Answer:

  2. 26.2 m

  3. 117.2 cm

Step-by-step explanation:

You want the perimeters of two figures involving that are a composite of parts of circles and parts of rectangles.

The circumference of a circle is given by ...

  C = πd . . . . . where d is the diameter

The length of the semicircle of diameter 12.6 m will be ...

  1/2C = 1/2(π)(12.6 m) = 6.3π m ≈ 19.8 m

The two lighted sides of the rectangle have a total length of ...

  3.2 m + 3.2 m = 6.4 m

The length of the light string is the sum of these values:

  19.8 m + 6.4 m = 26.2 m

The length of the string of lights is about 26.2 meters.

The perimeter of the figure is the sum of four quarter-circles of radius 11.4 cm, and 4 straight edges of length 11.4 cm.

Four quarter-circles total one full circle in length, so we can use the formula for the circumference of a circle:

  C = 2πr

  C = 2π·(11.4 cm) = 22.8π cm ≈ 71.6 cm

The four straight sides total ...

  4 × 11.4 cm = 45.6 cm

The perimeter of the figure is the sum of the lengths of the curved sides and the straight sides:

  71.6 cm + 45.6 cm = 117.2 cm

The design has a perimeter of about 117.2 cm.

Additional comment

The bottom 12.6 m edge in the figure of problem 2 is part of the perimeter of the shape, but is not included in the length of the light string.

The value of the card was declining over the period  is from the month of January 2020 to July 2020.

To determine the period over which the value of the card was declining,

Identify the range of values for which the derivative of the function V(m) is negative.

Let's find the derivative of the function V(m),

V'(m)

= dV(m)/dm

= 500m - 3500

To determine when the value of the card is declining,  find when V'(m) is less than zero.

Setting V'(m) < 0,

⇒500m - 3500 < 0

Solving for m,

⇒500m < 3500

⇒m < 7

The value of the card is declining for values of m less than 7.

Since m represents the approximate number of months since the start of 2020,

The declining period can be determined as the time from the start of 2020 to the 7th month.

Hence, the period over which the value of the card was declining is from January 2020 to July 2020.

Answer:

so 3%5+=67K and 9+=-8 is -1

Step-by-step explanation:

The break-even quantities are:

x = 80 and x = 22.

To find the break-even quantities, we need to set the total costs (C(x)) equal to the total revenues (R(x)):
C(x) = R(x)
1760 + 8x + 0.6x^2 = 100x - 0.4x^2

Now, we will rearrange the equation to form a quadratic equation:
0.6x^2 + 0.4x^2 + 8x - 100x + 1760 = 0

Simplify the equation:
x^2 - 92x + 1760 = 0

Now, to find the break-even quantities (x values), we will solve the quadratic equation. You can use the quadratic formula or factoring. In this case, factoring works:
(x - 80)(x - 22) = 0

So, the break-even quantities are x = 80 and x = 22.

Answer:

63/100

Step-by-step explanation:

Im Pretty sure this the correct answer

(a) In the equilibrium bidding strategy, bidders bid below their cost. The difference between a contractor's quote and their cost represents their strategic behavior in the auction.

By bidding below their cost, contractors try to increase their chances of winning the auction and securing the project.

This strategy allows them to potentially earn a higher profit if they win the auction and their cost turns out to be lower than their bid.

(b) The probability of contractor A winning when she submits a quote equal to b and contractor B submits a quote according to the equilibrium bidding function β(⋅) can be calculated as follows:

P(A wins) = P(A's bid ≤ B's bid)

Since the contractors' costs are independently drawn from a Uniform [0,1] distribution, the probability can be expressed as:

P(A wins) = P(A's cost + A's bid ≤ B's cost + B's bid)

Given that A's bid is b and B's bid is β∗(B's cost), the probability becomes:

P(A wins) = P(A's cost + b ≤ B's cost + β∗(B's cost))

(c) Contractor A's expected payoff when she has a cost of completing the project equal to c and submits a quote equal to b, while her rival bids according to the equilibrium strategy βx(⋅), can be calculated as follows:

Payoff(A) = P(A wins) × (b - c)

Using the probability expression from part (b), the expected payoff can be written as:

Payoff(A) = P(A's cost + b ≤ B's cost + βx(B's cost) × (b - c)

(d) To show that the bidding strategy βx(c) = 2/(1+c) is a (symmetric) Bayesian Nash Equilibrium, we need to verify two conditions:

(i) the strategy is optimal for a contractor given the strategies of other bidders, and

(ii) no bidder has an incentive to deviate from the equilibrium strategy.

(i) Optimality: Given the bidding strategy βx(c) = 2/(1+c), a bidder's expected payoff is maximized when they follow this strategy. This can be shown by calculating the expected payoff for a bidder who anticipates a cost of completing the project as c and submits a quote equal to βx(c). The expected payoff is maximized when the bidder follows the equilibrium strategy.

(ii) No incentive to deviate: Suppose a bidder deviates from the equilibrium strategy and chooses a different bidding strategy. In this case, the bidder's expected payoff would be lower than or equal to the expected payoff obtained by following the equilibrium strategy. Therefore, no bidder has an incentive to deviate from the equilibrium strategy, indicating that βx(c) = 2/(1+c) is a Bayesian Nash Equilibrium.

They are used in navigation, astronomy, and surveying. Rays are also used in computer graphics, physics, and optics. In addition, rays are used in the study of optics to describe the behavior of light as it travels through different mediums.

According to the video above, the geometric object called a ray has the characteristics that it has one endpoint and extends in away from that endpoint without end.A ray is a line that starts at a single point and extends in one direction to infinity. Rays are commonly used in geometry to explain lines and line segments. A ray has one endpoint, called the endpoint of the ray, from which it starts. The other end of the ray continues in the direction in which it is pointed without any limit. A ray is named by using its endpoint and another point on the ray, with the endpoint first. For example, if ray A starts at point P and passes through point Q, we write the name of the ray as ray PAQ or ray QAP. Rays can be part of line segments and other geometric objects. They can also be used to explain angles and the direction of a light source. Rays are commonly used in mathematics, science, and engineering.

This problem is an example of the use of synthetic division. This can be used to divide polynomials when the divisor has the form (x-a), with a constant.

The steps in this algorithm are:

• 1. write the divisor as ,a,;

In this problem, a = -1.

• 2. write the dividend as the coefficients starting with the leading coefficient, in descending order of the terms' degrees;

In this problem, since the dividend is 3x³-2x²+3x-5, we should write:

3 -2 3 -5

• 3. bring down to the third row the leading coefficient;

In this problem, it's 3. So far, we obtained:

-1 | 3 -2 3 -5

3

• 4. multiply the leading coefficient by a and write the result in the second row;

In this problem, we have 3 * (-1) = -3. Thus, we obtain:

-1 | 3 -2 3 -5

-3

3

• 5. add the numbers on the second row:

-1 | 3 -2 3 -5

-3

3 -5

• 6. repeat steps 4 and 5 for the next coefficients:

-5 * (-1) = 5

3 + 5 = 8

8 * (-1) = -8

-5 - 8 = -13

-1 | 3 -2 3 -5

-3 5 -8

3 -5 8 -13

• 7. the obtained numbers on the third row are the coefficients of the quotient (with one degree less than the dividend), and the last number on the right is the remainder.

In this problem, we have:

Therefore, the statement is True.

The percentage of tires that will have a life of 45,000 to 55,000 miles is  68.27%. So the correct option is 68.27%.

To find the percentage of tires that will have a life of 45,000 to 55,000 miles, we can use the concept of the normal distribution.

First, we calculate the z-scores for both values using the formula:
z = (x - mean) / standard deviation

For 45,000 miles:
z1 = (45,000 - 50,000) / 5,000 = -1

For 55,000 miles:
z2 = (55,000 - 50,000) / 5,000 = 1

Next, we look up the corresponding values in the standard normal distribution table. The table will provide the proportion of data within a certain range of z-scores.

The percentage of tires with a life between 45,000 and 55,000 miles is the difference between the cumulative probabilities for z2 and z1.

Looking at the standard normal distribution table, the cumulative probability for z = -1 is 0.1587, and the cumulative probability for z = 1 is 0.8413.

Therefore, the percentage of tires that will have a life of 45,000 to 55,000 miles is:
0.8413 - 0.1587 = 0.6826

Converting this to a percentage, we get:
0.6826 * 100 = 68.26%

So the correct answer is 68.27%.

By using the arc length formula, we will see that the length of the curve is L = 1.48

Here we have the curve:

y = 2 - x^2   with 0 ≤ x ≤ 1

And we want to find the length of the curve.

The arc length formula for a curve y in the interval [x₁, x₂] is given by:

\(L =\int\limits^{x_2}_{x_1} {\sqrt{1 + \frac{dy}{dx}^2} } } \, dx\)

For our curve, we have:

dy/dx = -2x

And the interval is [0, 1]

Replacing that we get:

\(L =\int\limits^{1}_{0} {\sqrt{1 + (-2x)^2} } } \, dx\\\\L \int\limits^{1}_{0} {\sqrt{1 + 4x^2} } } \, dx\\\)

This integral is not trivial, using a table you can see that this is equal to:

\(L = (\frac{Arsinh(2x)}{4} + \frac{x*\sqrt{4x^2 + 1} }{2})\)

evaluated from x = 1 to x = 0, when we do that, we will get:

\(L = \frac{Arsinh(2) + 2*\sqrt{5} }{4} = 1.48\)

That is the length of the curve.
