How do i find the vertical asymptote?
levacccp [35]

Answer:

  find the value of x that makes the denominator zero: x = 7

Step-by-step explanation:

A vertical asymptote shows up where the denominator is zero. As the denominator gets closer to zero, the function value gets larger without bound (unless there is a numerator factor that cancels the one in the denominator).

To find the value of x at the vertical asymptote, solve the equation ...

  denominator = 0

  x - 7 = 0

  x = 7 . . . . . . . add 7 to both sides

Rationalize the denominator of square root of negative 9 over open parentheses 4 minus 7 i close parentheses minus open parenthe
AlekseyPX
The answer is
\frac{-6i-3}{5}.

Before we rationalize the denominator, we must simplify the numerator and denominator.  We evaluate the square root on the top, and combine like terms on the bottom:
\frac{\sqrt{-9}}{(4-7i)-(6-6i)}&#10;\\&#10;\\=\frac{\sqrt{9i^2}}{4-6-7i--6i}&#10;\\&#10;\\=\frac{3i}{-2-i}

To rationalize the denominator, we multiply by the conjugate.  The conjugate is found by making the imaginary term of the complex number, the i part, the opposite sign.  The conjugate of -2-i is -2+i:

\frac{3i}{-2-i}\times \frac{-2+i}{-2+i}&#10;\\&#10;\\=\frac{3i(-2+i)}{(-2-i)(-2+i)}&#10;\\&#10;\\=\frac{3i\times -2 + 3i\times i}{-2\times -2 + -2\times i + -2\times -i + -i\times i}&#10;\\&#10;\\=\frac{-6i+3i^2}{4-2i+2i-i^2}&#10;\\&#10;\\=\frac{-6i+3(-1)}{4-i^2}=\frac{-6i-3}{4-(-1)}=\frac{-6i-3}{5}
