Answer: 465m squared

(But I think I did this wrong)

Step-by-step explanation:

First, find the area of the whole thing

So 23 x 23 = 529

Now the field: 16 x 16 = 64

Then, subtract both of the areas to find the area of the path:

529 - 64 = 465

The formula Area of sector =(θ/2) × r2 is used to calculate the area of a sector with a central angle expressed in radians, where r is the radius of the circle and is the angle subtended at the center expressed in radians.

The quantity of space included within the sector's perimeter is referred to as the sector's area in a circle. A sector always starts at the circle's center. The area of a circle encompassed between its two radii and the arc next to them is known as the sector of a circle.

A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends.

The 87% confidence interval for the size of the candles is (3.503 ounces, 3.937 ounces).

To calculate the 87% confidence interval, follow these steps:

1. Identify the sample size (n=15), sample mean (3.72 ounces), and standard deviation (0.963 ounces).

2. Determine the critical value (z) for an 87% confidence interval using a standard normal distribution table or calculator. For an 87% CI, the critical value is approximately 1.534.

3. Calculate the standard error (SE) using the formula SE = standard deviation / sqrt(n). In this case, SE = 0.963 / sqrt(15) ≈ 0.248.

4. Multiply the critical value (z) by the standard error (SE) to find the margin of error (MOE): MOE = 1.534 * 0.248 ≈ 0.380.

5. Find the lower limit of the confidence interval by subtracting the MOE from the sample mean: 3.72 - 0.380 = 3.503 ounces.

6. Find the upper limit of the confidence interval by adding the MOE to the sample mean: 3.72 + 0.380 = 3.937 ounces.

So, the 87% confidence interval for the size of the candles is (3.503 ounces, 3.937 ounces).

The total cost before the sales tax was 19.828 pounds.

For a party, Jordan purchased 3.8 pounds of turkey, 2.2 pounds of cheese, and 3.6 pounds of egg salad.

We have to determine the total cost before sales tax.

As per the question, we have prices as:

cost of turkey = 3.95 per pound

cost of egg cheese = 1.3 per pound

cost of egg salad = 0.89 per pound

The total cost of turkey = 3.8 × 3.95  = 15.01 pounds

The total cost of cheese = 2.2 × 1.3 = 2.86 pounds

The total cost of egg salad = 2.2 × 0.89 = 1.958 pounds

The total cost before sales tax = 15.01 + 1.958 +2.86

Apply the addition operation, and we get

The total cost before sales tax = 19.828 pounds

The dividing by 0.5 is not the same as dividing by 2 , because 0.5 and 2 are different numbers  .

Let us understand the Division with the help of example ;

let the number be 10 ;

first we divide the number 10 by 0.5 ;

this can be written mathematically as ⇒ \(\frac{10}{0.5}\)  ;

⇒ \(\frac{10}{\frac{1}{2} }\) = \(10\times2\) = 20 ;

So , on dividing 10 by 0.5 , we get the answer as 20 .

Second , the number 10 is divided by 2 ;

this can be written mathematically as ⇒ \(\frac{10}{2}\) ;

⇒ \(\frac{10}{2 }\)  = 5  ;

So , on dividing 10 by 2 , we get the answer as 5  .

To solve the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0, we can use algebraic methods and the unit circle to determine the values of x that satisfy the equation.

1. Start by rearranging the equation to a quadratic form: \(6sin^2(x)\) + 6sin(x) + 1 = 0.

2. Notice that the equation resembles a quadratic equation in terms of sin(x). Let's substitute sin(x) with a variable, such as u: \(6u^2\) + 6u + 1 = 0.

3. Solve this quadratic equation for u. You can use the quadratic formula or factorization methods to find the values of u. The solutions are u = (-3 ± √3) / 6.

4. Since sin(x) = u, substitute back the values of u into sin(x) to obtain the values for sin(x): sin(x) = (-3 ± √3) / 6.

5. To find the values of x, we can use the inverse sine function. Take the inverse sine of both sides: x = arcsin[(-3 ± √3) / 6].

6. The arcsin function has a range of [-π/2, π/2], so the values of x lie within that range. Use a calculator to find the approximate values of x based on the values obtained in step 5.

7. Plot the obtained x-values on the graph to show the solutions of the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0. The graph will illustrate the points where the curve intersects the x-axis.

If 2/3 of a mini pizza cost $2.40, then 1/3 of a mini pizza would cost half of that:

1/3 of a mini pizza = 1/2 * $2.40 = $1.20

To find the cost of 1/2 of a mini pizza, we can divide the cost of 1/3 of a mini pizza by 2:

Using trigonometric function the value of x is 51.3°.

What is trigonometric function?

The functions of an angle in a triangle are known as trigonometric functions, commonly referred to as circular functions. In other words, these trig functions provide the relationship between a triangle's angles and sides. There are five fundamental trigonometric functions: sine, cosine, tangent, cotangent, secant, and cosecant.

Here Let us take the given right triangle as ABC.

∠A = x , ∠B = 90° and AB = 25 , AC= 40

Now using Cosine ratio then

Cos  A = \(\frac{adjacent}{hypotenuse}\)

=> cos x = \(\frac{25}{40}\)

=> cos x = \(\frac{5}{8}\)

=> x = \(cos^{-1}\frac{5}{8}\)

=> x = 51.3°

Hence the value of x is 51.3°.

To find the inverse function of F(x) = 2x - 3, we replace F(x) with y, swap the positions of x and y, and solve for y. The inverse function is f⁻¹(x) = (x+3)/2.

To find the inverse function of F(x) = 2x - 3, follow these steps

Replace F(x) with y. The equation now becomes y = 2x - 3.

Switch the positions of x and y, so the equation becomes x = 2y - 3.

Solve for y in terms of x. Add 3 to both sides: x + 3 = 2y.

Divide both sides by 2 (x + 3)/2 = y.

Replace y with the notation for the inverse function, f⁻¹(x): f⁻¹(x) = (x + 3)/2.

So, the inverse function of F(x) = 2x - 3 is f⁻¹(x) = (x + 3)/2.

The integral of sec(y) dy from zero to one-sixth of pi is equal to the natural logarithm of the square root of 3 times 64 raised to a certain power.

To evaluate the integral ∫ sec(y) dy from zero to one-sixth of pi, we can use the trigonometric identity that the integral of sec(y) dy is equal to the natural logarithm of the absolute value of the secant of y plus the tangent of y.

Integrating sec(y) dy gives us ln|sec(y) + tan(y)|. Evaluating the integral from zero to one-sixth of pi, we substitute the upper and lower limits of integration into the expression and subtract the result at the lower limit from the result at the upper limit.

ln|sec(π/6) + tan(π/6)| - ln|sec(0) + tan(0)|

Simplifying this expression, we know that sec(π/6) = √3/2 and tan(π/6) = 1/√3. Additionally, sec(0) = 1 and tan(0) = 0.

ln|√3/2 + 1/√3| - ln|1 + 0|

ln|√3 + 1| - ln|1|

ln|√3 + 1|

Therefore, the integral ∫ sec(y) dy from zero to one-sixth of pi is equal to the natural logarithm of the square root of 3 plus 1, or ln(√3 + 1).

Because the absolute value equations behave differently in the different ranges.

For a given absolute value equation (or inequality)

We get two equations or inequalities:

x - a = b

x - a = - b

And this is why the solution leads to two equations, this originates in the fact that the parent absolute value function:

The statement to prove is that PQ is the shortest segment from point P to plane M when PQ is perpendicular to plane M.

To prove that PQ is the shortest segment from point P to plane M, we can use the concept of perpendicularity. When PQ is perpendicular to plane M, it forms a right angle with the plane.

In Euclidean geometry, it is known that the shortest distance between a point and a plane is along the line perpendicular to the plane passing through the point.

Therefore, since PQ is perpendicular to plane M, it follows that PQ is the shortest segment from point P to plane M. This can be mathematically proven using the principles of geometry and the definition of perpendicularity.
