$250: $8.75= 28.5. and you round that up to 29. cause 28 times 8.75 is $245. and that's below the amount that James needs
Answer:
Expected population in 2015: 19,152.58 or 19,000 people
Step-by-step explanation:
Given the decreasing rate of 2.5% per year, and a population of 28,000 in the year 2000:
We can solve for the rate of decrease by using the formula:
![A = a(1 - r )^{t}](https://tex.z-dn.net/?f=A%20%3D%20a%281%20-%20r%20%29%5E%7Bt%7D)
where:
A = population by year 2015
a = initial population (in year 2000) = 28,000
r = rate of change (decrease by 2.5% annually or 0.025)
t = time (in number of years) = 15
Plug in these given values into the formula:
![A = a(1 - r )^{t}](https://tex.z-dn.net/?f=A%20%3D%20a%281%20-%20r%20%29%5E%7Bt%7D)
![A = 28,000(1 - 0.025 )^{15}](https://tex.z-dn.net/?f=A%20%3D%2028%2C000%281%20-%200.025%20%29%5E%7B15%7D)
![A = 28,000(0.975)^{15}](https://tex.z-dn.net/?f=A%20%3D%2028%2C000%280.975%29%5E%7B15%7D)
A = 28,000(0.684)
A = 19,152.58 or about 19,000 people in 2015
answer is c
Step-by-step explanation:
its saying co
d so it means we have to minus 9 from minus 15 so it's 6
Answer:
3
Step-by-step explanation:
y = -9 when x = 3
When x = -4.5, the first definition of the function will be used since -4.5 is less than -3. In this region, y = -x implying that when x = -4.5, y= 4.5.
When x = 3, the last definition of the function will be used since 3 is greater than -2. In this region, y = -x^2 implying that when x = 3, y= -9.
