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:
63
Step-by-step explanation:
The number of seats in a row will give an arithmetic sequence:
6, 9, 12, 15, ...
The first term is 6; the common difference is 3. The general term is ...
an = a1 +d(n -1) . . . . . . n-th term of sequence with first term a1, difference d
The 20th term of the sequence is ...
a20 = 6 +3(20 -1) = 6 +57 = 63
There would be 63 seats on the 20th row.
Your answer would be 0.2x + 7.5
Hey, there batgirl177! :)
The formula for the area of a rectangle is:
Lets input the information we know:
The area would be
Rounding to significant digits:Rounding to the first significant digit gives you 30
Rounding to the second significant digit gives you 38
Rounding to the third significant digit gives you 38.3
Rounding to the fourth significant digit gives you 38.25
Hope this helps.

Answer:
592 hours
Step-by-step explanation:
Given
Required
Determine the time taken to cover the area
Since, the oil formed a circular pattern; the question will be answered using area of a circle
Let t represent the time take to cover 11000m²;
The relationship between these parameters is:
Substitute 3.14 for π
Divide both sides by 3.14
Take square root of both sides
Divide both sides by 0.10
<em>(</em><em>Approximated)</em>
<em>Hence, it'll take approximately 592 hours to cover the given area</em>
