The complex number Z= 1-(3 can also be written as?
Answers
Given the Complex Number:
\(z=1-i\sqrt{3}\)You can identify that it is written in Rectangular Form:
\(z=x+yi\)By definition, the coordinates in Rectangular Form are:
\((x,y)\)And in Polar Form:
\((r,\theta)\)In this case, you can identify that:
\(\begin{gathered} x=1 \\ y=\sqrt{3} \end{gathered}\)In order to convert them to Polar Form, you need to use these formulas:
\(\begin{gathered} x=r\cdot cos\theta \\ y=r\cdot sin\theta \end{gathered}\)Use this formula to find "r":
\(r=\sqrt{x^2+y^2}\)Then, this is:
\(r=\sqrt{1^2+(\sqrt{3})^2}=2\)You need to find the angle. You can use this formula:
\(\theta=tan^{-1}(\frac{y}{x})\)Therefore the angle is:
\(\theta=tan^{-1}(-\sqrt{3})+360\text{ \degree}\)\(\theta=300°\)Then:
\(z=2cos300\text{\degree}+2isin300\text{\degree}\)Hence, the answer is: Last option.

Suppose A and B are independent events. The probability that event A will not occur is 0.1 and the probability that event B will occur is 0.7. Find P(A), P(not B) and P(A and B).
Answers
Answer:
The probability for A is 1-0.1 is 90%
P(A)=90%
P(NOT B)=30%
P(A AND B)=0.9+0.7/2=1.6/2=80%
p(a and b) may be a little off.
Answers:
P(A) = 0.9P(not B) = 0.3P(A and B) = 0.63=======================================================
Work Shown:
P(A) = 1 - P(not A)
P(A) = 1 - 0.1
P(A) = 0.9
-------------------
P(not B) = 1 - P(B)
P(not B) = 1 -0.7
P(not B) = 0.3
-------------------
P(A and B) = P(A)*P(B) only when A and B are independent
P(A and B) = 0.9*0.7
P(A and B) = 0.63

How long does it take for an investment of $6,400 to increase to $14,000 if
it is invested at 5% per year compounded continuously? Round to the
nearest tenth of a year.
Answers
An investment of $6,400 to increase to $14,000 if it is invested at 5% per year compounded continuously is ≈15.6
Define compound interest?
Compound interest is the interest imposed on a loan or deposit amount. It is the most commonly used concept in our daily existence. The compound interest for an amount depends on both Principal and interest gained over periods.Given that :
P = $ 6,400
Q = $ 14,000
r = 5%
Let P be the initial investment
r be the rate of interest
t be the time
Q be the increase amount
Q = P \(e^{rt} }\)
14,000 = 6,400 (\(e^{0.05t}\))
\(e^{0.05t}\) = \(\frac{14000}{6400}\)
\(e^{0.05t}\) = 2.187
Taking log on both sides , we get
0.05t = ln (2.187)
0.05t = 0.78
t = \(\frac{0.78}{0.05}\)
t ≈ 15.6
An investment of $6,400 to increase to $14,000 if it is invested at 5% per year compounded continuously is ≈ 15.6

12. A plot of land is used to grow flowers. of the land is allocated for orchids. 2 After the orchids have been planted, of the remaining land is allocated for roses. After orchids and roses have been planted, 0.75 of the remaining land is allocated for tulips. What fraction of the plot of land is not occupied by the flowers?
Answers
The fraction of the plot of land not occupied by the flowers is 0.0625 or 1/16.
Let's calculate the fraction of the plot of land that is not occupied by the flowers.
Given that initially, 1/4 of the land is allocated for orchids, we have 1 - 1/4 = 3/4 of the land remaining.
After planting the orchids, 2/3 of the remaining land is allocated for roses. Therefore, the fraction of land allocated for roses is (2/3) * (3/4) = 2/4 = 1/2.
Subtracting the land allocated for roses from the remaining land, we have 3/4 - 1/2 = 1/4 of the land remaining.
Finally, 0.75 of the remaining land is allocated for tulips. Therefore, the fraction of land allocated for tulips is 0.75 * (1/4) = 0.1875.
To find the fraction of the plot of land not occupied by the flowers, we subtract the fractions of land allocated for flowers from 1:
1 - (1/4 + 1/2 + 0.1875) = 1 - 0.9375 = 0.0625.
Therefore, the fraction of the plot of land not occupied by the flowers is 0.0625.

A first number plus twice a second number is 4. Twice the first number plus the second totals 17. Find the numbers
Answers
Answer:
10; -3
Step-by-step explanation:
Let's represent the first number with x, and the second number with y. Now let's write these two equations to find the numbers.
x + 2y = 4
2x + y = 17
We can solve using the substitution method:
x = 4 - 2y
2x + y = 17
2 (4 - 2y) + y = 17
8 - 4y + y = 17
-3y = 9
y = -3
Now plug the value of y in to find x:
x + 2y = 4
x + 2(-3) = 4
x + -6 = 4
x = 10
So, the first number is 10, and the second number is -3.

What is a system of linear inequalities?
At least two linear inequalities in the same variables make up a system of a linear inequality in two variables. The graph of a linear inequality is the graph of all solutions to the system, and the solution of a linear inequality is the ordered pair that resolves all inequalities in the system.
Here, we have
Given inequalities
-4x+3y<15 and -6x-4y<12
Now we solve the system of linear inequalities
For, -4x+3y<15
When we put x= 0, we get
y = 5
and if we put y = 0 , we get
x = -15/4
For, -6x-4y<12
When we put x= 0, we get
y = -3
and if we put y = 0 , we get
x = -2
