Answer:

The value of the constant in the equation below is 20.

Step-by-step explanation:

You are given the formula height = constant/width. All you have to do is take one of the points given on the graph and plug it in to the formula.

Example:

1 = Constant/20

Constant = 20

As per linear equation, the Constant in the given graph is 20.

A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.

Here, Height = Constant/Width

Therefore, Constant = Height × Width

We can take any two random points given on the graph.

Two points are (5, 4) and (20, 1).

For the first point,

Height = 4, Width = 5.

Therefore, Constant = 4 × 5 = 20

For the second point,

Height = 1, Width = 20.

Therefore, Constant = 1 × 20 = 20

Therefore, Constant in the given graph is 20.

Answer:

Solution given:

x=2

y=3

The requried solution to the pair of equations is (2, 3).

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,

Part A: To solve the pair of equations graphically, we need to plot both equations on the same coordinate plane. To plot each equation, we can use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

For the equation y = 2x - 1, the slope is 2 and the y-intercept is -1. For the equation y = 4x - 5, the slope is 4 and the y-intercept is -5. We can plot these two lines on the same coordinate plane and find their intersection point.

Part B: We can find this point by setting the two equations equal to each other and solving for x:

2x - 1 = 4x - 5

Subtracting 2x from both sides, we get:

-1 = 2x - 5

Adding 5 to both sides, we get:

4 = 2x

Dividing by 2, we get:

x = 2

Now that we have found the value of x, we can substitute it into either equation to find the value of y. Using the equation y = 2x - 1, we get:

y = 2(2) - 1

y = 3

Therefore, the solution to the pair of equations is (2, 3).

Answer:

using Pythagoras theorem x=32.7

Answer:

21.7

Step-by-step explanation:

In order to solve this problem, we can use trig functions. We are given the side adjacent to the 37° given and we are looking for the hypotenuse. This means that cosine function is the most suitable. Cosine is written as:

cos(θ°) = adjacent / hypotenuse

We can substitute the values we have:

cos(37°) = 17.3 / x

And rewrite the expression:

x = 17.3 / cos(37°)

Then, use a calculator to evaluate:

x = 21.66194689

This can be rounded to 21.7

Answer: x = -3

Step-by-step explanation:

Focus on triangle QAC. We're given that CQ = CA, which in turn means the angles opposite these sides (angles A and Q in that order) are congruent. This is one property of isosceles triangles. Let's make x equal to each of these angles.

With inscribed angle QAC = x, it doubles to 2x which is the measure of minor arc BC (inscribed angle theorem). Minor arc AB is also 2x, since we're told these two arcs have the same measure.

If minor arc BC = 2x, then cutting this in half leads to x again, which points to inscribed angle BDC equal to x. Notice how inscribed angles QAC and BDC subtend the same minor arc BC. Through similar logic, inscribed angle BDA is also x.

In short: angle BDC = angle BDA = x. This leads to angle ADC = 2x. We'll use this later.

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

Let's go back to triangle QAC. The angles A and Q are both x each. The missing angle C is...

Q+A+C = 180

x+x+C = 180

2x+C = 180

C = 180-2x

Making angle QCA equal to 180-2x

Angle ACD is supplementary to this.

So,

angle ACD = 180-(angle QCA) = 180-(180-2x) = 2x. We'll use this later as well.

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

The first section concluded with angle ADC = 2x, while the second section concluded with angle ACD = 2x

For triangle ACD, the bottom angles C and D are both 2x. This is sufficient evidence to show that triangle ACD is isosceles. Furthermore, it means AC = AD, which are the sides opposite angles D and C respectively.

Answer: :(−7−√132,0),(−7+√132,0)

The mean absolute deviation of the number of points scored is 4.4.

The mean deviation is used to calculate how far the values fall from the mean of the data set.

Here, Given data is 31, 20, 27, 19, 28

Mean = Sum of all data / number of terms

         = (31 + 20 + 27 + 19 + 28)/5

         = 125/5

         = 25

Then, the deviation will be 6, 5, 2, 6, 3

Mean Deviation = Sum of Deviation / Total number of deviation

                          = ( 6 + 5 + 2 + 6 + 3) / 5

                          = 22 / 5

                          = 4.4

Thus, the mean absolute deviation of the number of points scored is 4.4.

Answer:

y is 107° and z is 36°

Step-by-step explanation:

73° and y are supplementary angles so they add up to 180°

Answer:

y = 107

z = 36

Step-by-step explanation:

We are given that line o is parallel to line m, and we can notice line k is a transversal through them both. Using same side interior angles, we can say that:

y + 73 = 180

and

y = 107

Next, using vertical angles, we can say that:

5z - 73 = y

We already have y = 107, so we can substitute that in:

5z - 73 = 107

5z = 180

z = 36

Answer:

The probability that the person uses exactly one of the facilities is 69.23%.

Step-by-step explanation:

Since there are 130 people in a sport center, of which 65 people use the gym, 51 people use the swimming pool, 44 people use the track, 15 people use the gym and the pool, 14 people use the pool and the track. , 10 people use the gym and the track and 1 person uses all three facilities, to determine, if a person is selected at random, what is the probability that the person uses exactly one of the facilities, the following calculation must be performed:

130 = 100

130 - 1 - 15 - 14 - 10 = X

130 = 100

90 = X

90 x 100/130 = X

9,000 / 130 = X

69.23 = X

Therefore, if a person is selected at random, the probability that the person uses exactly one of the facilities is 69.23%.

Answer:

[tex]\theta=71.07^{\circ}[/tex]

Step-by-step explanation:

The given vector is :

v = -12i - 35j

We need to find the angle direction of v.

The general vector is given by :

v = xi+yj

The direction angle is :

[tex]\theta=\tan^{-1}(\dfrac{y}{x})[/tex]

We have, x = -12 and y = -35

So,

[tex]\theta=\tan^{-1}(\dfrac{-35}{-12})\\\\\theta=71.07^{\circ}[/tex]

So, the required direction angle is [tex]71.07^{\circ}[/tex].
