Step-by-step explanation:

To find the roots of a polynomial, it is often useful to find the Factors of the polynomial.

Based on the given expression representing each angle, the value of x is 47 and each angles are 135° and 45° respectively.

Based on the given diagram; the angles represented by the expression are referred to as supplementary angles.

So, we can find the unknown variable x by adding the expressions and equating it to 80°

(3x - 6) + (x - 2) = 180

3x - 6 + x - 2 = 180

combine like terms

3x + x - 6 - 2 = 180

4x - 8 = 180

Add 8 to both sides

4x = 180 + 8

4x = 188

divide both sides by 4

x = 188/4

x = 47

Therefore, the respective angles are;

3x - 6

= 3(47) - 6

= 141 - 6

= 135°

x - 2

= 47 - 2

= 45°

The surface area of the cone with the given parametric equation is (4π + 4π√2) square units.

The parametric equations describe a cone that is generated by rotating a line segment in the xy-plane about the x-axis. The result is a 3-dimensional surface that has a circular base with radius 2 and a height of 2.

The surface area of the cone can be calculated using the formula:

A = πr^2 + πrs

where r is the radius of the circular base and s is the slant height.

The slant height is equal to the distance from the center of the circular base to the tip of the cone, which can be calculated using the Pythagorean theorem: s = √(h^2 + r^2), where h is the height of the cone.

Therefore, for this cone with radius 2 and height 2, the surface area can be calculated as:

A = πr^2 + πrs

= π * 2^2 + π * 2 * √(2^2 + 2^2)

= 4π + 4π√2

The length longer diagonal is 174 cm.

In a rhombus, the diagonals bisect each other as well as the the vertex angles and adjacent angles are supplementary

So assuming that the 70 degree angle is opposite the 122 cm diagonal, we have

(1/2 length of the shorter diagonal) / sin (35)  = (1/2 length of the longer diagonal) / sin(55)

Multiply both sides by 2

( length of the shorter diagonal) / sin (35)  = ( length of the longer diagonal) / sin(55)

Multiply both sides by sin(55).

Length of the longer diagonal = sin (55) (122 cm) / sin (35) = 174 cm

The mean of the 400 richest Americans as of September 19, 2012 is $4.25 billion.

The mean of the 400 richest Americans is calculated by summing up all of the net worth of each person on the list, and then dividing it by the total number of people on the list. The formula used to calculate the mean is:

Mean = (Sum of Net Worth) / (Total Number of People on the List)

For example, on September 19, 2012, the total net worth of the 400 richest Americans was $1.7 trillion. If we divide this by the total number of people on the list (400), then the mean net worth of the 400 richest Americans is $4.25 billion.

The total surface area of the hexagonal pyramid is 237.5 in²

An expression that depicts the relationship between two or more numbers and variables is called an equation. Depending on the degree, an equation may be linear, quadratic, cubic, or another type.

A solid figure's surface area is calculated by summing up all of its distinct surfaces.

Given the hexagonal pyramid with a base of 6 inches and each isosceles triangle having a height of 8 inches. Hence:

Area of pyramid base = 93.5 in²

The lateral face has 6 triangle faces, hence:

Area of each lateral face = 1/2 * base * height = 0.5 * 8 * 6 = 24 in²

Total area of lateral face = 6 * 24 in² = 144 in²

Total surface area = 144 in² + 93.5 in² = 237.5 in²

The average value of the function f(x) = x² - 8x + 6 on [0, 4] is 38.

The two primary divisions of calculus, differential calculus and integral calculus, are concerned with rates of change and slopes of curves.

By dividing the definite integral of the function over the interval by the length of the interval, one can determine the average value of a function over the interval [a, b].

The function in this instance is f(x) = x3 - 8x + 6, and the range is [0, 4]. Using the definite integral of x3 and the definite integral of -8x, one can determine the definite integral of the function across the interval:

[tex]\int\limits^0_4 {x^{3} - 8x + 6 } \, dx[/tex]

= [tex]\frac{x^4}{4} - \frac{8x^2}{2} + 6x[/tex]

evaluated at x = 4 - x = 0 = [tex]0 - \frac{4^{4} }{4} - \frac{8.4^2 }{2} + 6.4\\[/tex]

The length of the interval is b - a = 4 - 0 = 4. Hence, the average value of the function over the interval is given by:

The statement "if v in R3 and v · v = 0, then v is the zero vector" is true

In mathematics, a vector is an ordered tuple of numbers or scalars that can be used to represent a quantity that has both magnitude and direction. Vectors are used to model physical quantities such as displacement, velocity, and force, among others.

Here we have given that if v in r 3 and v · v = 0, then v is the zero vector.

It is true because if the dot product of a vector with itself is zero, it means that the magnitude of the vector is zero and thus it is the zero vector. Understanding the concept of a zero vector and its relationship with other vectors is important in mathematics and physics.

Answer:

[tex]\boxed{21.691} \; feet[/tex]

Step-by-step explanation:

See attached figure

The power cable going south first by 50 feet and then going west by 30 feet form the legs of a right triangle.

The diagonal which is the shortest distance between start and end points can be computed by the Pythagorean theorem

[tex]c^2 = a^2 + b^2[/tex]

where c is the hypotenuse and a, b the other two sides

Plugging in values for a = 50 and b = 30 we get

[tex]c^2 = 50^2 + 30^2\\\\c^2 = 2500 + 900\\\\c^2 = 3400\\\\c = \sqrt{3400}\\\\c = 58.3095 \;feet[/tex]

The cable length if going south and then west will be 50 + 30  = 80 feet

So cable length saved = 80 - 58.3095 = 21.6905

Rounded to 3 decimal places this would be 21.691 feet

Answer:

By using the Pythagorean Theorem, we can calculate that the diagonal of the city block is approximately 58.3 feet long. This means that the power company could save 7.3 feet of powerline cable by running the powerlines across the diagonal of the city block, instead of around the south and west sides.

Surface area of the cube can be S = 6x², if the side length of the cube is 7.7 cm, the surface area would be is S = 6(7.7)² = 391.16.

The surface area of an object refers to the total area of its exposed outer surface. It is a measure of the amount of space that an object's surface covers. Surface area is a two-dimensional concept, and is different from the object's volume, which is a three-dimensional concept.

The surface area of an object depends on its shape, and can be calculated using mathematical formulas specific to different shapes. For example, the surface area of a cube is the sum of the areas of its six faces, while the surface area of a sphere is given by the formula 4πr^2, where r is the radius of the sphere.

Surface area is an important concept in a variety of fields, including physics, chemistry, and engineering. In physics, it is used to calculate the heat transfer between objects, while in chemistry it is used to calculate the amount of reactant needed to cover a given surface area in a reaction. In engineering, surface area is important in the design of heat exchangers, reactors, and other equipment where heat or chemical reactions take place on surfaces.

The volume of the solid is approximately equal to 441.75 π cubic units.

The volume of the solid can be found using the disk method of integration. To set up the integral, consider a disk of height 'h' and radius 'r' at position y. The volume of this disk is given by πr^2h, and the radius 'r' is equal to 9 - y. Therefore, the volume of the solid is given by the following triple integral:

[tex]V = \int\{\pi(9 - y)^2dy} \int\,dh \int\,dx[/tex]

Where the limits of integration are:

So, the final expression for the volume is:

[tex]V = \int\limits^{9}_{y=0} \int\limits^{x}_{h=0} \int\limits^{9}_{x=0} \pi (9 - y)^2 dh dx dy[/tex]

Evaluating the integral gives:

[tex]V = \pi \int\limits_{y=0}^{9} (9 - y)^2dy \int\limits_{h=0}^{x} dh \int\limits_{x=0}^{9} dx[/tex]

[tex]= \pi \int\limits_{y=0}^{9} (81 - 18y + y^2)dy \int\limits_{h=0}^{x} dh \int\limits_{x=0}^{9} dx[/tex]
