Answer:

a_{n} = 7n - 4

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 3 and d = a₂ - a₁ = 10 - 3 = 7 , thus

a_{n} = 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4

Circle L is shown. Line segments K L and M L are radii. The length of K L is 12. Angle M L K is 60 degrees. Sector M L K with a
kozerog [31]

Answer:

Area of Un-shaded Sector is 376.99

Step-by-step explanation:

From the information given, we can say:

Radius of Circle = 12 (Since KL is radius and KL = 12)

The sector of shaded area covers 60 degrees

Total circle is 360, so unshaded sector is:

360 - 60 = 300 degrees

So, to find Non-Shaded Sector Area, we use sector area formula:

A=\frac{\theta}{360}*\pi r^2

Where

\theta  is the angle of the sector (in our case, it is 300)

So we substitute and find the answer:

A=\frac{300}{360}*\pi (12)^2\\A=\frac{5}{6}*\pi*144\\A=120\pi\\A=376.99

The area is 376.99

Julia has read her favorite book 6 times,This is 3 times more than her Kami.How many times has Kami read the book?
motikmotik

Answer:    The answer is:  " 2 " .  

_______________________________________________

        → Kami has read the book "<u>  2 (two)  </u>" times.

_______________________________________________

Step-by-step explanation:

_______________________________________________

Let "J" represent the number of times julia has read the book.

Let "K" represent the number of times Kami has read the book.

J = 6 ;  

J = 3K ;  

Solve for "K" ;

J = 6 = 3K ;

→ 6 = 3K ;

 ↔  3K = 6 ;

Divide each side of the equation by "3" ;

to isolate "K"  on one side of the equation; & to solve for "K" :

→  3K / 3  =  6 / 3 ;

to get:

  K = 2 .

_______________________________________________

 The answer is:  " 2 " .

        → Kami has read the book "<u>  2 (two)  </u>" times.

_______________________________________________
