This article delves into the meaning of the expression h(40) = 1820 within the context of a problem involving hours of training and monthly pay. We'll explore how this mathematical notation relates to the provided data, which shows a clear correlation between the amount of training an individual receives and their corresponding monthly salary. By carefully analyzing the given table and understanding the function h, we can fully grasp the significance of h(40) = 1820.

Analyzing the Data: Hours of Training vs. Monthly Pay

Before diving into the specific meaning of h(40) = 1820, it's crucial to examine the data we have at hand. The table presents a relationship between the hours of training an employee receives and their resulting monthly pay. Let's break down the information:

Hours of Training Monthly Pay
10 1220
20 1420
30 1620
40 1820

From the table, we can observe a consistent pattern: for every 10-hour increase in training, the monthly pay increases by $200. This suggests a linear relationship between the two variables. In mathematical terms, we can represent this relationship using a function. Let's denote the function as h, where the input is the hours of training and the output is the monthly pay. Therefore, h(x) represents the monthly pay for x hours of training. Understanding this functional representation is key to interpreting h(40) = 1820.

Identifying the Linear Relationship

To further clarify the relationship, we can express it as a linear equation. The general form of a linear equation is y = mx + b, where y is the dependent variable (monthly pay in our case), x is the independent variable (hours of training), m is the slope (the rate of change in monthly pay per hour of training), and b is the y-intercept (the monthly pay when there are zero hours of training). From the data, we can calculate the slope (m) by finding the change in monthly pay divided by the change in training hours. For example, using the first two data points (10 hours, $1220) and (20 hours, $1420):

m = ($1420 - $1220) / (20 hours - 10 hours) = $200 / 10 hours = $20/hour

This confirms our earlier observation that the monthly pay increases by $20 for every additional hour of training. Now, we need to find the y-intercept (b). We can use any point from the table and the slope we just calculated. Let's use the point (10 hours, $1220):

$1220 = ($20/hour) * (10 hours) + b $1220 = $200 + b b = $1020

Therefore, the linear equation representing the relationship between hours of training (x) and monthly pay (h(x)) is:

h(x) = 20x + 1020

This equation provides a mathematical model for understanding how training hours influence monthly income based on the provided data. It's important to remember that this model is based on the limited data set we have and might not perfectly predict monthly pay for all training durations. However, it offers a valuable framework for interpretation.

Deciphering h(40) = 1820: A Detailed Explanation

Now that we have a solid understanding of the data and the linear relationship it represents, we can directly address the meaning of h(40) = 1820. In the context of the problem, this equation signifies a specific point on the graph of the function h(x). Let's break it down step-by-step:

  • h: As we established earlier, h represents a function. A function is a mathematical relationship that maps each input value to a unique output value. In this case, the function h takes the number of training hours as input and produces the corresponding monthly pay as output.
  • (40): The number 40 inside the parentheses is the input to the function h. This represents the number of training hours. So, we are considering the scenario where an individual receives 40 hours of training.
  • = 1820: The equal sign and the number 1820 tell us the output of the function h when the input is 40. This output represents the monthly pay. Therefore, 1820 signifies the monthly pay amount.

Putting it all together, h(40) = 1820 means that if an individual receives 40 hours of training, their monthly pay will be $1820. This is a direct interpretation based on the function h and the provided data. We can verify this by plugging 40 into the linear equation we derived earlier:

h(40) = 20 * 40 + 1020 h(40) = 800 + 1020 h(40) = 1820

This confirms that our interpretation aligns with the mathematical model we created from the data. Understanding this notation is crucial for interpreting mathematical relationships in real-world scenarios.

Connecting to the Table Data

Furthermore, h(40) = 1820 is explicitly stated in the table provided. The table directly shows that when the hours of training are 40, the monthly pay is $1820. This reinforces the meaning of the equation and highlights the connection between the mathematical notation and the practical data representation. In essence, h(40) = 1820 is a concise way to express a specific piece of information contained within the table.

Implications and Predictions

Understanding h(40) = 1820 also allows us to make predictions based on the observed relationship. For example, if we wanted to know the monthly pay for 50 hours of training, we could use the function h(x): h(50) = 20 * 50 + 1020 = 2020. This suggests that an individual with 50 hours of training might earn $2020 per month, assuming the linear relationship continues to hold. However, it's important to remember that these predictions are based on the existing data and might not be perfectly accurate for values outside the range provided in the table. Nevertheless, h(40) = 1820 serves as a crucial anchor point for understanding and extrapolating the relationship between training hours and monthly pay.

In Conclusion: The Significance of h(40) = 1820

In summary, h(40) = 1820 within the context of this problem means that an individual who receives 40 hours of training is expected to earn $1820 per month. This interpretation is derived from the given data, which demonstrates a linear relationship between training hours and monthly pay. The function h(x) represents this relationship mathematically, and h(40) = 1820 is a specific instance of this function. Understanding this notation is essential for interpreting mathematical models and applying them to real-world scenarios. By analyzing the data, deriving the linear equation, and deciphering the meaning of h(40) = 1820, we have gained a comprehensive understanding of the relationship between training and compensation in this particular problem. This type of analysis can be applied to various situations where a correlation exists between two or more variables, allowing for informed decision-making and accurate predictions. The ability to interpret function notation like h(40) = 1820 is a fundamental skill in mathematics and its applications.
