consider a circle of radius 2 centered at the origin. find parameterizations of this curve under the following assumption. clearly state any restriction on the variable of parametrization

The number of arrivals who came in each day while this particular widget shop was open. Therefore, statement 2 is correct.

The process by which a sample of observations is selected from a population to assume the population is known as random sampling. This process ensures that the results we get from your sample should be close to what we would have gotten if we measured the complete population. So that all the units in the population have an equal chance of being chosen using the simplest random sample.

In the given scenario, the number of arrivals each day for the widget store should have equal chance. To be specific, we should only take into account the number of visitors on the days when the store is open.

The integral of k*f(x) equals the integral of f(x) multiplied by k because the total of k*f(x) equals the sum of f(x) multiplied by k.

K*F(x) Integral = K*Fintegral (x). This is inferred from the description of a definite integral as the upper limit of a term sum. The area under the curve can be divided into a number of rectangles and their areas added if we are taking the integral of a function from a to b. The integral then equals the maximum value of this total. The result is identical to the original sum increased by k if we multiply each term of the sum by a constant called k. as a result, the maximum allowed f(x) multiplied by k because the total of k*f(x) equals the sum of f(x) multiplied by k.

Answer:  To find the surface area of the figure, we need to add up the areas of all the individual faces. The triangular prism has three rectangular faces and three triangular faces, and the rectangular prism has six rectangular faces.

The triangular prism:

The area of one of the rectangular faces is (x * z)/2 = (5 * 8.75)/2 = 21.875 inches^2

The area of one of the triangular faces is (x * W)/2 = (5 * 6.2)/2 = 15.5 inches^2

The rectangular prism:

The area of one of the rectangular faces is x * y = 5 * 20 = 100 inches^2

So, the total surface area of the figure is

(3 * 21.875) + (3 * 15.5) + (6 * 100) = 65.625 + 46.5 + 600 = 712.125 inches^2

So the surface area of the figure is 712.125 inches^2

If an oil change at city auto is regularly $30 Mr. Allen has a coupon for 15% off. The  equation that can be used to find the sale price, S, of an oil change is: 3. s=0.85(30).

First step is to find the percentage left if he has a coupon for 15% off.

Percentage left = ( 1- 0.15)

Percentage left  = 0.85 or 85%

Now let find the sales price

Sales price = 0.85(30)

Sales price = $25.50

Given that ,

The right answer is that 90% of all random samples of 50 students from this high school would produce a 90% confidence interval that contains the actual mean amount of money students spend on lunch.

an appliance store manager noted that the sales of home appliances contributed

74 % of the store profits in the year 2010, and 82 % in the year 2011.

Thus, the profit in the year 2010 is 74 %.

The profit in the year 2011 is 82 %.

The increased profit from year 2010 to 2011 is ( 82-74 ) % = 8%

Answer:

6 divided by 2/3 = 9

Step-by-step explanation:

because it is mathematically correct (can check via calculator)

and the question includes the fact that S cut the rope into 9 sections from 6.

Answer:

No, these ratios are not equivalent.

Step-by-step explanation:

The dimension of the largest possible rectangular area that can be fenced for $4800 is 300 yard × 150 yard. The area, A of the rectangle as a function of its width, w is A = 300w - 1.5w².

Let the width of the rectangular area be "w" and its length be "l".

The cost of the east-west direction fencing is

2w * 12 = 24w

and the cost of the north-south direction fencing is

2l * 8 = 16l

Since the rancher wants to spend exactly $4800 on fencing, we can write an equation to represent the cost:

24w + 16l = 4800

Divide by 8

3w + 2l = 600

Therefore, l = 300 - 1.5w

The area of the rectangle is given by "lw", so

A = lw

Substituting the value of "l" from the first equation into this second equation:

A = (300 - 1.5w)w

A = 300w - 1.5w²

Thus, the area of the rectangle is a function of its width and can be expressed as Area = 300w - 1.5w².

To find value of w with maximum area, dA/ dw = 0

300 - 3w = 0

w = 100

Therefore, l = 300 - 1.5*100

l = 150

--The question is incomplete, answering to the question below--

"A rancher who wishes to fence off a rectangular area finds that the fencing in the east-west direction will require extra reinforcement due to strong prevailing winds. Because of this, the cost of fencing in the east-west direction will be $12 per (linear) yard, as opposed to a cost of $8 per yard for fencing in the north-south direction. Find the dimensions of the largest possible rectangular area that can be fenced for $4800, express the area of the rectangle as a function of its width."

The exact length (in inches) of the arc of a circle formed by given angle (in radians) and radius  is 5.233 inches.

The radius of a circle and the central angle determine the length of an arc. We are aware that given an angle of 360 degrees, the arc length corresponds to the circumference. Thus, the arc length is determined by multiplying the radius by the Centre angle (in radians).

Arc length = radius x angle(in radians)

Radius = 2 inches

Angle = 5pi/6 radians

Arc length = 2 x (5pi/6)

                = 5.233

Hence, the arc length is 5.233 inches.

You can only convert 1/6 to a decimal probability and round to 2 decimal places if you include the percentage sign (%) at the end.

When converting fractions to decimal probabilities, it is important to include the percentage sign (%) at the end. This is because when converting a fraction to a decimal, the result is not a whole number, but a decimal probability. For example, 1/6 can be written as a decimal probability of 0.17, but it is usually written as 0.17% to indicate the probability of an event occurring. The percentage sign is essential for students to understand that the decimal is a probability, rather than an incorrect answer. Percentage sign also allows the decimal to be rounded to two decimal places, giving a more precise answer. Without the percentage sign, the decimal will appear to be a whole number, which is not the correct answer.

There are 3 feet in 1 yard,

So 160 feet is the same as 160 / 3 = 53.333 yards.

Then we'll multiply the length by the width: 100 * 53.333 = 5333.33 square yards.

Therefore, the area of the football field is 5333.33 square yards.

The measure of angle K and L in the first figure is ∠L = 23 degrees and ∠K = 157. Second figure, the measure of ∠K = ∠L = 70 degrees.

A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.

For figure 2 the two lines are parallel to each other, and the line that meets the parallel line at points at M and L are from two equal lines.

Hence, the angle suspended by both are equal, that is:

∠L = ∠M

∠L = 23 degrees.

Now, the ∠K and ∠J are created by two parallel lines; hence they are equal:

∠K = ∠J = x

The sum of interior angles of a quadrilateral is 360, so:

∠L + ∠M + ∠J + ∠K = 360

23 + 23 + x + x = 360

46 + 2x = 360

2x = 360 - 46

x = 157

Hence, the measure of angle K and L is 157 and 23 respectively.

For the second figure, the angle K and L are created by equal length of segments.

∠K = ∠L = x

The sum of interior angles of a quadrilateral is 360, so:

∠L + ∠M + ∠J + ∠K = 360

x + 90 + 130 + x = 360

2x + 220 = 360

2x= 360 - 220

x = 70
