Answer:

C =28.26m

Step-by-step explanation:

We are walking around a circle, which means we are finding the perimeter.  The perimeter of a circle is called the circumference.

We find the circumference by

C = pi *d  where d is the diameter

C = 3.14 * 9

C =28.26m

sammy [17]

The value of function on x=1 is 0.5

Step-by-step explanation:

In order to find the value of a function on given input, the input is put at the place of variable in the function.

Given function is:

f(x) = (\frac{1}{2})^x

We have to find the value of function on x = 1

Putting x = 1 in function

f(1) = (\frac{1}{2})^1\\= \frac{1}{2}\\= 0.5

Hence,

The value of function on x=1 is 0.5
