Answer:
y=x-5 slope=1 y-intercept=-5
Step-by-step explanation:
We use P = i•e^rt for exponential population growth, where P = end population, i = initial population, r = rate, and t = time
P = 2•i = 2•15 = 30, so 30 = 15 [e^(r•1)],
or 30/15 = 2 = e^(r)
ln 2 = ln (e^r)
.693 = r•(ln e), ln e = 1, so r = .693
Now that we have our doubling rate of .693, we can use that r and our t as the 12th hour is t=11, because there are 11 more hours at the end of that first hour
So our initial population is again 15, and P = i•e^rt
P = 15•e^(.693×11) = 15•e^(7.624)
P = 15•2046.94 = 30,704
Answer:
C
Step-by-step explanation:
Rules for SN = must be a number from 1 and less than 10 times a power of 10
So our number becomes
2.22 x 10⁸ - It takes a move of 8 places to the right to make the number 222,000,000
