Domain is all real numbers. Range is

Step-by-step explanation:

The function  is a transformation of the parent function  by moving the function up by 3 units.

So, the graph of the function is shown below.

From the graph, it is clear that the  values has no limitation and hence can take any real values. Domain is the set of all possible  values.

So, domain is the set of all real numbers.

Range is the set of all possible values for  for the given domain.

From the graph, the minimum value of  is at the point (. So, the minimum value of y is 3. The  value then goes on increasing towards infinity.

Therefore, range is a real number greater than or equal to 3.

So, range is  or  

an = a1 + (n - 1)d

Substituting the values

an = 2 + (n - 1)8

We have to find the 25th term n = 25

a25 = 2 + (25 - 1)8

a25 = 2 + (24)8

a25 = 2 + 192

a25 = 194

======================================================

Explanation:

The gap between adjacent terms is 8.

The long way to get the answer would be to keep adding 8 to each term to generate the next one. You'd need to do this 20 times. There are 5 terms here already, so you need 25-5 = 20 more operations of "add 8".

I don't recommend this option. I recommend the shortcut mentioned in the next section.

--------

The shortcut would be to find the nth term of the arithmetic sequence

[tex]a_1 = 2 = \text{ first term}\\\\d = 8 = \text{ common difference}\\\\a_n = \text{ nth term}\\\\a_n = a_1 + d(n-1)\\\\a_n = 2 + 8(n-1)\\\\[/tex]

As a check, plug n = 1 into that formula to get [tex]a_1 = 2[/tex]. Plug n = 2 to get [tex]a_2 = 10[/tex] and so on. I'll leave this check portion for the student to do.

--------

The last step is to plug n = 25 into that formula to determine the 25th term.

[tex]a_n = 2 + 8(n-1)\\\\a_{25} = 2 + 8(25-1)\\\\a_{25} = 2 + 8(24)\\\\a_{25} = 2 + 192\\\\a_{25} = 194\\\\[/tex]

-------

Extra section (optional):

We can use a spreadsheet to generate the 25 terms. This is to help check the answer.

Answer:

24 years

Step-by-step explanation:

If interest is not compounded, it is called simple interest.

Simple interest is calculated as a percentage of the principal amount and is applied only to the principal.

The formula for simple interest is:

[tex]\boxed{\sf I = Prt}[/tex]

where:

The given values are:

Substitute the given values into the formula and solve for t:

[tex]\implies \sf 100=70 \cdot 0.06 \cdot t[/tex]

[tex]\implies \sf 100=4.2 t[/tex]

[tex]\implies \sf 4.2 t=100[/tex]

[tex]\implies \sf \dfrac{4.2 t}{4.2}=\dfrac{100}{4.2}[/tex]

[tex]\implies \sf t=23.8095238...\;years[/tex]

We need to round up to the next year. Therefore, it will take 24 years for John to make at least $100 in interest.

Answer:

approx. 24 years

Step-by-step explanation:

The formula to find the simple interest is:

[tex]\sf I= \frac{prt}{100}[/tex]

Here,

I ⇒ Interest ⇒ $ 100

p ⇒ principle ⇒ $ 70

r ⇒ rate ⇒ 6

t ⇒ time ( years )

Let us find the time taken using the formula.

[tex]\sf I= \frac{prt}{100}\\\\100=\frac{70*6*t}{100} \\\\100*100=420t\\\\10000=420t\\\\23.8\: years=t\\\\approx. \:24 \:years=t[/tex]

Answer:

Step 1: Write down the decimal as a fraction with the decimal number as the numerator and 1 as the denominator.

Step 2: Multiply both the numerator and denominator by 10^n, where n is the number of digits after the decimal point.

Step 3: Simplify the resulting fraction.

Using these steps, we can convert the given decimal numbers to fractions:

0.65

Step 1: 0.65 = 65/100

Step 2: Multiply numerator and denominator by 10 to get rid of the decimal point: 65/100 = 650/1000

Step 3: Simplify by dividing numerator and denominator by their greatest common factor of 50: 650/1000 = 13/20

Therefore, 0.65 expressed as a fraction in simplest form is 13/20.

2.¯5

To handle repeating decimal numbers, we can use the following method:

Step 1: Let x be the repeating decimal number.

Step 2: Multiply both sides of x by 10^n, where n is the number of digits in the repeating part of the decimal number.

Step 3: Subtract the original number from the number obtained in step 2 to eliminate the repeating part.

Step 4: Solve for x by dividing both sides of the equation obtained in step 3 by an appropriate factor.

Step 1: Let x = 2.¯5

Step 2: Multiply both sides by 10: 10x = 25.¯5

Step 3: Subtract the original equation from step 1: 10x - x = 25.¯5 - 2.¯5

Simplifying: 9x = 23

Step 4: Solve for x by dividing both sides by 9: x = 23/9

Therefore, 2.¯5 expressed as a fraction in simplest form is 23/9.

1.0¯24

Step 1: Let x = 1.0¯24

Step 2: Multiply both sides by 10^2 to eliminate the repeating part: 100x = 124.¯24

Step 3: Subtract the original equation from step 1: 100x - x = 124.¯24 - 1.0¯24

Simplifying: 99x = 123

Step 4: Solve for x by dividing both sides by 99: x = 123/99

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor of 3: 123/99 = 41/33.

Therefore, 1.0¯24 expressed as a fraction in simplest form is 41/33.

Step-by-step explanation:

0.65 expressed as a fraction in simplest form is 13/20.

2.5 expressed as a fraction in simplest form is 5/2.

1.024 expressed as a fraction in simplest form is 256/250.

0.65 expressed as a fraction in simplest form:

Write the decimal as a fraction by placing it over 1. In this case, 0.65 becomes 0.65/1.

Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.

In this case, multiplying by 100 will do the trick, so we get (0.65 × 100)/(1 × 100) = 65/100.

Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).

The GCD of 65 and 100 is 5, so dividing both by 5 yields 13/20.

2.5 expressed as a fraction in simplest form:

Write the decimal as a fraction by placing it over 1. In this case, 2.5 becomes 2.5/1.

Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.

In this case, multiplying by 10 will do the trick, so we get (2.5 × 10)/(1 × 10) = 25/10.

Lastly, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).

The GCD of 25 and 10 is 5, so dividing both by 5 yields 5/2.

1.024 expressed as a fraction in simplest form:

Write the decimal as a fraction by placing it over 1. In this case, 1.024 becomes 1.024/1.

Remove the decimal by multiplying both the numerator and the denominator by a power of 10 that will eliminate the decimal.

In this case, multiplying by 1000 will do the trick, so we get (1.024 × 1000)/(1 × 1000) = 1024/1000.

Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (GCD).

The GCD of 1024 and 1000 is 8, so dividing both by 8 yields 128/125.

Answer:

The equation that represents a linear function is:

y = 5x - 6

Step-by-step explanation:

This equation has a constant rate of change, which means that for every unit increase in x, there is a consistent and constant increase or decrease in y. This is a characteristic of linear functions, where the relationship between x and y is a straight line.

y = 5x - 6 is represents a linear function.

A linear function is a type of function in which the highest power of x is one. The graph of a linear function has only one solution, and intercept x - axis at only one point and intercepts y - axis at only one point as well.

Generally, the equation of a linear function is given as;

y = mx + c

Answer:

1.5 miles less

Step-by-step explanation:

Step 1:  Find equation for Alexanda

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

If we allow (8, 345.6) to be our x1 and y1 and (12, 518.4) to be our x2 and y2, our slope is

[tex]m=\frac{(518.4-345.6)}{(12-8)}\\ m=\frac{172.8}{4}\\ m=43.2[/tex]

[tex]345.6=43.2(8)+b\\345.6=346.6+b\\0=b[/tex]

Thus, the equation for Alexandra is y = 43.2x

Step 2: Plug in 1 for x for both Fabian and Alexandra's equations and subtract

Since x is is gallons, we plug in 1 for x for each equation and subtract Fabian's miles from Alexandra's miles to find how many miles less can Fabian drive one 1 gallon of gas than Alexandra:

Fabian:  y = 41.7(1) = 41.7

Alexandra:  y = 43.2(1) = 43.2

Difference of Alexandra and Fabian's miles:  43.2 - 41.7 = 1.5

Step-by-step explanation:

The 5 represents the number by itself so it would be

10x10x10x10x10=100,000

7.9x100,000=790,000

Step-by-step explanation:

if you multiply something by 10 = 10¹, you move the decimal point 1 position to the right (and fill up with a 0, if necessary).

if you multiply something by 100 = 10², you move the decimal point 2 positions to the right (and fill up with 0s as needed).

if you multiply something by 1000 = 10³, you move the decimal point 3 positions to the right (and fill up with 0s as needed).

...

you see the pattern ?

so, when multiplying by 10⁵ (100,000) we shift the decimal point 5 pairings to the right and fill up with 0s as needed.

therefore,
