Answer:

See the attached figure

Given:

-3x + 2y = 8

5x + 2y = -8

To graph the given equation, make a table between x and y for each equation

Assume x then find the value of y

as an example:

for the equation -3x + 2y = 8

Let x = 0 so, y = 8/2 = 4 and so on

Then graph the pair (x,y), connect the points to graph the line

The attached figure represents the graph of the both line and the table for each line required to graph it.

Also, the intersection between the lines.

Write the following sets in set-builder notation: (a) The set of all humans whose first name is Tanya or Nelson.

Ulleksa [173]

Answer:

Step-by-step explanation:

Set is a well defined collection of objects .

We can express set in roaster form or set - builder form

Roaster Form

We express elements within curly brackets using commas between the elements .

Set Builder Form

In set builder form , all the elements of the set possess a common property which is not possess by elements outside the set .

We describe the elements of set using a symbol x which is followed by a colon . After colon , we write property possessed by the element and then enclosed the description within curly brackets .

(a)The set of all humans whose first name is Tanya or Nelson

We need to write this one in set builder form .

Define set as follows : { x ∈ H : H is set of all the humans and x is either Tanya or Nelson }

From a radar station, the angle of elevation of an approaching airplane is 32.5 degree. The horizontal distance between the plan

denis23 [38]

Answer: 42.21 km

Step-by-step explanation:

We can solve this using trigonometry, since we have the following data:

$\theta=32.5\°$ is the the angle of elevation

$d=35.6 km$ is the horizontal distance between the plane and the radar station

$x$ is the hypotenuse of the right triangle formed between the radar station and the airplane

Now, the trigonometric function that will be used is cosine:

$cos\theta=\frac{d}{x}$ because $d$ is the adjacent side of the right triangle

$cos(32.5\°)=\frac{35.6 km}{x}$

Finding $x$ :

$x=\frac{35.6 km}{cos(32.5\°)}$

$x=42.21 km$
