Select the correct answer.

Sonja [21]

Answer:

B) 5 + 17i is your answer.

Step-by-step explanation:

In order to write this equation as a complex number in standard form, you must first simplify each term.

Apple the distributive property.

21 - 4i - 1 * 16 - (7i) + 28i

Multiply -1 by 16.

21 - 4i -16 - (7i) + 28i

Multiply 7 by -1.

21 - 4i - 16 - 7i + 28i

Now simplify by adding terms :)

Subtract 16 from 21.

5 - 4i - 7i + 28i

Subtract 7i from -4i.

5 - 11i + 28i

Add -11i and 28i.

= 5 + 17i

For the quadratic function f(x)=x^2-6x-27, determine and accurately express each of the key features listed below.

Verizon [17]

Answer:

1) $(x,y) = (0,-27)$ , 2) $V(x,y) = (3, -36)$ .

Step-by-step explanation:

1) The ordered pair of the parabola is:

$f(0) = 0^{2} - 6\cdot (0) -27$

$f(0) = -27$

$(x,y) = (0,-27)$

2) The quadratic function needs to be rearranged into the standard form:

$y = x^{2}-6\cdot x -27$

$y = x^{2} - 6\cdot x + 9 -9 -27$

$y = (x-3)^{2}-36$

$y + 36 = (x-3)^{2}$

The vertex is $V(x,y) = (3, -36)$ .
