Suppose Ct is the concentration of a drug in the bloodstream t hours after the initial dose is administered. Suppose the initial dose C2was 217.6 ug/mL and suppose that every hour is administered 174 g/mL. If the body metabolizes and eliminates 54% of the concentration of the drug Ct over a period of one hour; determine C2, the concentration of the drug in the bloodstream two hours after the initial dose is administered.
Response at two decimal valors.

Let G be a group acting on a set S, and let H be a group acting on a set T. The product group G × H acts on the disjoint union S ∪ T as follows. For all g ∈ G, h ∈ H,
s ∈ S and t ∈ T,
(g, h) · s = g · s, (g, h) · t = h · t.
(a) Consider the groups G = C4, H = C5, each acting as usual. Calculate the cyclic polynomial ZC4×C5 .
(b) Explain why in general ZG×H = ZGZH.

This is a Matlab Question
Create MATLAB PROGRAM that can solve First Order Linear Differential Equation ( 1 example contains condition and the other does not have condition).
1. ty′ + 2y = t^2 − t + 1, y(1)=12
The correct answer is y(t) = 1/4 t^2 − 1/3 t + 1/2 + 1/12t^2
2. (x-1) dy/dx + 2y = (x+1)^2
The correct answer is y = (x(x+1) / x-1 ) + C(x+1) / x-1
The correct answer is

Let R be a ring (not necessarily commutative), and let X denote the set of two-sided ideals
of R.
(i) Show that X is a poset with respect to to set-theoretic inclusion, ⊂.
(ii) Show that with respect to the operations I ∩ J and I + J (candidates for meet and join;
remember that I+J consists of the set of sums, {i + j} where i ∈ I and j ∈ J) respectively,
X is a lattice.
(iii) Give an example of a commutative ring for which the corresponding X is not a Boolean
algebra, and one for which it is.
