The area of the rhombus is 16√39 sq. cm.

A four-sided polygon with equal-length sides is known as a rhombus. A rhombus is an unique kind of parallelogram, like a square, in which the opposing sides are parallel and congruent. Yet, a rhombus lacks right angles, unlike a square.

Given that, sides = 10cm and the diagonal = 16 cm.

Using the Pythagorean theorem, we can find the length of the other diagonal as follows:

a^2 + b^2 = c^2

(10/2)^2 + b^2 = 16^2/4

25 + b^2 = 64

b^2 = 39

b = √39

The length of the other diagonal is 2*√39 cm.

Now, we can use the formula for the area of a rhombus:

A = (d1d2)/2 = (162√39)/2 = 16√39

Hence, the area of the rhombus is 16√39 sq. cm.

The area of the rhombus is approximately 62.4 cm².

A rhombus is a quadrilateral with four sides of equal length. It is also known as a diamond or a lozenge. A rhombus has two pairs of parallel sides, and opposite angles are equal to each other. The diagonals of a rhombus bisect each other at right angles, meaning they cut each other in half and form a right angle at their intersection point.

The properties of a rhombus are similar to those of a square, but unlike a square, a rhombus does not have right angles. However, a square can be considered a special case of a rhombus, where all four angles are right angles.

The area of a rhombus can be calculated using the formula:

Area = (diagonal 1 x diagonal 2) / 2

where diagonal 1 and diagonal 2 are the lengths of the two diagonals of the rhombus.

Let's use the Pythagorean theorem to find the length of the shorter diagonal. We know that a rhombus has two pairs of congruent right triangles. Let's call the length of the shorter diagonal d.

Using Pythagorean theorem:

(10/2)² + (d/2)² = (16/2)²

5² + (d/2)² = 8²

25 + (d/2)² = 64

(d/2)² = 39

d/2 = √(39)

d = 2 * √(39)

Now we can use the formula for the area of a rhombus:

Area = (diagonal1 * diagonal2) / 2

Area = (10 * 2 * √(39)) / 2

Area = 10 * √(39)

Therefore, the area of the rhombus is approximately 62.4 cm².

To determine the sample size needed to estimate the proportion of supporters with a margin of error of 2.3% and a 90% confidence level,

we can use the formula:
n = (Z^2 * p * (1-p)) / E^2
Where:
- n is the sample size
- Z is the Z-score for the desired confidence level (for 90% confidence, Z = 1.645)
- p is the estimated proportion of supporters (if we have no prior knowledge, we can use 0.5 as a conservative estimate)
- E is the desired margin of error (2.3% or 0.023)

Plugging in the values, we get:
n = (1.645^2 * 0.5 * (1-0.5)) / 0.023^2
n = 752.3
Since we cannot have a fraction of a person, we round up to the nearest whole number to get a sample size of 753.

Therefore, a sample size of 753 is needed to estimate the proportion of supporters with a margin of error of 2.3% and a 90% confidence level.

The mean of the given probability distribution is 2.8.

To find the mean, we multiply each possible value of X (the number of adults with a college degree) by its corresponding probability, and then add up the products.

So, the mean is:

(0)(0.0081) + (1)(0.0756) + (2)(0.2646) + (3)(0.4164) + (4)(0.2401) = 2.8

This means that on average, out of 4 randomly selected adults in the town, 2.8 of them will have a college degree. This is a useful measure of the central tendency of the probability distribution, as it gives us an idea of what to expect if we were to repeat this process of randomly selecting 4 adults many times.

It's important to note that the mean is not necessarily a value that is actually observed in the data, but rather a summary statistic that tells us about the distribution as a whole. In this case, it tells us that the distribution is slightly skewed towards higher values, since the mean is greater than the median (which would be the value of X with cumulative probability of 0.5, or 2 in this case).

The translated function from y=|x| that has a shrink of ( 1)/(4), a reflection over the x-axis and a vertical shift of 8 units down is y=-|(1)/(4)x|-8.

If f(x) is a function, then a translated function can be defined by adding or subtracting a constant value a to the variable x inside the function, resulting in a new function g(x) = f(x-a) or g(x) = f(x+a), respectively.

To create the translated function from y=|x|  we can follow these steps:
1. Shrink the function by multiplying the input by (1)/(4): y=|(1)/(4)x|
2. Reflect the function over the x-axis by multiplying the output by -1: y=-|(1)/(4)x|
3. Shift the function 8 units down by subtracting 8 from the output: y=-|(1)/(4)x|-8,

To find the level of production that maximizes the manufacturer's total revenue, we need to find the quantity, q, that maximizes the revenue function, R(q) = p*q.

First, we need to find the revenue function by substituting the demand function for p in the revenue function:
R(q) = p*q = (−0.13q+156)*q = -0.13q^2 + 156q
Next, we need to find the quantity that maximizes this function. To do this, we can take the derivative of the revenue function and set it equal to zero:
R'(q) = -0.26q + 156 = 0
Solving for q, we get:
q = 600
This means that the quantity that maximizes the manufacturer's total revenue is 600 units.
To find the maximum revenue, we can plug this quantity back into the revenue function:
R(600) = -0.13(600)^2 + 156(600) = 46,800

Therefore, the maximum revenue is $46,800.

Therefore, the lengths of the sides of quadrilateral HIJK are √(65),  13, √(65), and √(52).

A quadrilateral is a polygon with four sides and four vertices. The sum of the interior angles of a quadrilateral is always equal to 360 degrees. There are many different types of quadrilaterals, including squares, rectangles, parallelograms, trapezoids, rhombuses, and kites. Each type of quadrilateral has its own unique properties, such as having four equal sides (square), having opposite sides parallel (parallelogram), or having two pairs of equal adjacent sides (kite). Quadrilaterals can be classified based on their sides, angles, or both.

Here,

The point H has coordinates (-5, 6), which means it is located 5 units to the left of the y-axis and 6 units above the x-axis. The point I has coordinates (3, 4), which means it is located 3 units to the right of the y-axis and 4 units above the x-axis. The point J has coordinates (0, -8), which means it is located at the intersection of the x-axis and the y-axis, but 8 units below the x-axis. Finally, the point K has coordinates (-7, -2), which means it is located 7 units to the left of the y-axis and 2 units below the x-axis.

We can see that HIJK is a general quadrilateral, meaning that it does not have any special properties like being a rectangle or a parallelogram. We can find the lengths of its sides and the measures of its angles by using the distance formula and the slope formula, respectively. The distance formula gives us the distance between any two points (x1, y1) and (x2, y2):

distance = √((x2 - x1)² + (y2 - y1)²)

The slope formula gives us the slope of a line passing through two points (x1, y1) and (x2, y2):

slope = (y2 - y1) / (x2 - x1)

Using these formulas, we can find that the lengths of the sides of HIJK are:

HI = √((3 - (-5))² + (4 - 6)²) = √(65)

IJ = √((0 - 3)² + (-8 - 4)²) = √(169) = 13

JK = √((-7 - 0)² + (-2 - (-8))²) = √(65)

KH = √((-7 - (-5))² + (-2 - 6)²) = √(52)

We can also find the slopes of the lines passing through each pair of adjacent vertices:

The slope of line segment HI passing through points H and I is:

(4 - 6) / (3 - (-5)) = -1/2.

The slope of line segment IJ passing through points I and J is:

(-8 - 4) / (0 - 3) = 4/3.

The slope of line segment JK passing through points J and K is:

(-2 - (-8)) / (-7 - 0) = 6/7.

The slope of line segment KH passing through points K and H is:

(6 - (-2)) / (-5 - (-7)) = 4/3.

The surface area of the cylinder with a height of 8 yards and a radius of 82.13 yards is  46,486.93 sq. yards.

What is a cylinder?

One of the most fundamental curvilinear geometric shapes, a cylinder has historically been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry. One of the fundamental three-dimensional shapes in geometry is the cylinder, which has two distant, parallel circular bases. At a predetermined distance from the centre, a curved surface connects the two circular bases. The axis of the cylinder is the line segment connecting the centres of two circular bases. The height of the cylinder is defined as the distance between the two circular bases.

Given,

The height of the cylinder = 8 yards

 The circumference of the cylinder = 515.79 yards

We are asked to find the surface area of the cylinder.

Now the formula to find the surface area of a cylinder is:

SA = 2πr( r+h)

where r = radius

      h = height

Radius can be found from the circumference formula

2πr = 515.79

r = 515.79/ 2π = 515.79 / (2*3.14) = 82.13 yards

Then,

SA = 2πr( r+h) = 2*3.14*82.13 ( 82.13+8) = 46,486.93 sq. yards

Therefore the surface area of the cylinder with a height of 8 yards and a radius of 82.13 yards is  46,486.93 sq. yards.

The circumference of the circle is approximately 31.4 cm to the nearest tenth.

Use this formula to get a circle's circumference:

C = 2πr

where C is the circumference, pi (roughly 3.14), is a mathematical constant, and r is the circle's radius.

If you have the diameter of the circle, you can find the radius by dividing the diameter by 2.

Once you have the radius, you can plug it into the formula to find the circumference.

For example, if the radius is 5 cm:

C = 2πr

C = 2 x 3.14 x 5

√25 - 16 = x

x = 3.

4) In this triangle:

Adjacent = x

Opposite = 5 yard

Hypotaneous = 13 yard

so, (13)² =  (5)² + (x)²
