The number of subscribers to an online magazine is increasing by 34% each year. the function represents the number of subscribers after t years. f(t) = 13,000(1.34)^t which statement is true? a. the expression (1.05)6t reveals the approximate rate of increase in the number of subscribers if measured six times a year. b. the expression (1.15)3t reveals the approximate rate of increase in the number of subscribers if measured three times a year. c. the expression (1.03)4t reveals the approximate rate of increase in the number of subscribers if measured four times a year. d. the expression (1.12)2t reveals the approximate rate of increase in the number of subscribers if measured two times a year.

A.  The expression   reveals the approximate rate of increase in the number of subscribers if measured six times a year.

Step-by-step explanation:

Here, The number of subscribers to an online magazine is increasing by 34% each year. The function represents the number of subscribers after t years.

where represents rate of increase in the number of subscriber.

If rate is measured six times a year

then the number of subscriber,

( approx)

Thus, when we measure increment in six times a year then the rate  rate of increase in the number of subscribers=

Therefore Option A is correct.

Note: Option B) is incorrect because rate of increase in the number of subscribers if measured three times a year = ( approx)

Option C) is incorrect because rate of increase in the number of subscribers if measured four times a year =   ( approx)

Option D) is incorrect because rate of increase in the number of subscribers if measured two times a year =   ( approx)
