Since there could be no more than 12 the multiples of 1/3 untill a denominator of 12 are 2/6 3/9 and 4/12
2 3/4 = 11/4 <=== written as an improper fraction
General equation of a circle with centre (h, k) is given by:

Now, the origin is the centre and radius is 20, so substituting these points in yields:

Answer:
36-2n<1/3n+15
Step-by-step explanation:
There are multiple solutions. One solution is 30. Because 30 times 2 is 60 and 36-60 is less than 1/3 of 30 (10) plus 15.
An exponential model can be described by the function

where: a is the initial population or the starting number, b is the base and x is the number of periods elapsed.
When the base of an exponential model is greater than 1 it is called a growth factor, but when it is less than 1 it is called a decay factor.
Given the exponential model

n is the final output of the exponential model, 20.5 is the starting number, 0.6394 is the base and t is the number of periods/time elapsed.
Here, the base is 0.6394 which is less than 1, hence a decay factor.
Therefore, <span>the
base, b, of the exponential model is 0.6394; It is a
decay factor.</span>
