(6x ^ 3 - x ^ 2 - 14x + 5):(2x - 1)​

Answers

The final result of  algebra is: (6x^3 - x^2 - 14x + 5) : (2x - 1) = 3x^2 - x - 7 + 5/(2x-1)This is the simplified form of the given expression.

What is simplification?

Simplification is the process of making an expression or equation simpler and easier to understand or work with. In mathematics, simplification often involves combining like terms, removing unnecessary operations, or reducing the number of terms in an expression. The goal of simplification is to obtain an equivalent expression that is clearer, more manageable, and easier to interpret.

Here ,

is the step by step process:

(6x ^ 3 - x ^ 2 - 14x + 5):(2x - 1)

Step 1: Divide 6x^3 by 2x and write the quotient 3x^2.

Step 2: Multiply the denominator (2x - 1) by the quotient (3x^2)

Step 3: Subtract the result from the numerator and bring down the next term of the numerator ( x^2)

Step 4: Repeat the process by dividing the x^2 by 2x and write the quotient -x.

Step 5: Multiply the denominator (2x - 1) by the quotient (-x)

Step 6: Subtract the result from the numerator and bring down the next term of the numerator ( -14x)

Step 7: Repeat the process by dividing the -14x by 2x and write the quotient -7

Step 8: Multiply the denominator (2x - 1) by the quotient (-7)

Step 9: Subtract the result from the numerator and bring down the next term of the numerator (5)

Step 10: We can see that the degree of the remainder is less than the degree of the denominator so we can write the remainder as 5/(2x-1)

So the final result is:(6x^3 - x^2 - 14x + 5) : (2x - 1) = 3x^2 - x - 7 + 5/(2x-1)

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.

What is volume of cone?

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.

How to find the side of a triangle?

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

Using equation, the number of large drinks is 126.

How to find the number of large drinks sold?

A drink stand is selling small drinks for $2 each and large drinks for $4 each. One day, a total of 150 drinks were sold for $552.

The number of large drinks sold can be calculated as follows:

Using equation,

let

x = number of small drinks

y = number of large drinks

Hence,

2x  + 4y = 552

x + y = 150

multiply equation(ii) by 2

2x  + 4y = 552

2x + 2y = 300

subtract equation(ii) from equation(i)

2y = 252

divide both sides by 2

y = 252 / 2

y = 126

Therefore,

number of large drinks = 126

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.

How to find the Median?

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.

Explanation

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

In Nepal, some students paddle a kayak to get to school. Suppose it takes one student 1/4 hour to paddle 1/2 mile How far would the student paddle in `t` hours at this speed?
what is t

Answers

The distance that the student can travel in "t" hours if the speed is constant is:

distance = (2 mi/h)*t

How far would the student paddle in `t` hours at this speed?

Here we need to remember the relation between time, distance, and speed:

distance = time*speed.

Solving for speed, we will get:

Speed = distance/time

Here, we know that the student can travel 1/2 of a mile in 1/4 of an hour, then we have:

distance = 1/2 of a miletime = 1/4 of an hour.

With that, we can find the speed:

speed = (1/2 of a mile)/(1/4 of an hour) = 2 miles per hour.

Then the distance that the student can paddle in "t" hours is written as:

Let V be the set of all positive real numbers. Define + by U+V = UV-1 and . by C.V = V. Is V a vector space? Explain?

Answers

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.

What is compound interest rate?

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]
