What are complex numbers?Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfies the equation i² = 1.
The given number is 18. The number in the form of a complex number can be written as:-
Complex number = a + bi
Complex number = 18 + 0i
Therefore, the number 18 in the form of complex numbers will be written as 18 + 0i.

A teacher chooses two students in a class of 15 girls and 10 boys. The students are randomly chosen. What is the probability that the teacher chooses two girls?
1. 3/5
2. 3/7
3. 7/12
4. 7/20
Answer:
15/25 which simplifies to 3/5 which is the first answer
Step-by-step explanation:
The table shows a set of values for x and y
a) Assume y = [tex]x^{2}[/tex]
[tex]1b=\frac{k}{1^{2} }[/tex] k = 1b
[tex]y=\frac{1b}{x^{2} }[/tex]
b) y = 25
[tex]x^{2}=\frac{16}{25}[/tex]
[tex]x=\sqrt{\frac{4}{5} ^{2} }[/tex]
x = ±[tex]\frac{4}{5}[/tex]
x > 0, x = 4/5
{ Equation }
y=16/x² is required equation for y in terms of x and x=4/5 when y=25.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The table of values are
x 1 2 3 4
y 16 4 16/9 1
Given that y is inversely proportional to square of x.
y=k/x²
Let us consider
y=16 and x=1
16=k/1
k=16.
y=16/x²
So y=16/x² is equation for y in terms of x
b) We need to find value of x when y=25
25=16/x²
Use cross multiplication
x²=16/25
Take square root on both sides
√x²=√16/25
x=±4/5
If x>0 , so x=4/5
Hence y=16/x² is required equation for y in terms of x and x=4/5 when y=25.

A.) Write explicit rule for sequence
B.) Write recursive rule for sequence.
Answer:It's an arithmetic sequence with a common difference, d, = 4
A1 = 8
A2 = 8+4 = 12
A3 = 12+4 = 16 = 8+4(3-1) = 8+4(2) = 8+8
AN = A1 + d(N-1)
AN = 8 +4(N-1) = the Nth term in the sequence

Working simultaneously, four fudge machines complete a big order in 32 hours. All the machines at the fudge factory work at the same pace. How many hours would it take to complete the order with twice the number of working machines?
Answer:
4 Hours
Step-by-step explanation:
Let's say that the rate of the machines 1/x, because every time they complete an order, it takes them x hours. To find x, we have to add the the rates of the individual machines, which would equal the rate of the machines working together. We know that there are four machines working together at the same rate, and it took them 32 hours.
So:
1/x + 1/x + 1/x + 1/x = 1/32
1/4x = 1/32
4x = 32
x = 8
Thus, the rate of the machines is 1/8.
Now we have to find the time of the order with only half of the machines working together. This time, we don't know the combined rate, so I'll substitute it for y.
1/8 + 1/8 = 1/y
1/4 = 1/y
y = 4
The time taken to complete it is 4 hours.

Answer:
After , the sequence repeats itself
Divide 37/4 = 9 R 1. Now use the remainder and find which one of the values of i it matches.
so
Step-by-step explanation:
The expressions are simplified as;
i. t = ∛i
ii. t = 1
How to simply the expressionsFrom the information given, we have that;
Simplifying [tex]t^3^7[/tex] = √i
When [tex]t^3^7[/tex]equals i (the imaginary unit), we can solve for "t" by taking the 37th root of both sides:
[tex]t^3^7 = i[/tex]
[tex]t = \sqrt[3]{i^3^7}[/tex]
[tex]t = i^(^3^7^/^3^)[/tex]
Since i^4 = 1 (i raised to the power of 4 is 1), we can simplify the exponent:
[tex]t = i^(^1^2 ^+ ^1^/^3^)[/tex]
[tex]t = i^1^2 ^* i^(^1^/^3^)[/tex]
Now, since[tex]i^1^2[/tex] = 1 and [tex]i^(^1^/^3^)[/tex] represents the cube root of i, we have:
t = 1 * ∛i
t = ∛i
Simplifying [tex]t^8^2[/tex] = √ –1:
Take the 82nd root of -1
[tex]t^8^2 = -1[/tex]
t = [tex]\sqrt{(-1)^8^2}[/tex]
t = √1
t = 1

Look at the 5th digit after the decimal place. If it is a 4 or lower, round down. If it is a 5 or higher, round up:
11.03656 - 6 is higher than 5 so the number is rounded up to 11.0366
Hope this helps!
The number is rounded up to 11.0366.
How to identify the place value of a digit in a number?The place values on left of decimal point start as ones, tens, hundreds, and so on...
The place value on right of decimal point starts from point and goes to right as tenths, hundreths and so on..
Thus, The tens means multiply by 10
Thus, The tenth means tenth part of that digit which is that digit divided by 10
If we Look at the 5th digit after the decimal place. it is a 4 or lower, round down. If it is a 5 or higher, round up:
11.03656 -
