Answer:
double a;
double b;
double distance = Math.sqrt( (Math.pow(a, 2) + Math.pow(b, 2));
System.out.println("The distance is: " + distance);
Explanation:
The code snippet is written in Java.
First, variable a is declared as a type of double and variable b is also declared as a type of double.
The given formula for the distance is:
√(a² + b²)
So we use the inbuilt function of Java to calculate the power and the square root.
Math.sqrt is to find the square root and it returns a value of type double.
Math.pow is use to calculate the value of a² and b².
a² = Math.pow(a, 2)
b² = Math.pow(b, 2)
Then Math.sqrt is applied to the sum of Math.pow(a, 2) and Math.pow(b, 2), the value is assigned to distance of type double.
The value of distance is now displayed to the user:
System.out.println("The distance is: " + distance);
I'm not sure but exercise?
Answer:
Option D, might fall, but we cannot know without more information
Explanation:
Complete question
If real GDP falls by 2% while work hours fall by 10%, then labor productivity:
a. falls
b. is unchanged
c. rises
d. might fall, but we cannot know without more information
Solution -
As we know
Productivity is equal to Real GDP/ Total Hours Worked. This means that if working hours of the labor force reduces then the productivity will rise.
Here GDP also falls but compared to the total working hours the fall of GDP is 1/5. Hence, the productivity might fall/rise as compared to the case when neither the GDP nor the working hours were falling.
Hence, option D is correct
