Which addition expression has the sum 8 – 3i ?
(9 + 2i) + (1 – i)
(9 + 4i) + (–1 – 7i)
(7 + 2i) + (1 – i)
(7 + 4i) + (–1 – 7i)
The expression of (9 + 4i) + (–1 – 7i) has the sum (8 – 3i) which correct option(B).
What is complex number?A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, b are real numbers and i is an imaginary number.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation : Divides left hand operand by right hand operand
For example 4/2 = 2
(B) (9 + 4i) + (–1 – 7i)
⇒ (9 + 4i) + (–1 – 7i)
⇒ 9 + 4i –1 – 7i
Rearrange the terms like wise and apply arithmetic operations
⇒ 9 - 1 + 4i - 7i
⇒ 8 – 3i
Hence, the expression of (9 + 4i) + (–1 – 7i) has the sum (8 – 3i).

Step-by-step explanation:
Gavin goes to the market and buys one rectangle shaped board. The length of the board is 16 cm and width is 10 cm. if he wants to add a 2 cm wooden border around the board, what will be the area of the rectangle board?
The area of the rectangle board, including the wooden border, is 280 cm².
The student's question pertains to finding the new area of the rectangle board after adding a 2 cm wooden border around it. Initially, the board has dimensions of 16 cm in length and 10 cm in width. To account for the new wooden border, we add 2 cm to each side of the board. This means that the new length will be 16 cm + 4 cm (2 cm for each side of the length) and the new width will be 10 cm + 4 cm (2 cm for each side of the width).
The calculation will be as follows:
New Length = 16 cm + 4 cm = 20 cm
New Width = 10 cm + 4 cm = 14 cm
Area = New Length * New Width
Area = 20 cm * 14 cm
Area = 280 cm²
Therefore, the area of the rectangle board with a 2 cm border added around it will be 280 cm².

Kaia needs braces, which will cost $2,400. Her insurance deductible is $1500, after which her insurance pays 80% of all costs. How much will Kaia need to pay for her braces?
A.$2,200
B.$1,680
C.$180
D.$480
Kaia will pay a $1,500 deductible and the remaining 20% not covered by insurance after the deductible, totaling to $1,680 for her braces.
To calculate how much Kaia will need to pay for her braces, we need to take into account her insurance deductible and the percentage her insurance will cover after that deductible is paid. Kaia's braces cost $2,400, so let's break it down step-by-step:
Kaia pays her insurance deductible, which is $1,500. So, $2,400 - $1,500 = $900 remains.
Her insurance then covers 80% of the remaining $900. To calculate this, we use 80% of $900: ($900 x 0.80) = $720.
Since the insurance pays $720 of the remaining cost, Kaia is left with 20% of $900 to pay out of her pocket. To calculate this, we take 20% of $900: ($900 x 0.20) = $180.
Therefore, Kaia will need to pay $1,500 (deductible) plus $180, for a total of $1,680.
Which of the following graphs represent a function? 4072-01-02-01- a. Graph A and Graph C b. Graph A c. Graph D d. Graph B and Graph D
The graph which represent a graph of a function is:
Graph A and Graph C
Step-by-step explanation:We know that a graph of a function satisfies the vertical line test i.e. any line passing through the domain and parallel to y-axis should intersect the curve exactly once i.e. corresponding to each x-value there is exactly one y-value.
Hence, from the figure attached to the answer we see that the Graph which is a function is:
Graph A and Graph C
Graph A represents a function.
Explanation:A function is a relation in which each input has only one output. In other words, for every x-value, there can only be one y-value. To determine if a graph represents a function, we can use the vertical line test. If a vertical line intersects the graph at more than one point, then the graph does not represent a function. Looking at the given graphs, Graph B and Graph D do not pass the vertical line test, as there are vertical lines that intersect these graphs at multiple points. Therefore, the correct answer is Graph A.

The calculated coordinates of the point P is P (-3/2, -3/2)
How to determine the coordinates of the point PFrom the question, we have the following parameters that can be used in our computation:
A = (1, 6)
Also, we have
B = (-2, -3)
And we have the partition to be
m : n = 5 : 1
The coordinate of the partition is calculated as
P = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)
Substitute the known values in the above equation, so, we have the following representation
P = 1/(5 + 1) * (5 * -2 + 1 * 1, 5 * -3 + 1 * 6)
This gives
P = 1/6 * (-9, -9)
So, we have
P = (-3/2, -3/2)
Hence, the coordinate is P = (-3/2, -3/2)

To find the coordinates of point P along the directed line segment AB, we can use the concept of section formula and plug in the given values to find the coordinates (-3/2, -3/2).
Explanation:To find the coordinates of point P along the directed line segment AB, we can use the concept of section formula. The section formula states that if a point P divides a line segment AB in the ratio m:n, then the coordinates of P can be found using the formula:
P(x,y) = [(mx2 + nx1)/(m+n), (my2 + ny1)/(m+n)]
Using this formula, we can plug in the values: m=5, n=1, x1=1, y1=6, x2=-2, y2=-3 to find the coordinates of point P.
P(x,y) = [(5*(-2) + 1*1)/(5+1), (5*(-3) + 1*6)/(5+1)] = [(-10+1)/6, (-15+6)/6] = [-9/6, -9/6] = (-3/2, -3/2)

The amount of Honey produced by 1000 hives is the multiplication of 1000 to 85 thus 85000 pounds will be produced.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.
As per the given question,
Larson's Honey Farm usually produces 85 pounds of honey per year.
If one family is producing 85 pounds of honey per year then,
1000 hives will produce ⇒ 85 × 1000 = 85000 pounds.
Hence "The amount of Honey produced by 1000 hives is the multiplication of 1000 to 85 thus 85000 pounds will be produced".

a metalworker has a metal alloy that is 15% copper and another alloy that is 55% copper. how many kilograms of each alloy should the metalworker combine to create 90kg of a 47% copper alloy
x = amount at 15%
90-x = amount of 55%
0.15x + 0.55(90-x) = 0.47(90)
0.15x +49.5 - 0.55x = 42.3
49.5 - 0.40x = 42.3
-0.40x = -7.2
x = -7.2 / -0.4 = 18 kg of 15% copper
90-18 = 72 kg of 55% copper
What construction does the image below demonstrate?
Answer:
The construction depicts the inscribing of a hexagon in a circle.
Step-by-step explanation:
These are the following steps to inscribe a hexagon in a circle.
1. We mark a point anywhere on the circle. This mark is the first vertex of the hexagon.
2. Now we will set the compass on this vertex and set the width to the center of the circle. This is the radius of the circle.
3. Now we will make an arc across the circle which is the next vertex of the hexagon.
4. Now moving the compass on to the next vertex and drawing another arc, which becomes the third vertex of the hexagon.
5. Repeat step 4 until all vertices are marked.
6. Lastly, we will draw a line between each successive pairs of vertices, for a total of six lines.
Now we can see a hexagon inscribed in a circle.
