Answer:
The loan will cost you 2000 dollars more.
Step-by-step explanation:
If you pay 200 per month for 60 months, then you are paying 200(60) after the 60 months.
200(60)=12000.
So the loan will cost you 12000.
The difference between paying 12000 and 10000 is 2000.
The loan will cost you 2000 dollars more.
The answer is A, pi. (Sorry I don’t have three pi symbol on my phone.)
Answer:
9,942 bacteria were there at 10 hours.
Step-by-step explanation:
Equation for population decay:
The equation for population decay, after t hours, is given by:
In which P(0) is the initial population and r is the decay rate, as a decimal.
Researchers recorded that a certain bacteria population declined from 200,000 to 900 in 18 hours.
This means that and that when . So we use this to find r.
So
At this rate of decay, how many bacteria was there at 10 hours?
This is P(10). So
Rounding to the nearest whole number:
9,942 bacteria were there at 10 hours.
A.

Megan's solution isn't correct.
The first mistake: she subtracted 5x from the right-hand side of the equation, but added 5x to the left-hand side.
The second mistake: she divided the right-hand side of the equation by 11, but didn't divide the left-hand side.
The correct solution:
