Answer:

7.56

Step-by-step explanation:

you would cross multiply and it would look like this (42/100)x (x/18)

first you multiply 42 x 18= 756 then divide that by 100 equaling 7.56

What are the coordinates of the point on the directed line segment from (4, -3)(4,−3) to (9, -8)(9,−8) that partitions the segme

jekas [21]

Answer:

(7, -6)

Step-by-step explanation:

You want to find point X on the segment from A to B such that ...

(X -A)/(B -X) = 3/2

2(X -A) = 3(B -X) . . . . . . cross multiply

2X -2A = 3B -3X . . . . . eliminate parentheses

5X = 2A +3B . . . . . . . . add 3X +2A

X = (2A +3B)/5 . . . . . . . divide by 5

Filling in the given points for A and B, we have ...

X = (2(4, -3) +3(9, -8))/5 = (8+27, -6-24)/5 = (35, -30)/5

X = (7, -6)

The point that divides the segment in the proportions 3:2 is (7, -6).

Find the distance from P to l.

ki77a [65]

$Equation\ of\ a\ line\ from\ 2\ points (x_1;\ y_1);\ (x_2;\ y_2):\\\\y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\(-4;\ 2)\ and\ (3;-5)\\subtitute:\\\\y-2=\dfrac{-5-2}{3-(-4)}\cdot(x-(-4))\\\\y-2=\dfrac{-7}{7}\cdot(x+4)\\\\y-2=-(x+4)\\\\y-2=-x-4\ \ \ |add\ x\ and\ 4\ to\ both\ sides\\\\x+y+2=0\\-------------------\\$

$Point-line\ distance\\l:Ax+By+C=0;\ (x_0;\ y_0)\\\\d=\dfrac{|Ax_0+By_0+C|}{\sqrt{A^2+B^2}}\\\\x+y+2=0\to A=1;\ B=1;\ C=2\\(1;\ 2)\to x_0=1;\ y_0=2\\subtitute\\\\d=\dfrac{|1\cdot1+1\cdot2+2|}{\sqrt{1^2+1^2}}=\dfrac{|1+2+2|}{\sqrt2}=\dfrac{|5|}{\sqrt2}=\dfrac{5}{\sqrt2}=\dfrac{5\cdot\sqrt2}{\sqrt2\cdot\sqrt2}\\\\=\boxed{\dfrac{5\sqrt2}{2}}$
