Answer:

Step-by-step explanation:

The initial amount and rate of change given a table for a linear function are $65 and $86, respectively

The table of linear function represents the given parameter

On the table, we have the following points

(x, y) = (6, 476) and (10, 736)

The rate of change is calculated as

Rate = (y2 - y1)/(x2 - x1)

So, we have

Rate = (736 - 476)/(10 - 6)

Evaluate

Rate = 65

This means that the rate of change is $65

The initial amount is calculated as

y = m(x - x1) + y1

Where

m = 65

So, we have

y = 65(x - x1) + y1

Using one of the points, we have

y = 65(x - 6) + 476

Set x = 0

So, we have

y = 65(0 - 6) + 476

Evaluate

y = 86

Hence, the initial amount and rate of change given a table for a linear function are $65 and $86, respectively

Answer:

-7/18

Step-by-step explanation:

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

( -1/2 × 9/9) + (1/9 × 2/2) = ?

Complete the multiplication and the equation becomes:

-9/18 + 2/18 = ?

Then:

-9+2/18 = -7/18

Therefore:

-1/2 + 1/9 = -7/18

Answer:

x = 10

Step-by-step explanation:

What is the 10% of number in which the 14% is 160

Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it. A% is a number that has neither dimensions nor a defined unit of measurement.

being that,

14% × x = 160

14/100 × x = 160

x = 160 × 100/14

x = 1142.86

The current value is 1142.86.

10% of the total number must be located.

to say,

10% x 1142.86 = 10 / 100 x 1142.86

= 114.286

Consequently, 114.286 is the value of the 10% of the number.

The sum of the numbers as a product of their GCF is 5 x ( 5 + 7 ).

Given,

25 + 35.

We need to find its GCF and another sum.

It is the greatest factor common to both 25 and 35.

Example: 8 and 24

- 4 x 2 = 8

- 4 x 6 = 24

4 is the GCF.

Find the GCF of 25 and 35.

5 x 5 = 25

5 x 7 = 35

5 is the GCF of 25 and 35.

Now,

25 + 35 = 60

5 x ( 5 + 7 ) = 5 x 12 = 60

The sum of the numbers as a product of their GCF is 5 x ( 5 + 7 )

Thus,

Given the number of cities in a region is represented by the function:

C(x) = 2.9(1.05)ˣ

The approximate number of people per city is represented by the function P(x) = (1.05)³ˣ⁺⁵

we are asked to determine T(x), the approximate population in the region = ?

combine C(x) and P(x)

therefore, T(x) = C(x)P(x)

T(x) = 2.9(1.05)ˣ(1.05)³ˣ⁺⁵

During multiplication, when bases are same then powers are added.

T(x) = 2.9(1.05)³ˣ⁺ˣ⁺⁵

T(x) = 2.9(1.05)⁴ˣ⁺⁵

According to the given statement;

If ​P(A)=0.9​, ​P(B)​=0.1, and A and B are​ independent, ​ P(A and​ B)=0.09

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other possible outcomes and the coin is fair, the odds of both the outcomes, "heads" and "tails," are equally likely to occur. As a result, the probability of either outcome is half.

According to the given value;

P(A) = 0.9

P(B) = 0.1

A and B independent;

We know that independent

P(A∩B) = P(A) · P(B)

             = (0.9)*(0.1)

             =0.09

P(A∩B) =0.09

Answer-  A) 59,600 ; B) 4.12% per year.

Explanation

84,200 minus 24,600 is 59,600. This means the originally cost put into the account was 59,600.

Next we have to divide the amount of interest earn into the number of years that the amount was accumulated. 24,600 divided by 10 is 2460. This means that each year 2,460 were earned in interest. 59,600 divided into 2,460 is 0.0412751678. This rounds to .0412 If we move our decimal to a percentage this leaves us with 4.12% This means that annual interest on the investment is 4.12%

The correct option is option C that is the due amount which Tina needs to pay at the end of fourth month is $ 614.4.

What is algebra ?

Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.

It is given that Tina needs to purchase a refrigerator as replacement for $1100.

The monthly periodic rate if balance is not paid by the second month = 1.2 %

The amount she paid by the second month = $500

The due amount is :

= 1100 - 500

= $600

This amount she decided to pay by end of fourth month or after two more months.

Let's assume the amount she had to pay now at the end of fourth month is x then it given by :

= 600 + ( 600 × [tex]\frac{1.2}{100}[/tex] × 2)

= 600 + ( 12 × 1.2 )

= 600 + 14.4

The equation of a line which is perpendicular to [y = (4x - 11)] and passes through the point (-2, 1) will be [(4y + x) = 2].

As per the question statement, a line is perpendicular to [y = (4x - 11)] and passes through the point (-2, 1).

We are required to determine the equation of the above mentioned line.

Now, we know that, the standard equation of a line goes as [y = (mx + c)] where, "m" is the slope of the line while "c" is the y-intercept.

Comparing [y = (4x - 11)] to the standard form, we can identify that (m = 4), i.e., slope of the given line is 4.

Since the products of the slopes of two perpendicular lines is (-1), and considering the slope of our required line to be "m₁", we can say that,

[tex]4*m_{1}=(-1)\\ or,m_{1}=\frac{-1}{4}[/tex]...[since our required line is perpendicular to [y = (4x - 11)]

                        and slope of [y = (4x - 11)] is 4]

That is, slope of our required line is [tex](\frac{-1}{4})[/tex].

Another concept we need to know about forming the equation of a line is that, the equation of a line can be written as  [tex][(y-y_{1})=m(x-x_{1})][/tex], if the line passes through the point (x₁, y₁).

Here, our concerned line passes through the point (-2, 1) and has a slope of [m =  [tex](\frac{-1}{4})[/tex]].

Therefore, equation of our concerned line can be written as

[tex](y-1)=(\frac{-1}{4})[x-(-2)]\\or,(y-1)=(\frac{-1}{4})(x+2)\\or,(y-1)=(\frac{-x}{4})+(\frac{-1}{4}*2)\\ or,(y-1)=(\frac{-x}{4})+(\frac{-1*2}{4})\\or,(y-1)=(\frac{-x}{4})+(\frac{-1}{2})\\or,y=(\frac{-x}{4})+1+(\frac{-1}{2})\\or,y=(\frac{-x}{4})+(1-\frac{1}{2})\\or, y=(\frac{-x}{4})+\frac{1}{2}\\or,4y=(-x)+2\\or,4y+x=2[/tex]

Step-by-step explanation:

The average rate of change is 1.625.

The average rate of change in height for chuck can be found as follows:

The average rate of change is a measure of how much the function changed per unit, on average, over that interval.

Therefore,

average rate of change = change in y / change in x

Therefore,

(10, 51)(18, 64)

average rate of change = y₂ - y₁ / x₂ - x₁

x₁ = 10

x₂ = 18

y₁ = 51

y₂ = 64

Therefore,

average rate of change = 64 - 51 / 18 - 10

average rate of change = 13 / 8

average rate of change = 1.625

In this problem we know the location of the midpoint and the line segment ratio. There are two posibilities according to the definition of line segment ratio:

AX / BX = 2 / 3   (1)

BX / AX = 2 / 3   (2)

And now we solve for each case:

Case 1

X(x, y) = A(x, y) + (2 / 5) · [B(x, y) - A(x, y)]

X(x, y) = (3 / 5) · A(x, y) + (2 / 5) · B(x, y)

(4.8, 0.8) = (3 / 5) · A(x, y) + (2 / 5) · B(x, y)

(4.8, 0.8) = 0.6 · A(x, y) + 0.4 · B(x, y)

(4.8, 0.8) - 0.6 · A(x, y) = 0.4 · B(x, y)

(12, 2) - 1.5 · A(x, y) = B(x, y)

B(x, y) = (12, 2) - 1.5 · A(x, y)

Now we proceed to check each choice:

Case 2

X(x, y) = B(x, y) + (2 / 5) · [A(x, y) - B(x, y)]

X(x, y) = (2 / 5) · A(x, y) + (3 / 5) · B(x, y)

(4.8, 0.8) = (2 / 5) · A(x, y) + (3 / 5) · B(x, y)

(4.8, 0.8) = 0.4 · A(x, y) + 0.6 · B(x, y)

(12, 2) - 0.667 · A(x, y) = B(x, y)

B(x, y) = (12, 2) - 0.667 · A(x, y)

Now we proceed to check each choice:
