Answer:
(x - 2 + i)(x - 2 - i)(x - 1)x^3 -5x^2 + 9x - 5Step-by-step explanation:
In order to have rational polynomial, it has to have 2 + i as third zero.
Polynomial in factored form:
(x - (2 - i))(x - (2 + i))(x - 1) =(x - 2 + i)(x - 2 - i)(x - 1)Polynomial in standard form:
(x^2 - 2x - ix - 2x + 4 +2i + ix - 2i -i^2)(x - 1) =(x^2 - 4x + 4 + 1)(x - 1) =(x^2 - 4x + 5)(x - 1) =x^3 - x^2 - 4x^2 + 4x + 5x - 5 =x^3 -5x^2 + 9x - 5The y-coordinate of the midpoint of a segment can be found by adding any two y-coordinates on the segment and dividing by two. True or False??

See below
Step-by-step explanation:
A > [tex]Sin^{2} x + cos^{2} x = 1 \\[/tex]
Divide both side by sin^2 x , and we get
[tex]\frac{sin^2 x}{sin^2 x} + \frac{cos^2 x}{ sin^2 x} = \frac{1}{sin^2 x}[/tex]
[tex]1+ cot^2 x= cosec^2 x[/tex]
Subtracting cosec^2 x from both sides we get
[tex]Cosec^2 x - cot^2 x = 1[/tex]
B>lets break tan θ into its components tan θ = sin θ / cos θ and cot θ = 1/ tan θ
Tan θ + cot θ= Sin θ/cos θ + cos θ/ sin θ = sin^2 θ + cos^2 θ / sin θ cos θ= 1/ sin θ cos θ = sec θ cosec θ

Kermit flipped a coin 20 times. The coin landed on tails six times. Which best describes what would likely happen if Kermit flipped the coin another 80 times?
Answers
Answer:
24 of those times would be tails.
Step-by-step explanation:
Because if you flip it 20 times and it lands on tails 6 times, you just have to add 20+20 6+6 so then it's 40 flips and 12 tails. 60 times and 18 tails 8p times and 24 tails.

What is the length of the shortest side if the perimeter of the rectangle is 56 inches?
Answers
Answer: Length of Shortest Side = 12 inches
Step-by-step explanation: Length of Shortest Side = L = 3x
Length of Longest Side = W = 5x-4
Condition:
2L+2W = Perimeter
2(3x)+2(5x-4) = 56
6x+10x-8 = 56
16x-8 = 56
Adding 8 to both sides
16x = 56+8
16x = 64
Dividing both sides by 14
=> x = 4
Now,
Length of the Shortest Side = L = 3(4) = 12 inches
Length of the Longest Side = W = 5(4)-4 = 16 inches
Calculate the value of x
Answers
Answer:
x = 55
Step-by-step explanation:
x + (2x+15) = 180
3x + 15 = 180
3x = 165
x = 55
Answer:
55°
Step-by-step explanation:
since angles in a straight line add up to 180°
x+2x+15=180°
3x+15=180°
3x=180-15
3x=165
divide by 3 on both sides
x=55°
