Solution Steps

Step 1: Identify two points on the line

From the graph, identify two points that the line passes through. For example, let's use the points (0, 2) and (4, -1).

Step 2: Calculate the slope (m)

Use the slope formula \( m = \frac{y_2 - y_1}{x_2 - x_1} \): \[ m = \frac{-1 - 2}{4 - 0} = \frac{-3}{4} = -\frac{3}{4} \]

Step 3: Use the slope-intercept form (y = mx + b)

The slope-intercept form of a line is \( y = mx + b \). We already have the slope \( m = -\frac{3}{4} \) and one point (0, 2), which is the y-intercept \( b \).

Final Answer

The equation of the line is: \[ y = -\frac{3}{4}x + 2 \]

This chemical reaction is exothermic. High temperatures are usually not ideal for exothermic reactions. Look closely at the chemical reaction equation. Why do you think high temperatures are used in the Haber Process? What does increasing the temperature do to the reactant particles that would result in a higher product yield?

Suppose a company incurred 1 million in expenses related to the restructuring of its business. These expenses related to store closings and severance pay for terminated employees. Because the restructuring is going to cause the company to have a "bad year," the CFO would like to make it a "really bad year." The CFO encourages the chief accountant to over-estimate certain expenses and charges. The CFO explains, "If we take the extra charges this year, then we don't have to report those charges in future years." Required: 1. Understand the reporting effect: If the chief accountant follows the CFO's request, how will net income be affected in the current year? How will it be affected in future years? 2. Specify the options: If the chief accountant does not follow the CFO's request, how is the balance of retained earnings affected in the current year? 3. Identify the impact: Are investors and creditors potentially harmed by the CFO's suggestion? 4. Make a decision: Should the chief accountant follow the advice of the CFO? 1. Net income will be in the current year and in future years. 2. The balance of retained earnings will be in the current year. 3. Are investors and creditors potentially harmed by the CFO's suggestion? 4. Should the chief accountant follow the advice of the CFO?

The value of a machine, V, at the end of t years is given by V=C(1-r)^t, where C is the original cost and r is the rate of depreciation. Find the value of a machine at the end of 4 years if the original cost was 2040 and r=0.1. Round to the nearest cent.
