THIS IS MY HOME WORK PLZZ ANSWER ANY NUMBER YOU KNOW. IF YOU CANT SEE THE QUESTION JUST PRESS CONTROL + to zoom it . If you answer it please indicate the number you answer tnxxx. T__T need it badly.


If you need it badly you had better get busy and do the work. It is against the PF rules for us to do your take-home quiz questions for you.

1. What is the difference between maxima and minima?

Maxima and minima are both terms used in calculus to describe the highest and lowest points, respectively, on a graph. The main difference between them is that a maxima is the highest point on a graph, while a minima is the lowest point. In other words, a maxima is the peak of a curve, while a minima is the bottom of a curve.

2. How do you find the maxima or minima of a function?

To find the maxima or minima of a function, you can use a process called optimization. This involves taking the derivative of the function and setting it equal to zero. Then, solve for the variable to find the critical points. Next, plug these critical points into the original function to determine which one results in the highest or lowest value. That point will be the maxima or minima.

3. What are related rates?

Related rates refer to the concept of finding the rate of change of one variable with respect to another variable. In other words, it involves finding how two different quantities are related to each other and how they are changing over time. Related rates problems often involve the use of derivatives to solve.

4. How do you solve related rates problems?

To solve related rates problems, you will first need to identify the two variables that are changing and how they are related. Then, you will need to find the derivatives of each variable with respect to time. Next, plug in the given values and use the chain rule to solve for the unknown rate. Finally, don't forget to include units in your answer.

5. What are some real-life applications of maxima, minima, and related rates?

Maxima, minima, and related rates have many real-life applications in fields such as engineering, physics, and economics. For example, they can be used to maximize profits in a business, optimize the design of a bridge, or determine the maximum velocity of a falling object. Additionally, related rates can be used to model the growth of populations, the spread of diseases, or the cooling of a cup of coffee.
