State the domain and range and determine if it's a function?

if we do a <u>vertical line test</u> on that graph, we'll find that a vertical line will pass by and hit the line only once on its way down, only once meaning the graph is the graph of a function.

<h2>Range</h2>

well, is really how high and low it goes or namely over the y-axis.

well, it goes up up up to 3 then U-turns and back down it goes, now the graph has arrowheads, meaning the graph keeps on going towards infinity, vertically as well as horizontally since it's a parabola, so the range will be

<h2>[3 , +∞)</h2>

<h2>Domain</h2>

well, is simply how left and right it goes or namely over the x-axis.

judging from the arrowheads it moves from infinity to infinity, so

<h2>(-∞ , +∞).</h2>

How do I begin this equation
alex41 [277]
Trigonometry:
We know that   csc x = 1 / sin x    and π = 180°;
sin 5π/ 6 = sin 150° = 1/2
csc 2π / 3 = 1 / sin 120° = 1 / √3/2 = 2 / √3
Finally:
4 · 1/2 + 7 · ( 2 / √3 )² = 2 + 7 · 4/3 = 
= 2 + 28/3 = 2 + 9 1/3 =  11  1/3

1. The larger of two supplementary angles is 15 more than twice the measure of the smaller angle. Find each angle measure.Help
Anna71 [15]

Answer:

55 degrees and 125 degrees

Step-by-step explanation:

Supplementary means that they add up to 180.

x + y = 180

Let's let x be the larger angle.

x = 15 + 2y

The above equation comes from the information given, that it's 15 more than twice the smaller angle.

Now let's use substitution.

x + y = 180

(15 + 2y) + y = 180

15 + 3y = 180

3y = 165

y = 55

The smaller angle is 55. Plug this back in to the first equation to get x.

x + y = 180

x + 55 = 180

x = 125

Now that you have both, test them again just to be sure that they fit the given conditions.

What two numbers are located 1/2 of a unit from 1/6 on a number line?
ella [17]

Answer:

2/3 and -1/3

Step-by-step explanation:

We have to find which two numbers on the number line are at a distance of 1/2 from 1/6.

The two numbers that are 1/2 units away from 1/6 will be:

1) \frac{1}{6}+\frac{1}{2}\\\\ =\frac{1}{6}+\frac{3}{6}\\\\ =\frac{4}{6}\\\\=\frac{2}{3}

2) \frac{1}{6}-\frac{1}{2}\\\\ =\frac{1}{6}-\frac{3}{6}\\\\ =\frac{-2}{6}\\\\ =\frac{-1}{3}

Thus the two numbers are: 2/3 and -1/3
