The value of f(2a) is 8a
<h3>What is a function?</h3>
A function can be defined as a rule or expression that shows the relationship between a dependent and independent variable.
From the information given, we have;
g(a) = 4a
Let's determine the value for f(2a)
a = 2a
Let's substitute the value of a as 2a in the function
g(a) = 4a
g(2a) = 4 ( 2a)
Multiply through
g(2a) = 8a
Thus, the value of f(2a) is 8a

The percentage of lemon in the juice is 10%
The percentage of water sugar is (100-10)=90%
The quantity of lemon in 20 liters of sugar water will be:
amount=(percentage of lemon)/(percentage of sugar water)×(amount of sugar water)
=10/90×20
=2 2/9 liters
Answer: 
Step-by-step explanation:
1. By definition, two slopes are perpendicular if their slopes are negative reciprocals of each other. So, let's find the slope of the other line.
2. The equation given in the problem is written in Point-slope form:
Where m is the slope.
3. Therefore, the slope of its perpendicular line must be:
4. You have the point (-5,7), so you can substitute it into the point-slope formula to find the equation of the new line:
5. In slope intercept form is:
