Imhotep can pain the pyramid in 256 different ways, and his assistant can make 64 different models of the pyramid, as explained below.
How to pain the pyramid:There are 4 sides to paint, and each side can be painted with one of 4 colors. So the total number of different ways Imhotep can paint the Great Pyramid is:
4 x 4 x 4 x 4 = 256
Therefore, Imhotep can paint the Great Pyramid in 256 different ways. However, as pointed out, many of these ways are just rotations of each other. Specifically, there are 4 different rotations for each way of painting the pyramid. Therefore, the number of distinct models can be seen below:
256 / 4 = 64
Therefore, Imhotep's assistant only needs to make 64 different models.
The complete question is the following:
Imhotep the architect wants to paint the Great Pyramid. He wants one red side, one blue side, one green side and one yellow side. How many different ways can he paint it?His assistant is tasked with making models to show the possibilities. He realises he can make far fewer models as they can be turned around.

Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88 × 1012 miles. Suppose a star is 9.8 × 101 light-years from Earth. In scientific notation, approximately how many miles is it? (1 point) 5.88 × 1013 miles 5.76 × 1014 miles 5.88 × 1012 miles 9.8 × 1012 miles
The correct answer is 5.88 × 1013 miles. This is because a light-year is the distance that light can travel in one year, or approximately 5.88 × 1012 miles.
What is a light year?A light year is a unit of distance used to measure astronomical distances. It is the distance that light travels in a vacuum in one year, which is equal to 9.46 trillion kilometres. This means that light travelling at a speed of 300,000 kilometres per second would take one year to travel nine trillion kilometres. T
To find the distance of a star from Earth, one must multiply the number of light-years by 5.88 × 1012. In this case, the star is 9.8 × 101 light-years away, meaning that it is 9.8 × 101 times 5.88 × 1012 miles, or 5.88 × 1013 miles, away from Earth.
Light-years are a unit of distance used by astronomers to measure the great distances between stars and galaxies. Light travels at a speed of approximately 186,000 miles per second, and one light-year is the distance that light can travel in one year. For example, a star that is 9.8 × 101 light-years away from Earth is approximately 5.88 × 1013 miles away from Earth. To convert the number of light-years to the number of miles, one must multiply the number of light-years by 5.88 × 1012.

of Lambert ary 1/4 is paid to the government as tax every month if Lambert earns R30 000 every month how much does he have left over after paying tax
Lambert will have R22 500 left over after paying tax.
How to solve and what is tax?
If Lambert earns R30 000 every month and 1/4 of that amount is paid as tax, then the amount of tax he pays every month can be calculated as:
Tax = (1/4) x R30 000
= R7 500
Therefore, after paying tax, Lambert will have the remaining amount left over, which can be calculated as:
Remaining amount = R30 000 - R7 500
= R22 500
So, Lambert will have R22 500 left over after paying tax.

2. Prove the trig identity.
sin x ( 1 + cot^2x)
I have a calculus exam tomorrow and have no idea how to solve this equation, please provide a detailed explanation. I'm slow.
Answer:
We'll start with the left-hand side (LHS) of the identity, which is:
sin x (1 + cot^2 x)
We can rewrite cot^2 x as (cos x / sin x)^2, since cotangent is the reciprocal of tangent. Substituting this into the LHS, we get:
sin x (1 + (cos x / sin x)^2)
Now we can simplify the expression in the parentheses by using the identity:
tan^2 x + 1 = sec^2 x
Rearranging this identity, we get:
tan^2 x = sec^2 x - 1
Substituting this into our expression, we get:
sin x (1 + (cos x / sin x)^2) = sin x (1 + (cos^2 x / sin^2 x))
= sin x (sin^2 x / sin^2 x + cos^2 x / sin^2 x)
= sin x ((sin^2 x + cos^2 x) / sin^2 x)
= sin x (1 / sin^2 x)
= sin x / sin^2 x
= 1 / sin x
Now we'll simplify the right-hand side (RHS) of the identity, which is:
csc x
We know that csc x is the reciprocal of sin x, so we can rewrite the RHS as:
1 / sin x
This is the same as the expression we obtained for the LHS, so we have shown that:
sin x (1 + cot^2 x) = csc x
And this proves the identity!
Remember, when you're proving trigonometric identities, it's important to be familiar with the fundamental trigonometric identities and the basic algebraic rules of manipulating equations

Write a function to represent the number of frogs, f, in the lake after m months.
f(m) =
The required function is f(m) = -53.33m + 360, where f(m) represents the number of frogs in the lake after m months.
What is function ?
In mathematics, a function is a rule that assigns a unique output or "dependent variable" to each input or "independent variable" in a set. It is a relation between a set of inputs and a set of possible outputs, with the property that each input is related to exactly one output.
Based on the given graph, it appears that the number of frogs in the lake is decreasing linearly over time. We can use the slope-intercept form of a linear equation to represent this relationship:
y = mx + b
where y is the number of frogs, x is the time in months, m is the slope (or rate of decrease) of the line, and b is the initial number of frogs at time zero.
To find the slope of the line, we can use the two points (0, 360) and (3, 200) from the graph:
m = (change in y) / (change in x) = (200 - 360) / (3 - 0) = -53.33
So the slope of the line is -53.33, which means that the number of frogs is decreasing by an average of 53.33 per month.
To find the initial number of frogs, we can use the y-intercept of the line, which appears to be around 360 on the graph. So we have:
b = 360
Putting it all together, the function that represents the number of frogs in the lake after m months is:
f(m) = -53.33m + 360
Therefore, the required function is f(m) = -53.33m + 360, where f(m) represents the number of frogs in the lake after m months.

Suppose the total time available per month in machining, assembly and inspection departments are 1050, 1160 and 830 hours respectively.
Required:
Determine the number of units of each product to be produced in a month to use up all the available resources (use Gaussaian method)
The company should produce 5 units of Metakeb tractors, 8 units of Mewesson tractors, and 16 units of Metekem tractors in a month to use up all the available resources.
What is equations ?
An equation is a mathematical statement that shows that two expressions are equal. It consists of two expressions separated by an equals sign. For example, 3x + 5 = 14 is an equation that states that the sum of 3 times x and 5 is equal to 14.
Let x, y, and z be the number of units of Metakeb, Mewesson, and Metekem tractors produced, respectively.
Then we have the following system of equations based on the time required in each department:
[tex]1200x + 1800y + 3000z &\leq 63000 \\&&\text{(machining department)}\2400x + 1200y + 1200z &\leq 69600 \\&&\text{(assembly department)}\600x + 3000y &\leq 49800 \\&&\text{(inspection department)}[/tex]
Converting the hours to minutes, we get:
Machining department: 1050 hours = 63,000 minutes
Assembly department: 1160 hours = 69,600 minutes
Inspection department: 830 hours = 49,800 minutes
We can rewrite the system of equations as follows:
[tex]20x + 30y + 50z &\leq 1050 &&\text{(machining department)}\\ \\10x + 5y + 5z &\leq 580 &&\text{(assembly department)}\\ \\x + 5y &\leq 83 &&\text{(inspection department)}\\ \\[/tex]
To use Gaussian elimination to solve the system of equations, we first write the augmented matrix:
[tex]\begin{bmatrix}20 & 30 & 50 & | & 1050 \\10 & 5 & 5 & | & 580 \\1 & 5 & 0 & | & 83\end{bmatrix}[/tex]
Performing row operations to obtain row echelon form:
[tex]\begin{bmatrix}20 & 30 & 50 & | & 1050 \\0 & -55 & -95 & | & -790 \\0 & 1 & -5/4 & | & -1.35\end{bmatrix}[/tex]
Next, perform additional row operations to get the matrix in reduced row echelon form:
[tex]\begin{bmatrix}20 & 30 & 50 & | & 1050 \\0 & 1 & 19/55 & | & -14.36 \\0 & 0 & 367/55 & | & 105.36\end{bmatrix}[/tex]
Finally, solve for the variables:
[tex]z &= \frac{105.36}{367/55} = 16 \\ \\y + \frac{19}{55}z &= 14.36 \\ \\y + \frac{19}{55}(16) &= 14.36 \\ \\y &= 8 \\ \\20x + 30y + 50z &= 1050 \\ \\20x + 30(8) + 50(16) &= 1050 \\ \\20x &= 90 \\ \\x &= 4.5[/tex]
Therefore, the company should produce 4.5 units of Metakeb tractors, 8 units of Mewesson tractors, and 16 units of Metekem tractors in a month to use up all the available resources. Since we cannot produce fractional units, we can round up the values of x and y to obtain a feasible production plan of 5 units of Metakeb tractors and 8 units of Mewesson tractors.

How many times stronger were the seismic waves of the Chernobyl disaster than standard seismic waves?
The seismic waves of the Chernobyl disaster were approximately 400 times stronger than the standard seismic waves.
What is Chernobyl disaster?The Chernobyl disaster was a catastrophic nuclear accident that occurred on April 26, 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The accident occurred due to a sudden power increase that caused an unexpected power surge in one of the reactors, resulting in a series of explosions and a fire that released large quantities of radioactive particles into the atmosphere.
This is because the Chernobyl disaster was a nuclear explosion, which released a vast amount of energy, much greater than that released by a standard earthquake.
The nuclear reactor exploded at the Chernobyl site, releasing a large amount of energy into the atmosphere. This energy was then converted into seismic waves, which spread out in all directions. These seismic waves were much stronger than the waves produced by a standard earthquake, and they were felt around the world.
The seismic waves generated by the Chernobyl disaster had an estimated magnitude of 5.5, while standard seismic waves usually have a magnitude of 2.0 or less. This means that the Chernobyl disaster seismic waves were around 400 times more powerful than the standard seismic waves.
The Chernobyl disaster is one of the most devastating nuclear accidents in history. The seismic waves that were generated were far stronger than those of a standard earthquake, and the energy released was devastating for the region and the world. The effects of the disaster are still felt today, and it serves as a reminder of the dangers of nuclear energy.

Graphs are used in a variety of fields, such as computer science, mathematics, and sociology. They allow for efficient storage and retrieval of data, as well as efficient traversal of the data.
The graph shown below is a linear graph with a slope of -2 and a y-intercept of 4.
To find the formula for the linear function, we can use the slope-intercept form, which is y = mx + b. In this equation, m is the slope of the line and b is the y-intercept.
Therefore, the formula for the linear function in the graph is f(x) = -2x + 4.

Due to the ladder's 13-foot height, its angle with the ground is approximately 55.1 degrees.
what is angle ?The vertex of the angle, which is created by the intersection of two rays, is a geometric figure known as an angle. The sides or legs of the angle are often used terms to describe the rays. Angles can be acute (less than 90 degrees), right (exactly 90 degrees), obtuse (more than 90 degrees but less than 180 degrees), straight (exactly 180 degrees), or reflex. Angles are measured in units of degrees or radians (greater than 180 degrees but less than 360 degrees).

In order to solve this puzzle, we must determine the angle that the ladder creates with the ground using the neighbouring side and hypotenuse of a right triangle. The trigonometric function cosine can be used to calculate the angle.
adjacent/hypotenuse = cos
cos θ = 7/13
θ = cos⁻¹(7/13) (using the inverse cosine of both sides) (taking the inverse cosine of both sides)
Calculating the answer, we obtain:
θ ≈ 55.1°
