As far as our arithmetic problem is concerned, the calculation formula of profit rate should follow the first one, which is actually: profit rate cost × 100%= profit rate. Our formula for calculating profit rate does not need to consider other things, including a series of costs such as cost or marketing, so this is a simple calculation method.
The key to profit rate refers to the ratio of a surplus value to all prepaid capital, but this profit rate is calculated through the conversion of a surplus value rate, which is another ratio calculated by different types of the same surplus value, but this ratio is the ratio of profit to cost.
At work, people often think that profit rate is the ratio of surplus value and profit to the total capital of the same advance payment, and it is a level of capital gain. But the explanation of this profit rate is the analysis of the company's profit, usually the analysis of the market sales profit and cost profit, its annual output profit rate and capital profit rate, but for everyone's math class, it is not necessary to use such a complicated calculation method.
Find the tangent equation: k=2x-2=-2. Geometrically, a broken line refers to a parallel line that just touches a certain point on the graph. Most accurately, when a polyline passes through a certain point in a graph (i.e. tangency), the direction of the polyline is the same as that of the main point on the graph. In solid geometry, parallel lines that have only one common intersection with a circle are called the tangents of the circle. An equation refers to an equation containing an unknown quantity. It is a formula that expresses the equal relationship between two mathematical formulas (such as two numbers, function formula, quantity and calculation), and the unknown quantity that makes the equation established is called "solution" or "root". A process of finding the solution of an equation is called "column equation".
