Answer:

  • 13. t = 5
  • 14. 135 min

Step-by-step explanation:

13...........

f(t) = 2^(t/3)

f(t) = 32

  • 2^(t/3) = 32
  • 2^(t/3) = 2^5
  • t/3 = 5
  • t = 5*3
  • t = 15

14............

b = 100(2^t)

b= 51200

  • 100(2^t)= 51200
  • 2^t= 512
  • 2^t= 2^9
  • t = 9

9 periods of 15 min:

  • 9*15 = 135 min
