. if v in r 3 and v · v = 0, then v is the zero vector. is it true or false? explain your answer
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.

What is meant by Reflection?A reflection in mathematics is an isometric mapping from a Euclidean space to itself with a set of fixed points called the axis or plane of reflection. A figure's image created by a reflection is a mirror image of that figure in the axis or plane of reflection. A flip is the term for a reflection in geometry. The shape is mirrored in a reflection. The line of reflection is a line across which an image will reflect.

The parametric equationsx = u, y = ucosv, z = usinv, with 0 ≤ u ≤ 2, 0 ≤ v ≤ 2π represent the cone that results when the line y = x (where 0 ≤ x ≤ 2) in the xy−plane is revolved about the x−axis. Sketch the cone, and calculate its surface area.
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

[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.
the shorter diagonal of a rhombus with 70 degrees is 122 cm long, how long is the longer diagonal
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
Therefore, the length of the longer diagonal is 174 cm.

find the average value of the function f(x) = x3 8x 6 on [0, 4].
The average value of the function f(x) = x² - 8x + 6 on [0, 4] is 38.
Describe calculus.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]
= - 24
The length of the interval is b - a = 4 - 0 = 4. Hence, the average value of the function over the interval is given by:

use the general slicing mothod to find the volume of the following solid. The solid with a semicircular base of radius 9 whose cross section is perpendicular to the base and parallel to the diameter are squares. Place the semicircle on the xy-plane so that its diameter is on the x-axis and it is centered on the y-axis. Set up the integral that gives the volume of the solid. Use increasing limits of integration.
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:
For x: 0 to 9 (since the square cross-section has side length of 9)For h: 0 to x (since the height of the disk cannot be greater than the distance from the xy-plane)For y: 0 to 9 (since the radius of the semicircle is 9)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]
[tex]= \pi \int\limits_{y=0}^{9} (81 - 18y + y^2)dy (x^2/2) dx[/tex]
[tex]= \pi /2 \int\limits_{y=0}^{9} (81 - 18y + y^2)dy (x^2) dx[/tex]

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
