Answer:
See Explanation
Step-by-step explanation:
Now;
From;
P=Poe^kt
Where;
P = population at time=t
Po = population initially present
k = growth rate
t = time taken
a) The function is;
P= 112,000e^0.04t
b) In the year 2004, the population will be
P= 112,000e^0.04(6)
P= 142380
c) 200,000 =112,000 e^0.04t
200,000/112,000 = e^0.04t
1.786 = e^0.04t
ln 1.786 = ln e^0.04t
ln 1.786= 0.04t
t = ln 1.786/0.04
t = 14.5 years

Answer:
Jennifer
4/15 mph
Step-by-step explanation:
First, we find the two speeds in miles per hour.
Victoria:
1 1/5 mile per 1/2 hour = (1 1/5 mile)/(1/2 hour) = 2 2/5 mph = 2.4 mph
Jennifer:
2/3 mile per 1/4 hour = (2/3 mile)/(1/4 hour) = 8/3 mph = 2 2/3 mph
2 2/3 mph > 2 2/5 mph, so Jennifer's speed is greater.
The difference in speeds in mph is:
2 2/3 - 2 2/5 = 2 10/15 - 2 6/15 = 4/15
