What is a median of a triangle?

A median of a triangle is a line segment that extends from a vertex of a triangle to the midpoint of the side opposite the vertex

The midpoints of the sides of the triangle = F, B, and D

The midpoint of EC = F

The midpoint of AC = B

Midpoint of AE = D

A. The lines CD, BE, and FA are called median lines

The point of intersection of the three median lines of a triangle is the centroid of the triangle.

The point G is called the centroid of the triangle

B. The centroid of a triangle and center of gravity of the triangle are located at the same position in a uniformly dense triangle, therefore, G is the center of gravity, True, T

C. In the relationship of a median, we get;

AG = (2/3)·FA

GF =  (1/3)·FA

Therefore, AG = 2·(GF)

GF = 0.5 × AG

GF = 0.5 × 10 = 5

GF = 5

D. DG = (1/3) × DC

Therefore; DC = 3 × DG

DG = 6, therefore, DC = 3 × 6 = 18

DC = 18

E. EB = 21

GB = (1/3) × EB

Therefore; GB = (1/3) × 21 = 7

GB = 7

What is standard notation?

A standard notation is a method of writing a given number, equation, or expression in a specific format that adheres to certain rules. 4.5 billion years, for example, is written as 4,500,000,000 years.

The main reason for converting numbers to scientific notation is to make calculations involving unusually large or small numbers easier.

Even though zeros are no longer always seemed to set the decimal point, all digits in a scientific notation number are significant.

Here, it is given that,

The number of bacteria found in  1 milliliter of water = 1,500,000.

So,

The number of bacteria in 100 milliliters of water = 1,500,000 x 100

What will the dividend income be on W number of shares of XYZ stock if XYZ distributes a $Y per share dividend?

Answers

Answer:

In general, the dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend.

Step-by-step explanation:

The dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend. This is because the dividend income is calculated by multiplying the number of shares that an investor owns by the amount of the dividend per share.

For example, if an investor owns W = 100 shares of XYZ stock and XYZ distributes a $Y = 5 per share dividend, then the investor's dividend income will be 100 * 5 = 500 dollars.

In general, the dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend.

The volume of a cylinder having height one and half of the radius is 12,936 m3 what minimum square cm of paper is needed to cover the curved surface area of the cylinder? The answer should be 1848m2. please solve my question.​

Answers

Answer:

Lateral Surface Area = 1848 m^2 (does not include the top and bottom)

Step-by-step explanation:

Vol Cylinder = pi*r^2 *h  

h = (3/2)r

Vol = pi*r^2((3/2)r)                     [We are told that the volume is 12,936 m^3]

pi*r^2((3/2)r) = 12,936 m^3  

pi*(3/2)*(r^3) = 12,936 m^3

pi*r^3 = (12,936 m^3)*(2/3)

pi*r^3 = 8,624 m

r^3 = (8,624 m)/(3.14)

r^3 = 2745.1

r = 14.0 m

Lateral Surface = 2*(pi)*r*h  [Lateral is just the curved portion of the right cylinder.

Find the measure of each acute angle in a right triangle where the measure of one acute angle is 8 times the measure of the other acute angle

Answers

The measure of the acute angles in the right triangle are 10 and 80 degrees.

How to find the angle of a right angle triangle?

A right angle triangle is a triangle that has one of its angles as 90 degrees.  The sides of a right angle triangle can be named base on the position of the angles. The sides includes hypotenuse side, opposite side and adjacent side.

The sum of angles in a right angle triangle is 180 degrees.  

The other measures of the right triangle are acute angles.

Any angle that measures greater than 0° and less than 90° is called an acute angle.

Hence, let's find the measure of the acute angles

let

x = measure of one acute angle

Hence,

x + 8x + 90 = 180

9x = 180 - 90

9x = 90

x = 90 / 9

x = 10

Therefore, the measure of the acute angles are 10 and 80 degrees.

(b) Find the value of k such that L1 and L2 are perpendicular.


This question is related to Linear functions, Answers: (a) k = -4, (b) k=1. Someone pls tell me how to get there though

Answers

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

(a)

given the equation of L1 is

2x - y = 3 ( subtract 2x from both sides )

- y = - 2x + 3 ( multiply through by - 1 )

y = 2x - 3 ← in slope- intercept form

with slope m = 2

• Parallel lines have equal slopes

then slope of L2 is m = 2

given the equation of L2 is

kx + 2y = 3 ( subtract kx from both sides )

2y = - kx + 3 ( divide through by 2 )

y = - [tex]\frac{k}{2}[/tex] + [tex]\frac{3}{2}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{k}{2}[/tex]

since slope of L1 and L2 are equal, both 2 , then

- [tex]\frac{k}{2}[/tex] = 2 ( multiply both sides by 2 to clear the fraction )

- k = 4 ( multiply both sides by - 1 )

k = - 4

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

(b)

given the slope of a line is m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]

Then

for L2 to be perpendicular to L1

- [tex]\frac{k}{2}[/tex] = - [tex]\frac{1}{2}[/tex] ( multiply both sides by - 1 )

[tex]\frac{k}{2}[/tex] = [tex]\frac{1}{2}[/tex] , thus

k = 1

Given that;

The length of a rectangular drainage pond is changing at a rate of 8 ft/hr and the perimeter of the pond is changing at a rate of 24 ft/hr.

Now,

We know that;

Perimeter of rectangle = 2 (Length + Width)

Substitute al the values, we get;

⇒ 24 = 2 (8 + x)

Energy manifests mechanically as work.

For the mentioned question-

Total acres of land planted = 2/5 acres.

Total time taken = 7/8 days.

Thus, unit rate in acres per day = Total acres of land planted / Total time taken

unit rate in acres per day = (2/5) / (7/8)

slope of the line that passes through (10, 4) and (5, 13). as a integer

Answers

The slope of the line that connects (10,4) and (5,13) is -9/5.

What is a slope?The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

Here given,

The two points are (10,4) and (5,13).

We have to find the slope that passes through the given points,

The formula to find slope(m) is,

The slope of the line that passes through (x1 , y1) and (x2,y2) is,

Slope(m) = y2 - y1 / x2 - x1

By substituting the values in x and y

Slope = 13 - 4 / 5 - 10

          = 9 / -5

Slope = -9/5

          = -1.8

Therefore the slope of line that passes through (10,4) and (5,13) is -9/5.
