From the equation, you can see that (3,-2) is the center of the circle (the terms are 0 for those x,y values). The mentioned point has the same y value as the center. That's good news, because it tells us that the tangent line is exactly vertical. The x coordinate is given as x=8. Vertical lines have an equation of x=... so x=8 is the right answer.
Answer: 9/81
Step-by-step explanation:
I did 3 to the second power then 3 to the fourth power. Then put them on top of each other. If the over is supposed to mean division then the answer would be 9.
Common solution for each problem:
let
1st point=(x1,y1)
&,
2nd point=(x2,y2),then,
distance between 1st and 2nd point is:
√[(x2-x1)²+(y2-y1)²]
Just replace these x2,y2,x1,y1 with given points and you will get required answer..
