Trigonometry Applications Word Problems

You have been contacting cartographers and land surveyors to explore how they utilize graphs of functions in their work, and have learned that they create formulas to calculate size and mass. 1. A lobster boat is situated due west of a lighthouse. A barge is 12 km south of the lobster boat. From the barge the bearing to the lig ...continues

Solving Systems of Linear Equations

1. Solve to the homogenous system of linear equations. {2x - 2y + z = 0 both equations are in the same { {-2x + y + z = 0 I got the following: x = ¾c, y = -c, z = 1/2c 2. Find the real solutions to the system of equations using the addition method. x^2 + 8y^2 = 5 x^2 – 4y^2 = 2 Is there a real ...continues

Directions of Vectors and Substitution an Elimination Methods for Solving Linear Systems of Equations

How do you explain why vectors QR and RQ are not equivalent? Explain when the elimination method for solving a system of equations is preferable to the substitution method. I need step by step help in solving these problems

Trigonometric Equations
