Answer:
Step-by-step explanation:
The population P of a certain city can be modeled by
P=19000e0.0215t
where T represent the number of years since 2000.
When t=1 the year is 2001
when t =2 the year is 2002. This means that
When t=0 the year is 2000
To determine the year when the population will be 40,000 , we will substitute P = 40,000 and solve for t. It becomes
40000 = 19000e^0.0215t
40000 / 19000 = e^0.0215t
2.105 = e^0.0215t
Take ln of both sides
0.7443 = 0.0215t
t = 0.7443/0.0215
t = 34.62
Approximately 35 years
So the year will be 2035
Answer:
A.) The temperature fell in the last minute, but less than it fell in the minute before.
Step-by-step explanation:
Given that for three minutes the temperature of a feverish person has had negative first derivative and positive second derivative.
i.e. it temperature is represented by T, temperature is variable with
first derivative T' <0 and second derivative T">0
i.e. rate of change of temperature is negative or temperature is falling down in 3 minutes.
But the rate of rate of change of temperature was positive i.e. the rate of change of temperature is increasing as time increases.
So correct option would be option A
A.) The temperature fell in the last minute, but less than it fell in the minute before.
If you have no calculator, pretend like the decimals aren’t there then add them back depending on how many places you have after the decimal. for example: 2.5 times 2.5, if you pretend there are no decimals, you get 625, then you have to add the decimals back. since you have 1 digit after each decimal in each number, you add 1+1=2 to get the number of places you have to add back. so you get 6.25
