Name a median for ABC.

Name A Median For ABC.

Answers

Answer 1

In the triangle ABC the line segment bisecting AC is the median, i.e. BD.

What are triangles?

Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.

The triangle ABC is given.

In Δ ABC, the line segment AC is bisected, so -

AD = CD

The line segment from a vertex to the middle of the other side is what is meant by a median. When the vertex is an angle in an equilateral triangle or the non-congruent angle of an isosceles triangle, it is also an angle bisector.

Since line segment BD bisects AC.

Therefore, the median is BD.

Answers

Answer:

h - 3

See explanation below

Step-by-step explanation:

This is not too difficult

We have (- 2h + 1) + (3h - 4) and we are asked to simplify

Expand the brackets:
(- 2h + 1) = - 2h + 1

(3h - 4) = 3h - 4

Add the two:
(- 2h + 1) + (3h - 4)  = - 2h + 1 + 3h - 4

Group like terms

- 2h + 3h + 1 - 4

-2h + 3h = h

+1 - 4 = -3

- 2h + 1 + 3h - 4 = h - 3

You want the boxes of the pyramid shown filled with mixed numbers such that each box is the sum of the two numbers below it.

Strategy

As the example shows, each box is filled with the difference between the box above and the one adjacent. Work must necessarily proceed from the top down.

Math

As you know, the difference of fractions can be computed as ...

  [tex]\dfrac{a}{b}-\dfrac{c}{d}=\dfrac{ad-bc}{bd}[/tex]

Of course the number 1 can be written in terms of denominator d as ...

Additional comment

In a couple of places the denominators have a common factor.

For example, 13/15 and 5/9 have denominators that have a common factor of 3: 15=3·5 and 9=3·3. When we did the cross multiplication to find the difference, we divided the cross products by that common factor so the resulting fraction would be in lowest terms.

That is, we used 13·9/3 = 39 and 15·5/3 = 25 for the numerator values, and 15·9/3 = 45 for the denominator value.

You will also recognize that 6+(-2/15) became 5+13/15 by using 6 = 5+15/15.

Many calculators and spreadsheets can perform arithmetic on mixed numbers and give a mixed number result. (That is how we checked our work.)

one positive integer is 5 less than 4 times another their product 21 the integers are 3 and 7

Answers

Solving a system of equations we will see that the two integers are 3 and 7.

How to find the two integer numbers?

Let's define the two positive integers as x and y.

With the given information, we can write a system of equations to get:

x = 4y - 5

x*y = 21

Now we can replace the first equation intothe second one to get:

(4y - 5)*y = 21

4y^2 - 5y = 21

4y^2 - 5y - 21 = 0

Now we have a little quadratic equation, we can use the quadratic formula to solve this.

[tex]y = \frac{5 \pm \sqrt{(5)^2 - 4*4*-21} }{2*4} \\\\y = \frac{5 \pm 19 }{8}[/tex]

We know that the integers are positive, so we need to take the positive solution:

y = (5 + 19)/8 = 24/8 = 3

And the other number is:

x = 4*3 - 5

x = 12 - 5 = 7

These are the two integers.

The equation of the line that is perpendicular to 5x-8y=-6 and passes through (4,-4) is y = (-8/5)x + 16/5.

What are Parallel lines?

Parallel lines are two or more lines in a coordinate plane that are equidistant from each other at all coordinates.

The given line can be rewritten in slope-intercept form as y=(5/8)x+(3/4), where the slope is 5/8. So, any parallel line will also have a slope of 5/8.

Using the point-slope form of a line, we can write the equation of the line as:

y - (-4) = (5/8)(x - 4)

Simplifying, we get:

y = (5/8)x - 23/8

Therefore, the equation of the line that is parallel to 5x-8y=-6 and passes through (4,-4) is y = (5/8)x - 23/8.

The slope of the given line is 5/8, so the slope of any line perpendicular to it will be -8/5.

y - (-4) = (-8/5)(x - 4)

Simplifying, we get:

y = (-8/5)x + 16/5

Therefore, the equation of the line that is perpendicular to 5x-8y=-6 and passes through (4,-4) is y = (-8/5)x + 16/5.

Speed is decreasing Speed is constant Speed is not constant; Object is at rest

Answers

The most accurate statement is "Speed is decreasing." This means that the object is moving at a decreasing velocity over the 10 seconds.

What is the Speed is constant?

When we say that the speed of an object is constant, it means that the magnitude of the velocity of the object remains unchanged over time. In other words, the object is moving at a steady pace and its speed does not vary.

The statement "Speed is not constant; Object is at rest" is not accurate.

From the position-time graph, it is clear that the object is moving in one direction and its position is changing with time. Hence, the object is not at rest.

Furthermore, the slope of the position-time graph gives us the velocity of the object, and from the graph, it appears that the slope is changing with time, which means that the speed is not constant. Hence, the statement that "Speed is constant" is also not accurate.

Hence, the most accurate statement is "Speed is decreasing." This means that the object is moving at a decreasing velocity over the 10 seconds.

Answers

The synthetic division process involves dividing the polynomial by a linear factor in a compact manner. In this case, we are dividing the polynomial 4x^4 - 9x^3 + 14x^2 - 12x - 1 by x - 1.

To perform synthetic division, we first write the coefficients of the polynomial in a row and add a zero at the end. Then, we divide the first coefficient (4) by the leading coefficient of the divisor (x - 1), and write the result (4) above the next coefficient (-9). Next, we multiply the divisor (x - 1) by the first quotient (4) and subtract the result from the row. The new row of coefficients is the result of this subtraction. Repeat this process until all coefficients have been processed or a remainder is left.

Here is the process:

-4  4  14 -12 -1

-4  4  14 -12 -1

If we are to write the following polynomial in descending powers of the variable and with no missing powers 3x^3 -70, it would be 3x^3 - 70 + 0x^2 + 0x + 0

What is a Polynomial?

A polynomial is an equation made up of coefficients and indeterminates that uses only the addition, subtraction, multiplication, and powers of positive-integer variables.

Hence, it can be seen that descending order is basically when the power of a term decreases for each succeeding term. For example, x3 + x2 + x or 2 x4 + 3 x2 + 7 x are arranged in descending order. Descending order is more commonly used.

The polynomial in descending powers of the variable with no missing powers is:

3x^3 - 70 = 3x^3 - 70 + 0x^2 + 0x^1 + 0x^0

= 3x^3 - 70 + 0x^2 + 0x + 0

Answers

The Coalition for Airline Passengers Rights, Health, and Safety averages 400 calls a day to help stranded travelers deal with airlines. The hotline is staffed for 16 hours a day.

To calculate the average number of calls in different time intervals and the probability of different events related to these calls.

Part 1:

a. 60-minute interval average number of calls: 400/16 = 25 calls

30-minute interval average number of calls: 25/2 = 12.5 calls

15-minute interval average number of calls: 12.5/2 = 6.25 calls

Part 2:

b. To find the probability of exactly 6 calls in a 15-minute interval, we can use the Poisson distribution formula. Let's assume that the average number of calls in a 15-minute interval is 6.25. Then, the probability of exactly 6 calls in a 15-minute interval is:

P(6 calls) = (e^-6.25)*(6.25^6)/6! = 0.0686

c. To find the probability of no calls in a 15-minute interval, we can use the Poisson distribution formula. Let's assume that the average number of calls in a 15-minute interval is 6.25. Then, the probability of no calls in a 15-minute interval is:

P(0 calls) = e^-6.25 = 0.0047

d. To find the probability of at least two calls in a 15-minute interval, we can use the cumulative distribution function of the Poisson distribution. Let's assume that the average number of calls in a 15-minute interval is 6.25. Then, the probability of at least two calls in a 15-minute interval is:

P(X >= 2) = 1 - P(0 calls) - P(1 call) = 1 - 0.0047 - (e^-6.25)*(6.25^1)/1! = 0.9906

Thus, the average number of calls in a 60-minute interval is 25, in a 30-minute interval is 12.5, and in a 15-minute interval is 6.25. The probability of exactly 6 calls in a 15-minute interval is 0.0686, the probability of no calls in a 15-minute interval is 0.0047, and the probability of at least two calls in a 15-minute interval is 0.9906.

Abby's solution.

Answers

Answer: One way to check Abby's solution using a number line and counting on is as follows:

Start at 5 2/5 on the number line.

Subtract 2 1/2 by counting left 2 and a half units.

Check if the result is 2 9/10.

If the result of the subtraction is 2 9/10, then Abby's solution is correct. If not, then the solution is incorrect and needs to be re-evaluated.

Using this method, we can visually see the subtraction and verify the result.

Answer:

1.  sin∠EDA is equal to sin∠EBC

2.  sin∠CEB is not equal to sin∠EBC

3.  cos∠BEC is equal to sin∠EBC

4.  cos∠ADE is not equal to sin∠EBC

5.  sin(90 - m∠EBC) is not equal to sin∠EBC

6.  cos(90 - m∠EDA) is equal to sin∠EBC

Step-by-step explanation:

From inspection of the given diagram, ∠EAD = ∠ECB = 90°.

According to the vertical angles theorem, ∠BEC = ∠DEA.

According to AA similarity theorem, ΔADE ~ ΔCBE

Therefore, ∠EDA = ∠EBC.

This means that:

sin∠EDA is equal to sin∠EBCsin∠CEB is not equal to sin∠EBC

[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

Since  cos∠BEC = CE/BE  and  sin∠EBC = CE/BE  then:

cos∠BEC is equal to sin∠EBC.

As  ∠BEC ≠ ∠ADE  then:

cos∠ADE is not equal to sin∠EBC.

As  sin(90° - x) = cos(x)  then  sin(90 - m∠EBC) = cos∠EBC.

As  cos∠EBC ≠ sin∠EBC  then:

sin(90 - m∠EBC) is not equal to sin∠EBC

As  cos(90° - x) = sin(x)  then  cos(90 - m∠EDA) = sin∠EDA.

As  sin∠EDA = sin∠EBC  then  cos(90 - m∠EDA) = sin∠EBC.

Hence:

cos(90 - m∠EDA) is equal to sin∠EBC.

For the right prism having volume of 360 cm², the total surface area is 408 cm².

What is surface area?

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

The right prism has measurements (6 , 8, 10).

The perpendicular is 6 cm, the base is 8 cm.

The area of base is -

Area = 1/2 × base × height

Substitute the values into the equation -

Area = 1/2 × 8 × 6

Area = 24 cm²

The volume of the prism is 360 cm³.

Volume = Area of base × height

Substitute the values into the equation -

360 = 24 × height

height = 260 / 24

height = 15 cm

The lateral surface area of the prism is -

Lateral Surface area = Perimeter of base × height

Substitute the values into the equation -

LSA = (8+6+10) × 15

LSA = 24 × 15

LSA = 360 cm²

The total surface area of the prism is -

Total Surface Area  = Lateral Surface Area + 2(Area of base)

Substitute the values into the equation -

TSA = 360 + 2(24)

TSA = 360 + 48

TSA = 408 cm²

Therefore, the total surface area is 408 cm².

countries in the world. The circle for United States has a radius of 4.2 cm and the circle
for India has a radius of 8.7 cm. If 4% of the world's population is in United States, what
percentage of the world's population is in India? Round to the nearest percent.

Answers

Answer:

17%

Step-by-step explanation:

area represents the populations

United States has a radius of 4.2 cm and

India has a radius of 8.7 cm.

If 4% of the world's population is in United States,

what percentage of the world's population is in India

US π r² = π*4.2²

India π r² = π*8.7²

so india/US = 4.29

so india = 4.29 *4% = 17%
