Răspuns:

<AOB = 43 ° și <BOC = 137 °

Explicație pas cu pas:

Găsiți diagrama atașată pentru o mai bună explicație a întrebării.

Din diagramă, <COP = <DOP + <COD

Deoarece <DOP = 90 ° și <COP = 133 °, la înlocuire

133 ° = 90 ° + <COD

<COD = 133 ° -90 °

<COD = 43 °

Deoarece <COD = <AOB (unghiuri direcționate opuse), deci <AOB = 43 °

Pentru <BOC:

Suma unghiurilor pe DBO dreaptă este de 180 °.

<BOC + <COD = 180 °

Dat <COD = 43 °

<BOC + 43 = 180 °

<BOC = 180 ° -43 °

<BOC = 137 °

Prin urmare, <AOB = 43 ° și <BOC = 137 °

Find the slope of the line passing through the points (-3, -8) and (4,6).
Dovator [93]

Answer:

<h2>slope = 2</h2>

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have

(-3;\ -8)\to x_1=-3;\ y_1=-8\\(4;\ 6)\to x_2=4;\ y_2=6

Substitute:

m=\dfrac{6-(-8)}{4-(-3)}=\dfrac{6+8}{4+3}=\dfrac{14}{7}=2

What is the coefficient of x^2 y^3 in the expansion of (2x+y)^5
Anna35 [415]

If it's x²y³ then we know it's the second term of the expansion, that known we can use the combination

C(5, 2) = 5!/(2!.3!) = 10

Then if we had something like

(a + b)^5 our second term would be 10a²b³ but as we can see it's "a²"

And in our case we have 2x as a

So we must do 2² too

2² = 4

10 . 4 = 40

Then our second term of the expansion would be

40x²y³
