Solving systems of equations has been used consistently throughout this course in order to shed light on all kinds of different

situations, i.e. finding the intersection point of a system of linear equations, finding eigenvectors, etc. List at least two different types of problems that require solving a system of linear equations, explain how solving a system of linear equations is used, and what information can be learned from the solution.

Answer:

Types of problems that require solving a system of linear equations are:

Calculation of mileage rate

Calculations of ages of children born to a family

Calculation of income over a range of period.

Step-by-step explanation:

Solving a system of linear equations have many real life applications. Many real life problems can be used to set up a system of linear equations.

The following are the steps:

Understand the problem

Break the problem down into parts and represent each part with unknown variables such as: X1, X2, X3,...

Combine the unknown variables mathematically, from the statements of the problem(That is, 2X1 + X2 - 6X3, X1 + 2X2 + 4X3,....)

The results of the solved linear equation system (after solving) will give the solution to the problem. The solutions to the real life problems can be learned by the nature, analysis, and relationship of the solutions of the system of the formed linear equation

Find the values of x:<br><br> I don’t understand how to do this please help
goblinko [34]

Answer:

x = 8

Step-by-step explanation:

11x - 34 and 7x - 2 are vertical angles and congruent, thus

11x - 34 = 7x - 2 ( subtract 7x from both sides )

4x - 34 = - 2 ( add 34 to both sides )

4x = 32 ( divide both sides by 4 )

x = 8

-----------------------

11x - 34 = 11(8) - 34 = 88 - 34 = 54

18y and 11x - 34 are adjacent angles and supplementary , thus

18y + 54 = 180 ( subtract 54 from both sides )

18y = 126 ( divide both sides by 18 )

y = 7

An airplane pilot over the Pacific sights an atoll at an angle of depression of 5 . At this time, the horizontal distance from t
Aleonysh [2.5K]

Answer:

404.98 m

Step-by-step explanation:

The angle of depression is 5°

The horizontal distance from the airplane to the atoll is 4629 meters.

We need to find the height of the plane.

If we consider a triangle. 4629 meters will be the base and angle is 5°. Let h is the height of the plane. Using trigonometry to find it :

\tan\theta=\dfrac{x}{4629 }\\\\\tan(5)=\dfrac{x}{4629 }\\\\x=\tan(5)\times 4629 \\\\x=404.98\ m

So, the height of the plane is 404.98 m.

What % of 60 is 35?
STatiana [176]

Answer:

58.33%

Step-by-step explanation:

  is            %

--------  =  ---------

  of           100

Just plug in the numbers based on what it tells you.

What % = goes in the % spot

of 60 = goes in the of spot

is 35 = goes in the is spot

  35          x

--------- = ---------

  60         100

Cross multiply:

60 * x = 60x        35 * 100 = 3500

60x = 3500

Divide by 60 to get x by itself.

3500 / 60 = 58.33

Put the percent sign after it:

58.33%

I hope this helps.

Determine two pairs of polar coordinates for (3,-3) when 0
Xelga [282]

The two pairs of polar coordinates for the given point (3, -3) with 0° ≤ θ < 360° are (3√2, 135°) and (3√2, 315°).

<h3>What is a polar coordinate?</h3>

A polar coordinate is a two-dimensional coordinate system, wherein each point on a plane is typically determined by a distance (r) from the pole (origin) and an angle (θ) from a reference direction (polar axis).

Next, we would determine the distance (r) and angle (θ) as follows:

r = √(3² + (-3)²)

r = √(9 + 9)

r = 3√2.

θ = tan⁻¹(-3/3)

θ = tan⁻¹(-1)

θ = 3π and 7π/4 (second and fourth quadrants).

Converting to degrees, we have:

θ = 135° and 315°.
