As time passes, the amount of money in the account increases.

The amount in the account increases by $45.

The amount of money in the account when he started depositing is  $197.

A linear function is a function that has one independent variable and one dependent variable. A linear function increases at a constant rate over a period of time. When drawn on a graph, a linear function is usually a straight line.

The form of linear functions is:

y = a + mx

Where:

Looking at the given table, it can be seen that as time passes, the amount of money increases.

Rate of increase = (change in the amount of money) / change in the months

(557 - 467) / (8 - 6)

= 90 / 2

= $45

Amount in the account at the beginning = account balance at 6 months - (rate of increase x 6)

467 - (6 x 45)

467 - 270 = $197

To find

So, according to the question

we have,

We have to find the value in kilowatt / hours power for per year basis

So, We know

Days in one year = 365

power in 3 days = 12 kilowatt/hours

For calculate power in single day, we have to divide power in 3 days by 3.

So power in a single day  = 12/3 kilowatt/hours

                                          = 4 kilowatt/hours

Now we have to multiply days in one year with power in a single day

     power for per year basis

                              = days in one year x power in a single day

Now, putting the all values,

                            = 365 x 4 kilowatt/hours.

                            = 1460 kilowatt/hours.

The given statement exists true. If the measures of the base angles of an isosceles triangle are integers, then the sum of those angles is 2 times that integer, so the sum is an even number. The three angles added together must add to 180.

An isosceles triangle in geometry is one with at least two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

The characteristics of an isosceles triangle are as follows: There is an agreement between two sides. The base of an isosceles triangle refers to the third side of the triangle, which is unequal to the other two sides. The two angles that are opposite the equal sides line up perfectly.

If the measures of the base angles of an isosceles triangle are integers, then the sum of those angles is 2 times that integer, so the sum is an even number. The three angles added together must add to 180.

An even number plus an odd number will be an odd number, and 180 exists always even.

   The vertex, focus and directrix of the parabola y = x²/4 are:

  The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.

  The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.

  In this case we have an expression given by:

y = x²/4

   We must find the canonical equation:

(y - 0)² = 1/4 (x - 0)²

(x - 0)² = 4 (y - 0)²

has the form

(x - h)² = 4p(y - k)

  This means that the vertex of this parabola is

v = (h, k)

v = (0,0)

The range of the function g(x) = - 1 / 2 | x - 6 | + 1 is ( - ∞, 1].

We are given a function:

g(x) = - 1 / 2 | x - 6 | + 1

We need to find the range of the function.

Now, we can see that the tip of the function will be formed when | x - 6 | = 0

x - 6 = 0

x = 6

For x = 6, we have the value of g(x) as

g(x) = - 1 / 2 | 6 - 6 | + 1

g(x) = 0 + 1

g(x) = 1

Also, since - 1 / 2 is negative, the function will have range from negative infinity to 1.

So, the range of the function will become:

A = final amount

P = initial principal balance =  Rs8000

r = annual interest rate   =  [tex]6\frac{1}{2}[/tex]% = 0.065

t = time (in years) = 3 years

The F-value for the interaction is [tex]3.42[/tex]. It is determined by the interaction of gender and race.

What is F-value?

The calculation of the F-value is used on statistics in analysis of variance which is denoted as ANOVA. The calculated value is determined from the ratio of explained variance to unexplained variance. When the F-values in an ANOVA is higher that means the variance is higher in the sample.

The F-statistic value is also used in the regression analysis to calculate the mean between the population. It also depends on the null hypothesis and when the null hypothesis is true. That means the F-value is always close to one most of the time. It is named as F-value after Sir Ronald Fisher. The variance is the dispersion of the value.

Answer: Cynthia will receive $5,400, Moses will receive $8,100, John will receive $13,500

Step-by-step explanation:

       First, we will see how many "portions" the money is broken up into.

2:3:5 can become 2 + 3 + 5 = 10

       Next, we will see how much money each "portion" is worth using division.

$27,000 / 10 = 2,700

       Finally, we will multiply to see how much each person will receive.

2:3:5

2 * $2,700 = $5,400 [Cynthia]

3 * $2,700 = $8,100 [Moses]

5 * $2,700 = $13,500 [John]

Answer:

Cynthia's money = $5,400

Moses' money = $8,100

John's money = $13,500

Step-by-step explanation:

The full ratii of the money will be 2+3+5 = 10

Cynthia's ratio = 2 × $27,000

10

= 2 × 2,700

= $5400

Moses' ratio = 3 × $27,000

10

= 3 × 2,700

= $8100

John's ratio = 5 × $27,000

10

= 5 × 2,700

Using substitution method, the solution of the given system of equations is (-9, -26)

A system of equation can be solved using:

The given system of equations:

y = 3x+1   ............   (1)

2x - y = 8  .............. (2)

Notice the y variable is already isolated on the left side. Therefore, we can immediately use the substitution method.

Substitute y = 3x+1 into equation (2):

2x - y = 8

2x - (3x + 1) = 8

-x -1 = 8

-x = 9

Multiply by (-1)

x = -9

Substitute back x = -9 into equation (1)

y = 3x + 1

-42 is the constant for all values of x. If the given the functions f(x) = 3x - 21 and g(x) = 3x+21

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

Given an arbitrary number x, lets calculate,

⇒ f(x) - g(x)

                   =  3x - 21 - (3x+21)

                   = 3x - 3x -21 -21

                   = 0 - 42

                   = -42

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Assessed value of a house = 60% of current market value

Property tax = 3.9% of the assessment value

Now the given market value of a house is $420,000

Assessed value of a house = 60% of $420,000

⇒ Assessed value of a house = 0.60 * $420,000

⇒ Assessed value of a house = $252,000

Thus, Property tax = 3.9% of $252,000

⇒ Property tax = 0.039 *$252,000
