review the graph. given a pair of complex numbers, z1=5 and z2=-6i, let z3=3i+z1 and z4=z2-2. In which quadrant is z3-z4 located?
A. Quadrant 1
B. Quadrant 2
C. Quadrant 3
D. Quadrant 4
Answers
Answer:
A
Step-by-step explanation:
z₃ - z₄ is located in Quadrant 1, the correct option is A.
What are complex numbers?The numbers that can be expressed in the form of a + ib are called Complex numbers, i is called the iota, whose value is equal to the square root of -1.
These are imaginary numbers.
The complex numbers are
z₁ = 5
z₂ = -6i
z₃ = 3i +z₁
z₃ = 3i + 5
z₄ = z₂ - 2
z₄ = -6i -2
The mathematical operations in all the complex numbers are performed similarly in real numbers,
The like terms are grouped together.
The subtraction of the complex numbers has to be determined.
z₃ - z₄ = ( 3i + 5) - ( -6i -2)
z₃ - z₄ = 3i +6i +5 +2
z₃ - z₄ = 9i +7
The constant and the imaginary term depict the x and y coordinate respectively.
As both the terms are positive, it lies in Quadrant 1.

In the accompanying diagram ab is tangent to circle O at B and ACD is a secant.
If AB=9 and AD=27, find AC
Answers
Answer:
AC = 3
Step-by-step explanation:
Based on tangent and secant theorem, thus:
AB² = AC × (AC + CD)
AB = 9
AD = AC + CD = 27
Plug in the values
9² = AC × (27)
81 = AC × 27
Divide both sides by 27
81/27 = AC
3 = AC
AC = 3

A store is randomly giving away gift cards to the first 150 customers. They are giving 130 gift cards that have a value of $5 each and 15 gift cards that have a value of $50 each. The rest of the gift cards have a value of $100 each. Which is the probability that a customer will get a $100 gift card?
Answers
Answer:
1/30
Step-by-step explanation:
The total number of cards is 150. Subtract the numbers of the other values, 130 and 15 to get the number of $100 cards.
150 -145 = 5
5/150 is the number out of the total.
Simplify to get the probability: 1/30

What is the area of this figura?
Answers
Answer:
total area of the figure is: 1568 yd^2
Step-by-step explanation:
The area of the figure is the addition of the areas of a square and a rectangle:
The square on top that measures 28 yd times 28 yd, therefore its area is:
28^2 yd^2 = 784 yd^2
The rectangle at the bottom measures: 56 yd times 14 yd, therefore its area is:
Area rectangle = base x height = 56 yd x 14 yd = 784 yd^2
Then, the total area is the addition of these two:
Area of square + area of rectangle = 784 yd^2 + 784 yd^2 = 1568 yd^2

Sophia uses 3 3/4 cups of flour for each cake she makes. She has a 10-pound bag of flour that costs $8.79 and contains 152 quarter-cup servings.
Question 1
Part A
How many cakes can Sophia make with this flour?
Answers
The number of cakes Sophia can make is 10.
The bag of flour contains 152 quarter-cup servings. So, the quantity in t he bag has to be divided by four.
Number of cups = 152 / 4 = 38 cups
In order to determine the number of cakes she can make, divide the number of cups in the bag by the cups needed to make one cake.
38 ÷ 3 3/4
38 ÷ 15/4
38 × 4/15 = 10.1 cakes
To learn more about division, please check: https://brainly.com/question/808272
Sophia will be able to make 10 cakes with this amount of flour.
Since Sophia uses 3 3/4 cups of flour for each cake she makes, and she has a 10-pound bag of flour that costs $ 8.79 and contains 152 quarter-cup servings, to determine how many cakes can Sophia make with this flour you must perform the following calculation:
3/4 = 0.75 (152/4) / 3.75 = X 38 / 3.75 = X 10.13 = X
Therefore, Sophia will be able to make 10 cakes with this amount of flour.
