It will take 6 weeks for the number of infected people to reach 1200
<h3>How to determine the number of weeks?</h3>
The function is given as:
y equals 15 times 2 to the power of t
Rewrite the function properly as follows
y = 15 * 2^t
When the population is 1200, the equation becomes
15 * 2^t = 1200
Divide both sides by 15
2^t = 80
Take the logarithm of both sides
t * log(2) = log(80)
Divide both sides by log(2)
t = 6.3
Approximate
t = 6
Hence, it will take 6 weeks for the number of infected people to reach 1200

16 + b^2 = 36
b^2 = 20
b = 4.472
Well there are 60 minutes in an hour so 60-20=40 so the time
is 11:40 A.M.
