Answer:
the expression above is
y = Subscribers after time t = S
a = Initial Subscribers =20,000
r = Growth rate = 0.08 = 8%
t = time in years = y
Explanation:
A cable company uses the formula S = 20,000 (1 + 0.08)^y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.008) ^y?
The above question represents Exponential growth
Exponential growth formula =
y = a( 1 + r) ^t
Where:
y = Population after time t
a = Initial Population
r = Growth rate
t = time in years
S = 20,000 (1 + 0.08)^y
Hence, the expression above is
y = Subscribers after time t = S
a = Initial Subscribers =20,000
r = Growth rate = 0.08 = 8%
t = time in years = y
