To find the area of the region bounded by the curves \( y = \sqrt{x} \), \( y = 18 - x^2 \), and the \( x \)-axis in the first quadrant, we first need to determine the points of intersection of the two curves. Setting \( \sqrt{x} = 18 - x^2 \), we square both sides to eliminate the square root: \[ x = (18 - x^2)^2 \] Now, rearranging terms and solving this equation will yield the x-values of the intersection points. However, it's easier to graph both functions to identify where they intersect. Once we find the intersection points, we can set up the integral to find the area. The area \( A \) can be expressed as: \[ A = \int_{a}^{b} \left( (18 - x^2) - \sqrt{x} \right) \, dx \] where \( a \) and \( b \) are the intersection points we found. This integral will give us the area between the curves above the x-axis in the first quadrant. After evaluating the integral, we can get the specific numerical value for the area of the region.
