The distance between the helicopter and the first home is 369. 87 m

<h3>How to solve the distance using the angle of depression?</h3>

The distance between the helicopter and the first home can be found using sine law,

Hence,

180 - 72 - 49 = 59 degrees.

Therefore,

420 / sin 59 = A / sin 49°

where

  • A  = distance form the first home to the helicopter.

cross multiply

420 sin 49 = A sin 59°

A = 420 sin 49 / sin 59

A = 316.978023694 / 0.8571673007

A = 369.869339199

A = 369. 87 m

Therefore, the distance between the helicopter and the first home is 369. 87 m

Select the correct answer. What is the difference of the values of the two variables in this system of equations? Y = 2x + 1 x +
zzz [600]

Answer:

Option C. 2

Step-by-step explanation:

we have

y=2x+1 -----> equation A

x+3y=10 -----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (1,3)

see the attached figure

therefore

The solution of the system of equations is

x=1,y=3

Find the difference

y-x=3-1=2

Find the sum. express your answer in simplest form 8m^2-6/n+3 + 9m^2-4/n+3
Alex787 [66]
To solve this problem you must apply the proccedure shown below:

 1. You have the following expressions shown in the problem above:

 (<span>8m^2-6/n+3) + (9m^2-4/n+3)

 2. As you can see, they have equal denominators, then you have:

 (</span><span>8m^2-6+ 9m^2-4)/(n+3)
</span><span>
 3. Therefore, when you sum, you have the following result:

 (17m</span>²-10)/(n+3)
<span>
 The answer is: </span> (17m²-10)/(n+3)<span>

Okay, So To Find The Mean, We Need To Look At The Values.
-588,-838,-691,-818,-846,-725,-605,-732,<span>-750
</span>So, We Add Them, Then Divide.
-588+-838+-691+-818+-846+-725+-605+-732+-750
---------------------------------------------------------------------
                                      9
This Is -732.555556.Rounded Is -733
Now, The Median. The Middle Value. 
The Middle Value Is -846.
So, The Mean Is A, 113 Points Higher.
