Answer:
3:36 PM
Step-by-step explanation:
Let fraction (y) of the people that heard the rumor , the differential equation that is satisfied by the by y is,
Solving the differential equation,
The total number of inhabitants of the town = 2000
The number of people that heard the rumor = 160
At 8 AM, let t = 0,
= 0.08
By noon, half of the town as heard the rumor.
Then,
Therefore,
k ≈ 0.06106
Calculating time, t when y(t) = 90%
⇒ y(t) = 0.9
t = 7.59 hours
⇒ 7 hours 36 minutes
From 8 A.M. plus 7 hours 36 minutes = 3:36 PM
At 3:36 PM will 90% of the population have heard the rumor
I got...
2a(to the fourth power) plus 12a(to the second)b(to the second). I also checked this online.
The greatest common factor for 24 and 60 is 12. To solve just make it a fraction.
24/60 then divide until there's nothing in common anymore. Then you add the numbers you divide. So if you divided by three four times or vise versa then you'd get 12.
Hope that helped. C=
