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>
V=hπr^2
V=(2k+1)π(3k)^2
V=π(2k+1)(9k^2)
V=π(18k^3+9k^2)
V=18πk^3+9πk^2
I’m almost positive it’s the second one but check to be sure
Answer:
B as we start with X intercept =0
Step-by-step explanation:
x= 10 x 6 = 60
(v= 1/6x = 6x x 10y) x= 60v
y=10
When x=0 then y = 0 when x= 10 we have 10 minutes each count
So the graph will go up by 10 to 60 on the x axis.
value of nickle=6 and units of 10 nickles have value of 60
But this is a measure of time using nickles for x.
and measure of quarters can then show a pattern of zero each time. y=mc+x = 0 when y=0 = y=1x0+0 when x =6 and y=0
