Areas of Circles are for \(490.873m^2\) radius 12.5m, \(706.858m^2\) for radius 15m, \(1256.637m^2\) for radius 20m.

The region encircled by a circle with radius r is known as πr² in geometry. Here, the Greek letter stands for the constant proportion of a circle's circumference to its diameter, which is roughly equivalent to 3.14159.

This formula, which was first discovered by Archimedes, can be derived by considering the circle as the boundary of a series of regular polygons. A regular polygon's area is equal to half its perimeter times the distance from its center to its sides. The equivalent formula,  \(A=\frac{1}{2} *2\pi r*r\) states that the area is equal to half the perimeter times the radius.

The limit for a circle is held by \(\pi r^{2}\).

Given;

1) r=12.5m

\(A=\pi r^2=\pi (12.5)^2=490.873m^2\)
2) r=15m;

\(A=\pi r^2=\pi (15)^2=706.858m^2\)

3) r=20m;

\(A=\pi r^2=\pi (20)^2=1256.637m^2\)

Areas of Circles are for \(490.873m^2\) radius 12.5m, \(706.858m^2\) for radius 15m, \(1256.637m^2\) for radius 20m.

The curve that describes the level curve of value c of the surface \(z=x^{2}/4 + y^{2}/25\)  where c < 0 is a hyperbola i.e., the correct option is B.

To find the level curve, we set the surface equation equal to the constant value c:
\(c = x^{2}/4 + y^{2}/25\)
Since c is negative, let's rearrange the equation to isolate the terms with x and y:
\(y^{2}/25 - x^{2}/4 = -c\)
Now, we can rewrite the equation in a more recognizable form by dividing both sides by -c:
\(y^{2}/(25 * -c) - x^{2}/(4 * -c) = 1\)
This equation represents a hyperbola, as it has the general form of the equation for a hyperbola centered at the origin:
\(x^{2}/a^{2} - y^{2}/b^{2} = 1\)
Therefore, the level curve is a hyperbola.

Answer:  x=12,-4

Step-by-step explanation:

The estimated resistance of a copper wire at a temperature of -26°C, assuming a Fahrenheit-Celsius conversion of F-22 = 0.0707C, is approximately 215.17.

To calculate the estimated resistance at -26°C, we can use the temperature coefficient of resistance for copper. The formula for estimating the resistance change with temperature is given by:

\(R2 = R1 * (1 + a * (T2 - T1))\)

Where R2 is the final resistance, R1 is the initial resistance (182), α is the temperature coefficient of resistance for copper, and T2 and T1 are the final and initial temperatures, respectively.

Given that the temperature difference is -26°C - 22°C = -48°C, and using the conversion F-22 = 0.0707C, we can calculate α as follows:

α = 0.0707 * (-48) = -3.3856

Substituting values into the formula, we have:

\(R2 = 182 * (1 + (-3.3856) * (-48 - 22)) \\ = 182 * (1 + (-3.3856) * (-70)) \\= 182 * (1 + 238.992) \\ = 182 * 239.992 \\ = 43678.864\)

Therefore, the estimated resistance of the copper wire at -26°C is approximately 215.17.

The magnitude of the angular velocity is 125.66 rad / s and the period is 0.05 seconds.

Step-by-step explanation:

The computation of the magnitude and the period is given below:

First we determine the angular velocity that transforming the revolutions per minute,  

So,

ω = (1200 rev / min) ×  (2π rad / rev) × (1 min / 60s)

ω = 125.66 rad / s

Now, the period is  

ω = 2π ÷ T

T = 2π ÷ (125.66 rad / s)

T = 0.05 s

Hence,  the angular velocity has a value of 125.66 rad / s and the period is 0.05 seconds.

An eating disorder characterized by bingeing and purging is called bulimia nervosa.

The minimum amount of body fat needed for good health is variable and can depend on factors such as age, gender, and individual circumstances. However, essential body fat is typically estimated to be around 3-5% for men and 8-12% for women.

The term used to describe a person who is very overfat is obese. Obesity refers to having excessive body fat, which can have negative effects on health.

People with anorexia nervosa, an eating disorder characterized by restrictive eating and an intense fear of gaining weight, often see themselves as too fat even when they are extremely thin. This distorted body image is a characteristic feature of anorexia nervosa.

A technique for assessing body fat levels that involves being weighed under water is called hydrostatic weighing or underwater weighing. It is considered one of the more accurate methods for determining body composition.

Step-by-step explanation:

The probability that the largest of n random samples is greater than the population median M is bounded above by\(1 - F(M)^(n-1) \times F(X(n))\).

Assumptions about the population and the sampling method.

Let's assume that the population has a continuous probability distribution with a well-defined median, and that we are taking independent random samples from this population.

Let \(X1, X2, ..., Xn\) be the random samples that we take from the population, where n is the sample size.

Let M be the population median.

The probability that the largest of these random samples, denoted by X(n), is greater than M.

Cumulative distribution function (CDF) of the population distribution to calculate this probability.

The CDF gives the probability that a random variable takes on a value less than or equal to a given number.

Let F(x) be the CDF of the population distribution.

Then, the probability that X(n) is greater than M is:

\(P(X(n) > M) = 1 - P(X(n) < = M)\)

Since we are assuming that the samples are independent, the joint probability of the samples is the product of their individual probabilities:

\(P(X1 < = x1, X2 < = x2, ..., Xn < = xn) = P(X1 < = x1) \times P(X2 < = x2) \times ... \times P(Xn < = xn)\)

For any x <= M, we have:

\(P(Xi < = x) < = P(Xi < = M) for i = 1, 2, ..., n\)

Therefore,

\(P(X1 < = x, X2 < = x, ..., Xn < = x) < = P(X1 < = M, X2 < = M, ..., Xn < = M) = F(M)^n\)

Using the complement rule and the fact that the samples are identically distributed, we get:

\(P(X(n) > M) = 1 - P(X(n) < = M)\)

= \(1 - P(X1 < = M, X2 < = M, ..., X(n) < = M)\)

=\(1 - [P(X1 < = M) \times P(X2 < = M) \times ... \times P(X(n-1) < = M) \times P(X(n) < = M)]\)

\(< = 1 - F(M)^(n-1) \times F(X(n))\)

Probability depends on the sample size n and the distribution of the population.

If the population is symmetric around its median, the probability is 0.5 for any sample size.

As the sample size increases, the probability generally increases, but the rate of increase depends on the population distribution.

The radical approximations of 7.07, 7.21, and 7.93 to the nearest whole number are:

2.65

2.68

2.82

Step-by-step explanation:

Sure, here's a step-by-step explanation of finding the approximate square root of 7.07, 7.21, and 7.93 to the nearest whole number:

Start by finding an approximate square root by making an educated guess or by using a calculator.

Use the initial guess to determine if the number is closer to the actual square root or to a smaller or larger value.

Refine the estimate by averaging the guess and the number divided by the guess.

Repeat the process of refining the estimate until a satisfactory level of accuracy is reached.

Here's an example for 7.07:

An educated guess for the square root of 7.07 could be 2.7

Dividing 7.07 by 2.7 gives an estimated value of 2.61, which is closer to the actual value.

To get a more accurate estimate, the average of 2.7 and 2.61 (2.655) is taken as the new estimate.

Repeat steps 2 and 3 until the desired level of accuracy is achieved.

After several iterations, the square root of 7.07 is approximately equal to 2.65.

Similarly, you can find the approximate square roots of 7.21 and 7.93.

This is the cosine function that has an amplitude of π/2 and a period of 3.

To write a cosine function with an amplitude of π/2 and a period of 3, we can start with the general form of a cosine function: y = a cos(bx).

The amplitude of a cosine function is the absolute value of a, so in this case, we have an amplitude of π/2, which means a = π/2.

The period of a cosine function is the distance between two consecutive maximum or minimum points. It can be found using the formula T = 2π / |b|. In this case, we have a period of 3, so we can solve the equation 3 = 2π / |b| to find the value of |b|.

First, let's find the value of b:
3 = 2π / |b|
Multiply both sides by |b|:
3|b| = 2π
Divide both sides by 3:
|b| = 2π/3

Since we assume that a > 0, we can take b = 2π/3 as the value of b.

Now we can write the cosine function using the values of a and b:
y = (π/2) cos((2π/3)x)

This is the cosine function that has an amplitude of π/2 and a period of 3.
