Bend 4.4 m of the wire into a circle and bend 5.6 m of the wire into a square in order to minimize the total area.  

Let x = length of the portion that is bent into a circle

Then, 10-x = length bent into a square

Each side of the square has length (10-x)/4

So, area of square = (10-x)2/16

x = circumference of circle = 2πr   So, r = x/(2π)

Therefore, Area of circle = πr2 = x2/(4π)

T = total area = (10-x)2/16 + x2/(4π)

                    = [(10-x)2π + 4x2 ]/(16π)

                    = [(100-20x+x2)π + 4x2]/(16π)

                    = [(4+π)x2 -(20π)x+100π]/(16π)

                    = [(4+π)/(16π)]x2 - (5/4)x + (25/4)

The graph of T is a parabola opening upward.  The minimum of T occurs at the vertex of the parabola.  

The x coordinate of the parabola is (5/4)/[(4+π)/(8π)] = (10π)/(4+π) ≈ 4.4  

Thus, Bend 4.4 m of the wire into a circle and bend 5.6 m of the wire into a square in order to minimize the total area.

The hybrid factor is f(w) Equals 50w + 25 according to the preceding statement. The hybrid value is measured in units of f (flowers) and w (weeks), etc. 30 weeks of Part A's synthesis function equal 1525.

A task is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is just the input value, we would state that y is a mathematical function

Given that:

f(s) = 2s + 25

s(w) = 25w

The following combination function is used to determine how many flowers will blossom over the course of w weeks: f(w)

f(s) = 2s + 25

Replace s with s(w)

f(s(w)) = 2(s(w)) + 25

Substitute s(w) = 25w

f(s(w)) = 2(25w) + 25

f(s(w)) = 50w + 25

Hence,

f(w) = 50w + 25

Flowers are used as the units of measurement for f(w).

30 weeks of flowers translates to:

w = 30

So, we have:

f(30) = 50*30+25

f(30) = 1525

Thus, there will be 1525 blossoms throughout the course of 30 weeks.

Answer: 77m

Step-by-step explanation:

The equation for the perimeter of a rectangle is: p = 2(length) + 2(width). We are given both perimeter and the length, so we can plug in these values to solve for what is missing.

332m = 2(89) + 2(width)

332m = 178 + 2(width)

154 = 2(width)

width = 77

Just combine like terms and get the variable (width) by itself on one side of the equation to solve. Hope this helps!

Answer:

width = 77 m

Step-by-step explanation:

Perimeter = sum of all sides

As a rectangle has 2 lengths and 2 widths making a total of four sides;

P = 2 ( l + w)

332 = 2 ( 89 + w)

332/2 = 89 + w

166 = 89 + w

166 - 89 = w

77 = w

Therefore, the width of the pool is 77 m

Answer:

12 people

Step-by-step explanation:

Total people in the company = 120

No. of People who assemble yo- yo's = 120 × (60/100

                                                               = 72

Now, we need 70% of the total people to assemble yoyo = 120 × (70/100)

                                                                                                = 84

We already have 72 people assembling yoyo,

No. of more people needed =  84 - 72 = 12

Hence, if we have 12 more people from other departments, 70% of the total people would be assembling yo-yo's.

The equation is,

→ 5 + 12.5v ≥ 170

Then the value of v will be,

→ 5 + 12.5v ≥ 170

→ 12.5v ≥ 170 - 5

→ 12.5v ≥ 165

→ v ≥ 165 ÷ 12.5

The coordinate of the vertices (x,y) after a reflection over the x-axis is (x, -y). It is also known as a rule.

What are coordinates?

Coordinates are two numbers (Cartesian coordinates) or a letter and a number that point to a specific point on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: x (horizontal) and y (vertical).

A reflection of a point, line, or figure in the x-axis entailed mirroring the image over the x-axis. In this case, the x-axis is referred to as the axis of reflection.

The rule for reflecting over the x-axis is to negate the value of each point's y-coordinate while keeping the x-value constant.

For instance, when point P with coordinates (7,3) is reflected across the x-axis and mapped onto point P', P"s coordinates are (7,-3). The x-coordinate for both points remained unchanged, but the y-coordinate changed from 3 to -3.

The total cost of the meal was $16.189.

What is the sales tax?

A sales tax is a consumption tax that is added to the price of goods and services. It is usually a percentage of the purchase price, and the percentage varies depending on the location and type of product or service.

We are trying to find the total cost of the meal including the sales tax. To do this, we need to calculate the amount of tax and add it to the cost of the meal.

The cost of the meal before tax is $15.20 and the sales tax rate is 6.5%. To find the amount of sales tax, we can multiply the cost of the meal by the sales tax rate as a decimal.

$15.20 x 0.065 = $0.989

The amount of sales tax is $0.989.

To find the total cost of the meal, we can add the amount of sales tax to the cost of the meal before tax.

$15.20 + $0.989 = $16.189

Hence, The total cost of the meal was $16.189.

The probability of each outcome is 1/12 or 0.083.

The probability of each outcome in the sample space can be calculated using the formula for permutations. The formula for permutations is nPk = n!/(n-k)!. In this case n is the number of gift cards (4) and k is the number of gift cards to be selected (2).  In this example, the sample space consists of 16 possible outcomes, and each outcome is equally likely. Thus, the probability of each outcome is 1/16. To calculate this, divide 1 by the total number of outcomes (16). This results in the probability of each outcome being 1/16.Therefore, nPk = 4P2 = 4!/2! = 12. Since each outcome is equally likely, the probability of each outcome is 1/12 or 0.083. This can be written as a fraction as 1/12 or as a decimal as 0.083.

The best description of the offspring of Protists is D. sometimes genetically different than both parents

Asexual reproduction in protists includes methods such as binary fission, budding and fragmentation, in these methods the offspring are always genetically identical to one parent.

Sexual reproduction in protists can be through conjugation, meiosis, or syngamy, in this case the offspring are not always genetically identical to one or both parents. It is possible for the offspring to be genetically different from both parents due to the genetic recombination that occurs during sexual reproduction.

So, the statement that best describes the offspring of protists is "sometimes genetically different than both parents" as it depends on the type of reproduction method used.

The second graph does not represent the y as a function of x.

What is the function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

The x value of a point where a vertical line intersects a function represents the input for that output y value.

If we can draw any horizontal line that intersects a graph more than once, then the graph does not represent a function because that y value has more than one input.

If we draw a line parallel to the y-axis it cuts the graph in more than one point.

So, that does not represent a function.

Answer:

We can use the formula A = P(1 + r/n)^(nt) to find out how long it takes for William's money to triple, where A is the final amount, P is the principal, r is the interest rate, t is the time in years and n is the number of times the interest is compounded per year.

A = P(1 + r/n)^(nt) = 550(1 + 0.02/12)^(12*t) = 3P

Solving for t we get

t = (ln(3)/ln(1+0.02/12))/12 = 49.41

For Violet's account, using the formula A=Pe^(rt) where A is the final amount, P is the principal, r is the interest rate, t is the time in years, we get:

t = ln(3) / (2 * e^-2) = 49.41

Therefore, it will take approximately 49.41 years for William's money to triple, and 49.41 years for Violet's money to triple.

So the difference in time is 0.
