Given three points A(-7, 1), B(m, 6) and P(-1, n). If the point P divides AB internally in the ratio of 3: 2, find the values of

vesna_86 [32]

Answer:

m = 3 , n = 4

Step-by-step explanation:

<u>Using Section Formula.</u>

<u /> $If \ the \ line \ segment \ AB \ where \ A = (x _1, y_1) \ and \ B = (x_2, y_2) \ divided \ by \ P =(x , y) \ in \ the \ ratio \ a : b,\\\\Then \ the \ points \ of \ P \ \\\\x = \frac{ax_2 + bx_1}{a+b} \ and \ y = \frac{ay_2 + by_1}{a+b}$ <u />

$Here (x_1 , y_ 1 ) = ( -7 , 1 ) \ and \ (x_ 2 , y _ 2 ) = (m , 6)\\\\ratio\ a:b = 3 : 2\\\\Therefore, P (x, y) \\\\x = \frac{3m + (2\times -7)}{5} \ \ \ \ \ \ \ \ \ \ \ [ \ x = -1 \ ] \\\\-1 = \frac{3m - 14}{5}\\\\- 5 = 3m - 14\\\\-5 + 14 = 3m\\\\9 = 3m \\\\m = 3$ <u />

$y =\frac{3\times 6 + 2 \times 1}{5}\\\\n = \frac{18 + 2}{5} = \frac{20}{5} = 4$

Please help it's fricking urgent

Gwar [14]

Answer:

Kaden had $17 at first

Step-by-step explanation:

Ben = x

Kaden = x - 10

x + 4

x - 10 + 4 = x -6

x - 6 = $\frac{7}{9}$ x

9(x - 6) = 7x

9x - 54 = 7x

2x = 54

x = 27

x - 10 = 27 - 10 = 17

What single decimal multiplier would you use to decrease by 6% followed by a 19% increase?

s344n2d4d5 [400]

Decrease by 6% = 100 - 6 = 94

Increase this by 19%

= 19/100 x 94
= 17.86

94 + 17.86 = 111.86

\ 100 = 1.1186

Answer:

c) 2 x + 17

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given expression

$5( x+\frac{4}{5} )-\frac{1}{4} (12 x-52)$

= $5( x)+5(\frac{4}{5} )-\frac{1}{4} (12 x)+\frac{1}{4} (52)$

= 5x + 4 - 3x + 13

= 2 x + 17

$5( x+\frac{4}{5} )-\frac{1}{4} (12 x-52) = 2 x +17$

9. How many strings can be formed by ordering the letters SCHOOL using some or all of the letters?

Liono4ka [1.6K]

The number of strings that can be formed by ordering the letters SCHOOL using some or all of the letters is 1440 strings

<h3>What is Permutation in Mathematics ?</h3>

Permutation can be defined as number of ways in which things can arranged.

We were given to find how many strings that can be formed by ordering the letters SCHOOL using some or all of the letters.

First of all, How many distinct letters are in the word SCHOOL ?

The distinct letters are 5 in numbers.

What is the total number of letters in the word SCHOOL ?

The total number of letters is 6.

Then

6! + 5 $P_{5}$

That is, 6 factorial + 6 permutation 5

( 6 x 5 x 4 x 3 x 2 x 1 ) + 6!/( 6 - 5)!

720 + 720

1440 strings

Therefore, the number of strings that can be formed by ordering the letters SCHOOL using some or all of the letters is 1440 strings
