Given: <span>2x-y-3=0.
find </span>equation for the line perpendicular to the given line that goes through the given point:<span>
(2;-1)koord of direction vector (i`m not know how it is called at you, because i'm from russia)</span><span>
=> (x-0)/2=(y-4)/-1 (</span>canonical <span>equation)
=>x+2y-8=0(general </span><span>equation)
</span>
<span>further:
{x+2y-8=0
{2x-y-3 =0 => y=13/5 x=14/5
(14/5; 13/5) - koord point on line
</span>|dist|=sqrt( (14/5-0)^2 + (13/5-4)^2 ) = sqtr(7.72) = 2.78
Удачи!

Last one definitely, that may not be much help though. Forgive me
Answer:
2#2=4+1=5
3#9=27+1=28
6#8=48+1=49
13#19=247+1=248
7#6=42+1=43
Step-by-step explanation:
If Na'ilah invented a new use for the symbol #, she decided to use it like this.
so let the numbers multiplied by the symbol #be x and y
x#y, and then you add 1 to the result of x#y.
so in total it will be like x#y+1
so just substitute the numbers you like or you are given. In this case i chose the numbers above.
Well, if any number is higher than '5' it turns one number more. So, here's a good rhyme to help you: "Five or more, up the score, Four or less, let it rest." The maximum number it could be would have to be '444' because it is not bigger than 445, which would turn to 500.
