Fig. 1: Graph of the linear equation y=3x+4 The rate of change is the slope of the linear function. To find the slope we have two points: (x1,y1) and (x2,y2) where all values are real. The rate of change between two points is given by this formula. Average rate of change=...
Suppose an electrical circuit contains a variable resistor. As the resistor is adjusted from 3 ohms to 3.15 ohms, the electrical current is decreasing by an average 0.03 amps per ohm. Write an equation that expresses this situation in terms of an average rate of change. ...
This is the manual way. It is not tough, but getting a very close value from this method will take time. You can also try this method on paper, but it might take a whole day to find the internal rate of return for some future cash flows. Method 4 – Applying the Goal Seek Feature...
or individual to meet their financial obligations. For example, too much debt can be dangerous for a company and its investors. However, if a company’s operations can generate a higher rate of return than the interest rate on its loans, then the debt may help to fuel growth. ...
The information from your credit report is used to determine your credit score. Credit scoring companies assign values to the information in your credit report and then use a complex equation to compute your credit score. Some of those values include: Whether you pay your bills on time If yo...
Find the Difference Quotient: Polynomial Function Letf(x)=2x2−x, evaluate the difference quotient. Step 1:f(x+h): Plug in x+h for all x-variables. f(x+h)=2(x+h)2−(x+h) Simplify by finding(x+h)2and replacing it in the equation. ...
The derivative of a function gives the instantaneous rate of change for a given point. Think of the way the velocity of a car is always changing as it accelerates and decelerates. Although you can calculate the average velocity for the entire trip, somet
You can find the compounded interest rate given an annual interest rate and a dollar amount. The EFFECT worksheet function uses the following formula: =EFFECT(EFFECT(k,m)*n,n) To use the general equation to return the compounded interest rate, use the foll...
Rate Law Equation: rate=k[A]x[B]y rate:rate is the rate of the reaction in moles per liter per second. [A] and [B]:[A] and [B] are the concentrations of the reactants in the reaction. x:x is the reaction order with respect to reactant A. ...
There are many ways to increase response rates, but customers find some of the most common methods irritating. This comprehensive guide will get you more feedback by teaching you how to increase the response rates to your customer satisfaction surveys in a customer-friendly way. Everyone who star...
