The equation of the  circle , with diameter  DEis (x - 5)² + (y - 7)² = 80

An equation is an expression that appears as the relationship between two or more variables and numbers. since the  standard equation  for a circle  is (x - h)² + (y - k)² = r², where    (h, k)  is the center of the circle and r is the radius. It is given that the diameter of the circle is at D(-3, 3) and E(13, 11). So the coordinate of the center is:

h = (13 + (-3))/2 = 5

k = (3 + 11)/2 = 7

(h, k) = (5, 7) and the  Radius is diameter / 2 = 8√5 ÷ 2 = 4√5.

the equation will be : (x - 5)² + (y - 7)² = (4√5)² => (x - 5)² + (y - 7)² = 80

Step-by-step explanation:

The bird should fly to a point on the shoreline that is 4km from B to minimize total energy expenditure. A large W/L ratio means it's more efficient to fly over land, while a small ratio means it's more efficient to fly over water. The minimum ratio is 2.834. The W/L ratio should be 1 for the bird to fly directly to D, and 0 for the bird to fly to B and then along the shore to D. It takes a bird 1.4 times more energy to fly over water than land.

To minimize the total energy expended in returning to its nesting area, the bird should fly to the point on the shoreline that is 4 km from B. This can be found using the principle of least action, which states that the bird will choose the path that minimizes the integral of the energy expended along the path.

A large value of the ratio W/L would mean that it takes significantly more energy to fly over water than over land. A small value of the ratio would mean that there is not much difference in energy expenditure between flying over water and over land. The ratio W/L corresponding to the minimum expenditure of energy can be found using the same principle of least action as in part (a).

we are asked to determine the ratio W/L corresponding to the minimum expenditure of energy. Let x be the distance from B to C, and let y be the distance from C to D along the shoreline. Then the total energy expended in returning to its nesting area is given by

E(x, y) = L(13 - x - y) + W(√(25 - x²)) + W(√(y² + (13 - x)²))

To minimize E(x, y), we take partial derivatives with respect to x and y and set them equal to zero

dE/dx = L + Wx/√(25 - x²) - Wy/√(y² + (13 - x)²) = 0

dE/dy = L - Wy/√(y² + (13 - x)²) = 0

Solving for x and y, we get

x = 5√((W/L)/(1.4(W/L) - 1))

y = 13 - x - 5√((W/L)/(1.4(W/L) - 1))

The ratio W/L corresponding to the minimum expenditure of energy is obtained by substituting these values into the expression for E(x, y) and simplifying

W/L = 2.5(1.4 + √(1.96 + 4/25))/(4.9 - √(1.96 + 4/25))

W/L ≈ 2.834

Therefore, the ratio W/L corresponding to the minimum expenditure of energy is approximately 2.834.

To fly directly to its nesting area D, the value of W/L should be equal to 1. To fly to B and then along the shore to D, the value of W/L should be equal to 0.

If birds of a certain species reach the shore at a point 4 km from B, it takes 1.4 times more energy for the bird to fly over water than over land. This can be found by comparing the energy required to fly directly from the island to the point on the shoreline that is 4 km from B (which is entirely over water) to the energy required to fly along the shoreline from that point to D (which is entirely over land).

The optimal clutch size is 1.

a)The survivorship of an offspring, S, decreases with the clutch size, C.

Therefore, the formula is given as:

S = 0.5 - 0.1C

We need to find the optimal clutch size for this bird species.

We can do this by differentiating S with respect to C, and equating the result to zero.

That is:S = 0.5 - 0.1C => dS/dC = -0.1

Equating dS/dC to zero gives:-0.1 = 0 => C = 0

This implies that there is no optimal clutch size for this species.

However, since C represents clutch size, it must be a positive integer.

Therefore, we can choose a clutch size of 1, which will result in the highest survivorship of offspring. Hence, the optimal clutch size is

1.b)The optimal clutch size for a species with a survivorship-clutch size relationship of the form S = a - bC can be obtained by following the same procedure as above.

We can differentiate S with respect to C, and equate the result to zero.

That is:S = a - bC => dS/dC = -b

Equating dS/dC to zero gives:-b = 0 => C = 0

This implies that there is no optimal clutch size for this species. However, since C represents clutch size, it must be a positive integer. Therefore, we can choose a clutch size of 1, which will result in the highest survivorship of offspring. Hence, the optimal clutch size is 1.

The probability that the amount of time Gary takes to assist the next customer is:

To solve this problem, assume that the time it takes Gary to assist a customer follows an exponential distribution with a rate parameter λ = 1/3 customers per minute (since he assists three customers per hour on average).

a) To determine the probability that the time is between 6 and 12 minutes, calculate the cumulative distribution function (CDF) of the exponential distribution at t = 12 and subtract the CDF at t = 6.

P(6 < X < 12) = F(12) - F(6) = (1 - exp(-λ × 12)) - (1 - exp(-λ × 6))

Substituting λ = 1/3:

P(6 < X < 12) = (1 - exp(-(1/3) × 12)) - (1 - exp(-(1/3) × 6))

= 0.4168.

b) To determine the probability that the time is between 26 and 35 minutes, use the same approach:

P(26 < X < 35) = F(35) - F(26) = (1 - exp(-λ × 35)) - (1 - exp(-λ × 26))

Substituting λ = 1/3:

P(26 < X < 35) = (1 - exp(-(1/3) × 35)) - (1 - exp(-(1/3) × 26))

= 0.0404.

c) To determine the probability that the time is either less than 14 minutes or greater than 24 minutes, calculate the complementary probabilities:

P(X < 14) = 1 - exp(-λ × 14)

P(X > 24) = 1 - F(24) = 1 - (1 - exp(-λ × 24))

Substituting λ = 1/3:

P(X < 14) = 1 - exp(-(1/3) × 14)

P(X > 24) = 1 - (1 - exp(-(1/3) × 24))

Work done when a 100 lb rock is lifted to height of 3 ft is 9652.215 ft-lb.

What is meant by work done?

The work done on an object is equal to the force applied to it multiplied by the distance over which the force is applied. In this case, the force applied is the weight of the rock, which is equal to the force of gravity acting on it.

The weight of an object is given by the formula:

W = mg

Where m is the mass of the object (in this case, 100 lb) and g is the acceleration due to gravity (approximately 9.8 m/s^2 or 32.17405 ft/s^2).

So the weight of the rock is:

W = (100 lb)(32.17405 ft/s^2) = 3,217.405 ft-lb

The work done on the rock is equal to the force applied (its weight) multiplied by the distance it is lifted (3 ft), so the work done is:

Work = (3,217.405 ft-lb) x (3 ft) = 9652.215 ft-lb

Therefore, the work done when a 100 lb rock is lifted to a height of 3 ft is 9652.215 ft-lb.

When the graph is decreasing, the rectangles give an underestimate and when the graph is increasing, they give an overestimate. These trends are accentuated to a greater extent by areas of the graph that are steeper.

We only need to add up the areas of all the rectangles to determine the area beneath the graph of f. It is known as a Riemann sum. The area underneath the graph of f is only roughly represented by the Riemann sum. The subinterval width x=(ba)/n decreases as the number of subintervals n increases, improving the approximation. Increased sections result in an underestimation while decreasing sections result in an overestimation. We now arrive at the middle rule. The height of the rectangle is equal to the height of its right edges for a right Riemann sum and its left edges for a left Riemann sum. The rectangle height is the height of the top edge's midpoint according to the midpoint rule, a third form of the Riemann sum.

The solution to the equation is y = 17/9. So the option D is correct

The real power of equations is that they provide a very precise way to describe various features of the world. (That is why a solution to an equation can be useful, when one can be found. )

To solve for y in the equation 1/3 = 1/6 (y 1/9), we can follow these steps:

Simplify the right side of the equation by finding a common denominator for y 1/9:

1/3 = 1/6 (y + 1/9)

1/3 = (y/6)+(1/54)

To isolate the right-hand y term, subtract 1/54 from both sides of the equation:

1/3 - 1/54 = y/6

18/54 – 1/54 = y/6

17/54 = y/6

Solve for y by multiplying both sides of the equation by 6:

(17/54) * 6 = a

102/54 = a

Simplify by dividing both numerator and denominator by their greatest common factor, which is 6:

Increasing the absolute value of 'a' in a quadratic equation narrows the parabola and makes it steeper, while decreasing the absolute value of 'a' widens the parabola and makes it less steep

When the absolute value of the coefficient 'a' in a quadratic equation ax² + bx + c increases, it affects the shape and behavior of the quadratic function. Let's explore the impact of increasing and decreasing the absolute value of 'a' in a quadratic equation.

1. Increasing |a|:

When the absolute value of 'a' increases, the parabola becomes narrower or more elongated. If 'a' is positive, the parabola opens upward, and if 'a' is negative, the parabola opens downward. The vertex, which is the point where the parabola reaches its minimum or maximum, remains the same horizontally but moves upward or downward depending on the sign of 'a'. Increasing |a| makes the parabola steeper.

2. Decreasing |a|:

When the absolute value of 'a' decreases, the parabola becomes wider. If 'a' is positive, the parabola still opens upward, but it becomes less steep. If 'a' is negative, the parabola still opens downward, but it becomes less steep as well. The vertex remains the same horizontally, but it moves closer to the x-axis as |a| decreases.

In summary, increasing the absolute value of 'a' in a quadratic equation narrows the parabola and makes it steeper, while decreasing the absolute value of 'a' widens the parabola and makes it less steep. The vertex of the parabola remains the same horizontally but moves upward or downward depending on the sign of 'a'. The coefficient 'a' determines the overall shape and behavior of the quadratic function.

The matrix P that orthogonally diagonalizes matrix A is : P = [1 1;

To find the matrix P that orthogonally diagonalizes matrix A, we need to find its eigenvalues and eigenvectors.

Given matrix A:

A = [4 1; 1 4]

To find the eigenvalues, we solve the characteristic equation:

|A - λI| = 0

Where λ is the eigenvalue and I is the identity matrix.

Calculating the determinant:

|A - λI| = |4-λ 1| = (4-λ)(4-λ) - 1*1

|1 4-λ|

Expanding and simplifying:

(4-λ)(4-λ) - 1*1 = λ^2 - 8λ + 15 = 0

Factoring the quadratic equation:

(λ - 5)(λ - 3) = 0

So, the eigenvalues are λ1 = 5 and λ2 = 3.

To find the corresponding eigenvectors, we substitute each eigenvalue into the equation (A - λI) * X = 0, and solve for X.

For λ1 = 5:

(A - 5I) * X1 = 0

Substituting the values:

(4-5 1)(x1) = (0)

(1 4-5)(y1) = (0)

Simplifying:

-1x1 + y1 = 0

x1 - 1y1 = 0

This gives us x1 = y1. Let's choose x1 = 1, which leads to y1 = 1.

So, the eigenvector corresponding to λ1 = 5 is X1 = [1; 1].

Similarly, for λ2 = 3:

(A - 3I) * X2 = 0

Substituting the values:

(4-3 1)(x2) = (0)

(1 4-3)(y2) = (0)

Simplifying:

1x2 + y2 = 0

x2 + 1y2 = 0

This gives us x2 = -y2. Let's choose x2 = 1, which leads to y2 = -1.

So, the eigenvector corresponding to λ2 = 3 is X2 = [1; -1].

Now, we can construct the matrix P by using the eigenvectors as columns:

P = [X1 X2] = [1 1; 1 -1]

To find P^(-1), the inverse of P, we can use the formula for the inverse of a 2x2 matrix:

P^(-1) = (1 / (ad - bc)) * [d -b; -c a]

Substituting the values:

P^(-1) = (1 / (1*(-1) - 1*1)) * [-1 -1; -1 1]

= (1 / (-2)) * [-1 -1; -1 1]

= [1/2 1/2; 1/2 -1/2]

Finally, we can determine P^(-1)AP:

P^(-1)AP = [1/2 1/2; 1/2 -1/2] * [4 1; 1 4] * [1/2 1/2; 1/2 -1/2]

Performing the matrix multiplication:

P^(-1)AP = [5 0; 0 3]
