Answer: third option.
Step-by-step explanation:
A tangent of a circle is defined as a line that touches that circle in exactly one point.
You can observe in the figure attached that:
The segment MN and the segment ST are not the tangent of the given circle, because this segments intersect it in two points.
The segment RO is the radius of the circle.
The segment PQ touches the circle in one point.
Therefore, the segment PQ is the tangent of the circle.
The answer to 1 is (E) All of the above. This is because a negative cannot be under a square root and it comes out as an i.
The answer to 2 is (B) a is real and b is imaginary. This is because anything that has an "i" attached to it is considered imaginary.
Polynomial division yields

As

, you have the remainder term approaching

, so the horizontal asymptote is the line

.
<span>Northwest is 45 degrees north of west. If a car travels a distance x miles northwest, its northerly component gains x/sqrt(2) miles and its easterly component LOSES xsqrt(2)/ miles.
Resultant height is h = 4500 + 100x/sqrt(2) - 75x/sqrt(2) = [25/sqrt(2)]x + 4500
dh/dt = [25/sqrt(2)]dx/dt = [25/sqrt(2)]v </span>
25/100 = 1/4 (divide both numerator and denominator by 25)
350/1000 = 35/100 = 7/20.
