The combined present worth of the costs associated with the proposed bridge design, including construction and annual operating costs, is $10,583,333.

To calculate the combined present worth of costs, we need to consider the construction cost and the annual operating cost over the infinite life of the bridge. We will use the concept of present worth, which is the equivalent value of future costs in today's dollars.

The present worth of the construction cost is simply the initial cost itself, which is $9,000,000. This cost is already in present value terms.

For the annual operating cost, we need to calculate the present worth of perpetuity. A perpetuity is a series of equal payments that continue indefinitely. In this case, the annual operating cost of $700,000 represents an equal payment.

To calculate the present worth of the perpetuity, we can use the formula PW = A / MARR,

where PW is the present worth, A is the annual payment, and MARR is the minimum attractive rate of return (also known as the discount rate). Here, the MARR is given as 12%.

Plugging in the values, we have PW = $700,000 / 0.12 = $5,833,333.

Adding the present worth of the construction cost and the present worth of the perpetuity, we get $9,000,000 + $5,833,333 = $14,833,333.

However, since we are looking for the combined present worth, we need to subtract the salvage value, which is zero in this case. Therefore, the combined present worth of the costs associated with the proposed bridge design is $14,833,333 - $4,250,000 = $10,583,333, rounded to the nearest dollar.

Step-by-step explanation:

Since there's a common denominator, we can simply substract the numerators. 4 - 10 = -6, and so the answer is -6/7.

Answer:

4.75 h

Step-by-step explanation:

(a) f(4) = -1, f(-6) = 1 and f(6) = 1

(b) x = 4 and -4, x = 0 and x = -7

(c) t = -8

(d) The set x = {-4, -3, -2, -1, 0, 1, 2, 3, 4}

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

(a) The values of f(x) for the given values of x can be found from the graph by looking at the y values corresponding to the given x values.

f(4) = -1

f(-6) = 1

f(6) = 1

(b) By looking to the y values as the given numbers, we can find corresponding x values.

f(x) = -1 ⇒ x = 4 and -4

f(x) = -5 ⇒ x = 0

f(x) = 2 ⇒ x = -7

(c) We have to calculate the point (t, 3) where the y value is 3.

f(x) = 3 when x = -8

So t = -8

(d) f(x) < 0 for the set of values of x {-4, -3, -2, -1, 0, 1, 2, 3, 4}

Hence using the diagram of the graph of a function, we can compute all the values.

Answer:

The tenth term is -14.

Step-by-step explanation:

To find the pattern and the tenth term, we need to first figure out the sequence to which these numbers belong. From the given numbers, it is not immediately clear what the sequence is, as they seem to be a random collection of integers and fractions.

One possible way to approach this problem is to look at the differences between consecutive terms in the sequence, as this can reveal a pattern.

Starting with the second term, we have:

-6 - (-2) = -4

-2 - 0 = -2

0 - 1 = -1

1 - 3/2 = -1/2

We notice that the differences are all negative, and they are all either -1 or -1/2. This suggests that the sequence is a decreasing arithmetic sequence, with a common difference of -1 or -1/2.

To confirm this, we can try to extend the sequence using the pattern we have found. Let x be the first term in the sequence, and let d be the common difference. Then the sequence can be written as:

x, x - d, x - 2d, x - 3d, ...

We know the values of the first four terms, so we can use them to solve for x and d:

x = -6 + d

x - d = -2

x - 2d = 0

x - 3d = 1

Subtracting the second equation from the first, we get:

2d = -4

So d = -2.

Substituting this value of d into the third equation, we get:

x - 2(-2) = 0

Solving for x, we get:

x = 4

So the sequence is:

4, 2, 0, -2, -4, -6, -8, -10, -12, -14, ...

The tenth term is -14.

To find the number of words memorized in the first 10 minutes, we need to integrate the given memory rate function, M'(t) = -0.009t + 0.41, over the time interval from 0 to 10. The number of words memorized in the first 10 minutes is approximately 4.055 words.

Integrating M'(t) with respect to t gives us the accumulated memory function, M(t), which represents the total number of words memorized up to a given time t. The integral of -0.009t with respect to t is (-0.009/2)t^2, and the integral of 0.41 with respect to t is 0.41t.

Applying the limits of integration from 0 to 10, we can evaluate the accumulated memory for the first 10 minutes:

∫[0 to 10] (-0.009t + 0.41) dt = [(-0.009/2)t^2 + 0.41t] [0 to 10]

= (-0.009/2)(10^2) + 0.41(10) - (-0.009/2)(0^2) + 0.41(0)

= (-0.009/2)(100) + 0.41(10)

= -0.045 + 4.1

= 4.055

Therefore, the number of words memorized in the first 10 minutes is approximately 4.055 words.

Answer:

Rational number . . . . . .

To ensure a zero cash flow in the portfolio, the writer needs to set up a portfolio that offsets the cash flow from selling the derivatives. The writer should have -3 underlying assets in the portfolio (meaning short sold assets)

The cash flow from selling 100 derivatives can be calculated as:

Cash Flow from selling derivatives = 100 * (Premium at time 0 - Expiry value)

Cash Flow from selling derivatives = 100 * (1.34 - 0.64) = 70

To offset this cash flow, the writer needs to include an equal and opposite cash flow from the underlying assets. Let's assume the writer buys ""x"" underlying assets.

Cash Flow from underlying assets = x * (Value at time 0 - Value at time 1)

Cash Flow from underlying assets = x * (36 - 57) = -21x

To make the cash flow from underlying assets equal to the cash flow from selling derivatives, we set up the equation:

-21x = 70

Solving this equation, we find:

x ≈ -3.33

Since the number of underlying assets must be an integer, we round -3.33 to the nearest integer, which is -3.

Therefore, the writer should have -3 underlying assets in the portfolio (meaning short sold assets).

It is possible to use a relational operator and math operators in the same expression.

In programming, you can use relational operators (e.g., <, >, ==, !=) and math operators (e.g., +, -, *, /) together in the same expression. This is often used in conditional statements or loops to compare calculated values.

For example, consider the following expression:

`if (2 * 3) > (4 + 1)`

In this expression, we have math operators (*) and (+) and a relational operator (>). The math operations are evaluated first, resulting in:

`if (6) > (5)`

Then, the relational operator (>) is evaluated, and the expression becomes:

`if True`

The expression is true because 6 is greater than 5.
