Find the missing side length

Answer:

Step-by-step explanation:

We need to first find the perimeter of this oddly-shaped rink. We have a rectangle for which we are enclosing 3 of its sides, and the fourth "side" is a half-circle. Let's find the perimeter (or circumference) of the circle, divide it in half because we have half a circle, then add in the remaining 3 sides from the rectangle, shall we?

C = πd. The diameter of the circle is the same as the shorter length in the rectangle, 26. Therefore,

C = (3.14)(26) so

C = 81.64 m for a whole circle, and for half of that circle, the circumference is

C = 40.82 m

Now we can find the perimeter of the rink:

40.82 + 61 + 26 + 61 = p so

p = 188.82 m

If the fencing costs $6.20 per meter and we have 188.82 m, then the total cost is

\(cost=\frac{6.20dollars}{meter}*188.82meters\). The label "meter" cancels out, leaving us with

cost = $1170.82

Answer:

Area is 5 cm and perimeter is 12 cm

Step-by-step explanation:

Area: top left sqare:

1cm * 1cm = 1 cm

bottom rectangle:

1cm * 3 cm = 3 cm

top right square:

1cm * 1cm = 1 cm

Perimeter:

1 cm + 2 cm+ 3 cm+ 2 cm+ 1 cm + 1 cm + 1cm + 1cm  = 12 cm

The required points on difference between a stratified sample and a cluster sample are explained.

In a stratified sample the populace is partitioned into various portions and afterward we take irregular components from each section.

In a group test, the example is separated into sections (or bunches) and afterward the example is taken by choosing different clusters.

Consequently, in the group test we take ALL components from various bunches while in a separated example we take A few components from the various segments.

Answer:

To compare 2 2/3 to another mixed number, you need to convert both mixed numbers to improper fractions.

To convert 2 2/3 to an improper fraction, you need to multiply the whole number (2) by the denominator of the fraction (3), and then add the numerator (2). This gives you:

2 2/3 = (2 x 3) + 2/3 = 6 + 2/3 = 20/3

Now that you have the improper fraction for 2 2/3, you can compare it to the improper fraction of another mixed number.

For example, if you want to compare 2 2/3 to 4 1/2, you would convert 4 1/2 to an improper fraction:

4 1/2 = (4 x 2) + 1/2 = 8 + 1/2 = 17/2

Now that you have both mixed numbers as improper fractions, you can compare them by finding a common denominator and then comparing the numerators. In this case, the common denominator is 6, so you need to multiply 17/2 by 3/3 to get:

17/2 = (17 x 3)/(2 x 3) = 51/6

Now you can compare 20/3 and 51/6 by looking at their numerators:

20/3 = 6.666...

51/6 = 8.5

So 2 2/3 is less than 4 1/2.

Oven hours are a binding constraint because Tori needs 0.04 x 200, or 8 hours, to manufacture 200 chocolate chips, and the same is true for the upper-level restriction.

Binding restrictions are those whose removal would lead to the largest advances in entrepreneurship and growth. Some locations are unbound. The dual value measures how much the objective function's value rises for each additional unit of the variable's value. A constraint's dual value only deviates from zero when it equals its bound.

This is a binding constraint, and during optimization, its value was pushed as close as possible to the bound. If your answer matches the Right-Hand Side (RHS) of the inequality, the constraint is BINDING. If your response does not match the RHS of the inequality, the constraint is NON-BINDING.

When Partition(numbers, 5, 9) is called in Quicksort for the array (56,25,26,28,81,93,92,85,99,87), the pivot is 92. The low partition is (56,25,26,28,81,85,87).

When Partition(numbers, 5, 9) is called in Quicksort with the array numbers = (56, 25, 26, 28, 81, 93, 92, 85, 99, 87), the element at the midpoint between index 5 and index 9 is chosen as the pivot.  The midpoint index is (5 + 9) / 2 = 7, so the pivot is the element at index 7 in the array, which is 92.

After the partitioning step, all the elements less than the pivot are moved to the low partition, while all the elements greater than the pivot are moved to the high partition. The low partition starts at the left end of the array and goes up to the element just before the first element greater than the pivot.

In this case, the low partition after the partitioning step would be (56, 25, 26, 28, 81, 85, 87), which are all the elements less than the pivot 92. Note that these elements are not necessarily in sorted order yet, as Quicksort will recursively sort each partition of the array.

Profitability index is 1.387. Thus, the correct option is (c) 1.387.

The formula for calculating the profitability index is:

P.I = PV of Future Cash Flows / Initial Investment

Where,

P.I is the profitability index

PV is the present value of future cash flows

The initial investment in the project is $30 million. The cash flow at the end of the first year is $2.85 million.

The present value of cash flows can be calculated using the formula:

PV = CF / (1 + r)ⁿ

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

n is the number of periods

For the first-year cash flow, n = 1, CF = $2.85 million, and r = 11%.

Substituting the values, we get:

PV = 2.85 / (1 + 0.11)¹ = $2.56 million

To calculate the present value of all future cash flows, we can use the formula:

PV = CF / (r - g)

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

g is the constant growth rate

For the subsequent years, CF = $2.85 million, r = 11%, and g = 3.85%.

Substituting the values, we get:

PV = 2.85 / (0.11 - 0.0385) = $39.90 million

The total present value of cash flows is the sum of the present value of the first-year cash flow and the present value of all future cash flows.

PV of future cash flows = $39.90 million + $2.56 million = $42.46 million

Profitability index (P.I) = PV of future cash flows / Initial investment

= 42.46 / 30

= 1.387

Answer:

what is the question?

Answer to what?

Step-by-step explanation:

8.

the angle at a vertex (crossing point) outside of the circle (when both lines intersect with the circle arc, which is also the case for tangents) is half of the difference of both arc angles (the outer and the inner angles).

the outer angle is 250°. since the full circle is 360°, this makes the inner arc angle 360-250 = 110°.

the difference is 250-110 = 140.

and half of that difference is

140/2 = 70°.

so, x = 70°

9.

see 8.

the angle at the vertex outside the circle is half of the difference between outer and inner arc angle.

in fact, this is again about tangents (despite the picture), because the outer angle + the inner angle is again 360° (the full circle). this can only be, if the 2 lines are tangents splitting the outer and inner arc angles into 2 parts of 360° without remainder.

320 - 40 = 280

280/2 = 140

x = 140°

10.

see 8. and 9.

it is an extreme example, where the vertex of the 2 intersecting lines is exactly on the circle arc and the tangent point of the second line.

this makes the inner arc angle = 0°.

remember, the vertex angle (55°) is half of the difference of the outer (x) and inner (0°) arc angle.

55 = (x - 0)/2

110° = x

11.

remember the table question, where we found that the circle internal angle of 2 intersecting lines is half of the sum of both intersected arc angles ?

this is exactly this case again.

(120 + 50)/2 = 170/2 = 85°

x = 85°.

12.

first, like in 8. and 9., we determine the vertex angle. x is then the supplementary angle (together they have 180°) to this vertex angle, because the sum of all angles around one point on one side of a line is always 180°.

the vertex angle is

(125 - 15)/2 = 55°

x + 55 = 180

x = 125°.

13.

see 11.

the circle internal vertex angle is half of the sum of both circle arcs.

x = (70 + 30)/2 = 100/2 = 50°.

14.

again, an extreme case, where the vertex is on the circle arc. so, the second arc angle is 0°.

see also 12.

x is the supplementary angle of the vertex angle.

the vertex angle is

(80 + 0)/2 = 80/2 = 40°.

x + 40 = 180

x = 140°.

15.

it is difficult to read. I see the outer arc circle as 140°.

see 8., 9., 10.

the vertex angle x is

x = (140 - 70)/2 = 70/2 = 35°

do I sound like a broken record ? I at least feel that way. you should be able to apply the explanations from the previous questions to solve the new ones yourself.

Given:

Consider the given square is

\((2xy+5y)^2\)

To find:

The value of given square by using the identities.

Solution:

We know that,

\((a+b)^2=a^2+2ab+b^2\)            ...(i)

We have,

\((2xy+5y)^2\)

Using the identity (i), we get

\((2xy+5y)^2=(2xy)^2+2(2xy)(5y)+(5y)^2\)

\((2xy+5y)^2=4x^2y^2+20xy^2+25y^2\)

Therefore, the value of given square expression is \(4x^2y^2+20xy^2+25y^2\).

(i) The dual of the given LP problem can be found by following these steps:

1. For each constraint in the primal problem, create a dual variable. In this case, we have three constraints, so we'll have three dual variables: y1, y2, and y3.
2. The objective function of the dual problem will be the sum of the products of the primal variables and their corresponding dual variables. So, the dual objective function is:
  Maximize w = 3y1 + 2y2 + y3.
3. For each primal variable x, create a constraint in the dual problem with the coefficient of the corresponding dual variable equal to the coefficient of x in the primal objective function. So, the dual constraints are:
  y1 + 2y2 - y3 ≤ -2
  y1 + y2 + y3 ≤ -1
  y1, y2, y3 ≥ 0.

(ii) To find the optimal solution to the dual problem, we need to solve the optimal tableau of the dual problem. From the given information, we know that Row 0 of the optimal tableau is:
  w = 4x1 + e2 + (M-1)a2 + (M+2)a3 = 0.
 
  However, the given information does not provide any details about the values of x1, e2, a2, or a3. Therefore, without this information, we cannot determine the specific optimal solution to the dual problem.
