Answer:

Step-by-step explanation:

The marked angles are all "interior" -- between the parallel lines. Ones on the same side of the transversal (t) are called "same-side" or "consecutive" interior angles. Angles 1 and 4, 2 and 3 are pairs of consecutive interior angles.

Angles on opposite sides of the transversal are called "alternate" interior angles. Pairs 1 and 3, and 2 and 4 are pairs of alternate interior angles.

Alternate interior angles are congruent. Consecutive interior angles are supplementary (as are the angles of any linear pair).

__

1) Angles ∠1 and ∠3 are congruent.

__

2) Using the above fact, we can set the expressions for the angle measures equal to solve for x.

  5x -2 = 2x +55

  5x = 2x +57 . . . . . add 2

  3x = 57 . . . . . . . . . subtract 2x

  x = 19 . . . . . . . . . . divide by 3

__

3) Angle 1 is ...

  ∠1 = 5x -2 = 5(19) -2 = 93

Angle 4 is its supplement.

  ∠4 = 180 -∠1 = 180 -93

  ∠4 = 87 . . . degrees

Answer:

  19.2

Step-by-step explanation:

You want the solution to 38.4 = 2x.

When you divide both sides of the equation by 2, you will have your answer.

  38.4/2 = (2x)/2

  19.2 = x

The solution to the equation is x = 19.2.

Additional comment

When you learned multiplication and division, you learned that each multiplication fact corresponds to two division facts:

  A = B×C . . . . . . . 6 = 2×3

  A/B = C . . . . . . . . 6/2 = 3

  A/C = B . . . . . . . . 6/3 = 2

We use that relationship here to find the value of one of the factors in the product:

  38.4 = 2·x

  38.4/2 = x

The other division fact is still true, but isn't useful here for finding the value of x.

  38.4/x = 2

what are graphs?

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

from the question:

The final behavior of the graph depicted in the image appears to be that the output (y) values approach negative infinity as the input (x) values grow extremely large (near infinity) or extremely small (approach negative infinity). This shows that the graph exhibits a downward trend, diminishing behavior at both ends, and a lower bound of negative infinity rather than an upper bound. As a result, we can state that the graph behaves at its endpoints by approaching negative infinity on both ends.

The simplified expression for the difference in the areas of Circle A and Circle B is = 12π/(x+2)²

The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is \(A = \pi r^2\), where r is the radius of the circle. The unit of area is the square unit, for example, \(m^2, cm^2, in^2\), etc.

We know that :

The formula of circle's circumference is = 2πr

We have :

Circle A has a circumference of \(\frac{8\pi }{x+2}\) units

and Circle B has a circumference \(\frac{4\pi }{x+2}\)

Now, First we calculate the area of circle A is:

8π/x+2 = 2πr

r = 8π/x+2 × 1/2π

r = 4/x+2

Area = πr² = (4/x+2)²π

Now, for circle B

4π/x+2 = 2πr

r = 4π/x+2 × 1/2π

r = 2/2x+2

Area =( 2/2x+2)²π

Simplified expression for the difference in the areas of Circle A and Circle B are:

(4/x+2)²π - ( 2/x+2)²π

= π/(x+2)²( 4²-2²)

= π/(x+2)²(16-4)

= 12π/(x+2)²

The question is incomplete. Here is the complete question.

The following data represents the 2011 guaranteed salaries (in thousands of dollars) of the head coaches of the final 8 teams in the 2011 NCAA Men's Basketball Championship. The data represent the 2011 salaries of basketball coaches of the following universities, entered in that order: Arizona, Butler, Connecticut, Florida, Kansas, Kentucky, North Carolina and Virginia Commonwealth. (Source: www.usatoday.com)

                  1950 434 2300 3575 3376 3800 1655 418

Compute the range, variance and standard deviation for these data.

Round your answers to the nearest integer, where appropriate.

Answer: Range = 3382

              Variance = 1785193

             Standard Deviation = 1336

Step-by-step explanation: Range is the difference between the highest value and lowest value of the set.

Range for the coaches salaries is

range = 3800 - 418

range = 3382

Variance and Standard Deviation are both the statistical measures of the spread between in the data set. In other words, they show how far the numbers in the set are from the mean of the data.

Variance is calculated as

\(s^{2}=\frac{\Sigma (x-\mu)^{2}}{n}\)

x are the numbers in the set

μ is the mean

n is sample or population quantity

For the coaches' salaries, variance is

\(s^{2}=\frac{\Sigma (418-2188.5+...+3800-2188.5)^{2}}{8}\)

s² = 1785192.6

Standard deviation is the squared root of variance:

\(s=\sqrt{s^{2}}\)

Then, for coaches' salaries:

\(s=\sqrt{1785192.6}\)

s = 1336.11

For the 2011 coaches' salaries, range, variance and standard deviation are 3382, 1785193 and 1336, respectively

The vertex of the parabola is (h, k) = (3, -8), The graph in red has vertex (3, -8), thus, the red parabola is correct.

A quadratic function is a polynomial function of the form f(x) = ax² + bx + c, where a, b, and c are constants and a is not equal to 0.

We know that the standard form of the parabola is y=ax²+bx+c. Thus, the vertex form of a parabola is y = a(x-h)² + k, and the vertex is given by (h, k)

here,  y = −(x − (3))² (−8) is already in vertex form.

Then,

h = 3

k = -8

Thus, the vertex of the parabola is (h, k) = (3, -8), The graph in red has vertex (3, -8), thus, the red parabola is correct.

The hours that it would take Nisha to make the gungharoos is 301.5 hours

The equation of the line in the scatter plot is given as

Where x is the number of ghungaroos that Nisha would make

We have to put in the value of x as 64 because the question tells us that She made a total of 64 gungharoos

Hence we would have:

y = 4.75 * 64 - 2.5

The value of x in the secant intersection is 4.

If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.

Therefore, let's find the value of x using the secant intersection theorem as follows;

4(4+x + 2) = 5(5 + x - 1)

4(6 + x) = 5(4 + x)

The value of three subsets is \(n(x_{1})=36, n(x_{2})=9, & n\left(x_3\right)=54\).

A set is a collection of objects or elements, grouped in the curly braces, such as {a, b, c, d}. If a set A is a collection of even number and set B consists of {2,4,6}, then B is said to be a subset of A, denoted by B⊆A and A is the superset of B.

The elements of sets could be anything such as a group of real numbers, variables, constants, whole numbers, etc. It consists of a null set as well.

If set A has {X, Y} and set B has {X, Y, Z}, then A is the subset of B because elements of A are also present in set B.

Let the number of elements in \($x_2$\) be \($x$\), then

\($$\begin{aligned}& n\left(x_1\right)=4 x \\& n\left(x_2\right)=x \\& n\left(x_3\right)=6 x\end{aligned}$$\)

Answer:

Area is increasing

Step-by-step explanation:

Let x be the length of rectangle and y be the width of rectangle

We are given that

x=3 in

dx/dt=1 in/min

y=2 in

dy/dt=-0.5/min

We know that

Area of rectangle,\(A=xy\)

Differentiate w.r.t t

\(\frac{dA}{dt}=y\frac{dx}{dt}+x\frac{dy}{dt}\)

Substitute the values

\(\frac{dA}{dt}=2(1)+3(-0.5)=2-1.5=0.5 in^2/min\)

Hence, the area  of rectangle is increasing.

To find the distance between Basti and Cian, we can use the law of sines in triangle ABC. The law of sines states that the ratio of the length of a side to the sine of the opposite angle is constant for all sides and their corresponding angles in a triangle.

Let's label the distance between Basti and Cian as "x". We know that the measure of angle ABC is 50 degrees and the measure of angle BAC is 60 degrees. We also know that Ali is exactly 150 ft away from Basti.

Using the law of sines, we can set up the following equation:

sin(50°) / 150 = sin(60°) / x

To solve for "x", we can rearrange the equation:

x = (150 * sin(60°)) / sin(50°)

Using a calculator, we can evaluate the expression:

x ≈ (150 * 0.866) / 0.766

x ≈ 168.4 ft

Therefore, the distance between Basti and Cian is approximately 168.4 ft.

Answer:

x = 20

Step-by-step explanation:

using the cosine ratio in the right triangle and the exact value

cos45° = \(\frac{\sqrt{2} }{2}\) , then

cos45° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{10\sqrt{2} }{x}\) = \(\frac{\sqrt{2} }{2}\) ( cross- multiply )

x × \(\sqrt{2}\) = 20\(\sqrt{2}\) ( divide both sides by \(\sqrt{2}\) )
