Answer:
If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.
We also know that Pythogoras' theorem only holds for right angled triangles.
The hypotenuse is 12 + 8 as 12 is the radius so is 20.
16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.

Step-by-step explanation:
Answer: The vertical asymptoms are " x = 3" and " x = -3 " .
__________________________________________________
The answer is: " x = ± 3 " .
__________________________________________________
Explanation:
________________________________________________________
The "denominator" cannot equal "0" ; since one cannot "divide by "0" ;
So; set the "denominator" equal to "0" ;
________________________________________________________
→ " x² − 9 <span>= 0 " ; Solve for all values of "x" ;
</span>
Add "9" to each side of the equation:
→ x² − 9 + 9 = 0 + 9 ;
to get:
→ x² = 9 ;
Take the square root of each side of the equation;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ √(x²) = √9 ;
→ |x| = 3 ;
→ x = <span>± 3 .

The answer is: " x = ± 3 " .

4/9 > 33/100 > 1/7 > 2/25
Turn the decimals to fractions.
0.33 <span>· 100 = 33/100
0.08 = 2/25</span>
