Answer:

[tex]49x^{6}[/tex][tex]y^{8}[/tex]

Step-by-step explanation:

1. Factor 2401 into its prime factors

          2401 = 74

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          2401 = 74

No factors remain inside the root!!

To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          49 = 72

At the end of this step the partly simplified SQRT looks like this:

        49√(x^12y^16)

2. Rules for simplifying variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

     (3.1) √(x8)=x4

    (3.2) √(x-6)=x-3

   (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

     (4.1) √(x5)=x2•√(x)

    (4.2) √(x-7)=x-3•√(x-1)

Applying these rules to our case we find out that

     SQRT(x12y16) = x6y8

Combine both simplifications:

 sqrt (2401x12y16) =

       49x6y8

A country will roughly double its gdp in twelve years if its annual growth rate is 5.8  using the rule of 70.

The rule of 70 is used to determine the time it takes a country to double it growth rate.

To double in 12 years =70/12 = 5.8

Therefore, A country will roughly double its gdp in twenty years if its annual growth rate is 5.8  using the rule of 70.

A measure of the rise in the value of an investment or revenue stream over the course of a year is the annual growth rate, often known as the "simple growth rate" or "average annual growth rate (AAGR)".

The formula for calculating annual growth rate divides the total value of annual growth at the beginning of the year by the total value of that growth at the end of the year.

The statistical method known as analysis of variance (ANOVA) is used to examine how different means differ from one another.

When you only run an omnibus/overall anova without any post-hoc tests, you will be unable to determine which of the groups are statistically different from each other. This is because an omnibus/overall anova simply tells you whether there is a significant difference between any of the groups, but does not tell you which groups are different. Follow up tests are needed to determine which of the groups are statistically different from each other.

With $190, a maximum of 12 people can visit the theme park, where admission costs $15.25 per person and parking costs $7.

In mathematics, "inequality" refers to a connection between two expressions or values that are not equal to one another. The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in lieu of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x values for which the inequality holds true is what we are most interested in.

Here,

The total amount they can spend=$190

Cost of parking=$7

Cost of ticket per person=$15.25

Let the number of person be x,

15.25x+7≤190

Brace's taxable income is $50,000.

It is given to us that -

Brace Inc. owns 90% of West common stock

Brace generated $50,000 operating income

and, Brace received $10,000 dividends from West

We have to find out Brace's taxable income.

Taxable income can be defined as the income (income amount) of an individual or business that federal or state government agencies use as the basis for determining the taxes owed on them.

The correct formula representing taxable income can be stated as -

A. Taxable income = Total income - Exclusions - Adjustments to income - Deductions - Exemptions.

B. Taxable income = Gross income - Adjustments to income - Deductions - Exemptions.

C. Taxable income = Adjusted gross income - (Deductions + Exemptions).

Since, it is mentioned that Brace Inc. owns 90% of West common stock, it can be determined that the stock share is more than 80%.

This implies that there will be 100% deduction in the value of taxable income since the stock share is more than 80%.

Thus, Brace's taxable income is $50,000.

Inequality (C) -3.2 + 1.5n ≤ 8.6 correctly represents the sentence "the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6."

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.

Both mathematical phrases, equations, and inequalities are created by connecting two expressions.

The equal sign (=) indicates that two expressions in an equation are believed to be equivalent.

The symbols >, <, ≤ or ≥ indicate that the two expressions in inequality are not always equal.

So, the sentence we have is:

the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6

Which can be written in inequality as:

-3.2 + 1.5n ≤ 8.6

Therefore, inequality (C) -3.2 + 1.5n ≤ 8.6 correctly represents the sentence "the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6."

Converse: If it is a dog, it is a beagle. This is a false statement, since a dog can be any other breed (ex. Pomeranian).

Inverse: If it is not a beagle, it is not a dog. Again a false statement, since if it is a different breed, it is a dog despite not being a beagle. For example, it could be a Pomeranian.

Contrapositive: If it not a dog, it is not a beagle. This is true, since if something is not a dog, it won't be any particular breed of dog either (and it won't be a beagle).

Answer: y=(1x)^x + 5000

Step-by-step explanation:

So the original equation is y=mx + b

And we know that each year the house increase by 5000, so the b is 5000

For the x which is the slope, we don't know what the slope is so we just say it as x and the ^x is for the number of years, let's say 3 years then it is ^3 and keep increasing like that up.

The equation of a line perpendicular to y = (-2/3)x - 7 is  y = (3/2)x + 17.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know lines perpendicular to each other have slopes that are negative reciprocals of each other.

So, the slope of the perpendicular line to the given line y = (-2/3)x - 7 is (3/2)

which passes through the point (-4, 11) is,

11 = (3/2)(-4) + b.

b = 11 + 6.

b = 17.
