well, the tell-tale part in the points will be the coordinates, hmmm now, the x-coordinate for both points is the same, well, that simply means is a vertical line.  Check the picture below.

The arc YZ represented in the diagram, its length is :

2π/3 or 4π/6

A circle's arc can be formed by any two points on its circumference.

A circle's arc length (S) = r(θ), where r is the radius and theta is the central angle in radians.

Given WY = XZ = 6,

So YZ = TZ = 3radius

and m∠XY = 140°.

so, m∠YZ = 180° - 140°.  (As a semicircle with a central angle of 180°.)

m∠YZ = 40°.

then,  m∠YZ = (40/180)°×π rad.

m∠YZ = 2π/9 rad.

then, Arc length of YZ =  = 3×(2π/9).

YZ = 6π/9.

YZ = 2π/3  or  4π/6

The equation y = 2x² - 12x + 23 describes the function graph that includes a vertex at (3, 5) and passes through the point (5, 13).

The vertex of a parabolic equation is at the point and the vertex form is y = a(x - h)2 + k, where a, h, and k are constants (h, k).

Find the function whose graph has the vertex at (3, 5) and passes through the point in the question (5, 13).

Assuming it to be a parabolic function, we know that a parabolic equation's vertex form is y = a(x - h)2 + k, where a, h, and k are constants, and the vertex is located at the position (h, k).

As the vertex of the necessary function is at the position (3, 5), we may substitute h = 3 and k = 5 to obtain the following equation in the above equation:

y = a(x - 3)² + 5

Now that we know that the graph passes through the point (5, 13), we can change the original equation to read:

13 = a(5 - 3)² + 5,

or, 13 = 4a + 5,

or, 4a = 13 - 5 = 8,

or, a = 2.

We obtain the following from the equation y = a(x - h)2 + k by inserting a = 2, h = 3, and k = 5:

y = 2(x - 3)² + 5,

alternatively, y = 2(x² - 6x + 9) + 5,

alternatively, y = 2x² - 12x + 18 + 5,

Alternatively, y = 2x² - 12x + 23.

As a result, the function graph with the vertex at (3, 5) and the point of intersection (5, 13) yields the equation y = 2x² - 12x + 23.

Answer: Option A.

Graph A, and graph C could not possibly be density curves for a continuous random variable if they were provided with the right scale.

A symbol (often a letter) used in algebra to represent an unknowable numerical value in an equation. Variables can have a wide range of values, which is why they are called variables. Thus, a variable can be thought of as a quantity that can take on different values depending on the circumstances of a given issue. As the program executes, we may store, modify, and access this data thanks to variables. All types of information can be stored in variables.

Four graphs of different nature as options.

We are required to find a graph that is not a continuous variable.

In mathematics, a continuous function is a function such that a continuous variation of the argument induces a continuous variation of the value of the function.

Continuous lines are those lines that when decreased, decrease with continuity and when increased, increase with continuity.

Given that,

Answer: y = -3x + 6

Step-by-step explanation:

If it is perpendicular to the line -3x + 2, then it's slope should also be -3.

The standard form of a line is y = mx + b. As our slope is -3, we have that our line is y = -3x+b. Now, let's put the given point into the line. x = 3 and y = -3, so -3 = -3*3 + b. Hence, b = -3+9 = 6. The equation of the line is y = -3x + 6.

Answer:

The slope is 1/4 and the y-intercept is 40

t is the temperature.

n is the number of chirps per minute.

Step-by-step explanation:

The unknow angles are as follows:

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.

Therefore,

m∠4 = 72 degrees

Hence,

m∠1 + m∠4 = 180 (angle on a straight line)

m∠1 = 180 - 72

m∠1 = 108 degrees

m∠2 = m∠4 (vertically opposite angles)

Vertical angles are the angles formed when two lines intersect each other. Vertical angles are congruent.

Therefore,

m∠2 = 72 degrees

m∠5 = m∠1 (corresponding angles)

Corresponding angles are angles that occur on the same side of the transversal line and are equal in size.

m∠5 = 108 degrees.

m∠7 = m∠5(vertically opposite angles)

m∠7 = 108 degrees

m∠8 = m∠2 (alternate exterior angles)

Alternate exterior angles are congruent.

m∠8 = 72 degrees

Given:

The car ride from Kiley's house to the airport.

Distance =24.3 miles.

Time =1/2 hour.

We know that

Substitute Distance =24.3 miles and time =1/2 hour to compute the average rate of the car ride from Kiley's house to the airport.

Hence the average rate of the car ride from Kiley's house to the airport is 48.6 miles per hour.

2)

Given that they walked 3/4 hours to the waiting area and covered the distance of 1.2 miles.

Distance =1.2 miles.

Time =3/4 hours.

we know that

Substitute distance =1.2 miles and time =3/4 hours to compute the average rate of the walk from the car to the waiting area by the gate, at the airport.

Multiplying 1.2 and 4, we get 4.8

Dividing 4.8 by 3, we get 1.6

Hence at the airport, the average rate of the walk from the car to the waiting area by the gate is 1.6 miles per hour.

Using an exponential function, it is found that:

a) During the first five days, the population of organism A grew by a factor of 2^5.

b) During the next three days, the population of organism B decayed by a factor 2^(-3).

c) The expression for the total change is of 2².

An exponential function is modeled according to the following rule:

[tex]y = ab^x[/tex]

In which:

For the first five days, the population doubles each day, hence the rate of change is of:

b = 2.

The growth factor will be of:

y = 2^5 = 32

During the next three days, the population cuts in half each day, hence the rate of change is of:

b = 0.5.

Then the decay factor is of:

y = (0.5)³ = (1/2)³ = 2^(-3).

Applying properties of exponents, over the entire period, the change in the population will be of:

2^5 x 2^(-3) = 2^(5 - 3) = 2².

As when we multiply two terms with the same base and different exponents, we keep the bases and add the exponents.

Of these, only 37.42° is a possible value of B (sum of angles of a triangle is 180°).

So, we have that:

[tex] a=229, b=244, A=37.8^{\circ}, B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]

Angles of a triangle add to 180°, so:

[tex]C=180^{\circ}-A-B=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)

[/tex]

Using the Law of Sines again,

[tex]\frac{c}{\sin C}=\frac{a}{\sin A} \\ \\ c=\frac{a \sin C}{\sin A} \\ \\ =\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}}[/tex]

So, there is one possible triangle, where:

Answer:

The second bag (4.75)

Step-by-step explanation:

The number of pennies that Ari has is 14.

The number of nickels that Ari has is 8.

The linear equations that represent this question are:

0.01p + 0.05n = $0.54 equation 1

p + n = 22 equation 2

Where:

In order to determine the number of nickels, multiply equation 2 by 0.01

0.01p + 0.01n = 0.22 equation 3

Subtract equation 3 from equation 1:

0.04n = 0.32

Divide both sides by 0.04
