The variables a and b are,
⇒ a = 3
⇒ b = 4
A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines relationship between one variable and another variable.
We know that;
For a hyperbola ;
⇒ x² / a² - y² / b² = c²
where, a² + b² = c²
And, The directrix is the line, y = a² / c
and, the focus is at (0, c).
Here, We have;
⇒ c = 5,
⇒ a² = 9,
So We get;
⇒ b² = 5² - 9 = 16.
Thus, We get;
⇒ a = √9 = 3
⇒ b = √16 = 4

Manuel gets paid $460 for the first 40 hours of work, and an additional $103.50 for the 6 hours of overtime, making his total weekly pay $563.50 if he works 46 hours per week.
To calculate Manuel's weekly wage based on his hourly rate, we first need to consider his regular work hours and his overtime hours separately.
For his regular work hours, which are the first 40 hours, Manuel is paid at his regular hourly rate of $11.50. Therefore, his earnings for the 40 hours are: 40 hours * $11.50/hour = $460.
If he works more than 40 hours in a week, the additional hours are considered overtime.
For these extra hours, he is paid 1.5 times his regular pay. In this case, Manuel worked 46 hours, so he had 6 hours of overtime. His overtime earnings are: 6 hours * 1.5 * $11.50/hour = $103.50.
Adding these together, in a 46-hour week, Manuel's total earnings would be $460 + $103.50 = $563.50.
