a piece of wire 10m long is cut into 2 pieces. one piece is bent into a square and the other into a circle. how much of the wire should be used for the square if you want to minimize the total enclosed area? please give an exact simplified answer.

Answers

Answer 1

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.

Using probability the value of p + q = -0.4

What is probability?

Probability is the likelihood of an event.

How to find the value of p + q?

Given the Venn diagram and that the probabilities are independent events.

The probability of A or B is given by

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Also, the probability of A and B is given by P(A ∩ B) = P(A)P(B)

So, we have that

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

P(A ∪ B) = P(A) + P(B) - P(A)P(B)

From the Venn diagram, we have that

P(A) = p + q

P(B) = q + 0.6

P(A ∩ B) = q

P(A ∪ B) = 0.2

So, substituting these into the equation, we have that

P(A ∪ B) = P(A) + P(B) - P(A)P(B)

0.2 = p + q + q + 0.6 -  q

0.2 = p + 2q - q + 0.6

0.2 - 0.6 = p + q

-0.4 = p + q

So, the value of p + q = -0.4

a ladder 26 feet long is leaning against the wall of a house (see the figure below). the base of the ladder is pulled away from the wall at a rate of 3 feet per second. how fast is the top of the ladder moving down the wall when its base is 10 feet from the wall?

Answers

The rate at which the top of the ladder is moving down the wall = 9 feet/second.

This is a problem of right triangle similarity.

We can use the Pythagorean theorem to find the height of the ladder, which is the hypotenuse of a right triangle.

We can use the relationship between similar triangles to find the rate at which the top of the ladder is moving down the wall.

Let x be the distance of the base of the ladder from the wall.

We know that the ladder is 26 feet long, so the height of the ladder is the square root of (26^2 - x^2).

We know that the base of the ladder is moving away from the wall at a rate of 3 feet per second.

So, the rate at which the top of the ladder is moving down the wall is (3 feet/second) * (height of ladder / x)

When x = 10 feet, the height of the ladder is the square root of (26^2 - 10^2) = the square root of (676) = 26 feet.

So, the rate at which the top of the ladder is moving down the wall is (3 feet/second) * (26 feet / 10 feet) = 9 feet/second.

EXPLANATION:

12 + 1 = 13

13/4

Answer: 5 4/7

Step-by-step explanation: First, we need to change both 1 5/7 and 3 1/4 into an improper fraction. So:

[tex]1 \frac{5}{7}[/tex] = [tex]\frac{12}{7}[/tex]

[tex]3\frac{1}{4}[/tex] = [tex]\frac{13}{4}[/tex]

So, now we need to cross-multiply 12/7 and 13/4.

That'd be 156/28

But wait. We analyze that 156 and 28 can be reduced by 4

So, 156 divided by 4 is 39, and 28 divided by 4 is 7. So now our improper fraction is 39/7. To make it an improper fraction, we divide 39 by 7, which would give us 5 4/7. I hope this helped!

A cell phone plan cost $27.70 per month for 500 minutes of talk time. It cost an additional $0.08 per minute for each minute over 500 minutes. To get email access, it cost 30% of the price for 500 minutes of talk time. Your bill, which includes email, is the same each month for 9 months. The total cost for all 9 months is $367.29. Write and solve an equation to find the number of minutes of talk time you use each month.

Answers

Answer:

567 minutes each month.

Step-by-step explanation:

Let x be the number of minutes of talk time used each month.

The cost for talk time beyond 500 minutes is $0.08 * (x - 500)

The cost for email is $27.70 * 0.3 = $8.31

The total monthly cost is $27.70 + $0.08 * (x - 500) + $8.31 = $35.99

The total cost for 9 months is $35.99 * 9 = $323.91

So we can set up the equation:

$27.70 + $0.08 * (x - 500) + $8.31 * 9 = $367.29

Solving for x, we get:

x = 567

So the number of minutes of talk time used each month is 567 minutes.

Answers

Yes, this results in a random sampling because every day the woodworker produces two chairs, and the company that buys the chairs randomly selects the days on which to check the chairs made that day.

This means that each item (each chair) has an equal chance of being selected, and each group of n items (in this case, two chairs) also has an equal chance of being selected. The probability of an item being selected can be calculated using the formula P(A) = n/N, where n is the number of items in the sample and N is the total number of items in the population. In this case, the probability of an item being selected is 2/2 = 1, and the probability of a group of two items being selected is 2/2 = 1. This shows that each item and each group of items has an equal chance of being selected, which means that this is a random sampling.

Answers

The length of the arc of the sector watered is 0.89π.

In the given question, a lawn sprinkler located at the corner of a yard rotates through 80 degrees and sprays water of 20 ft.

We have to find the length of the arc of the sector watered.

From the given question,

r = 20 ft, θ = 80 degree

A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends.

The formula for the length of the arc of the sector watered is

L = [tex]\frac{\theta}{360^{o}}\times 2\pi r[/tex]

Now putting the value

L = [tex]\frac{80^{o}}{360^{o}}\times 2\times\pi \times20[/tex]

Now simplifying the length

L = [tex]\frac{320^{o}}{360^{o}}\pi[/tex]

L = 0.89π

Converted (a) 2.2 kg = 77.6 oz, 4.83 lbm. (b) 12 lbf/in2 = 82.7 kPa, 620.6 mmHg. (c) 160 hp = 119,360 cal/s, 88,000 Btu/s. (d) 82 gallons = 328 quarts, 313,981.8 mL. (e) 34 in = 0.8636 m, 86.36 cm.

What is conversion factor ?

A conversion factor is a ratio of two equivalent measurements used to convert a quantity from one unit to another.

(a) To convert 2.2 kg to ounces, we can use the conversion factor 1 kg = 35.274 oz. So, 2.2 kg = 2.2 * 35.274 oz = 77.6 oz. To convert 2.2 kg to lbm, we can use the conversion factor 1 kg = 2.205 lbm. So, 2.2 kg = 2.2 * 2.205 lbm = 4.83 lbm.

(b) To convert 12 lbf/in2 to kPa, we can use the conversion factor 1 lbf/in2 = 6.894 kPa. So, 12 lbf/in2 = 12 * 6.894 kPa = 82.7 kPa. To convert 12 lbf/in2 to mmHg, we can use the conversion factor 1 lbf/in2 = 51.715 mmHg. So, 12 lbf/in2 = 12 * 51.715 mmHg = 620.6 mmHg.

(c) To convert 160 hp to cal/s, we can use the conversion factor 1 hp = 746 cal/s. So, 160 hp = 160 * 746 cal/s = 119,360 cal/s. To convert 160 hp to Btu/s, we can use the conversion factor 1 hp = 550 Btu/s. So, 160 hp = 160 * 550 Btu/s = 88,000 Btu/s.

(d) To convert 82 gallons to quarts, we can use the conversion factor 1 gallon = 4 quarts. So, 82 gallons = 82 * 4 quarts = 328 quarts. To convert 82 gallons to mL, we can use the conversion factor 1 gallon = 3785.4 mL. So, 82 gallons = 82 * 3785.4 mL = 313,981.8 mL

(e) To convert 34 in to m, we can use the conversion factor 1 in = 0.0254 m. So, 34 in = 34 * 0.0254 m = 0.8636 m. To convert 34 in to cm, we can use the conversion factor 1 in = 2.54 cm. So, 34 in = 34 * 2.54 cm = 86.36 cm.

Converted (a) 2.2 kg = 77.6 oz, 4.83 lbm. (b) 12 lbf/in2 = 82.7 kPa, 620.6 mmHg. (c) 160 hp = 119,360 cal/s, 88,000 Btu/s. (d) 82 gallons = 328 quarts, 313,981.8 mL. (e) 34 in = 0.8636 m, 86.36 cm.

P = €10,000r = 6% = 0.06

Substitute the given values into the compound interest formula to write an expression that describes the given scenario over t years:

[tex]\implies A=10000(1+0.06)^t[/tex]

[tex]\implies A=10000(1.06)^t[/tex]

Question 2

To calculate how much money will be in the fund after 10 years, substitute t = 10 into the equation from question 1:

[tex]\implies A=10000(1.06)^{10}[/tex]

[tex]\implies A=10000(1.79084769...)[/tex]

[tex]\implies A=17908.4769...[/tex]

Therefore, there will be €17,908.48 in the emergency fund after 10 years.

Question 3

If the annual rate is 6%, the monthly interest rate is the annual rate divided by 12 (since there are 12 months in a year):

[tex]\implies \dfrac{6\%}{12}=0.5\%[/tex]

Question 4

Given that are 10 years in the scenario, the exponent will be the number of months in 10 years:

[tex]\implies 10 \times 12 = 120[/tex]

Question 5

0.5% = 0.005

Therefore, the complete expression that describes the scenario, given an annual interest rate of 6% that compounds monthly over 10 years is:

[tex]\implies 10000(1 + 0.005)^{120}[/tex]

[tex]\implies 10000(1.005)^{120}[/tex]

Question 6

To calculate how much money will be in the emergency fund after 10 years if the interest compounds monthly, calculate the expression from question 5:

[tex]\implies 10000(1.005)^{120}[/tex]

[tex]\implies 10000(1.81939673...)[/tex]

[tex]\implies 18193.9673...[/tex]

Therefore, there will be €18,193.97 in the emergency fund after 10 years.

Question 7

Amount in fund when compounded annually = €17,908.48

Amount in fund when compounded monthly = €18,193.97

Therefore, there is more money in the emergency fund when it is compounded monthly as the compounding frequency is greater (interest is earned on both the principal and the interest, so the more frequent the compounding periods are, the more interest is earned).

The general rule about compounding in exponential functions is the higher the number of compounding periods, the greater the amount of compound interest.  

In terms of compounding interest in investment:

The annual interest rate should be divided by the compounding frequency, and the exponent should be multiplied by the compounding frequency.

two trains leave the station at the same time, one heading east and the other west. the eastbound train travels at miles per hour. the westbound train travels at miles per hour. how long will it take for the two trains to be miles apart? do not do any rounding.

Answers

It will take (miles / (mph eastbound + mph westbound)) hours for the two trains to be miles apart.

(miles / (mph eastbound + mph westbound)) * 60 minutes/hour = minutes

The time it takes for two trains to be a certain distance apart depends on the speed of each train and the distance between them. To calculate this, we can use the equation time = distance/speed. We can also use this equation to calculate the time for two trains traveling in opposite directions. To do this, we add the speed of the eastbound train (mph eastbound) and the speed of the westbound train (mph westbound) and divide the distance between the two trains (miles) by the total. This gives us the amount of time it will take for the two trains to be miles apart. After converting the answer to minutes, we get the amount of time it will take for the two trains to be miles apart.

in 6 years the age of my sister and her three children will be 90 years what will it in 4 years

Answers

The age of my sister and her three children in 4 years will be 70 years

How to find the age in 4 years

The age is added in 6 years to get 90 years> the addition is done as follows

Sister + 6 + Child1 + 6 + Child2 + 6 + Child3 + 6 + Child4 + 6 = 90 years

Sister + Child1 + Child2 + Child3 + Child4 + 6 + 6 + 6 + 6 + 6 = 90

Sister + Child1 + Child2 + Child3 + Child4 + 6 * 5 = 90

Sister + Child1 + Child2 + Child3 + Child4 = 90 - 30

Sister + Child1 + Child2 + Child3 + Child4 = 60

In 4 years the age will be

Sister + Child1 + Child2 + Child3 + Child4 + 4 * 5 = 90

Sister + Child1 + Child2 + Child3 + Child4 = 90 - 20

Sister + Child1 + Child2 + Child3 + Child4 = 70
