X would be -3.
hops this helps mark me brainlist
f(3) = 1
substitute x = 3 into f(x)
f(3) = (2 × 3) - 5 = 6 - 5 = 1
Answer: A
Step-by-step explanation:
3000 impressions
A CTR 2% conversion 25%
2% of 3000 = 2/100 . 3000 = 60 clicks
25% of 60 = 25/100 . 60 = 15
B CTR 4% conversion 10%
4% of 3000 = 4/100 . 3000 = 120 clicks
10% of 60 = 10/100 . 120 = 12
This way, A converted more than B
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!

100 square centimeters means the dimensions are 10x10
but the actual floor will be 1cm:2ft
so 10cm=20feet
making the dimensions 20feetx20feet
the area of the actual floor is 400 feet
