The differential equation M ( x, y )dx N ( x, y )dy 0 is called an EXACT EQUATION if there exist a continuos function F ( x, y ) c (c is a constant) such that F F dF dx dy x y Excellent does not an accident, but it comes through a hard work!! Condition for exact equation: M ( x, y )dx N ( x, y )dy 0 is called an EXACT EQUATION if and only if M N y x Excellent does not an accident, but it comes through a hard work!! GOAL By comparing M ( x, y )dx N ( x, y )dy

multiplying will be used to yield a solution. The extremes of our proportion are 50 and 100 and the means are 2 and x. 50 (100) = 2x 5000 = 2x Both sides are divided by 2 2 2 2 is canceled out on the right side of the equation leaving 5000/2=x, x=2500. This means that the estimated population of bears on the Keweenaw Peninsula is 2500. I have seen on many animal shows on televisions where scientist tag animals release them And come back at a later time and recapture

Differentiate between the two types of change agents and how one or both can be used in this scenario Change agents in the management field are the first order incremental change and the second order discontinuous change. First order incremental change is anticipatory in its tuning and development and at times paradoxically. First order incremental is a continuous change that may incur acclimation to edifices and proceedings. Second order discontinuous change is fast change that is radical and

1 Reflection Reflection is an everyday process. We reflect on a range of everyday problems and situations all the time: What went well? What didn’t? Why? How do I feel about it? We don’t usually follow a formula for this, it just happens as feelings, thoughts and emotions about something gradually ‘surface’. We might choose to do something differently, or not, as a result of reflecting, but reflection is essentially a kind of loose processing of thoughts and feelings about an incident

Linear Functions Unit Plan Part 2 Mr. Dunnas decides to change the graphing linear equations lesson into a problem-based lesson. This lesson is comprised of three components. Component number one is to write the equation in slope-intercept form (solve for y). Component number two is to find solutions (points) to graph via t-tables and slope-intercept form. Component number three is to graph the equation (connect the points that form a straight line). In mastering this lesson, all components

Single Replacement Reactions a. For every reaction that took place you must write the balanced chemical equation b. Which metal reacted the most? c. Rank your metals from more to least active Part II: Double replacement Reactions a. For every reaction where you observed precipitate, write the complete balanced molecular equation, the complete ionic equation and the net ionic equation; use the solubility rules to identify the precipitate and the states of matter of each substance participating

of association between two variables the (X,Y) it also describes correlation that reflects mutual relations of r of 1.0 (positive or negative) indicates an perfect linear relation, while 0 indicates that neither X or Y can be predicted by a linear equation. In these types of cases when the r is positive then there is an increase in both X and Y. Now if the r is negative it’s an increase in just the X and a decrease in the Y. Another method that is commonly used is the dichotomous variable also knows
