Answer:
$59.9088 (or approx. $60)
Step-by-step explanation:
0.12 x $53.49
= $6.4188
$6.4188 + $53.49
= $59.9088

Black lives matter , yes they do
The vertex form of the equation is f(x)=-2(x-2)^2 - 4. The standard form of the equation is f(x)=-3x^2 + 12x - 16
ANSWER IS C
Answer:
C. 4(cos(300°) +i·sin(300°))
Step-by-step explanation:
The magnitude will be ...
magnitude = √(2^2 +(-2√3)^2) = √(4+12) = 4
The negative imaginary part puts the angle in the 4th quadrant. The answer choice with a magnitude of 4 and a 4th-quadrant angle is ...
4(cos(300°) +i·sin(300°))
__
If you want to figure the angle, it will be ...
angle = arctan(Im()/Re()) = arctan(-2√3/2) = arctan(-√3) = -60°
The corresponding 4th-quadrant angle is 300°.

<em>Comment on answer choices</em>
Answer choice A is <em>another representation of the same number</em>. Typically, we want the magnitude to be positive in polar form, so that answer can be avoided on those grounds.
