print(16 * 5 / 4 * 2 / 5 - 8)
-3.33
0.0
The given expression evaluates step by step according to the precedence of arithmetic operators (division and multiplication from left to right, followed by subtraction):
\[ 16 \times 5 = 80, \quad 80 \div 4 = 20, \quad 20 \times 2 = 40, \quad 40 \div 5 = 8, \quad 8 - 8 = 0.0. \]
Therefore, the output of the statement is \( 0.0 \).
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
