What is the coordinate of the point which divides a line segment in a specified ratio?

Suppose that there is a line segment {AB} such that a point P(x,y) lying on that line segment{AB} divides the line segment {AB} in m:n, then, the coordinates of the point P is given by:

[tex](x,y) = \left( \dfrac{mx_2 + nx_1}{m+n} , \dfrac{my_2 + ny_1}{m+n} \right)[/tex]

Line segment RW has endpoints R(4, 5) and W(6, 20). Point P is

on RW such that RP: PW is 2:3.

[tex](x,y) = \left( \dfrac{2(6) + 3(-4)}{2+3} , \dfrac{2(20) + 3(5)}{2+3} \right)\\\\(x,y) = \left( \dfrac{12- 12}{5} , \dfrac{40+15}{5} \right)\\\\(x,y) = \left( \dfrac{0}{5} , \dfrac{55}{5} \right)\\\\(x,y) = (0, 11)[/tex]

Which expression represents the number of ways that a president and vice president can be chosen out of a group of 15 people?

Answers

Answer: The answer is 15 * 14

Step-by-step explanation:

You start with 15 people to choose from to select a president, so you have 15. After removing one person 15-1,=14 you have fourteen people to choose from, to select a vice president. This gives you 15*14.

The expression that can be used to represent the number of ways that a president and a vice-president can be chosen out of a group of 15 people is 15×14 or ¹⁵P₂.

What is Permutation?

Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.

[tex]^nP_r = \dfrac{n!}{(n-r)!}[/tex]

where,

n is the number of choices available,

r is the choices to be made.

The number of people that are available for the post of the president is 15, while the number of people that are available for the post of vice-president after the president is selected is 14. Therefore,

Number of ways in which president and vice-president can be selected

= ¹⁵P₂

= 15 × 14

Hence, the expression that can be used to represent the number of ways that a president and a vice-president can be chosen out of a group of 15 people is 15×14 or ¹⁵P₂.

Expand or factor each of the following expressions to determine which expressions are equivalent.

Answers

Answer:

[tex]9x^{2}+3x-20=(3x+5)(3x-4)[/tex]

Step-by-step explanation:

We need to drag the tiles and place them in boxes to form the correct pairs.

The given options are:-

1) [tex]9x^{2}+3x-20[/tex]

2) [tex](4x-3y)^{2}[/tex]

3) [tex](3x+5)(3x-4)[/tex]

4)[tex](3x+2)(9x^{2} -6x+4)[/tex]

First we simplify the all given factor and then compare with provided options

2) [tex](4x-3y)^{2}[/tex]

=[tex]16x^{2}+9y^{2}-24xy[/tex]

3) [tex](3x+5)(3x-4)[/tex]

[tex]9x^{2}-12x+15x-20[/tex]

[tex]9x^{2}+3x-20[/tex]

Here we can see equation (3) match with (1)

so, [tex]9x^{2}+3x-20=(3x+5)(3x-4)[/tex]

Hence, the correct match is shown in figure-1

The expressions that are equivalent should be matched as follows;

9x² + 3x - 20 ↔ (3x + 5)(3x - 4)

How to match the equivalent expressions?

In order to match the equivalent expressions, we would have to either expand or factor each of the given expressions as follows;

9x² + 3x - 20

By applying the sum-product pattern, we have:

9x² + 15x - 12x - 20

By writing the common factor from the two pairs, we have:

(9x² + 15x) + (-12x - 20)

3x(3x + 5) - 4(3x + 5)

(3x + 5)(3x - 4)

Next, we would expand the expression (4x - 3y)²;

(4x - 3y)(4x - 3y)

16x² - 12xy - 12xy + 9y²

16x² - 24xy + 9y²

In a rectangle MPKN, the diagonals intersect each other at point O. A line segment OA is an altitude of a triangle MOP, and m∠AOP = 18°. Find the measure of ∠ONK.

Answers

To find the measure of ∠ONK in rectangle MPKN with given conditions, it's determined through the congruency of triangles and properties of a rectangle that ∠ONK is 72°.

The question involves finding the measure of ∠ONK in rectangle MPKN, where the diagonals intersect at point O, and a line segment OA is an altitude of triangle MOP with m∠AOP = 18°. Given the properties of a rectangle, we know that its diagonals bisect each other and are equal in length. Therefore, triangles MOP and NOP are congruent.

Because OA is the altitude to hypotenuse MP of triangle MOP, it creates two right triangles, OAM and OAP. The angle ∠AOP is given as 18°, which means ∠MOA = 90° - 18° = 72° since triangle OAM is a right-angled triangle. Because the diagonals of the rectangle bisect each other at O, triangle ONP is congruent to triangle OMP, and hence ∠ONK (which is also ∠ONP) is equal to 72° as angle ∠ONP is supplementary to ∠MOA in rectangle MPKN.

The square of the sum of two consecutive positive even integers is 4048 more than the sum of the squares of these two numbers. Find the two numbers.

Answers

Answer:

44, 46

Step-by-step explanation:

The integers are both even, so if the smaller one is x, then the larger one is x+2.

Therefore:

((x) + (x+2))² = 4048 + (x)² + (x+2)²

(2x + 2)² = 4048 + x² + x² + 4x + 4

4x² + 8x + 4 = 2x² + 4x + 4052

2x² + 4x - 4048 = 0

x² + 2x - 2024 = 0

(x + 46) (x - 44) = 0

x = -4+, 44

Since x must be positive, x = 44.  And x+2 = 46.  So the numbers are 44 and 46.

Step-by-step explanation:

If a line passing through two point then the equation of line is

From the given graph it is clear that the line of best fit passing through the points (0,0) and (14,45). So, the equation of line of best fit is

The equation of line of best fit is [tex]y=\frac{45}{14}x[/tex], therefore the correct option is C.

Subtract: (2x3+7x2−4)−(2x2+4x−10)

Answers

Final answer:

To subtract the given expressions, first, simplify each expression separately by combining like terms. Then subtract the second expression from the first expression by distributing a negative sign and adding it to the first expression.

Explanation:

To subtract the given expressions, (2x^3+7x^2-4) - (2x^2+4x-10), we need to simplify each expression separately and then subtract them. First, combine like terms within each expression. Then, subtract the terms of the second expression from the first expression. This can be done by distributing a negative sign to each term in the second expression and then adding it to the first expression.

So, (2x^3+7x^2-4) - (2x^2+4x-10) = 2x^3+7x^2-4 - 2x^2-4x+10.

Combining like terms, we get 2x^3+(7x^2-2x^2)+(-4-4x)+(10). Simplifying further, we have 2x^3 + 5x^2 - 4x + 6. Therefore, the result of the subtraction is 2x^3 + 5x^2 - 4x + 6.

The lateral area of a right cylinder which has a base diameter of 12 cm and a height of 8 cm is?

Answers

Answer:

[tex]A = 301.59\ cm^2[/tex] or [tex]A=96\pi\ cm^2[/tex]

Step-by-step explanation:

The lateral area of a cylinder is calculated by the following formula

[tex]A = 2\pi r * h.[/tex]

Where r is the radius of the right cylinder and h is the height

In this case we know that the diameter d of the cylinder is

[tex]d=2r\\\\r=\frac{d}{2}\\\\r=\frac{12}{2}\\\\r=6\ cm[/tex]

[tex]h=8\ cm[/tex]

Therefore the lateral area is:

[tex]A = 2\pi*6 * 8.[/tex]

[tex]A = 96\pi[/tex]

[tex]A = 301.59\ cm^2[/tex]

Answer:

The lateral area of a right cylinder = 96π cm²

Step-by-step explanation:

Points to remember

The lateral area of a right cylinder  = 2πrh

Where r - Radius of cone and

h - Height of cone

To find the lateral surface area

Here diameter d = 12 cm

then radius r = d/2 = 12/2 = 6 cm

And h = 8 cm

Lateral surface area =  2πrh

= 2 * π *6 * 8 = 96π cm²

Therefore the lateral area of a right cylinder = 96π cm²
