Find the circumference of a circle with a diameter of 11 millimeters. use 13.4 for pi

In order to find the value of the expression, first let's calculate the operations inside the parenthesis:

Then, calculating the exponential expression and after that the product, we have:

So the final value is 112.

A boat decelerating at the rate of 8 meters per squared second will travel 1520 meters after 10 seconds.

The distance traveled by the boat after 10 seconds is the distance covered during the deceleration phase.

Since it is a constant acceleration, we can employ one of the equations of motion.

Recall that:

d = v₀t + 1/2 at²

where:

- d is the distance traveled

- v₀ is the initial velocity

- a is the deceleration rate

- t is the time

From the question,  we are given:

v₀ = 112 meters per second

a = 8 meters per square second

t = 10 seconds.

Plugging in these values into the formula:

d = (112 * 10) + (1/2 * 8 * 10²)

 = 1120 + (0.5 * 8 * 100)

 = 1120 + (0.5 * 800)

 = 1120 + 400

 = 1520

Therefore, the boat will travel 1520 meters after 10 seconds.

To simplify the equation we will multiply 7 on both the sides.

Then we will get the result as 7x > 98

Thus, we can say that the new inequality will be x > 14 ,

Hence , the mistake made by the student was that he didn't divided both the sides by 7 but only one side.

The correct answer is The standard deviation for Portfolio P is less than 25

This response is accurate because a portfolio made up of two stocks with a correlation of less than one will always have a standard deviation that is lower than the standard deviation of the stocks added in accordance with their weight in the portfolio. For example, in this scenario, both stocks have a weight of 50% and a standard deviation of 25%, so their sum will be.

The portfolio standard deviation will be smaller than 25% since (0.5*25%) + (0.5*25%) = 25%.

Therefore, the standard deviation for Portfolio P is less than 25

This example does not qualify as a binomial experiment because the conditions of a binomial experiment are not all met.

While there are only two possible outcomes (drawing a diamond or not), the other conditions are not satisfied. Specifically, the outcome of each trial is not independent of those of other trials because cards are drawn without replacement, and there is not a fixed number of n trials as the number of trials depends on how many cards are drawn until seven diamonds are obtained. Additionally, the probability of each possible outcome in any trial is not the same from trial to trial because the number of cards in the deck changes as cards are drawn.

The sum of 18.420 and 28.49, rounded to the correct number of significant figures, is 46.91.

To add the numbers 18.420 and 28.49, we align the decimal points and perform the addition. After adding the numbers, we obtain a sum of 46.910. However, we need to round the answer to the correct number of significant figures.

The rule for determining the number of significant figures in addition is to retain the same number of decimal places as the number with the fewest decimal places being added. In this case, 18.420 has three decimal places, while 28.49 has two decimal places. Therefore, we round the sum to two decimal places: 46.910 rounded to two decimal places is 46.91.

Thus, the sum of 18.420 and 28.49, rounded to the correct number of significant figures, is 46.91.

9b). The measure of <EJF is 90° as the angle EJF is a right angle made at the intersection of the rhombus diagonals.

The all out cost capability is C(x) = 2x + 110. The dollar amounts for the cost, revenue, and profit, as well as the number of units, are x.

The given minor expense (MC) for an item is MC = 2x + 5. Let's locate the function of total costs. Cost (C) = Total Cost (TC) / Number of Units (x)The total cost of 10 units is estimated to be $540, as we know from previous experience. We should substitute this worth in the above equation. C(10) = 540/10C(10) = 54Now, we should see as the proper expense. When there are no units produced, the fixed cost is presented as the cost.

That is when x = 0. Let's seek it out. When x is zero, C(x) equals Fixed Cost. From the given equation, MC equals 2x + 5, and when x is zero, MC equals 2(0) + 5 = 5. Let the fixed cost be a. Then,C(x) = 2x + 5aThe complete expense capability is given by C(x) = 2x + 5a. We really want to track down a with the end goal that when x = 10, the all out cost capability is 540.C(10) = 2(10) + 5a = 54On tackling, we get,a = 22The complete expense capability is given by,C(x) = 2x + 5a = 2x + 5(22) = 2x + 110Therefore, the all out cost capability is C(x) = 2x + 110.

Explanation:

The solution to the given initial value problem, obtained using Laplace transforms, is y(x) = 0. This means that the function y(x) is identically zero for all values of x.

To find the solution of the initial value problem using Laplace transforms for the equation d²y/dx² + 9y = 9sin(t)u(t - 3), where y(0) = y'(0) = 0, we can follow these steps:

Take the Laplace transform of the given differential equation.

Applying the Laplace transform to the equation d²y/dx² + 9y = 9sin(t)u(t - 3), we get:

s²Y(s) - sy(0) - y'(0) + 9Y(s) = 9 * (1/s² + 1/(s² + 1))

Since y(0) = 0 and y'(0) = 0, the Laplace transform simplifies to:

s²Y(s) + 9Y(s) = 9 * (1/s² + 1/(s² + 1))

Solve for Y(s).

Combining like terms, we have:

Y(s) * (s² + 9) = 9 * (1/s² + 1/(s² + 1))

Multiply through by (s² + 1)(s² + 9) to get rid of the denominators:

Y(s) * (s⁴ + 10s² + 9) = 9 * (s² + 1)

Simplifying further, we have:

Y(s) * (s⁴ + 10s² + 9) = 9s² + 9

Divide both sides by (s⁴ + 10s² + 9) to solve for Y(s):

Y(s) = (9s² + 9)/(s⁴ + 10s² + 9)

Partial fraction decomposition.

To proceed, we need to decompose the right side of the equation using partial fraction decomposition:

Y(s) = (9s² + 9)/(s⁴ + 10s² + 9) = A/(s² + 1) + B/(s² + 9)

Multiplying through by (s⁴ + 10s² + 9), we have:

9s² + 9 = A(s² + 9) + B(s² + 1)

Equating the coefficients of like powers of s, we get:

9 = 9A + B

0 = A + B

Solving these equations, we find:

A = 0

B = 0

Therefore, the decomposition becomes:

Y(s) = 0/(s² + 1) + 0/(s² + 9)

Inverse Laplace transform.

Taking the inverse Laplace transform of the decomposed terms, we find:

L^(-1){Y(s)} = L^(-1){0/(s² + 1)} + L^(-1){0/(s² + 9)}

The inverse Laplace transform of 0/(s² + 1) is 0.

The inverse Laplace transform of 0/(s² + 9) is 0.

Combining these terms, we have:

Y(x) = 0 + 0

Therefore, the solution to the initial value problem is:

y(x) = 0

1. We start by comparing the key (60) to the middle element of the list, which is 38. Since 60 is greater than 38, we know that the key must be in the second half of the list.
2. Next, we compare the key to the middle element of the second half of the list, which is 76. Since 60 is less than 76, we know that the key must be in the first half of the second half of the list.
3. We then compare the key to the middle element of the first half of the second half of the list, which is 50. Since 60 is greater than 50, we know that the key must be in the second half of the first half of the second half of the list.
4. Next, we compare the key to the middle element of the second half of the first half of the second half of the list, which is 72. Since 60 is less than 72, we know that the key must be in the first half of the second half of the first half of the second half of the list.
