Answer:
x = ± 2
Step-by-step explanation:
given
40 - x² = 0 ( add x² to both sides )
40 = x² or
x² = 40 ( take the square root of both sides )
x = ±
= ±
= ± 2

Answer:
The complex number
belongs to the third quadrant of the complex plane.
Step-by-step explanation:
Let be
. In the complex plane, if
(real component) and
(imaginary component), the number belongs to the third quadrant of the complex plane. The complex number
belongs to the third quadrant of the complex plane.
First you would take both radius' and add them. Once you add them, subtract the sum by 42. that will give you the distance between the gap of the circles. now that you have that distance, add 19 and 11 and your result is your final answer.
The Power of a Point theorem tells us, if we draw a line from a certain point, no matter which line we choose, the product of the two distances from the point to the line's intersections with the circles will be constant (or, if the line is tangent to the circle, the value will be equal to the square of the distance to the point of tangency). So,applying the tangent rule to the

-distance intersection and the two-intersection rule to the other, we have

, so taking the square root of the equation gives

.
