Prove that there is no complex number such that | z | −z = i
The proof is shown below:
What is complex number?A complexb number is the of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z. Here both a and b are real numbers. The value 'a' is called the real part which is denoted by Re(z), and 'b' is called the imaginary part Im(z). Also, ib is called an imaginary number.
The alphabet i is referred to as the iota and is helpful to represent the imaginary part of the complex number. Further the iota(i) is very helpful to find the square root of negative numbers.
We know
z= a +ib
and |z|= √a² + b²
So, |z|-z =i
√a² + b² - a- ib=i
Now, comparing the coefficients
b=-1
√a² + b² - a = 0
√a² + (-1)² - a=0
√a² + 1 - a = 0
√a² + 1 = a
a² + 1 = a²
1= 0
Which is not possible.
Hence, there is no complex number such that | z | −z = i

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 402 gram setting. It is believed that the machine is underfilling the bags. A 23 bag sample had a mean of 400 grams with a variance of 900. A level of significance of 0.025 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answer:
Kindly check explanation
Step-by-step explanation:
H0 : μ ≥ 402
H1 : μ < 402
Test statistic :
n = 23
Sample Mean, x = 400
Variance = 900
σ = sqrt(900) = 30
Test statistic = (x - μ) ÷ σ/sqrt(n)
Test statistic = (400 - 402) ÷ 30/sqrt(23)
Test statistic = - 2 / 6.2554324
Test statistic = - 0.3197221
Test statistic = - 0.3197
Critical value :
Using the Tcritical value calculator
Tcrit; α = 0.025, df = n - 1 = 23 - 1 = 22
Tcritical = 2.074
Reject Null : if Test statistic ≤ Tcritical (left tail test)
Since ;
Test statistic ≤ Tcritical ; We reject the Null

Answer:
y=[(x-6)/5]^(1/3)+4
Step-by-step explanation:
f(x)=5(x-4)^3 +6
trade x and y
x=5(y-4)^3 +6
x-6=5(y-4)^3
(x-6)/5=(y-4)^3
[(x-6)/5]^(1/3)=y-4

Answer:
3(2 + 9)
Step-by-step explanation:
The numbers 6 and 27 can be written as factored as
6 = 2 * 3
27 = 3 * 3 * 3
The both have one factor of 3 in common.
The greatest common factor (the GCF) of 6 and 27 is 3.
Now we factor out 3. To do that, we divide both 6 and 27 by 3.
6/3 = 2
27/3 = 9
We see that
6 + 27 = 3 * 2 + 3 * 9,
and the common factor of 3 is in both multiplications.
Finally, we factor out the 3, leaving the results of the divisions inside the parentheses.
6 + 27 = 3 * 2 + 3 * 9 = 3(2 + 9)
Answer: 3(2 + 9)

A teacher is making 7 identical supply boxes
for each table in her classroom. Each box
contains some pencils and 11 pens. The
teacher uses a total of 182 pencils and pens.
Determine the number of pencils that are in
each box.
Answer:
26
Step-by-step explanation:
182 pencils devided by 7 identical boxes
182÷7
=26 pencils are in each box
Answer:
15 pencils in each box
Step-by-step explanation:
If each box has 11 pens,then there are 77 pens
In total 182 pencils and pens
182-77 = 105 (105 pencils)
105/7 = 15
15x7 = 105
11x7 = 77
105 +77 = 182

What is the domain of the function y = log(x + 3)?
O
(-00,00) (-00,00)
(-00, -3)
(0,co)
(-3,0)
DONE
Answer:
the domain for the function y=log(x+3) is (-3,oo).
The domain of the function y = log(x + 3) is (−3, +∞), or in interval notation, (−3, ∞).
The domain of the function y = log(x + 3) is the set of all possible values that x can take without making the expression undefined.
For the logarithmic function y = log(x), the argument of the logarithm (x in this case) must be greater than zero, otherwise the result is undefined.
So, to find the domain of y = log(x + 3), we need to solve the inequality x + 3 > 0, which gives x > -3.
Thus, the function y = log(x + 3) is (−3, +∞), or in interval notation, (−3, ∞) is the answer.

I have $460 less than dotun. Altogether we have $1280. How much do we have
Answer:
you have $180, total there is $1280
Step-by-step explanation:
The required amount we have is given as $410, as of the given condition.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
here,
Let the amount we and Dotun has to be x and y,
According to the question,
x = y - 460- - -- - -(1)
x + y = 1280 - - - (2)
From equation 1
y - 460 + y = 1280
2y = 1280 + 460
y = 1740/2
y = $870
Now,
x = 870 - 460
x = $410
Thus, the required amount we have is given as $410, as of the given condition.

3x - 2y = 7
4x + y = 2 then y = 2 - 4x
substitute for y:
3x - 2(2 - 4x) = 7
reduce:
3x - 4 + 8x = 7
11x = 11
x = 1
