Answer:
We readily separate the variables and integrate:
∫dP/P=∫(k+bcos2t)dt
ln P=kt+(b/2)*sin2t+ln C
Clearly C = Po, so we find that P(t) = Poexp(kt + (b/2)* sin 2t). The 271- curve with the typical numerical values P_o = 100, k = 0.03, and b = 0.06. It oscillates about the curve which represents natural growth with P_o and k = 0.03. We see that the two agree at the end of each full year.

Answer:
18
Step-by-step explanation:
There is two pints for every quart so multiply 9*2=18
Let a be the constant the quadratic term
y = ax²
32 = a(2)²
a = 8
Using the same method for each pair of x and y, we can confirm that the value of a is 8.
The answer is A.
I'm assuming that you meant 4x+1=3x?
Subtracting 4x, we get 1=-x. Multiplying by -1, we get x=-1 as the solution.
