The slope is 3 y-intercept is 7 and the equation would be y=3x+7
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>
ANSWER
x = -1
x= 1
x = 3
Step-by-step explanation:
the answer is this
x=(5*21)/7=15 taken spaces
total =empty spaces+taken spaces= 21+15=
36
