a) The perimeter of the shaded figure is P = 29.9 units

b) The area of the shaded figure is A = 27.14 units²

Given data ,

Let the circumference of the semicircle C = πr

On simplifying , we get

C = π ( 3 ) = 9.42 units

Now , the total number of straight lines is n = 6 with 2 units

So , perimeter of straight lines = 12 units

Each diagonal represents a hypotenuse of an equal-sided triangle with side = 3 units

So the length of each diagonal is 3√2 units

The perimeter of shaded figure P = 9.42 units + 12 units + 2 ( 3√2 units )

P = 29.9 units

b)

The area of the shaded figure is A

Now , the value of A is

A = area of semicircle + area of square + area of triangle

A = ( πr² )/2 + ( 2 )² + 2 ( 1/2 )bh

A = 14.14 + 4 + 9

A = 27.14 units²

Hence , the perimeter and area is solved

The As Fed weight of the bale is 733.33 lbs and in  1 ton (2000 lbs) of that hay there would be  1740 lbs of DM.

You have a bale of hay that is 87% DM, and there is 638 lbs of DM in that bale. To find the As Fed weight of the bale, you can use the following formula:

As Fed weight = (DM weight) / (% DM)

Step 1: Convert the percentage to a decimal:
87% DM = 0.87

Step 2: Plug the values into the formula:
As Fed weight = (638 lbs) / (0.87)

Step 3: Calculate the As Fed weight:
As Fed weight ≈ 733.33 lbs

So, the As Fed weight of the bale is approximately 733.33 lbs.

Now, to find how many pounds of DM would be in 1 ton (2000 lbs) of that hay, you can use the following formula:

DM in 1 ton = (2000 lbs) * (% DM)

Step 1: We already have the percentage as a decimal (0.87).

Step 2: Plug the values into the formula:
DM in 1 ton = (2000 lbs) * (0.87)

Step 3: Calculate the DM in 1 ton:
DM in 1 ton = 1740 lbs

Therefore, there would be 1740 lbs of DM in 1 ton (2000 lbs) of that hay.

If a given certificate C is a legitimate answer to the instance, we can check in polynomial time if it is (B, S1, S2, ..., Sm, K) of SETCOVER. Hence, the language SETCOVER is in NP.

To prove that the language SETCOVER is in NP, we need to show that given an instance (B, S1, S2, ..., Sm, K) of SETCOVER and a certificate C, we can verify in polynomial time whether C is a valid solution to the instance.

The certificate C in this case is a subset IC of {1, 2, ..., m} of size K, which represents the indices of the sets that form a cover for B. To verify whether C is a valid solution, we need to check two things:

Verify that IC has size K: We can simply count the number of elements in IC and check if it equals K. This can be done in O(m) time, which is polynomial in the size of the input.

Verify that the sets S_i for i in IC form a cover for B: We can iterate through the elements in B and check whether each element is present in at least one of the sets S_i, where i is in IC. Since B has at most |B| elements, and each set S_i has at most |B| elements, this can be done in O(K |B|) time, which is polynomial in the size of the input.

Therefore, If a given certificate C is a legitimate answer to the instance, we can check in polynomial time if it is (B, S1, S2, ..., Sm, K) of SETCOVER. Hence, the language SETCOVER is in NP.

The intercepts of the equation 5x - 3y = -30 include the following:

x-intercept = (-6, 0).

y-intercept = (0, 10).

In Mathematics and Geometry, the x-intercept is the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" or y-value is equal to zero (0).

When the y-value = 0, the x-intercept can be calculated as follows;

5x - 3y = -30

5x - 3(0) = -30

5x = -30

x = -30/5

x = -6.

When the x-value = 0, the y-intercept can be calculated as follows;

5x - 3y = -30

5(0) - 3y = -30

Account A has a principal of  $15,000

Account B has a principal of $6250

Hence, account A will earn the highest interest in the first month.

When we talk about the simple interest, we mean the kind of interest that is charged only on the principal sum and not on the interest of the former year. Given that 18 months is 1.5 years and 15 months is 1.4 years we can now have that;

The length of BD is 53 units.

We are given here that BD is (8x - 27) units and EC is (2x + 33) units. BD and EC are the diagonals of a trapezoid. As we know that diagonals of a trapezoid are equal. Therefore, we will equate the given diagonals of a trapezoid.

BD  =  EC

Substituting the given values of BD and EC

8x - 27  =  2x + 33

combining the like terms

8x - 2x  =  33 + 27

6x  =  60

x = 60/6

The series converges for all values of p < -1, and diverges for all values of p ≥ -1.

To apply the Integral Test, we need to verify that the terms of the series are positive and decreasing for all n greater than some fixed integer. For this series, note that the terms are positive since both the base and the natural logarithm are positive. To show that the terms are decreasing, we take the ratio of successive terms:

[tex]a(n+1)/a(n) = [(n+1)ln(n+1)]^p / [nln(n)]^p[/tex]

[tex]= [(n+1)/n]^p * [(1+1/n)ln(1+1/n)]^p[/tex]

Since (n+1)/n > 1 and ln(1+1/n) > 0 for all n, it follows that the ratio is greater than 1 and therefore the terms are decreasing.

To use the Integral Test, we need to find a function f(x) such that f(n) = a(n) for all n and f(x) is positive and decreasing for x ≥ 3. A natural choice is [tex]f(x) = x(ln(x))^p[/tex]. Note that f(n) = a(n) for all n and f(x) is positive and decreasing for x ≥ 3. Then we have:

integral from 3 to infinity of f(x) dx = integral from 3 to infinity of x(ln(x))^p dx

To evaluate this integral, we use integration by substitution with u = ln(x):

[tex]du/dx = 1/x, dx = x du[/tex]

So the integral becomes:

integral from ln(3) to infinity of [tex]u^p e^u du[/tex]

This integral converges for p < -1, by the Integral Test for Improper Integrals.

The original price of the ticket was $210 and the new price is $310.

To find the percentage increase, we can use the formula:

percentage increase = (new price - old price) / old price * 100%

So, the percentage increase in the ticket price is:

percentage increase = (310 - 210) / 210 * 100% = 47.62%

Therefore, the ticket price has increased by 47.62%.

If the airline charges an additional $50 baggage fee with the new ticket price of $310, then the new price will be $360.

To find the new percentage increase, we can use the same formula:

percentage increase = (new price - old price) / old price * 100%

So, the percentage increase in the ticket price with the additional $50 baggage fee is:

percentage increase = (360 - 210) / 210 * 100% = 71.43%

The cost of the wood for the walls of the playhouse is $1141.44.

To calculate the cost of the wood for the walls of the playhouse, we need to find the surface area of the walls and then multiply it by the cost per square foot.

The surface area of the walls of an octagonal pyramid can be calculated by finding the area of each trapezoidal face and adding them up. Since the side length of the pyramid is 3 feet and the slant height is 12 feet, we can use the Pythagorean theorem to find the height of each trapezoidal face:

h = √(12² - (3/2)²)

h = √(144 - 2.25)

h = √(141.75)

h ≈ 11.89 feet

The area of each trapezoidal face is:

A = 1/2 * (b1 + b2) * h

A = 1/2 * (3 + 3) * 11.89

A ≈ 35.67 square feet

There are 8 trapezoidal faces in the octagonal pyramid, so the total surface area of the walls is:

SA = 8 * A

SA ≈ 285.36 square feet

Finally, we can calculate the cost of the wood for the walls by multiplying the surface area by the cost per square foot:

Cost = SA * $4

Cost = 285.36 * $4

Cost = $1141.44

Therefore, the cost of the wood for the walls of the playhouse is $1141.44.
