Answer:

Step-by-step explanation:

15x - 10 = 20

15x = 20 + 10

15x = 30 (divide both sides by 15 to get x)

15x/15 = 30/15

x = 2

Answer:

y & x = 2, but since you only need y, y=2

Step-by-step explanation:

15 x 2 = 30

5 x 2 = 10

30 - 10 = 20

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.

Find the following products: a) (−12) × (−11) × (10) b) (−25) × (−8) × (−2) WITH EXPLANATION
Gnoma [55]

Step-by-step explanation:

Hey, there!!

a. (-12)×(-11)×10

Here, (-)×(-)=(+)

(-12)×(-11)=132

so,

=132×10

=1320.

For b.

(-25)×(-8)×(-2)

(-)×(-)=(+)

(-25)×(-8)=200

so,

=200×(-2) { (+)×(-)=(-)}.

= -400.

Therefore, the answer of a. no. is 1320, and no. b is (-400).

Answer:

C. 28.6units^2, 0.28

Step-by-step explanation:

<em><u>To find the white portion's area, you add 44 and 47, then multiply it by π</u></em>r^2:

44 + 47 = 91

\frac{91}{360}(3.14)(6)^2

A = 28.574   →    A = 28.6

<em><u>There are 7 parts of the circle, and 2 of them are white. So divide 2 by 7:</u></em>

2 ÷ 7 = 0.28
