The function f(t) represents the cost to connect to the Internet at an online gaming store. It is a function of t, the time in minutes spent on the Internet.
$0 0<i< 30
FC = $5 30 <1 3 90
$ 10 1 > 90
Which statement is true about the Internet connection cost?
It costs $5 per hour to connect to the internet at the gaming store.
The first half hour is free, and then it costs $5 per minute to connect to the internet.
Any amount of time over an hour and a half would cost $10.
It costs $10 for each 90 minutes spent connected to the internet at the gaming store.

answer: i literally just answered this question but they want me to do it again

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
