Answer:
Step-by-step explanation:a) To find the price of the car before VAT, we need to first calculate the percentage of VAT included in the price:
VAT% = (VAT / Total Price) x 100
where VAT% is the percentage of VAT, VAT is the value of VAT, and Total Price is the price of the car including VAT.
From the given information, we have:
Total Price = Birr 5,000,000
VAT% = 15% (assuming a VAT rate of 15% in Ethiopia)
Therefore, we can solve for the value of the car before VAT as follows:
Total Price = Car Price + VAT
Birr 5,000,000 = Car Price + 0.15Car Price
Birr 5,000,000 = 1.15Car Price
Car Price = Birr 4,347,826.09
So the price of the car before VAT is Birr 4,347,826.09.
b) To find the value of VAT, we can use the same formula as above and solve for VAT:
Total Price = Car Price + VAT
Birr 5,000,000 = Birr 4,347,826.09 + VAT
VAT = Birr 652,173.91
Therefore, the value of VAT is Birr 652,173.91.

Write the polynomial in standard form with roots of 1/4 and +5i
The polynomial with roots of 1/4 and +5i in standard form is:
f(x) = x² - (1/4)x² + 25x - (25/4)
To write the polynomial with roots of 1/4 and +5i in standard form, we need to use the fact that the roots of a polynomial are related to its factors. Specifically, if r is a root of a polynomial, then x - r is a factor of the polynomial.
Therefore, if the roots of our polynomial are 1/4 and +5i, then we know that the factors of the polynomial are:
(x - 1/4) and (x - 5i) and (x + 5i)
To get the polynomial in standard form, we need to multiply out these factors and simplify.
(x - 1/4) and (x - 5i) and (x + 5i) = (x - 1/4) and (x² - 25i²)
= (x - 1/4) and (x² + 25)
= x³ + 25x - (1/4)x² - (25/4)

Carl takes out a loan which accrues interest at a flat rate of 1.96% per quarter.
what is the equivalent yearly simple interest rate?
Carl will be charged 7.84% of the initial loan amount as interest.
When taking out a loan, it's important to understand the interest rate and how it will affect the total amount you will owe. In this case, Carl's loan accrues interest at a flat rate of 1.96% per quarter. This means that every quarter, Carl will be charged 1.96% of the initial loan amount as interest.
To determine the equivalent yearly simple interest rate, we use the formula: Yearly interest rate = Quarterly interest rate x 4. This formula works because there are four quarters in a year, so we can multiply the quarterly interest rate by four to get the annual interest rate.
In this case, the quarterly interest rate is 1.96%. Multiplying this by four, we get an annual interest rate of 7.84%. This means that over the course of a year, Carl will be charged 7.84% of the initial loan amount as interest.
Understanding the interest rate is important because it can significantly impact the total amount that you will owe on a loan. A higher interest rate means that you will pay more in interest over the life of the loan, which can make the loan more expensive overall.
By calculating the equivalent yearly simple interest rate, Carl can better understand how much he will owe in interest over the course of the loan and make an informed decision about whether or not to take out the loan.

The mass of the original sample was approximately 1592.5 grams.
A sample of an element with a half-life of 8 years has a mass of 10 grams after 100 years. What was the mass of the original sample?The half-life of an element is the time it takes for half of a given sample of that element to decay.
Let's assume that the original mass of the sample was x grams.
After the first half-life of 8 years, the mass of the sample would be x/2 grams.
After the second half-life (16 years total), the mass would be x/4 grams.
After the third half-life (24 years total), the mass would be x/8 grams.
We can continue this pattern until we get to 100 years (which is 12.5 half-lives):
Mass after 100 years = x/2^12.5
We also know from the problem that the mass after 100 years is 10 grams:
x/2^12.5 = 10
Solving for x:
x = 10 x 2^12.5
x ≈ 1592.5 grams

The mean number of days with 0. 01 inch or more precipitation per month for Lewiston, Idaho, is about 8. 7. Find the probability that in a given month
(a) There are exactly 9 days with 0. 01 inch or more precipitation.
(b) There are at most 9 days with 0. 01 inch or more of precipitation.
(c) There are more than 9 days with 0. 01 inch or more of precipitation
We will use the Poisson distribution, which is a probability distribution that models the number of events occurring in a fixed interval of time or space, given the average rate of occurrence and assuming that the events are independent and randomly distributed.
For this problem, we will assume that the number of days with 0.01 inch or more precipitation in Lewiston, Idaho, follows a Poisson distribution with parameter λ = 8.7.
(a) To find the probability that there are exactly 9 days with 0.01 inch or more precipitation, we can use the Poisson probability mass function:
P(X = k) = e^(-λ) * λ^k / k!
where X is the random variable representing the number of days with 0.01 inch or more precipitation, λ is the parameter of the Poisson distribution, and k is the number of events we are interested in.
Plugging in the values, we get:
P(X = 9) = e^(-8.7) * 8.7^9 / 9! ≈ 0.151
Therefore, the probability that there are exactly 9 days with 0.01 inch or more precipitation is approximately 0.151.
(b) To find the probability that there are at most 9 days with 0.01 inch or more precipitation, we can use the cumulative distribution function of the Poisson distribution:
P(X ≤ k) = ∑i=0^k e^(-λ) * λ^i / i!
Plugging in the values, we get:
P(X ≤ 9) = ∑i=0^9 e^(-8.7) * 8.7^i / i! ≈ 0.503
Therefore, the probability that there are at most 9 days with 0.01 inch or more precipitation is approximately 0.503.
(c) To find the probability that there are more than 9 days with 0.01 inch or more precipitation, we can subtract the probability of having 9 or fewer days from 1:
P(X > 9) = 1 - P(X ≤ 9) ≈ 0.497
Therefore, the probability that there are more than 9 days with 0.01 inch or more precipitation is approximately 0.497.

The area of the square is 16 square units.
The area of the rhombus is 24 square units.
Part 1: Using the distance formula, we can find the lengths of the diagonals:
Diagonal AC = √[tex][(7-1)^2 + (2-10)^2[/tex]] = √(36 + 64) = √100 = 10
Diagonal BD = √[[tex](12-(-4))^2 + (12-0)^2[/tex]] = √(256 + 144) = √400 = 20
Part 2: The area of a rhombus can be calculated using the formula: Area = (diagonal 1 x diagonal 2)/2.
So, for this rhombus, the area = (10 x 20)/2 = 100 square units.
Part 3: The area formulas for a square and rhombus are not interchangeable because they have different ways of computing their areas. A square has all four sides equal in length, while a rhombus has opposite sides equal in length. The diagonals of a square bisect each other at right angles, and each diagonal divides the square into two congruent triangles, so the area of a square is simply side length squared (Area =[tex]s^2[/tex]). However, the diagonals of a rhombus bisect each other at right angles, but they do not necessarily divide the rhombus into congruent triangles. Therefore, the area of a rhombus is calculated using the lengths of the diagonals (Area = (diagonal 1 x diagonal 2)/2).
For example, let's consider a square with side length 4 units and a rhombus with diagonals 6 units and 8 units.
The area of the square = [tex]4^2 = 16[/tex]square units.
The area of the rhombus = (6 x 8)/2 = 24 square units.

a. The two companies charge the same for 14 tons of sugar.
b. The cost when the two companies charge the same is $7953.50.
a. Let's represent the amount of sugar as x, and the total cost as C. Then we can set up the following equations for each company:
Company 1: C = 5143 + 200.75x
Company 2: C = 5500 + 175.25x
To find the amount of sugar for which the two companies charge the same, we can set the two equations equal to each other and solve for x:
5143 + 200.75x = 5500 + 175.25x
25.5x = 357
x = 14
So the two companies charge the same for 14 tons of sugar.
b. To find the cost when the two companies charge the same, we can plug in x = 14 into either equation. Let's use Company 1's equation:
C = 5143 + 200.75x

Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the antiderivative.)
g(v) = 5 cos (v) - 8/√(1-v^2)
g(v) = ____
The most general antiderivative of the function g(v) = 5 cos(v) - 8/√(1-v^2) is 5 sin(v) + 8 arcsin(v) + C, where C is the constant of the antiderivative.
To find the antiderivative of the given function g(v), we can use the basic antiderivative rules. The antiderivative of 5 cos(v) is 5 sin(v), as the derivative of sin(v) is cos(v) and we only need to reverse the process.
Similarly, the antiderivative of -8/√(1-v^2) can be found using the inverse trigonometric function arcsin(v), as its derivative is -1/√(1-v^2). However, we need to include a constant of integration, denoted by C, as the antiderivative is not unique.
So the most general antiderivative of g(v) is 5 sin(v) + 8 arcsin(v) + C, where C represents the constant of the antiderivative. To check the correctness of the answer, we can differentiate it and verify if it gives us the original function g(v) as the result.

Inayah claims that the pool is draining at a rate of 1. 36% per hour
The pool is draining at a rate of 1.36% per hour according to Inayah's claim.
What is the claimed rate at which the pool is draining?According to Inayah's claim, the pool is experiencing a draining at a rate of 1.36% per hour. This means that for every hour that passes, the pool's water level decreases by 1.36% of its total volume.
Understanding the rate at which a pool is draining is essential for monitoring and managing water levels. If the rate of drainage is accurate, it can help estimate how long it would take for the pool to reach a certain level or completely drain. Additionally, it aids in determining the necessary actions to maintain the pool's water balance and prevent potential issues such as overflow or inadequate water supply.
It is crucial to verify the accuracy of the claim by monitoring the pool's water level over a specific period. This can be done by measuring the change in water volume or using other reliable methods to ensure the drainage rate aligns with the claimed percentage.

Find the radius of the cylinder. Round to the nearest whole centimeter.
The cylinder has a height of 6 centimeters and a radius of r1. The volume of the cylinder is 302 cubic centimeters.
___ centimeters
Answer:
To find the radius of the cylinder, we can use the formula for the volume of a cylinder, which is pi*(r1^2)*h, where r1 is the radius and h is the height. Given that the cylinder has a height of 6 centimeters and a volume of 302 cubic centimeters, we can solve for r1 by dividing the volume by pi times the height, and then taking the square root of the result. After rounding to the nearest whole centimeter, the radius of the cylinder is approximately 5 centimeters.
