(Second Question in photo) BTW the question is:
Using the diagram at the right, which of the following represents the ratio of
the circle's circumference to the square's perimeter?

Reminder (because this isn't geometry yet): C = 21 * (radius)

(a) r/pi
(b) 4/r
(c) 4/pi
(d) pi/4
(e) r/4

Option (D).

Step-by-step explanation:

Perimeter of a square is given by the expression,

P = 4(Side)

Since length of a side of the given square = 2r

P = 4(2r)

  = 8r

Circumference of a circle is represented by,

C = 2πr

Ratio of the Circle' circumference and perimeter of the square =

   =

Therefore, Option (D) represents the ratio of circumference of the circle and perimeter of the square.

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
