The product of (4 + √3)(4 - √3) is equal to 13.

To multiply the expression (4 + √3)(4 - √3), we can use the FOIL method, which stands for First, Outer, Inner, Last.

First, we multiply the first terms of each expression:

(4)(4) = 16

Next, we multiply the outer terms:

(4)(-√3) = -4√3

Then, we multiply the inner terms:

(√3)(4) = 4√3

Finally, we multiply the last terms:

(√3)(-√3) = -3

Combining all the terms together, we obtain:

(4 + √3)(4 - √3) = 16 - 4√3 + 4√3 - 3

Simplifying further, we have:

Anton saves £1200 each month.

To calculate this, we first need to find out how much Anton spends on rent. Since he spends half of his salary on rent, we can calculate it as £2000 / 2 = £1000.

Now, let's find out how much Anton has left for living expenses and savings. Since the ratio of living expenses to savings is 2:3, we can calculate the total ratio parts as 2 + 3 = 5.

To find out the ratio part for savings, we divide the total amount left by the total ratio parts: £2000 - £1000 = £1000.

Now, we can calculate the amount Anton saves each month by dividing the amount left for savings by the ratio part for savings: £1000 / 3 = £333.33 (rounded to £333).

Therefore, Anton saves approximately £333 each month.

In summary, Anton saves £1200 each month, which is half of his salary (£2000) minus the amount he spends on rent (£1000). This is based on a ratio of 2:3 for living expenses and savings, resulting in a monthly savings amount of approximately £333.

The conjecture is that as the number of sides of an inscribed regular polygon with a radius of 1 unit increases, the area of the polygon approaches π.

In this problem, you will investigate the areas of regular polygons inscribed in circles. The question asks to make a conjecture about the area of an inscribed regular polygon with a radius of 1 unit as the number of sides increases.

As the number of sides of a regular polygon inscribed in a circle increases, the polygon becomes more similar to a circle itself. Therefore, we can conjecture that the area of the inscribed regular polygon approaches the area of the circle with the same radius.

To calculate the area of a regular polygon, we can use the formula:

Area = (1/2) x apothem x perimeter

Since the radius of the circle is 1 unit, the apothem of the inscribed regular polygon is also 1 unit.

Now, let's consider the perimeter of the inscribed regular polygon. The perimeter is the distance around the polygon, and it will increase as the number of sides of the polygon increases.

As the number of sides increases, the inscribed regular polygon becomes more similar to a circle. In a circle, the perimeter is the circumference, given by the formula:

Circumference = 2πr

Since the radius is 1 unit, the circumference of the circle is 2π.

So, as the number of sides of the inscribed regular polygon increases, the perimeter approaches 2π.

Substituting the values into the formula for the area:

Area = (1/2) x 1 x 2π

Simplifying further:

Area = π

Therefore, the conjecture is that as the number of sides of an inscribed regular polygon with a radius of 1 unit increases, the area of the polygon approaches π.

The expected income from the sickness lottery is $5. The expected utility from the sickness lottery is approximately 2.23. The utility from the expected income from the sickness lottery is approximately 2.24. Based on these calculations, it can be inferred that the individual is risk-averse. The actuarially fair insurance premium for full coverage is $45. The certainty equivalent, which represents the guaranteed income level that the individual would accept instead of the uncertain outcome, is $5. As a risk-averse individual, the maximum amount the person would be willing to pay to eliminate the uncertainty is $0, as the certainty equivalent already matches the expected income.

The expected income from the sickness lottery can be calculated by considering the probabilities and possible outcomes. Since there is a 10% chance of falling sick and earning $0, and a 90% chance of working and earning $50, the expected income can be computed as follows:

Expected Income = (0.10 × $0) + (0.90 × $50) = $5

To calculate the expected utility from the sickness lottery, we need to assign utility values to different income levels. Let's assume the utility function is U = √(I), where I represents income. We can now calculate the expected utility:

Expected Utility = (0.10 × √($0)) + (0.90 × √($50)) ≈ 2.23

Next, we can calculate the utility from the expected income. Using the same utility function, the utility from the expected income of $5 can be determined:

Utility from Expected Income = √($5) ≈ 2.24

Based on the calculated expected utility and utility from expected income, we can infer that the individual is risk-averse. This is because the utility from the expected income ($5) is higher than the expected utility (2.23), indicating a preference for certainty.

The actuarially fair insurance premium for full coverage can be calculated by considering the probabilities and outcomes. In this case, since there is a 10% chance of having $0 income and a 90% chance of having $50 income, the premium should be set such that the expected value of the insurance payment equals the expected loss. The actuarially fair insurance premium can be calculated as follows:

Premium = (0.10 × $0) + (0.90 × $50) = $45

The certainty equivalent is the guaranteed income level that an individual would be willing to accept instead of the uncertain outcome. In this case, as a risk-averse individual, the certainty equivalent would be the income level that provides the same utility as the uncertain income. Using the utility function U = √(I), we can calculate the certainty equivalent:

Certainty Equivalent = (Utility from Expected Income)² = (2.24)² = $5

As a risk-averse individual, the maximum amount the individual would be willing to pay to eliminate the uncertainty is equal to the difference between the expected income and the certainty equivalent. In this case, the maximum amount would be:

Maximum Amount = Expected Income - Certainty Equivalent = $5 - $5 = $0

Therefore, the individual would not be willing to pay anything to eliminate the uncertainty, as the certainty equivalent already matches the expected income.

Based on the given table of values, the points (16, 16) and (100, 6.4) lie on the indifference curve through (16, 16). The points (49, 917) and (9, 21/3) lie on the indifference curve through (25, 25).

Moving on to the questions:

(a) What is the marginal rate of substitution at (25, 25)?

To calculate the marginal rate of substitution (MRS), we need to find the absolute value of the derivative dy/dx at (25, 25).

MRS = |dy/dx| = |-∂x^(3/2)/∂(5^(1/3))| = |∂(1/∂5)^(1/∂5)| = 1/5

(b) What is the marginal rate of substitution at (4, 32)?

To calculate the MRS, we'll substitute the values into the given equation: MRS = |-2x^(3/2)/∂6^(4)| = |-2(4)^(3/2)/∂(6^4)| = 8/∂(6^4) = 8/216 = 1/27

Given the information in Question 5, consider consumption bundles A=(20,14) and B=(18,16). To determine the preference between these bundles, we need to compare their positions relative to the indifference curves.

Bundle A: (20, 14)

Plugging these values into the second indifference curve equation: y = (20)^(64) ≈ 16,310

Bundle B: (18, 16)

Plugging these values into the second indifference curve equation: y = (18)^(64) ≈ 21

Since y(A) > y(B), we can conclude that bundle A is preferred to bundle B.

(a) The expression representing the number of feet is 3t. (b)  traveled since she started walking toward Chase is 4t. (c) the distance between Chase and Jamie is 200 - (3t + 4t). (d) Will reach after 25 seconds of walking.

(a) Chase travels at a constant speed of 3 feet per second, so to find the number of feet he has traveled, we multiply his speed by the number of seconds, which gives 3t.

(b) Similarly, Jamie travels at a constant speed of 4 feet per second, so the expression representing the number of feet she has traveled is 4t.

(c) The distance between Chase and Jamie can be calculated by subtracting the total distance traveled by Chase (3t) and Jamie (4t) from the initial distance of 200 feet. This gives the expression 200 - (3t + 4t).

(d) To find the time it takes for Chase and Jamie to reach each other, we need to solve the equation 200 - (3t + 4t) = 0, which simplifies to 200 - 7t = 0. Solving for t, we get t = 200/7 ≈ 28.57. Since t represents the number of seconds, we round down to the nearest whole number, so Chase and Jamie will reach each other after approximately 28 seconds of walking.

The solution of the system of equations is D (2, -1). This can be obtained by solving the equations simultaneously and finding the values of x and y that satisfy both equations.

To solve the system of equations, we can use the method of substitution or elimination. Let's use the elimination method:

Multiply the second equation by 2 to make the coefficients of x in both equations equal:

2(x + 3y) = 2(-1)

2x + 6y = -2

Now, subtract the first equation from this modified second equation:

(2x + 6y) - (3x - 2y) = -2 - 8

2x + 6y - 3x + 2y = -10

-x + 8y = -10

Simplify the equation:

x - 8y = 10

Now, we have a new system of equations:

x - 8y = 10

3x - 2y = 8

Solving this system of equations, we find that x = 2 and y = -1. Therefore, the solution is (2, -1), which corresponds to option D.

Since WY is equal to XY, which is 8, the length of WY is also 8

Since quadrilateral WXYZ is a rectangle, opposite sides are congruent. This means that WY is also equal to 8.

In a rectangle, the opposite sides are parallel and congruent, and the adjacent sides are perpendicular to each other.

Given:

XZ = 2c

ZY = 6

XY = 8

We can see that XY is the diagonal of the rectangle, and it forms a right triangle with sides XY, XZ, and ZY. Using the Pythagorean theorem, we can find the length of WY.

Using the Pythagorean theorem: XY² = XZ² + ZY²

Substituting the given values: 8² = (2c)² + 6²

64 = 4c² + 36

4c² = 64 - 36

4c² = 28

c² = 28/4

By combining like terms, the expression x + x²/2 + 2x² - x simplifies to (5/2)x², eliminating the other terms.

To simplify the expression x + x²/2 + 2x² - x by combining like terms, we can follow these steps:

1. Combine the terms with the same variable raised to the same power:
  x²/2 + 2x² = (1/2 + 2)x² = (5/2)x²

2. Combine the terms with the same variable (x):
  x - x = 0

3. Add up the remaining terms:
  (5/2)x² + 0 = (5/2)x²

Therefore, the simplified expression is (5/2)x².

Note: The term x and -x canceled each other out, leaving no contribution to the simplified expression.

(2+4i) + (4-i) = 6+3i. To add complex numbers, we add the real and imaginary terms separately. The real terms are 2 and 4, and the imaginary terms are 4 and -1. Adding the real terms gives us 6, and adding the imaginary terms gives us 3. Therefore, the simplified expression is 6+3i.

(2+4i) + (4-i) = (2+4) + (4-1)i = 6+3i

The first step is to add the real terms, which are 2 and 4. This gives us 6.

The second step is to add the imaginary terms, which are 4 and -1. This gives us 3.

Finally, we combine the real and imaginary terms to get the simplified expression, which is 6+3i.

The circumference of the circle field is given, to find the diameter the formula must be applied where the diameter of the circle is found by dividing the circumference with 3.14, the result is approximately 52.97

The diameter of the circle is the longest ray that is twice of radius. The circumference of the circle must be divided with the [tex]\pi[/tex] value to find the diameter of the circle. As it is known that the circumference of the circle is 2 times the value of [tex]\pi[/tex]and radius and the diameter is two time the radius hence the formula of finding the diameter when the circumference is given will be: d = C/[tex]\pi[/tex]

Here d stands for diameter, C stands for circumference

The value of [tex]\pi[/tex] is  3.14

Where C= 2[tex]\pi[/tex]r

and d= 2r

so the formula of diameter is

d= C/[tex]\pi[/tex]

d= 166.42/3.14

d= 52.97313

that can be approximately taken as 52.97

So when the circumference of the circular filed is 166.42 then the diameter of the field is 52.97. The diameter can also be said as the half of the radius and the relation between the circumference and the ratio between the value of pi and diameter.
