You can solve this equation using the Python square root function: Python >>>a=27>>>b=39>>>math.sqrt(a**2+b**2)47.43416490252569 So, Nadal must run about 47.4 feet (14.5 meters) in order to reach the ball and save the point. ...
1. The value will be 14, the result of 2 * 7, because the parentheses force the addition to happen before the multiplication. 2. The value will be 10, the result of 6 + 4. Python’s operator precedence rules are applied in the absence of parentheses, and multiplication has higher prec...

Raising a number to the power of 0.5 is the same as taking the square root, but notice that even though the square root of 9 is an integer, Python returns the float 3.0.For positive operands, the ** operator returns an int if both operands are integers and a float if any one of ...
