Assuming that the growth the function will be of the form
f(n) = P*R^n
where
P = Initial population
R = Growth rate per period
n = number of periods
In this problem, the only period or interval I see are days. So we'll use n to represent the number of days since the start. The initial population is 1000, and the ratio would be 1600/1000 = 1.6. So the formula becomes
f(n) = 1000*1.6^n
So let's evaluate that function using n=4.
f(n) = 1000*1.6^n
f(4) = 1000*1.6^4
f(4) = 1000*6.5536
f(4) = 6553.6
Since we can't have a fractional mosquito, round to the nearest integer, giving 6554.</span>
Justin’s fence will cost $72.
24ft = 24(12)
24(12) = 288 inches of fencing
288 (0.25) = $72
Answer:
Step-by-step explanation:
a) if the population at the beginning of the year 2000 was 7500 people,
The 1-year percent change in the city's population would be
3.6/100 × 7500 = 270
b) The population after 1 year is
7500 - 270 = 7230
The percentage of the previous value of the population to its new value for each year is
7230/7500 × 100 = 96.4%
c) the 1-year growth factor for the population of the city would be
(1 - 0.036)^1 = 0.964
d) the function, g that determines the population of the city (in thousands of people) in terms of the number of years t since the beginning of 2000 would be
g = 7500(1 - 0.036)^t
g = 7500(0.964)^t
1500 x 12% = 180mL
To get this answer, you have to multiply the 1500mL by 12% (0.12) and get 180. This means that 12% of your 1500mL solution will be 180mL of hydrochloric acid.
