You can see how this works by thinking through what's going on.
In the first year the population declines by 3%. So the population at the end of the first year is the starting population (1200) minus the decline: 1200 minus 3% of 1200. 3% of 1200 is the same as .03 * 1200. So the population at the end of the first year is 1200 - .03 * 1200. That can be written as 1200 * (1 - .03), or 1200 * 0.97
What about the second year? The population starts at 1200 * 0.97. It declines by 3% again. But 3% of what??? The decline is based on the population at the beginning of the year, NOT based no the original population. So the decline in the second year is 0.03 * (1200 * 0.97). And just as in the first year, the population at the end of the second year is the population at the beginning of the second year minus the decline in the second year. So that's 1200 * 0.97 - 0.03 * (1200 * 0.97), which is equal to 1200 * 0.97 (1 - 0.03) = 1200 * 0.97 * 0.97 = 1200 * 0.972.
So there's a pattern. If you worked out the third year, you'd see that the population ends up as 1200 * 0.973, and it would keep going like that.
So the population after x years is 1200 * 0.97x
Answer:
range of the given function in Interval notation is [-1, 3]
Step-by-step explanation:
i) given function is y = 1 + 2sin(x - 11)
ii) maximum of sin function is 1
iii) therefore maximum of given function 
= 1 + (2
1) = 3
iv) minimum of sin function is -1
v) therefore maximum of given function = 1 + (2 -1) = -1
vi) therefore the range of the given function in Interval notation is [-1,3]
EZ: two rectangles and one triangle :P
15*4 + 10*3 + 3*4/2 = 60+30+6 = 96 ... nice number
Answer:
236x
Step-by-step explanation:
Product means multiply.
In math, we always write the number first, which is called the coefficient.
So 236x.
