The amount of total distance walked has walked by Eric in a man-made circular lake is 75.36 miles.

A circle's circumference is the length of its perimeter. The circumference of a circle can be calculated using length units such as centimeters, meters, or kilometers by opening a circle and measuring the boundary in the same way that we would measure a straight line.

Circumference = D* π

Total distance walked four times = 4.C

= 4 * D * π

= 4 * 6 * 3.14

= 75.36 miles

So, the total distance is 75.36 miles.

the rule for x terms is 1.5x - 1.5 and the rule for y terms is 4.5y - 4.5.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Given, the ordered pairs.(0,0) (1.5,4.5) (3,9) (4.5,13.5)

For x term:

The rule for x term that is 0, 1.5, 3, 4.5

The solution of the initial value problem is [tex]\frac{e^{-y}}{2} [siny - cosy] = -e^{-t} [t^2 + 2t + 3] + \frac{5}{2}[/tex].

Initial value issues are a specific kind of calculus issue. Calculus initial value issues include differential equations with a known beginning condition that identifies the function's value at a certain point. Finding the function that best describes the system is the goal of these puzzles, and this can be accomplished by integrating the differential equation.

There is always an unknown constant present when doing an integration with an indeterminate integral or without initial conditions. The constant of integration is what is commonly indicated by the letter C.

Given that the initial value problem is:

dy/dt= e^(y-t) sec(y)(1+t2)

This can be re written as follows:

dy/ dt = e^(y-t) (1 + t^2) / sec (y)

Separate the derivative in terms of y and t and take integration:

[tex]\int{e^{-y}cos(y)} \, dy = \int {e^{-t}(1 + t^2)} \, dt[/tex]

Integrate the following:

[tex]\frac{e^{-y}}{2} [siny - cosy] = -e^{-t} [t^2 + 2t + 3] + c\\[/tex]

The monthly Period interest rate is 1.67( nearest hundredth)

Annual percentage rate (APR) refers to the yearly interest rate you'll pay if you carry a balance on your credit card. Some credit cards have variable APRs, meaning your rate can go up or down over time.

To convert annual rate to monthly rate, when using APR, simply divide the annual percent rate by 12.

The APR of the card holder is 19.99%

The expanded logarithmic expression is 7log y + log x + 3log z.

The use of a logarithm can be utilised to solve issues that cannot be resolved using the concept of exponents alone. A logarithm is simply another way to describe exponents. Log interpretation is not that tough. It suffices to know that an exponential equation can also be written as a logarithmic equation in order to comprehend logarithms.

Exponent and logarithm are inverses of one another. This is explained in the section below. John Napier, a mathematician, first developed logarithms as a technique to perform computations simply, and other scientists, engineers, etc. immediately embraced this idea.

The given logarithmic equation is:

log ([tex]y^{7}xz^{3}[/tex])

Now, we can use the properties of logarithms to expand this fully.

Therefore,

log ([tex]y^{7}xz^{3}[/tex]) = log ([tex]y^{7}[/tex]) + log (x) + log ([tex]z^{3}[/tex])

Therefore,

log (y⁷) = 7 log y

log (z³) = 3 log z

Therefore, the expanded logarithmic expression is 7log y + log x + 3log z.

Step-by-step explanation:

The ratio is already in lowest terms so we found an equivalent ratio by multiplying both terms by 2.

Answer:

5 to 18

Step-by-step explanation:

Yes, this is true. This phenomenon is known as the Central Limit Theorem and it states that, as the sample size increases, the distribution of the sample mean converges to a normal distribution.

Yes, this is true. According to the Central Limit Theorem, as the sample size increases, the distribution of the sample mean converges to a normal distribution. This means that, when the sample size is large enough, the histogram of sample means will appear to be close to a normal distribution. This is because the mean of a large enough sample size will be close to the population mean, regardless of the shape of the original population distribution.

The Central Limit Theorem also states that the larger the sample size, the more closely the sample distribution will resemble a normal distribution. This is why, when the sample size is large enough, a histogram of sample means will appear to be a normal distribution.

The cost of painting the wall is Rs.48.75 .

The square shape wall whose length is 10m has a door of length 2m and breadth 1m.   It also has a window of length 1m and breadth 0.5m.

Therefore, the cost of painting the wall can be calculated as follows:

cost of painting per meters = Rs0.5 per metre square

Therefore, the area of the wall to be painted will exclude the window and the door.

Hence,

area of wall of the wall to be painted = area of the wall - area of the window - area of the door

Therefore,

area of wall of the wall to be painted = 10² - (1 ×  0.5) - (2 × 1)

area of wall of the wall to be painted = 100 - 0.5 - 2

area of wall of the wall to be painted = 97.5 metres²

Therefore,

1 metres square = Rs0.5

The formula for a sequence represents a pattern in the terms of the sequence. By finding an explicit formula for a sequence, we can generate any term of the sequence without having to list out all of the terms.

In this case, the sequence -9, -27, -81, -243 follows a pattern where each term is obtained by multiplying the previous term by 3. This can be represented by the formula [tex]h(n) = -9 * 3^n[/tex], where n is the index of the term in the sequence and [tex]3^n[/tex] represents 3 raised to the power of n.

In contrast, Shira's formula  [tex]h(n) = -3 * 3^n[/tex]  results in a different sequence, -3, -9, -27, -81, which does not match the given sequence.

For the function P = 3x + y, there is no solution present to maximize it.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The given objective function -

P = 3x + y

Subjected to the constraints -

5x + 7y ≥ 35

3x + 4y ≤ 12

x ≥ 0, y ≤ 0

First consider the inequality 5x + 7y ≥ 35.

The equation of the above inequality is as follows -

5x + 7y = 35

Find two points that satisfies the above equation.

Take x = 0, then -

5(0) + 7y = 35

7y = 35

y = 5

The first point is (0,5).

Take y = 0, then -

5x + 7(0) = 35

5x = 35

x = 7

The second point is (7,0).

Substitute (x,y) = (0,0) and see the direction of the region for 5x + 7y ≥ 35.

5(0) + 7(0) ≥ 35

0 ≥ 35

This is not true.

Therefore, the region is non-origin side.

Now consider the inequality 3x + 4y ≤ 12.

The equation of the above inequality is as follows -

3x + 4y = 12

Find two points that satisfies the above equation.

Take x = 0, then -

3(0) + 4y = 12

4y = 12

y = 3

The first point is (0,3).

Take y = 0, then -

3x + 4(0) = 12

3x = 12

x = 4

The second point is (4,0).

Substitute (x,y) = (0,0) and see the direction of the region for 3x + 4y ≤ 12.

3(0) + 4(0) ≤ 12

0 ≥ 12

This is true.

Therefore, the region is origin side.
