Understanding the Function
First things first, let's make sure we understand what the function h(x) = (1/9)(90 - x) actually means. In math, a function is like a machine. You put a number in (that's the 'x'), and the function does something to it and spits out another number (that's the 'h(x)'). In our case, the function h takes the input x, subtracts it from 90, and then divides the result by 9. So, when we see h(45), we're being asked to find the output of the function h when the input is 45. The function, in essence, outlines a specific set of operations we need to perform on any given input value x to determine its corresponding output. This concept is core to grasping various mathematical concepts, making it essential to understand the basic mechanics of how functions operate. This foundational understanding simplifies the process of problem-solving. By familiarizing yourself with the function, you become better at recognizing and implementing the correct mathematical operations. Now, let's replace x with 45 in our function. This substitution is the cornerstone of function evaluation, enabling us to pinpoint the value of h(45). So, let's get started. By doing this, we're simply plugging in a specific value to see what comes out. It's like a math substitution. Ready? Here we go!
Step-by-Step Calculation of h(45)
Alright, let's get down to business and calculate h(45) step by step. This is where the magic happens! We'll carefully replace every x in our function with the number 45 and then perform the calculations. Remember, the function is h(x) = (1/9)(90 - x). Let's start by substituting 45 for x: h(45) = (1/9)(90 - 45). The first step involves subtracting 45 from 90. So, 90 - 45 = 45. Now, our equation looks like this: h(45) = (1/9)(45). Next, we multiply 45 by (1/9). Remember that multiplying by (1/9) is the same as dividing by 9. So, we're essentially doing 45 / 9. And what's 45 divided by 9? It's 5! Therefore, h(45) = 5. It is a crucial step in the solution. You see, function evaluation problems often seem complex at first glance. However, by breaking them down into simpler, sequential steps, you can avoid any confusion. Remember, the secret is to take it one step at a time! Keep in mind the order of operations (PEMDAS/BODMAS) to ensure you perform the operations in the correct sequence. Mastering these steps will greatly enhance your ability to confidently solve similar mathematical problems. The meticulous step-by-step approach not only ensures accuracy but also reinforces the underlying principles of function evaluation. This strategy is also useful in real-world scenarios. Think of it as a recipe. Each step builds upon the previous one, leading to a specific result. By following this method, even complicated math problems become manageable.
The Answer and Explanation
So, after all that calculation, we've found that h(45) = 5. Looking back at our answer choices, we see that none of them match. It looks like there might have been a bit of a hiccup with the options provided! However, our calculation is correct. We methodically followed the steps to determine the value of the function at a specific point. Our goal was to evaluate h(45). We did this by substituting 45 for x in the function and then simplifying. The key takeaway here is not just the final answer, but the process. You've now successfully evaluated a function at a specific point. This skill is critical in various mathematical contexts. You're now equipped to solve similar problems. Always remember to break down the problem. Take it one step at a time, and you'll be well on your way to math mastery! Therefore, even if the provided answer choices do not contain our calculated value, it doesn't diminish the fact that we have correctly computed the result. The correct application of the function's rules is what truly matters. In essence, the value h(45) = 5 showcases our proficiency. This also demonstrates a strong grasp of function evaluation. This method of breaking down the problem is applicable across a variety of mathematical concepts. Remember this when tackling any future function evaluation problems, you'll be well-prepared to tackle them. Keep practicing, and you'll become more confident in your abilities!
