Basically what you have to do is multiply the two numbers that are mentioned and that will be your answer.
This is because the item will have the same amount or length and you just need to find what it will be with multiple ones.
Next time you could highlight keywords that help you understand if you are supposed to multiply, divide, subtract, or add.
Answer:
14.7
Step-by-step explanation:
Perhaps your equation is ...
f(t) = N·e^(-0.2174t)
We want f(6) = 4, so ...
4 = N·e^(-0.2174·6) = N·e^-1.3044 ≈ 0.2713N
N = 4/0.2713 = 14.7 . . . . milligrams
The dose amount was about 14.7 mg.
Splitting up [0, 3] into 
equally-spaced subintervals of length 
gives the partition
![\left[0, \dfrac3n\right] \cup \left[\dfrac3n, \dfrac6n\right] \cup \left[\dfrac6n, \dfrac9n\right] \cup \cdots \cup \left[\dfrac{3(n-1)}n, 3\right]](https://tex.z-dn.net/?f=%5Cleft%5B0%2C%20%5Cdfrac3n%5Cright%5D%20%5Ccup%20%5Cleft%5B%5Cdfrac3n%2C%20%5Cdfrac6n%5Cright%5D%20%5Ccup%20%5Cleft%5B%5Cdfrac6n%2C%20%5Cdfrac9n%5Cright%5D%20%5Ccup%20%5Ccdots%20%5Ccup%20%5Cleft%5B%5Cdfrac%7B3%28n-1%29%7Dn%2C%203%5Cright%5D)
where the right endpoint of the 
-th subinterval is given by the sequence
for 
.
Then the definite integral is given by the infinite Riemann sum
Answer:
The domains are not the same
Step-by-step explanation:
The domains are not the same because in the first graph, the left part of the graph is always approaching 2, not reaching it, while the right side is extending infinitely. In the second graph, the left side DOES reach three except it doesn't cross it.
So the notation for the first line would be
2<x<infinity
2\leq x <infinity
Answer:
Step-by-step explanation:
30/5 : x/2
(30×2)/5 = x
