Mathematics
1 answer:
julsineya [31]3 years ago
5 0

Answer:

a. 22.5953 b. 3.6

Step-by-step explanation:

A. When a number is in parentheses and directly beside another number it means multiple. so you simply multiply to two together.

B. When a number is in parentheses but has a division sign or forward slash in front of it it is simply keeping the number separate as not to create confusion so just divide them.

ps. when you teacher says shoe work he/she means dint just write an answer. They mean write out beside your answer "2.43 x 9.71 = 22.5953" & "4.68 ÷ 1.3 = 3.6"

5. Find the general solution to y'''-y''+4y'-4y = 0
CaHeK987 [17]

For any equation,

a_ny^(n)+\dots+a_1y'+a_0y=0

assume solution of a form, e^{yt}

Which leads to,

(e^{yt})'''-(e^{yt})''+4(e^{yt})'-4e^{yt}=0

Simplify to,

e^{yt}(y^3-y^2+4y-4)=0

Then find solutions,

\underline{y_1=1}, \underline{y_2=2i}, \underline{y_3=-2i}

For non repeated real root y, we have a form of,

y_1=c_1e^t

Following up,

For two non repeated complex roots y_2\neq y_3 where,

y_2=a+bi

and,

y_3=a-bi

the general solution has a form of,

y=e^{at}(c_2\cos(bt)+c_3\sin(bt))

Or in this case,

y=e^0(c_2\cos(2t)+c_3\sin(2t))

Now we just refine and get,

\boxed{y=c_1e^t+c_2\cos(2t)+c_3\sin(2t)}

Hope this helps.
