Step-by-step explanation:

1). Let the length of a marathon race = x miles

   Marathon runner runs this race in the sequence formed as,

   [tex]\frac{x}{2},\frac{x}{4},\frac{x}{8}.........[/tex]

  Common ratio = [tex]\frac{\frac{x}{4}}{\frac{x}{2}}[/tex]

                           = [tex]\frac{x}{4}\times \frac{2}{x}[/tex]

                           = [tex]\frac{1}{2}[/tex]

  Therefore, it's a geometric sequence.

2). First movie rental cost = $2

  Followed by each additional movie rental cost = $1

  Therefore, rental of movies will be in the form of a linear equation,

  y = 2x + 1

  where x = number of movies

  And y = Rental of movies

  It's not a geometric sequence.

3). 10, 1, 0.1, 0.01.......

  Ratio in 2nd and 1st term = [tex]\frac{1}{10}=0.1[/tex]

  Ratio in 3rd and 2nd term = [tex]\frac{0.1}{1}=0.1[/tex]    

  Therefore, ratio in each term is common.

  Sequence formed will be a geometric sequence.

4). [tex]\sum_{k=1}^{7}4(0.2)^{k-1}[/tex]

   Expression represents a common ratio of 0.2,

  Therefore, expression given will represent a geometric sequence.

5). -4, 20, -100, 500, ...........

   Ratio of 2nd and 1st term = [tex]\frac{20}{-4}[/tex] = -5

   Ratio of 3rd and 2nd term = [tex]\frac{-100}{20}[/tex]

                                               = -5

   There is a common ratio = -5

   Therefore, it's a geometric sequence.

6). -1, 5, 11, 17.........

   Ratio of 2nd and 1st term = [tex]\frac{5}{-1}=-5[/tex]

   Ratio of 3rd and 2nd term = [tex]\frac{11}{5}=2.2[/tex]

   -5 ≠ 2.2

   Therefore, sequence is not a geometric sequence.

7). -500, 100, -20, 4........

   Ratio of 2nd and 1st term = [tex]\frac{100}{-500}=-\frac{1}{5}[/tex]

   Ratio of 3rd and 2nd term = [tex]\frac{-20}{100}=-\frac{1}{5}[/tex]

Answer:11

Step-by-step explanation:

18*1/3+5=11

Answer:

11

Step-by-step explanation:

To find the number that is 5 more than [tex]\frac{1}{3}[/tex] of 18, we can start by evaluating what [tex]\frac{1}{3}[/tex]  is:

[tex]\frac{1}{3}[/tex]  of 18

⇒ [tex]\frac{1}{3} \times 18[/tex]

To multiply a whole number by a fraction, we can convert the whole number into a fraction by giving it a denominator of 1:

⇒ [tex]\frac{1}{3} \times \frac{18}{1}[/tex]

⇒ [tex]\frac{18}{3}[/tex]   [This is the same as 18 ÷ 3]

⇒ [tex]\bf 6[/tex]

Now that we have the value of [tex]\frac{1}{3}[/tex] of 18, we can simply add to it to find the number that is 5 more than [tex]\frac{1}{3}[/tex] of 18:

[tex](\frac{1}{3} \times 18) + 5[/tex]

⇒ [tex]6 + 5[/tex]

⇒ [tex]\bf 11[/tex]

∴ The number we are looking for is 11.

10x - 4y = 5 (if it requires shorten)

Step-by-step explanation:

x + y/5 - 1 = y - x

<=> (5x + y - 1.5)/5 = 5(y - x)/5

<=> 5x + y - 5 = 5y - 5x

<=> 5x + 5x + y - 5y = 5

<=> 10x - 4y = 5

Answer:

Lol free points

Step-by-step explanation:

The car is at 60ft from you 5 seconds after it starts moving and 7.5 seconds after it starts moving.

The 48*t part means the number of feet that the car moves in t seconds

We know that the absolute value equation that models the distance is:

d(t) = |300 - 48*t|

Then what we need to solve is d(t) = 60, this is:

d(t) = 60 = |300 - 48*t|

That absolute value equation can be represented in two forms:

300 - 48*t = 60

300 - 48*t = -60

Solving these two we get the two times at which the car is at 60ft from you.

-48*t = 60 - 300

t = (60 - 300)/(-48)  = 5

t = (-60 - 300)/(-48) = 7.5

So the car is at 60ft from you 5 seconds after it starts moving and 7.5 seconds after it starts moving.

The 48*t part means the number of feet that the car moves in t seconds.

Answer:

11.5

Step-by-step explanation:

The function (5n² - 9) / (n + 3) is a natural number for n = 3 and n = 15.

A function is given which is (5n² - 9) / (2n + 6).

We have to find the value of natural number n for which the given function is also natural number.

What do you mean by natural numbers ?

Natural numbers are known as the counting numbers which starts from 1 and end at infinity and also includes the whole numbers excluding 0.

As per the question ;

(5n² - 9) / (2n + 6) is a natural number for the value of n which is also a natural number.

Let's assume ;

(5n² - 9) / (2n + 6) = k

or

(5n² - 9) / (n + 3) = 2k

So , we can say that (5n² - 9) / (n + 3) is an even number.

We know that ;

Dividend ÷ Divisor = Quotient

If we divide (5n² - 9) by (n + 3) we will get ;

Quotient = 5n - 15

and

Remainder = 36

We can write it as ;

(5n² - 9) ÷ (n + 3) = (5n - 15) + {36 / (n+ 3)}

Here ;

36 / (n+ 3) is a natural number and n is a natural number.

Assume ;

n = 1 , 3 , 6 , 9 , 15 , 33

Let's check ;

for n = 1 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (5 - 15) + {36 / (1+ 3)}

= -1

for n = 3 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (15 - 15) + {36 / (3+ 3)}

= 6

for n = 6 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (30 - 15) + {36 / (6+ 3)}

= 19

for n = 9 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (45 - 15) + {36 / (9+ 3)}

= 33

for n = 15 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (75 - 15) + {36 / (15+ 3)}

= 62

for n = 33 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (165 - 15) + {36 / (33+ 3)}

= 151

So , we found that only for values of n = 3 and n = 15 , the value of (5n - 15) + {36 / (n+ 3)} is also an even number.

Thus , the function (5n² - 9) / (n + 3) is a natural number for n = 3 and n = 15.

Step-by-step explanation:

Percentages

The x percent of a number N is calculated as:

[tex]\displaystyle P=\frac{x}{100}*N[/tex]

If the value of P is known, then:

[tex]\displaystyle N=\frac{100}{x}*P[/tex]

We know the store sold P=550 video games during the month of December and it corresponds to the x=12% of its yearly games sales (N).

Let's calculate N:

[tex]\displaystyle N=\frac{100}{12.5}*550[/tex]

N = 4,400

The store sold 4,400 video games all year.

The angle by which turns counterclockwise about point P to coincide with is 180 degree angle

What is 180 degree angle?

The angle which forms a straight line is called the 180-degree angle. A 180-degree angle is a straight angle and it is exactly half of a revolution. The two arms of the angle which are making 180-degree are just opposite to each other from the common vertex.

The points D, P and C forms a straight line.

So, if it turns clockwise about Point P, it would make an angle of 180 degree.

as the point D and C are of equal lengths and opposite to each other, the angle from P turning clockwise makes 180 degree angle.

Answer:

the answer is Y

Step-by-step explanation:

The greatest common factor (GCF) of two polynomial expressions is y.

The greatest common factor (GCF) of two polynomial expressions is the polynomial with the largest set of factors that is a factor of both polynomials.

To find the GCF of y2(y + 1) and y(y + 2), we can factor each polynomial:

y2(y + 1) = y(y)(y + 1)

y(y + 2) = y(y + 2)

The only factor that both polynomials have in common is y, so the GCF is y.

Here is the solution in more detail:

Factor each polynomial.

y2(y + 1) = y(y)(y + 1)

y(y + 2) = y(y + 2)

Find the factors that are common to both polynomials.

The only factor that both polynomials have in common is y.

The GCF is the polynomial with the largest set of factors that is a factor of both polynomials.

The GCF is y.
