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:
25
Step-by-step explanation:
The longest side is 12.
The two other sides of the triangle=
=(9+36)square rooted=45 square rooted is about 6.7.
6.7*2=13.4
13.4+12=25.4
25.4 rounded to the nearest unit is 25.
50 x
-- = ---
100 75
We need to find the value of x.
Cross multiply:-
100x = 75 * 50
Divide both sides by 100
x = (75* 50) / 100
= 75 / 2
= 37.5 (answer)
