The population at the beginning of day 6 is 9720
Step-by-step explanation:
The population of bacteria triples each day; if we call the population at the beginning of day 1, this means that the population at the beginning of day 2 is
At the beginning of day 3,
At the beginning of day 4,
So the generic population at the beginning of day n can be written as
where
is the population at the beginning of day 1
Therefore, by substituting t = 6, we find the population at the beginning of day 6:

I know the answer is 23 to f. but idk how to explain my thinking cause i just went "how many times does 15 go into 345" and as for c. idk the answer
Answer:
b = (r/m) - 3
Step-by-step explanation:
r = (3+b)m
r/m = 3+ b
(r/m) - 3 = b
Answer:
1. 2
2. 30
Step-by-step explanation:
1. The weird circle looking thing essentially means you're putting p(x) inside of q(x). This means you take the x in q(x) and replacing with the entire p(x)
so q(x) = -3x - 4
(q °p)(x) = -3 (-2x+4) -4 sorry I can't find the actual circle thing symbol
now distribute to get the simplified equation:
= 6x -12 -4
= 6x - 16
because you're doing (q - p )(3), you would plug 3 for x into the new equation
6(3) - 16 = 2
and thats you're answer for the first one
for the second one its the other way around, so you're putting all of q(x) into p(x)
take p(x) : -2x+4
and now replace the x with the entire q(x)
so (p - q)(x) = -2 (-3x-4) +4
simplify: = 6x+8+4 = 6x+12
so now since we're doing (p-q)(3), we need to plug in 3 for x in the new equation
= 6(3)+12 = 30
lmk if those were wrong or if my explanation was unclear, there's another way I can explain it even though its the same process :)
