enot [183]

Answer:

<em>Correct answer: Option b</em>

Step-by-step explanation:

<u>Distance Between Two Points </u>

Given two points A=(ax,ay) and B=(bx,by), the distance between them can be computed by the Pythagoras's formula

$\displaystyle d=\sqrt{(bx-ax)^2+(by-ay)^2)}$

The points of the question are A(x,y) and F(0,p), thus applying the formula:

$\displaystyle d=\sqrt{(x-0)^2+(y-p)^2)}$

$\boxed{\displaystyle d=\sqrt{x^2+(y-p)^2)}}$

Correct answer: Option b

Lilit [14]

Z is inversely proportional to X is the same as
z is directly proportional to 1/X
which can be written like this:-
y=k/X
________
0.5=k/6
0.5*6=k/6*6
k=3 ;
________
z = 3/14
Z = 0.2
