Answer:(c)

Step-by-step explanation:

Given

the radius of circle=10 units

The center is 5 units below the origin i.e. (0,-5) is the center

The general equation of a circle is

(x-a)^2+(y-b)^2=r^2\quad [\text{Where, (a,b) is the center of the circle and r is radius}]

Putting values

(x-0)^2+(y-(-5))^2=10^2\\(x)^2+(y+5)^2=100

Second last option is correct

Answer:

x² + (y + 5)² = 100

Step-by-step explanation:

If the center of the circle is 5 units below the origin, its x coordinate is 0 and its y-coordinate is -5. So, the center of the circle is at (0, -5).

Using the equation of a circle with center (h, k)

(x - h)² + (y - k)² = r² where r = radius of the circle.

Given that r = 10 units, and substituting the values of the other variables into the equation, we have

(x - h)² + (y - k)² = r²

(x - 0)² + (y - (-5))² = 10²

x² + (y + 5)² = 100

which is the equation of the circle.

Complete the recursive formula of the geometric sequence 27,,-9,3-1,...<br> b(1)=<br> b(n)=b(n−1)⋅
natta225 [31]

Answer:

The recursive formula of the geometric sequence is:

  • aₙ = aₙ₋₁ (r)

Step-by-step explanation:

A recursive formula is a formula using which every next term is based on the previous term.

Each next term of a geometric sequence can be determined when we multiply the previous term with a constant. That constant number is called a 'common ratio' which is denoted by 'r'.

Given the sequence

27, -9, 3, -1,...

Let us find the common ratio 'r' of all the adjacent terms

r = -9/27 = -1/3,   r = 3/-9 = -1/3, r = -1/3

Thus, the common ratio is: r= -1/3

The recursive formula for the geometric sequence is:

aₙ = aₙ₋₁ (r)

Here,

aₙ represents the general term

aₙ₋₁ represents the previous term

'r' represents the common ratio

as

a₁ = 27

Substituting our values, we have

aₙ=aₙ₋₁(r)

Putting n=2 to get the second value

a₂=a₂₋₁(-1/3)

   = a₁ (-1/3)

   = 27 (-1/3)

   = -9

Thus, the next term of a geometric sequence can be determined when we multiply the previous term with a constant.

Therefore, the recursive formula of the geometric sequence is:

  • aₙ = aₙ₋₁ (r)
