Chapter 8: Problem 67

Verify your solutions to any five exercises from Exercises \(1-42\) by using a graphing utility to graph the two equations in the system in the same viewing rectangle. Then use the intersection feature to verify the solutions.

Short Answer

Expert verified
The solution will depend on the chosen exercises and the outcome from the graphing utility. However, the intersection points of the graphed equations will verify the solutions to those equations.

Step by step solution

01

- Choose the equations

Choose any five pairs of equations from the exercises 1-42. For instance, let's take two simple equations, \(y = 2x + 1\) and \(y = -x + 3\).
02

- Plot the equations

Input the equations into the graphing utility. Generally, there would be an option to enter the equation and then plot it. Do the same for both the equations. Ensure that both graphs are visible in the same viewing rectangle.
03

- Identify the intersection

After the graphs are plotted, visualize and identify where the two graphs intersect. Most graphing utilities will have a 'Intersection' tool or feature that will allow you to precisely find and mark these points.
04

- Verifying the solution

The intersection point of the two graphs represents the solution to the system of equations. Cross-check the coordinates of the intersection with the solution of the equations. The intersection point should satisfy both the equations.

Suppose that \(\sin \alpha=\frac{3}{5}\) and \(\cos \beta=-\frac{12}{13}\) for quadrant II angles \(\alpha\) and \(\beta .\) Find the exact value of each of the following: a. \(\cos \alpha\) b. \(\sin \beta\) c. \(\cos (\alpha+\beta)\) d. \(\sin (\alpha+\beta)\) (Section \(6.2, \text { Example } 5)\)

The table shows the price of a gallon of unleaded premium gasoline. For each price, the table lists the number of gallons per day that a gas station sells and the number of gallons per day that can be supplied. $$\begin{array}{lll}{\text { Price per }} & {\text { Gallons Demanded }} & {\text { Gallons Supplied }} \\ {\text { Gallon }} & {\text { per Day }} & {\text { per Day }} \\ {\$ 3.20} & {1400} & {200} \\ {\$ 3.60} & {1200} & {600} \\ {\$ 4.40} & {800} & {1400} \\ {\$ 4.80} & {600} & {1800}\end{array}$$ The data in the table are described by the following demand and supply models: Demand Model \(\quad\) Supply Model \(p=-0.002 x+6 \quad p=0.001 x+3\) a. Solve the system and find the equilibrium quantity and the equilibrium price for a gallon of unleaded premium gasoline. b. Use your answer from part (a) to complete this statement: If unleaded premium gasoline is sold for _____ per gallon, there will be a demand for ______ gallons per day and ______ gallons will be supplied per day.

An objective function and a system of linear inequalities representing constraints are given. a. Graph the system of inequalities representing the constraints. b. Find the value of the objective function at each corner of the graphed region. c. Use the values in part (b) to determine the maximum value of the objective function and the values of \(x\) and \(y\) for which the maximum occurs. Objective Function Constraints $$ \begin{aligned} &z=4 x+2 y\\\ &\left\\{\begin{array}{l} {x \geq 0, y \geq 0} \\ {2 x+3 y \leq 12} \\ {3 x+2 y \leq 12} \\ {x+y \geq 2} \end{array}\right. \end{aligned} $$

determine whether each statement makes sense or does not make sense, and explain your reasoning. Because \((x+3)^{2}\) consists of two factors of \(x+3,1\) set up the following partial fraction decomposition: $$\frac{5 x+2}{(x+3)^{2}}=\frac{A}{x+3}+\frac{B}{x+3}$$

Expand: \(\log _{8}\left(\frac{\sqrt[4]{x}}{64 y^{3}}\right) .\) (Section 4.3, Example 4)
