Step-by-step explanation:
The circumference of a circle can be found using the following formula.

The diameter is 2.5 centimeters. Therefore, we can substitute 2.5 cm in for d.

Now, find the circumference.

Let
and 
The slope of the line is given by:



The equation of the line is given by:






Therefore, the function equation represented by the graph is: 
Answer:
option c
Step-by-step explanation:
option c is right..
A x = 0
using the law of exponents
= 1
for (6² )^ x = 1 then x = 0
B note that
= 1 ⇒ x = 1
2 → 2^8 × 3^(-5) × 1^(-2) × 3^(-8) × 2^(-12) × 2^(28)
= 2^(8 -12 + 28) × 1 × 3^(- 5 - 8)
= 2^24 × 3^(- 13) = 2^(24)/3^(13) = 10.523 ( 3 dec. places)
