Is line AB tangent to the circle
1 answer:
no it is not a tangent
for it to be a tangent to the circle Angle A would have to be a right angle.
to check if its a right angled triangle, you can use pythagoras.
this shows it is not a right angled triangle because this calculation does not give us 10.3
therefore it is not a tangent and there is no right angle

The number added to the polynomial by completing the square is
Explanation:
Given that the polynomial is
We need to determine the number that is added to the polynomial to complete the square.
The last term of the polynomial can be determined by dividing the term 17 by 2 and then squaring the term.
Thus, we have,
Last term =
Now, squaring the term, we have,
Last term =
Thus, the number added to the polynomial by completing the square is
