Answer:

<em>Answer: D</em>

Step-by-step explanation:

<u>Arithmetic Sequences </u>

The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

a_n=a_1+(n-1)r

Where

an = nth term

a1 = first term

r   = common difference

n  = number of the term

We are given the arithmetic sequence:

10, 12, 14, 16, ...

Where a1=10 and

r = 12 - 10 = 2

Thus the general term is:

a_n=10+(n-1)2

Operating:

a_n=10+2n-2

a_n=8+2n

Answer: D

Forty is no greater than the difference of a number and 2
GuDViN [60]
This can be written as:
40  \leq  n - 2

"No greater than" does not necessarily mean less than, but it just means it cannot go over. So equal to or less than.

"The difference of a number and 2" can be represented as "n - 2"

If you were to solve this inequality, you would end up getting:
42  \leq  n or n  \geq  42

Hope this helps! :)

Shkiper50 [21]

Answer:

❥

Diameter of a circle is 8 cm. Then find out the area and perimeter of the circle.

❥

Area of circle is 50.29(≈)cm² and perimeter of circle is 25.14(≈)cm.

❥

•Given :-

Diameter of the circle = 8 cm.

•To find :-

Area and perimeter of the circle.

• Solution :-

Let the radius of the circle be r cm.

Diameter = 8 cm.

We know,

★

So, Radius (r) = 8/2= 4 cm.

We know,

★

Area of circle= πr²

→Area of circle=

→Area of circle=

→Area of circle= 50.29(≈)cm²

____________________________

We know,

★

Perimeter of circle= 2πr

→ Perimeter of circle=

→Perimeter of circle=25.14(≈)cm
