<span>y" + 9y = 0
m^2 + 9 = 0
m = ± 3i
yH = C1 cos 3t + C2 sin 3t
yP = C3 t sin 3t + C4 t cos 3t
hope this helps </span>
solve for "r", now, the value you'd get, is a decimal format of it, thus, just multiply it by 100 to get the percent in % form
First we put the sentence into a function
9/10 * x + 6= 51Well then we solve<span>.</span><span>9/10* x= 51-6
9/10*x= 45
(<span>for</span> me is easier to make the fraction into a decimal...)
0.9*x= 45
x=45/0.9
x= 50
We check
9/10 * 50 + 6= 51
45+6=51
51=51
So the answer is x= 50</span>
