Difference of Squares gives which complex factors for the expression x2 +3?
Andreas93 [3]

Step-by-step explanation:

Shortest way to solve this question is to find the factors of the given expression.

The given expression is (x² + 13).

Now we have to factorize it.

(x² + 13) = x² + (√13)²

            = x² + [-(i)²√(13)²]  [Since i = √(-1)]

            = x² - (i√13)²

            = (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]-by-

You are standing on top of a building looking down at your friend who is getting chased by a zombie. The building is 150 feet ta
Naddika [18.5K]

Answer:

a) 125.865 ft

b) 321.676 ft

c) 195.811 ft

Step-by-step explanation:

Given:-

- The height of the building, H = 150 ft

- The angle of elevation ( friend - top of building ), θ1 = 50°

- The angle of elevation ( zombie - top of building ), θ2 = 25°

Find:-

a) How far away is your friend from the building

b) How far away is the zombie from the building

c) How far away is the zombie from your friend

Solution:-

- We will consider the two right angle triangles with similar height ( H ) which denotes the height of the building.

- The distance your friend is from the building is ( x1 ) and looks up to the top of the building with angle of elevation of ( θ1 ).

- We can apply the trigonometric ratio for the right angle triangle formed between your friend, foot of the building and you ( on top of the building ):

                    tan ( θ1 ) = H / x1

                    x1 = H / tan ( θ1 )

                    x1 = 150 / tan ( 50° )

                    x1 = 125.865 ft    ... Answer ( a )

- The distance zombie is from the building is ( x2 ) and looks up to the top of the building with angle of elevation of ( θ2 ).

- Similarly, apply the appropriate trigonometric ratio for the right angle triangle formed between zombie, foot of the building and you ( on top of the building ):

                    tan ( θ2 ) = H / x2

                    x2 = H / tan ( θ2 )

                    x2 = 150 / tan ( 25° )

                    x2 = 321.676 ft    ... Answer ( b )    

- The distance between your friend and the zombie ( s ) can now be determined from subtracting the distance of your friend from the building from distance of the zombie from the building:

                    s = x2 - x1

                    s = 321.676 - 125.865

                    s =  195.811 ft    ... Answer ( c )

y = 3x + 1

The ? is 3

Enter the numbers into the equation:

Enter (0,1) --> 1 = 0 + 1 --> 1 = 1

Enter (3,10) --> 10 = 3 · 3 + 1 --> 10 = 9 + 1 --> 10 = 10
