No, V is not a vector space with the operations defined in this way. Because the operations defined in this question do not satisfy the properties required for V to be a vector space.

A vector space is a collection of objects (vectors) that can be added together and multiplied ("scaled") by numbers, called scalars. These operations must satisfy certain properties to be considered a vector space.

For example, one of the properties is the associativity of vector addition, which means that (u + v) + w = u + (v + w) for any vectors u, v, and w in V. However, with the given definition of +, we have (U + V) + W = (UV-1) + W = U(VW-1) which is not equal to U + (V + W) = U(VW-1)

Another property is the distributivity of scalar multiplication over vector addition, which means that c(u + v) = cu + cv for any scalar c and any vectors u and v in V. But with the given definition of ., we have C(U+V) = C(UV-1) which is not equal to C.U + C.V = CUV-1

Furthermore, with the definition given the additive identity and the existence of additive inverse are not guaranteed.

Therefore, V is not a vector space with the operations defined in this way.

What is Geometric Progression ?

Geometric progression can be defined as the sequence of numbers in which the common ratio between any consecutive numbers is same.

Given sequence ,

1/324  , 1/108 , 1/36 , 1/12

Lets check whether they are in Geometric sequence or not.

So,

r = 1/108  /  1/324

r = 324/108

r = 3

And

r = 1/36  /  1/108

On solving the provided question, by LCM after 2520 minutes, all 3 movies will begin at the same time.

The number that is the smallest of two or more natural numbers' common multiples is known as the Lowest Common Multiple (LCM) in mathematics.

IF we look from mathematical point  of view, the question is just asking what is the smallest numbers that is divisible by 120, 140 and 90, which is the L.C.M of these 3 number.

For instance, 12 is the least frequent multiple of 4 and 6. As a result, 12 is the lowest common multiple such that its elements are 4 and 6.

If we look at what the question ask, all the movies will begin at the same time if all the multiples of 120, 140 and 90 have a number in common and should be smallest.

Hence, after solving for L.C.M., we get 2520 as the L.C.M.

By ranking the wages of a group of employees in descending order, you may determine the median base salary by finding the wage that is in the Middle of the distribution . 50 percent of earnings fall below the median, while 50 percent of salaries rise above the median.

The average of a set of numbers is known as the mean. If there are five salaries involved and the mean is $360, the total can be calculated by

Average = Total / number

Total = (Average)(Number)

Total = $360 * 5 = $1800

Four of the wages are spoken for, so we add them up and take $1800 out of the equation to get our result.

so $340 + $340 + $345 + $425 = $1450

and $1800 - $1450 = $350

Omar needs to invest $9,788, to the nearest dollar, for the value of the account to reach $32,400 in 20 years

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

x = P (1+r/n[tex])^{nt}[/tex]

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for

Given:

Omar is going to invest in an account paying an interest rate of 6% compounded monthly.

A =  $32,400 in 20 years

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 per year,

Then, solve the equation for P

P = A / (1 + r/n[tex])^{nt}[/tex]

P = 32,400.00 / (1 + 0.06/12[tex])^{(12)(20)}[/tex]

P = 32,400.00 / (1 + 0.005[tex])^{240}[/tex]

P = $9,787.91

P = $9788  to the nearest dollar.

The value of y is 58 and RS is 55.25 and ST is 17.5.

Equation is an expression that consists of variables, constants, and operators, and expresses a relationship between them. It is a mathematical statement that two expressions are equal. Equations can be used to solve a wide variety of problems in mathematics, science, engineering, and other fields. Examples of equations include the Pythagorean Theorem, the equation of a circle, and the equation of a line. Equations can be written in a variety of forms, such as symbolic, graphical, and numerical.

The value of y can be found by solving the equation 8y+4=58. By subtracting 4 from both sides, we get 8y=54.

Dividing both sides by 8, we get y=6.75.

Therefore, RS=8y+4=8(6.75)+4=55.25 and

ST=2y+4=2(6.75)+4=17.5.

 line that intersects two or more lines at a distinct points is known as transversal line.

A contour map/ plot is a way of representing a function with a two-dimensional input and a one-dimensional output.

Contours are obtained by intersecting the surface with the horizontal plane using the equation z = c. So the contour equation at height c is f(x,y) = c.

There are three types of contour lines displayed on the map:

Intermediate, Index, Supplement. The index line is the thickest contour line, and the points along the line are usually function numbered. Contours do not branch or split. Page 5 Steep slopes are represented by dense contour lines. Contour lines never intersect, but they can touch.

The length of the triangle DEF f is 4.3 units.

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

The sine law can be used to find the side of a triangle. Therefore, let's find the side f of the triangle using sine law.

Therefore,

a / sine A = b / sin B = c / sin C

Hence,

e / sin E = f / sin F

E = 180 - 104 - 52

E = 24 degrees

Therefore,

1.8 / sin 24 = f / sin 104

cross multiply

1.8 sin 104 = f sin 24

divide both sides by sin 24

f = 1.8 sin 104  / sin24

f = 1.8 × 0.97029572627 / 0.40673664307

f = 1.7465323073 / 0.40673664307

Step-by-step explanation:

we add 6.8% of the population to the city each year

city population in year x + 1 = city population in year x + 6.8% of city population in year x = city population in year x + 0.068 * city population in year x = 1 * city population in year x + 0.068 * city population in year x = 1.068 * city population in year x

we multiply the population by 1.068 each year to get the next year's population

thus, over a period of y years, we would multiply the population by 1.068 y times.

start = 34000 in 1937

difference in years = 1970 - 1937 = 33

final amount = 34000 * 1.068 33 times = 34000 * 1.068^33 = 298078.228074

The volume of a cone is given by the formula V = (1/3) * π * r^2 * h Where the volume of this cone is approximately A:2016.

The volume of a cone is a measure of the amount of space inside the cone.

It is calculated using the formula: V = (1/3) * π * r^2 * h, where V is the volume, r is the radius of the base of the cone, h is the height of the cone, and π is the mathematical constant pi (approximately equal to 3.14).

The volume of the cone is the amount of space inside the cone, and is measured in cubic units (such as cubic centimeters, cubic meters, etc.).

From the diagram, we can see that the radius of the base of the cone is 4 and the height is 8. Plugging these values into the formula, we get:

V = (1/3) * π * 4^2 * 8

V = (1/3) * π * 16 * 8

V = (1/3) * 64π

The volume of this cone is approximately A:2016.
