At the end of 18 years, there will be a total of $5,890.37 in the account.  

Compound interest is a powerful financial tool that can help you grow your money over time.

In the case of the $1,800 deposited into an account earning 6% interest compounded weekly, the total amount in the account at the end of 18 years can be calculated as follows:

Let P be the principal balance, r be the interest rate, n be the number of times the interest is compounded per year, and x be the number of years. Using the compound interest formula, we can calculate the amount in the account at the end of 18 years:

A = P(1 + (r/n))ⁿˣ

A = 1800 * (1 + (0.06/52))⁵²ˣ¹⁸

A = 5,890.37

70 degrees Fahrenheit is equal to approximately 21.1111 degrees Celsius (rounded to four decimal places).

The Celsius (symbol: °C) is an SI (International System of Units) derived unit of temperature.

The Fahrenheit (symbol: °F) is a unit of temperature that was widely used prior to metrication.

To convert a temperature from Fahrenheit (°F) to Celsius (°C),

We can use the following formula:

°C = (°F - 32) x 5/9

Where °C is the temperature in Celsius and °F is the temperature in Fahrenheit.

Substituting 70 for °F, we get:

°C = (70 - 32) x 5/9

Simplifying the expression:

°C = 38 x 5/9

°C = 21.1111111111

Therefore, 70 degrees Fahrenheit is equal to approximately 21.1111 degrees Celsius (rounded to four decimal places).

The integral of sec(x) is ln |sec(x) + tan(x)| + C.

The integral of sec(x) is:

∫sec(x) dx = ln |sec(x) + tan(x)| + C

where C is the constant of integration.

To solve this integral, you can use the method of substitution. Let u = sec(x) + tan(x). Then [tex]du/dx = sec(x)tan(x) + sec^2(x)[/tex], which can be simplified to du/dx = u tan(x). Rearranging, we get du/u = tan(x)dx.

Substituting these expressions into the integral, we have:

∫sec(x) dx = ∫(sec(x) + tan(x))/(sec(x) + tan(x)) dx = ∫(1/u) du

Integrating this expression gives:

∫(1/u) du = ln |u| + C = ln |sec(x) + tan(x)| + C

Therefore, the integral of sec(x) is ln |sec(x) + tan(x)| + C.

The answer is 84 pairs of pants.

Explanation:
According to the problem, she donated half of her pants to charity, which means she donated (1/2)x pairs of pants.

After donating half of her pants, she kept her 7 favorite pairs of pants. So, the number of pairs of pants she kept is 7.

The problem states that she was left with 35 pairs of pants after donating half of her pants and keeping her 7 favorite pairs. This means that the remaining number of pairs of pants is (x/2) - 7 = 35.

Solving for x, we get:

(x/2) - 7 = 35

x/2 = 42

x = 84

Therefore, Kim had 84 pairs of pants in the beginning.

The number of $56 dollar tickets to center section was 200 and the number of tickets costing $38 to the left and right sections were 200.

Let us consider the number of tickets to the center section be x and right and left sections be y.

Here the total number of tickets sold are 540.

So,  x+ y = 540  ---------> i

The cost of tickets cost $56 will be 56x

The cost of tickets cost $38 will be 38y.

The total cost was given as $24120

So, 56x+ 38y = 24120 -----------> ii

Multiplying equation i with 56,

56x + 56y = 30240  ------------> iii

Subtracting equation ii from equation iii

   56x+ 56y = 30240

-   56x + 38y = 24120

So 18y = 6120

      y = 6120/18 = 340

Since x+ y = 540

          x+ 340 = 540

          x = 540- 340 = 200

So the number of $56 ticket sold is 200 and the number of $38 ticket sold is 340.

What is the ratio?

A ratio is a relationship between two quantities, indicating how many times the first quantity contains the second. Ratios are often expressed as a fraction or in the form "a:b", where "a" and "b" are the two quantities being compared.

The given ratio of employees who play musical instruments to employees who play sports is 3:20. This means for every 3 employees who play musical instruments, there are 20 employees who play sports.

We are given that there are 40 employees who play sports. We can use this information to find the number of employees who play musical instruments as follows:

Let's start with the ratio of employees who play sports to employees who play music, which is 20:3. This means that for every 20 employees who play sports, there are 3 employees who play music.

We know that there are 40 employees who play sports, so we can set up a proportion to find the number of employees who play music:

20/3 = 40/x

where x is the number of employees who play music.

To solve for x, we can cross-multiply:

20x = 3 * 40

20x = 120

Then, we can solve for x by dividing both sides by 20:

x = 6

Probability is a way of evaluating how likely something is to happen. Several things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.  One is the probability of every event in a sample space.

Now in the given question ,

A probability density function (PDF) of a continuous random variable x is a function that describes the relative likelihood of x taking on different values in a continuous range. The PDF is defined such that the area under the curve between any two values a and b represents the probability of x being in that range, i.e., P(a ≤ x ≤ b).

Since probabilities are non-negative, the PDF of a continuous random variable must also be non-negative. That is, f(x) > 0 for all values of x. This condition ensures that the area under the curve is non-negative, which is necessary for it to represent a valid probability distribution.

In the given equation, the constant 6 represents the initial height of the football when it was thrown. This means that before the football was thrown, it was already at a height of 6 feet above the ground.

A mathematical equation proves the equality of two expressions by using symbols, numbers, and/or variables. Equations can be used to illustrate relationships between several numbers or to locate unknown values in order to solve problems.

An equation typically consists of two parts: the left-hand side (LHS) and the right-hand side (RHS), which are separated by an equal sign (=). The LHS and RHS can contain constants, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

a. The constant 6 in equation f(t) = 6 + 30t - 16t represents the initial height of the football when it was thrown.

b. The term 30t in the equation represents the vertical distance covered by the football per second due to its initial velocity. This term is calculated by multiplying the initial velocity of the football by the time t.

c. The squared term -16t^2 in the equation represents the effect of gravity on the height of the football. This term is calculated by multiplying half the acceleration due to gravity (-16 feet per second squared) with the square of time t.

Pania ate a quarter of the pizza, leaving 3/4 (since 1/4 + 3/4 = 1) for Pita and Paula.

Pita then ate one sixth of what remained, which is one sixth of 3/4 or 3/24, leaving 21/24 (or simplifying to 7/8) for Paula.

Paula then ate two fifths of what remained after Pita had eaten, which is two fifths of 7/8 or 14/40, leaving 26/40 (or simplifying to 13/20) for Penny.

The simplified answer is [tex]-16n^2 - 4n - 4.[/tex]

In mathematics, simplification refers to the process of simplifying an expression or equation without affecting its fundamental meaning or value. Using mathematical tools and rules to simplify an equation makes it simpler to manipulate or solve.

In algebra, simplification might take the form of factoring out common factors, grouping like concepts, or distributing multiplication across addition or subtraction. For instance, merging two like terms will simplify the formula 2x + 4x to 6x. The same strategy can be used to reduce the expression 3(x + 2) - 2(x - 1) to 3x + 4 by spreading out the multiplication and combining related terms.

Other types of mathematical simplification include determining the square root of a number, simplifying trigonometric functions, and reducing fractions to their simplest forms. In order to solve difficulties and comprehend mathematical concepts, simplification is a crucial step that removes superfluous complexity and facilitates understanding of the underlying structure of an equation or problem.
