There is no way to manipulate the number 20 to get the number 5908 by subtraction or any other arithmetic operation.

Therefore, "20-4=5908" is false.

The coordinate of the complex numbers are plotted on a graph below

i) Z₁ + Z₂ = (2+j4) + (3-j) = (2+3) + (j4-j) = 5 + j3

ii) Z₁ - Z₂ = (2+j4) - (3-j) = (2-3) + (j4+j) = -1 + j5

iii) Z₂ - Z₁ = (3-j) - (2+j4) = (3-2) + (-j-4j) = 1 - j5

iv) To represent these complex numbers on an Argand diagram, we plot the real part on the x-axis and the imaginary part on the y-axis.

Z₁ = 2 + j4 can be represented as a point in the complex plane with coordinates (2,4).

Z₂ = 3 - j can be represented as a point in the complex plane with coordinates (3,-1).

Using these coordinates, we can plot the results from parts (i) to (iii) as follows:

(i) Z₁ + Z₂ = 5 + j3 can be represented as a point in the complex plane with coordinates (5,3).

(ii) Z₁ - Z₂ = -1 + j5 can be represented as a point in the complex plane with coordinates (-1,5).

Answer: We can simplify the expression by using the identity for the tangent of half an angle:

tan(x/2) = sin(x) / (1 + cos(x))

where x is the angle in radians. We can use this identity by setting x = 56° since 2*28°= 56°.

So, we have:

sin(28°) / (1 + cos(28°)) = tan(56°/2)

We know that 56°/2 = 28°, so we have:

tan(28°)

Therefore, the expression simplifies to a single trigonometric function:

Suzie must pay $27,864 on delivery for the new truck. To determine how much Suzie must pay on delivery, we need to add the extra charges to the base price of the truck and subtract the down payment she already made.

Let's first list the extra charges:

Freight and PDI: $1,650

Air Tax: $100

Tire Tax: $20

GST (Goods and Services Tax): 5%

To calculate the extra charges, we can use the following formula:

Extra charges = Freight and PDI + Air Tax + Tire Tax + (GST x Base Price)

Substituting the given values, we get:

Extra charges = 1650 + 100 + 20 + (0.05 x 27280)

Extra charges = 1650 + 100 + 20 + 1364

Extra charges = 3134

Therefore, the total cost of the truck, including extra charges, is:

Total cost = Base price + Extra charges - Down payment

Total cost = 27280 + 3134 - 2450

Total cost = 27864

Thus, Suzie must pay $27,864 on delivery for the new truck.

It's important to note that the amount Suzie will actually pay will depend on the financing and payment options available to her. She may be able to spread out the payments over a longer period of time or negotiate a different down payment amount. It's always a good idea to research and compare different financing options before making a major purchase like a new vehicle.

The formula for the volume of a sphere is;

V = (4/3) * π * r^3

Where;

r = the radius of the sphere

Substituting the given value, we get;

r = 10

V = (4/3) * π * (10)^3

Step-by-step explanation:    The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run"

Answer: To obtain triangle A'B'C' from triangle ABC by reflection over the line y = 2, we reflect each point of the triangle over the line. This gives us:

A' = (A_x, 4 - A_y)

B' = (B_x, 4 - B_y)

C' = (C_x, 4 - C_y)

To obtain triangle A"B"C" from triangle A'B'C' by translation by the directed line segment from (0,0) to (3,2), we add the vector (3,2) to each point of the triangle. This gives us:

A" = (A'_x + 3, A'_y + 2) = (A_x + 3, 6 - A_y)

B" = (B'_x + 3, B'_y + 2) = (B_x + 3, 6 - B_y)

C" = (C'_x + 3, C'_y + 2) = (C_x + 3, 6 - C_y)

Therefore, the vertices of triangle A"B"C" are (A_x + 3, 6 - A_y), (B_x + 3, 6 - B_y), and (C_x + 3, 6 - C_y).

The relationship between the lines are they have same slope and they are parallel.

What is slope?

If [tex](x_1,y_1) \: and \: (x_2,y_2) [/tex] are two points on line then slope of the line will be [tex]m= \frac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]

To determine the relationship between the two lines, we need to find out if they are parallel, perpendicular, or neither.

First, we can find the slope of the line passing through (7,1) and (10,5) using the slope formula:

[tex]m_1 = \frac{(y_2 - y_1)}{(x_2 - x_1)} \\ m_1 = \frac{ (5 - 1)}{(10 - 7)} \\ m_1 = \frac{4}{3} [/tex]

Similarly, we can find the slope of the line passing through (-8,5) and (-5,9):

[tex]m_2 = \frac{ (y_2 - y_1) }{ (x_2 - x_1)} \\ m_2 = \frac{(9 - 5) }{(-5 - (-8))} \\ m_2 = \frac{4}{3} [/tex]

Since both lines have the same slope of 4/3, they are parallel to each other.

The final answer for linearizing the function f(x) = cos^5(x) around a = 0 is:

f(x) ≈ 1.

Linearizing a function is the process of approximating the behavior of a function by a linear function (i.e., a function of the form y = mx + b) in a certain region around a specific point.

Linearization is useful because linear functions are easy to work with mathematically, and they can provide a good approximation of the original function near the point of interest. By linearizing a function, we can simplify calculations and make predictions about the behavior of the function in the vicinity of the point of interest.

In the given question,

To linearize the function f(x) = cos^5(x) around a point a, we can use the first two terms of the Taylor series expansion:

f(x) ≈ f(a) + f'(a)(x - a)

where f'(a) is the first derivative of f evaluated at x = a.

In this case, we want to linearize around a = 0, so we have:

f(x) ≈ f(0) + f'(0)(x - 0)

To find f(0) and f'(0), we need to evaluate the function and its derivative at x = 0:

f(x) = cos^5(x)

f(0) = cos^5(0) = 1

f'(x) = 5cos^4(x)(-sin(x))

f'(0) = 5cos^4(0)(-sin(0)) = 0

Therefore, the linearization of f(x) = cos^5(x) around a = 0 is:

f(x) ≈ 1 + 0(x - 0) = 1

So the linearization is simply the constant function f(x) = 1. This means that for small values of x, the function cos^5(x) can be approximated by the constant function 1. The accuracy of this approximation depends on how small x is and how far away x is from 0.

the total cost of leather purchased to make the football is $30.79.

The volume of a football can be calculated using the formula for the volume of a sphere:

V = (4/3)πr³

Where r is the radius

Given that the diameter of the football is 14 cm and  the radius is half of the diameter, so radius is 7 cm.

So, the volume of the football is:

V = (4/3)π(7 cm)³

= 1437.33 cm³

Now, we know that 3% of the leather is wasted,

so the amount of leather to make the football is:

(100% - 3%) = 97% of the total leather purchased.

Therefore, the amount of leather used to make the football is:

0.97 × 1437.33 cm³ = 1394.19 cm³

To find the total cost of the leather purchased, we need to know the cost of leather per square centimeter. Let's assume that the cost of leather including labor is $0.05 per square centimeter.

The surface area of a sphere can be calculated using the formula:

A = 4πr²

So, the surface area of the football is:

A = 4π(7 cm)²

= 615.75 cm²

the total cost of the leather:

Cost of leather = Cost per square centimeter × Surface area of the football

= $0.05/cm² × 615.75 cm²

= $30.79
