Answer:

Right

Step-by-step explanation:

In a number line, numbers proceed from the left to the right in ascending order.

Given the two operations

-20 >-21

-19>-20

Since -20 is greater than -21 , -20 is the location to the right of -21.

Also since -19 greater than -20 on the number line -19 is located to the right of -20 on the number line.

In general, numbers greater than are to the right of that number and numbers less than a number are to the left of the number.

Answer:

21°

Step-by-step explanation:

A boat captain, lighthouse and its base form a right triangle.

<u>We need to find the angle opposite to 22 ft side:</u>

tan x = 22/103
x = arctan (22/103)
x = 21°

<em>Note, option D should read 21° not 11°</em>

What are the real and complex solutions of the polynomial equation X^3-216=0

vazorg [7]

Answer:

$6,\ -3+3\sqrt{3}i,\ -3-3\sqrt{3}i$

Step-by-step explanation:

Factor the equation $x^3-216=0$ using formula for difference of the cubes:

$x^3-216=(x-6)(x^2+6x+36),$

then

$x-6=0\ or\ x^2+6x+36=0.$

1. The equation $x-6=0$ has real solution $x=6.$

2. The equation $x^2+6x+36=0$ has negative discriminant $D=6^2-4\cdot 36=36-144=-108,$ then it has two complex solutions

$x_{1,2}=\dfrac{-6\pm 6\sqrt{3}i}{2}=-3\pm3\sqrt{3}i.$
