Question

Can you solve 13 and 14 I’ll make you brilliant ASAP

Answer 1

• 13. t = 5
• 14. 135 min

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
