Answer:
The answer is 32.
Step-by-step explanation:
Complex numbers are the number that can be written in the form of a + b<em>i</em>, where a is the real part, b is the imaginary part and<em> </em><em>i </em>is the unit imaginary part which is equal to √-1.
<h3>Solving the given equation:</h3>
2x^x + p = 0
2x^2/2 + p/2 = 0/2
x^2 + p/2 = 0
x^2 +p/2 -p/2 = -p/2
x^2 = -p/2
taking √ on both sides
√x^2 =√(-p/2)
x = √(-1)(p/2)
as we know that √(-1) =<em> i</em>
therefore
x = √(p/2)<em>i</em>
Hence, form the given choices only 32 will gives the complex number as a solution.
Now putting p = 32, we'll get
x = √(32/2)<em>i</em>
x = 4<em>i</em> is the required solution.
Answer:
(m + 2 - x) (m + 2 + x)
Step-by-step explanation:
m² + 4m + 4 - x²
m² + 2(m)(2) + 2² - x²
(m + 2)² - x²
(m + 2 - x) (m + 2 + x)
B cause when you rotate 270 counter clockwise it ends up being lined up
Answer:
v=5.42m/s
Step-by-Step Explanation:
We can use conservation of energy to solve this
mgh=1/2mv^2
2gh=v^2
v=sqrt(2gh)
v=sqrt[2*9.8m/s^2*(6.5-5)]
v=5.42m/s
Answer:
5x-6+7x+12=180
Step-by-step explanation:
5x+7x = 12x
12x - 6 +12 = 180
add 12 and -6 to get 6.
12x + 6 = 180
subtract 6 from both sides to get 174.
12x = 174.
now divide both sides by 12 to get x = 14.5 or 29/2 which cancels out to 6
