≤θ≤π/4, ≤r≤4The given region in polar coordinates is an area that is defined by the limits of θ and r as given above.

Here, θ is an angle made by the line segment with the positive x-axis and r is the distance of the point from the origin. In this case, the angle θ can be measured from the positive x-axis and r is the radius of the circle centered at the origin that bounds the region.

Therefore, the region is a sector of the circle of radius 4 centered at the origin which includes all points with angles between 0 and π/4 radians and with distances from the origin between 0 and 4.

The polar coordinates system is an alternative coordinate system that is used to describe points in a plane.

In this system, the position of a point is given by its distance from the origin and the angle it makes with a fixed line, usually the positive x-axis.

Answer: \(0.2\) or

Step-by-step explanation:

Try to avoid this mistake

At first, the water in the fruit was 25%, then it dropped to 20%. That means we just have to find the difference between 25% and 20%.

Subtract 20 from 25

\(20 - 25\\\\5\)

Therefore, we are left with 5%.

The mass of the fruit was 5% less. However, in some cases, it may be right, or wrong.

Here is the right solution

\(25\% - 20\%\)

Since percentages are over 100, it will be simple to solve

\(\frac{25}{100} -\frac{20}{100}\)

Simplify

\(\frac{25-20}{100}\\\\20-25=5\\\\\frac{5}{100}\\\\\frac{1}{20}\)

\(\frac{1}{20}=5\%\)

The mass of the fruit became 5 percent less.

Now

\(\\ \bull\tt\looparrowright \Delta \%=Initial\:percent-Final\:Percent\)

Answer:

The answer is below

Step-by-step explanation:

From the image attached, the coordinates of point A is at (2, -4).

Transformation is the movement of a point from its initial location to a new position. Types of transformation include dilation, reflection, translation and rotation.

If a point A(x, y) is reflected over the x axis, the new point is at  A'(x, -y)

If a point A(x, y) is translated a units right and b units down, the new location is at A'(x + a, y - b)

If a point A(x, y) is dilated by  factor of a, the new location is at A'(ax, ay)

If a point A(x, y) is  rotated 180° clockwise about the origin, the new location is at A'(-x, -y)

Hence:

For Quadrilateral ABCD is reflected over the x-axis, the coordinates of A' is at A'(2, 4)

For Quadrilateral ABCD is translated 2 units right and 1 unit down, the coordinates of A' is at A'(4, -5)

For Quadrilateral ABCD is dilated by a scale factor of 3, the coordinates of A' is at A'(6, -12)

For Quadrilateral ABCD is rotated 180° clockwise about the origin the coordinates of A' is at A'(-2, 4).

Step-by-step explanation:

The work done in stretching the spring from its natural length to 0.9 feet beyond its natural length is 3 foot-pounds.

This can be calculated using the equation W = F * d, where W is the work done, F is the force applied, and d is the distance the spring is stretched. In this case, F is 6 pounds and d is 0.5 feet (0.9 feet - 0.4 feet). Thus, W = 6 * 0.5 = 3 foot-pounds.

Force is a concept in physics that describes the influence that can change the motion of an object. Work done is the amount of energy transferred to or from an object when a force acts on it and causes it to move through a distance.

How much work (in foot-pounds) is done in stretching the spring from its natural length to 0.9 feet beyond its natural length?

The given question is related to the chi-square test, which is a statistical method used to test the relationship between two variables. The test measures how expected values compare to actual values to determine if they differ significantly. In this case, we need to determine the preferred tree type by nuthatches based on their proportion in the forest.

Hence, we can conclude that all three types of trees are equally preferred by the nuthatches.

To answer this question, we will use the chi-square test and calculate the expected counts and components of the chi-square statistic.The steps to solve the question are as follows:

Step 1: Determine the observed valuesLet's assume that there are three types of trees in the forest, A, B, and C, with proportion 0.4, 0.3, and 0.3, respectively. Let's further assume that a sample of 100 nuthatches was observed, and the number of nuthatches on each tree type is given as follows:Observed values:A: 40B: 30C: 30

Step 2: Calculate the expected valuesTo calculate the expected values, we need to multiply the proportion of each tree type by the total sample size. The expected values are given as follows:Expected values\(:A: 0.4 × 100 = 40B: 0.3 × 100 = 30C: 0.3 × 100 = 30\)

Step 3: Calculate the chi-square statistic The chi-square statistic can be calculated using the formula:χ2 = Σ (O - E)2/Ewhere O is the observed value, E is the expected value, and Σ is the sum of all values. The components of the chi-square statistic can be calculated as follows: Components of χ2:A: (40-40)2/40 = 0B: (30-30)2/30 = 0C: (30-30)2/30 = 0Total χ2 = 0

Step 4: InterpretationThe obtained value of χ2 is 0, which means that the observed and expected values are the same. It indicates that the nuthatches do not show a significant preference for any tree type in the forest.

Percent Error in estimate can be found using the formula:Percent error = `|((Estimated value - Actual value)/Actual value) × 100%|`Given that the amount of concrete needed is 2.52 cubic yards and the contractor estimates it as 3 cubic yards.To find the percent error, we need to calculate the actual amount of concrete needed, `A`.The volume of the concrete needed is 6ft x 17ft x 8inches or `1/2ft` (since 1ft = 12inches).

The volume can be calculated as:V = l × b × h`V = 6 × 17 × 1/2` `V = 51ft³`Since 1 yard is equivalent to 3 feet, 51 cubic feet is equal to `51/27 = 1.8889 yards³`.Therefore, the actual amount of concrete needed is approximately 1.89 cubic yards.Now we can find the percent error in the estimate using the formula:Percent error = `|((Estimated value - Actual value)/Actual value) × 100%|`= `|((3 - 1.89)/1.89) × 100%|`= `|0.582%|`.

Rounding to the nearest tenth of a percent, the percent error in the estimate compared to the actual amount of concrete needed is 0.6%.

Answer:

35 degrees.

Step-by-step explanation:

Since that the line that the exterior 100 degree angle is on is a straight line (which is 180 degrees) we can clearly see the supplementary angle is 180-100 which is 80. A triangle's interior angles add up to 180 degrees which means the missing angle is 180-80-6535 degrees.

Answer:

m angle FED is 35 degrees

Step-by-step explanation:

line DE is bisecting RF.

linear lines have a 180 degree angle.

you are given that m angle RDE is 100, meaning you can subtract 180-100 to find angle FDE.

angle FDE is 80 degrees.

in EVERY triangle, all of the angles always add up to 180 degrees. Knowing this, you can subtract 80 and 65 from 180 to find the missing angle.

180 - 80 - 65 = 35

m angle FED is 35 degrees

Step-by-step explanation:

The production cost of company 1 is higher than company 2, and when producing the same number of units, company 2 has a lower production cost than company 1. This indicates that when producing the same number of units, company 2 has a lower production cost than company 1.

The given function represents the production cost f(x), in dollars, for x number of units produced by company 1:f(x) = 0.25x² − 8x + 600

The following table represents the production cost g(x), in dollars, for x number of units produced by company 2:x     g(x)6     862.28     856.810   85512   856.814   862.2

To determine whether the production cost of company 1 is less than the production cost of company 2 when producing the same number of units, we must find the production cost of both companies for each given value of x and then compare them. Using the formula above, the production cost of company 1 for each given value of x is:

f(6) = 0.25(6)² − 8(6) + 600= 81 dollars

f(8) = 0.25(8)² − 8(8) + 600= 88 dollars

f(10) = 0.25(10)² − 8(10) + 600= 95 dollars

f(12) = 0.25(12)² − 8(12) + 600= 100 dollars

f(14) = 0.25(14)² − 8(14) + 600= 103 dollars

The production costs of company 2, which are given in the table, are:g(6) = 862.2 dollars

g(8) = 856.8 dollars

g(10) = 855 dollars

g(12) = 856.8 dollars

g(14) = 862.2 dollars

We can see that for each value of x, the production cost of company 1 is higher than the production cost of company 2. Therefore, when producing the same number of units, the production cost of company 2 is less than the production cost of company 1.

Answer:

The length is 225 yd, and the width is 175 yd.

Step-by-step explanation:

Let w = width.

Then the length = w + 50.

perimeter = 2(length + width)

800 = 2(w + 50 + w)

400 = 2w + 50

2w = 350

w = 175

w + 50 = 225

The length is 225 yd, and the width is 175 yd.

Answer:

225 * 175 yards,

Step-by-step explanation:

If the width is x then the length is x+50.

Perimeter = 2(width + length)

800 = 2( x + x + 50)

2x + 50 = 400

2x = 350

x = 175

So, the width is 175 yd and length is 225yd.

The value of the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is 0.653 or 65.3%.

The value of the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week can be calculated as follows:

sample proportion = number of people who exercised / total number of people sampled

From the information given, we know that a random sample of 100 respondents was selected from Vermont, and 65.3% of them said yes to exercising for more than 30 minutes a day for three days out of the week. Therefore:

number of people who exercised in Vermont = 65.3% of 100 = 0.653 x 100 = 65.3

So the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is:

sample proportion = 65.3 / 100 = 0.653

Therefore, the value of the sample proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is 0.653 or 65.3%.
