Solve differential equation. Just explain the first 2 steps
lutik1710 [3]
(1) will write us of the following form

\dfrac{dy}{dx}+y^2\sin x=0\\ \\


(2) [do not it need explanation]

\dfrac{dy}{dx}=-y^2\sin x\\ \\


(3) Left place variable "y" and right place, variable "x" like this

\dfrac{dy}{y^2}=-\sin x\, dx\\ \\

(4) Integrate both members 

\displaystyle
\int \dfrac{dy}{y^2}=\int-\sin x\, dx\\ \\

(5) Solve us the integrals

-\dfrac{1}{y}= \cos x+C

(6) Isolate variable "y"

\boxed{y=-\dfrac{1}{\cos x+C}}

C: any cosntant

I do not understand this question? Using partial quotients, which would be the best choice for the first number to subtract in t
marysya [2.9K]

Answer:

B. 520

Step-by-step explanation:

Partial quotient is simply the method used to find the value of a quotient by dividing bits by bits until you get to the answer. For instance if you want to divide 124/4

Whatever closest multiple of 4 to 124 you remember, write it down. For instance I remember 80 first.

80 is the 20th multiple of 4 (80÷4 = 20).

Then subtract the number from the original number you want to divide

124 – 80 = 44

Again, write down the closest multiple of 44 you remember. To me is 40, and it is the 10th multiple.

Subtract 40 from 44 you have 4 left.

It's now easy to divide 4 by 4 which is 1.

To now get the quotient in total, you'll add up

20 + 10 + 1 = 31.

Therefore, to use partial quotient in this problem, the best choice to begin with will be 520 because it is the 20th multiple of 26. Although 780 is the 30th multiple of 26, 520 will be easier to remember. For this reason, it is the best choice.

Giving brainlist to whoever answers
ad-work [718]

Answer:

Hello! answer: x = 1

Step-by-step explanation:

If the circles each represent 1 then each sode has 6 circles but the other side has 3 circles sense this is balanced equal that means x must equal 1 for them both to equal 9 on each side because 6 + 3 = 9 Hope that explains well.

The question is below, 20 is not the correct answer​
pentagon [3]

Answer:

20

Step-by-step explanation:

<u>Given:</u>

  • m∠JKL = 3x + 5

<u>As per the picture:</u>

  • m∠JKL = m∠JKM + m∠MKL = 45 + x

<u>Comparing the two equations above:</u>

  • 3x+5 = 45 + x
  • 3x - x = 45 - 5
  • 2x = 40
  • x = 40/2
  • x = 20

x = 20 is the correct answer for this question

Otherwise something is wrong with the question.
