Answer: [tex]10\left(\cos90^{\circ}+i\sin90^{\circ}\right)[/tex]
Step-by-step explanation:
Given
The complex number is [tex]z_1=0+10i[/tex]
Complex number in polar form is given by
[tex]z=r\left(\cos \theta +i\sin \theta\right)[/tex]
Compare it with the given complex number
[tex]r=10[/tex] and [tex]\sin \theta=1[/tex] which implies [tex]\theta[/tex] must be [tex]90^{\circ}[/tex]
So, in the polar form, it is
[tex]z_1=10\left(\cos90^{\circ}+i\sin90^{\circ}\right)\\z_1=10e^{i\frac{\pi}{2}}[/tex]

Answer:
The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

To find the solution to a system of linear equations, Verdita begins by creating equations for the two sets of data points below.
Data Set A
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 1, 1, 5, 7. Column 2 is labeled y with entries negative 6, 2, 18, 26.
Data Set B
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 5, negative 2, 0, 6. Column 2 is labeled y with entries negative 1, 2, 4, 10.
Which equations could Verdita use to represent the data sets?
Data Set A: y = 4 x minus 2
Data Set B: y = x + 4
Data Set A: y = 4 x minus 2
Data Set B: y = x minus 4
Data Set A: y = 4 x + 2
Data Set B: y = x minus 4
Data Set A: y = 4 x + 2
Data Set B: y = x + 4
Answers
Answer:
The answer to this question would be A Data Set A: y = 4x - 2 Data Set B: y = x + 4

The value of both the logarithmic expressions is equal which is equal to the negative one.
What is a logarithm?Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.
The expressions are given below.
[tex]\log _3 \dfrac{1}{3} \ and \ \log _b \dfrac{1}{b}[/tex]
This can be written as
[tex]\log _3 3^{-1} \\\\\log _bb^{-1}[/tex]
We know that the property of the logarithm
[tex]\log _a a = 1\\\\\log a^b = b\log a[/tex]
Then we have
[tex]\log _3 3^{-1} = -1 \log _33 = -1\\\\\log _bb^{-1} = -1 \log _bb = -1\\[/tex]
The value of both the expressions is equal which is equal to the negative one.

The manager of a cafeteria kept track of the number of each type of lunch sold in October and made this table. Which graph
best correctly and completely represents the data in the table?
Answers
Answer:
The third one.
Step-by-step explanation:
The first graph says each square is 10 lunches, but there are only 3 squares for the deli sandwich. That's 30 deli sandwiches in total but there were 300 in the table so the first one is wrong. In the second one, it says that 2 types of lunches were sold up to 300 times, but in the table, only 1 was. The last graph says that there were 300 pizzas sold, but the table said there were 650, so that one is wrong.
Process of elimination leaves you with the third graph as the correct answer.
