Step-by-step explanation:

the area is

baseline × height.

remember, 2 lengths are multiplied.

since both figures are similar to each other, it means that both lengths are changed by the same scaling factor.

18 × f = 63

f = 63/18 = 7/2

this factor f applies (as mentioned) to the baseline AND to the height.

therefore, the area changes by f×f = f² = 49/4.

that means the area of the larger figure is

216 × 49/4 = 54 × 49 = 2,646 yd²

The simplified form of the polynomial is \(-(a^2 / (6b^3)).\)

Polynomials are algebraic expressions that consist of variables and coefficients. The variables are often referred to as "indeterminates." The word polynomial comes from the terms "poly" and "nomial," which mean "many" and "terms," respectively. When you combine exponents, constants, and variables using mathematical operations such as addition, subtraction, multiplication, and division (excluding division by a variable), you get a polynomial. Depending on the number of terms it has, a polynomial can be categorized as a monomial, binomial, or trinomial.

To simplify this expression, we can use the following rules of exponents:

\(a^m/a^n = a^{(m-n) }\)(when the bases are the same)

\(a^{-m} = 1/a^m\\(1/b^m) = b^{-m}\)

Using these rules, we can simplify the expression as follows:

\(-6a^3b^{-1}/36ab^2 = - (6/36) \times a^{(3-1)} \times b^{(-1-2)}\\\\= - (1/6) \times a^2 \times b^{(-3)}\\\\= - (a^2 / (6b^3))\)

Therefore, the simplified form of the expression is \(-(a^2 / (6b^3)).\)

Explanation:

For these questions, we'll use the inscribed angle theorem. This says that the inscribed angle is half the measure of the arc it cuts off. An inscribed angle is one where the vertex of the angle lies on the circle, as problem 1 indicates.

For problem 1, the arc measure is 80 degrees, so half that is 40. This is the measure of the unknown inscribed angle.

Problem 2 will have us work in reverse to double the inscribed angle 42 to get 84.

-------------------

For problem 3, we need to determine angle DEP. But first, we'll need Thales Theorem which is a special case of the inscribed angle theorem. This theorem states that if you have a semicircle, then any inscribed angle will always be 90 degrees. This is a handy way to form 90 degree angles if all you have is a compass and straightedge.

This all means that angle DEF is a right angle and 90 degrees.

So,

(angle DEP) + (angle PEF) = angle DEF

(angle DEP) + (35) = 90

angle DEP = 90 - 35

angle DEP = 55

The inscribed angle DEP cuts off the arc we want to find. Using the inscribed angle theorem, we double 55 to get 110 which is the measure of minor arc FD.

The main difference between an area variance and a use variance is that area variance allows for an exception to zoning regulations related to the physical characteristics of a property, while use variance allows for an exception to regulations related to the intended use of a property.

An area variance is typically granted when a property owner is unable to comply with zoning regulations related to setbacks, building height, lot coverage, or other physical characteristics of a property.

In contrast, a use variance allows a property owner to use their property for a purpose that is not permitted under the current zoning regulations. This may include using a residential property for commercial purposes or using a commercial property for residential purposes.

Use variances are generally more difficult to obtain than area variances, as they require a showing of a unique hardship or practical difficulty that cannot be addressed through other means.

The maximum volume of the cylinder is 27147.355 cm² at the maximum point.

What is volume of cylinder?

The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula r2h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. The substance could be a liquid amount or something else that can be evenly put into the cylinder.

The formula for the volume of the cylinder v = \(\pi r^2\)h,

To find the maximum volume of the cylinder we apply the condition of maxima \(\frac{dv}{dr}\)  = 0.

Let r cm be the radius and h cm be the height of the closed cylinder.

Then, Total surface area of the cylinder = \(2\pi r(r+h)\)

                                                   5000      = \(2\pi r^{2} +2\pi rh\)

                                                    h     =    \(\frac{5000-2\pi r^{2} }{2\pi rh}\)............(1)

Volume of the cylinder v = \(\pi r^2h\)

Substitute the value of h  in the above equation

                                      = \(\pi r^2\) × \(\frac{5000-2\pi r^{2} }{2\pi rh}\\\)

                                      = \(\frac{r}{2}\) ×  \(5000-2\pi r^2\)

                                   v = \(2500r-\pi x^{3}\) ..............(2)

Now, for the maximum volume of the cylinder   dv/dr= 0

                                                      \(\frac{d(2500r-\pi x^{3})}{dr}\)         =0

                                                            \(3\pi r^{2} =2500\)

                                                               \(r^{2} =\frac{2500}{3\pi }\)

                                                              r=\(\frac{50}{\sqrt{3\pi } }\)

                                                           r= 27147.355

Hence, The maximum volume of the cylinder is 27147.355 at the maximum point r= \(\frac{50}{\sqrt{3\pi } }\).

Dilation and rotation is a series of transformations that would produce a figure that is similar to the original figure but not congruent with it.

Transformation of dilation and rotation:

Rigid transformations, such as rotations, reflections, and translations, do not alter the size or shape of a figure; rather, they only move it. The congruence is preserved by these hard changes.

However, because dilation alters a shape's size, they are not hard transformations. The ratio of matching sides would be equal to the scale factor used in the dilatation; the form would remain the same, just the size would vary. This would provide us with a comparable but in congruent value.

The y-coordinate for the solution to the system of equations is -3.

What is a system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations. The intersection of two lines represents the system of equations' solution.

Given system of equations are,

6x + 11y = -3

4x + y = 17

To solve these equations, we must first remove x or y terms.

To do this we must make the removing term's coefficients the same.

In this case, let's remove y.

We are multiplying the second equation by 11. Then,

6x + 11y = -3

44x + 11y = 187

Now we will subtract the second equation from the first.

- 38x  = -190

x = 5

Now to find y, substitute x in any one of the equations.

6 * 5 + 11y = -3

11y = -33

y = -3

Hence the y-coordinate for the solution to the system of equations is -3.

The function in Excel that we should use to find a measurement M given a right-tail probability (or area) A is = NORM.INV(1-A, mu, sigma)

In order to find a measurement M given a right-tail probability A in Excel, we can use the NORM.INV function. The NORM.INV function in Excel returns the inverse of the normal cumulative distribution for a given probability.

The formula for NORM.INV function is:

= NORM.INV(1-A, mu, sigma)

where:

A is the right-tail probability (or area)

mu is the mean of the distribution

sigma is the standard deviation

The function returns the measurement M such that the right-tail area from M to infinity under the normal curve is equal to A.

Note - In some versions of Excel, the function may be called NORM.INV.RT instead of NORM.INV.

The set representing the equivalence relation r can be written as:

r = {(a, a), (a, b), (a, c), (b, a), (b, b), (b, c), (c, a), (c, b), (c, c), (e, e)}

Based on the given information, an equivalence relation r on the set A = {a, b, c, d, e} with two equivalence classes. Know that ard, brc, and erd.

To write out the equivalence relation r as a set, we can list all the ordered pairs that belong to the relation.

The equivalence relation r consists of all the ordered pairs (x, y) such that x and y are related (i.e., belong to the same equivalence class). Since we have two equivalence classes, let's denote them as [a] and [e].

The equivalence class [a] contains the elements a, b, and c, and the equivalence class [e] contains the element e.

Thus, the set representing the equivalence relation r can be written as:

r = {(a, a), (a, b), (a, c), (b, a), (b, b), (b, c), (c, a), (c, b), (c, c), (e, e)}

Each ordered pair represents a relation between two elements in the set A based on the given equivalence relation r.

Area:-

the cosine of the angle between the planes is:

cos(theta) = (n1 . n2) / (|n1| |n2|) = 10 / (sqrt(3) * sqrt(42)) = 10 / (sqrt(126)) = (10/6) * sqrt(14) = (5/3) * sqrt(14)

To find the cosine of the angle between the planes, we need to find the normal vectors of both planes, and then use the dot product formula:

cos(theta) = (n1 . n2) / (|n1| |n2|)

where n1 and n2 are the normal vectors of the planes.

For the first plane x + y + z = 0, the coefficients of x, y, and z give us the normal vector <1, 1, 1>.

For the second plane x + 5y + 4z = 8, the coefficients of x, y, and z give us the normal vector <1, 5, 4>.

Taking the dot product of these vectors, we get:

<1, 1, 1> . <1, 5, 4> = 11 + 15 + 1*4 = 10

To find the magnitudes of the normal vectors, we can use the Pythagorean theorem:

|<1, 1, 1>| = sqrt(1^2 + 1^2 + 1^2) = sqrt(3)

|<1, 5, 4>| = sqrt(1^2 + 5^2 + 4^2) = sqrt(42)

The profit-maximizing quantity will take place where MR = MC—or at the last possible point before marginal costs start surpassing marginal revenue. The amount of goods produced at which marginal revenue equals marginal cost, or when MR = MC, is the decision that will maximize profits for the monopoly. If the monopoly produces less, MR > MC at given production levels, and the enterprise can increase profits by increasing output.

While a company produces more, MC > MR prevails, allowing it to increase profits even when it produces less overall. Therefore:

MC = change in total cost/change in quantity

      Change in quantity = 100 at each unit

      Change in total cost at 400 units = 2760 - 1960 = 800

      MC at 400 units  = 800/100 = 8

Under perfect competition, profit maximizing condition is where;

      P = MC

      At 400 units, P = MC = 8

Implies profit maximizing quantity is 400 units.

      Total revenue = Price x Quantity = 8 x 400 = $3200
