Can be rounded to 139 or 139.4 hope this helps
Population are often modelled by exponential functions
The population will reach 1000000 people after 26.5 years
The population function is given as:
When the population reaches 1000000 people, we have:
P(x) = 1000000
So, the equation becomes
Divide both sides by 692600
Take logarithm of both sides
Apply logarithm to both sides
Make x the subject
Solve the logarithms of 1.444 and 1.014
Divide
The value of x, is the number of years the population reaches 1000000 people.
Hence, the population will reach 1000000 people after 26.5 years

Answer:
3.1
Step-by-step explanation:
Complete question :
The Daily Info charges a fee $650 of plus $80 per week to run an ad. The People's Paper charges $145 per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper
Answer:
650 + 80w < 145w
Step-by-step explanation:
Given that :
Number of weeks ad will run = w
Daily Info total cost :
650 + 80w
The People's Paper total cost:
145w
Number of weeks ad should run For cost at daily info to be less expensive than peoples choice';
Daily Info total cost < people's choice
650 + 80w < 145w
650 < 145w - 80w
650 < 65w
650/65 < 65w / 65
10 < w
w > 10
