection points. The first curve is \( y = x^2 - 4x + 4 \) (a parabola) and the second curve is \( y^2 = 16 - 8x \), which is a sideways parabola.
Next, we solve for the intersection points by equating the two curves, and then integrate the difference of the two functions to find the enclosed area.
After solving the integration, the area enclosed by the curves is \( \frac{8}{3} \).
If the area of the region $\{ (x, y) : |x - 5| \leq y \leq 4\sqrt{x} \}$ is $A$, then $3A$ is equal to
Two circular discs of radius \(10\) cm each are joined at their centres by a rod, as shown in the figure. The length of the rod is \(30\) cm and its mass is \(600\) g. The mass of each disc is also \(600\) g. If the applied torque between the two discs is \(43\times10^{-7}\) dyne·cm, then the angular acceleration of the system about the given axis \(AB\) is ________ rad s\(^{-2}\).
