WILL GIVE BRAINLIEST AND 20 POINTS! Find m∠AOB given x = 81° and y = 41°.

morpeh [17]

Step-by-step explanation:

Given,

x = 81° and y = 41°

Also given in the figure that,

m∠AOB = x + y

Therefore, value of m∠AOB,

m∠AOB = x + y

= 81° + 41°

= 122° (Ans)

Integral of (3x-2)/(x-1)^2

Goryan [66]

(3x−2)/(x−1)^2=A/(x−1) + B/x(x−1)^2
 =[A(x−1)+Bx(x−1)] / 2 3x-2=A(x-1)+Bx
3x-2=x(A+B)-A
A+B=3
-A=-2=>A=2
A+B=3=>2+B=3=>B=1

lets check our partial fraction we have 2/(x−1) + x/(x−1)^2 = [2(x−1)+x] / (x−1)^2
 =(3x−2) / (x−1)^2

Construct a triangle POT having side OT= 7cm

Sladkaya [172]

Answer:

Answer is No.

Reason:

One side of the triangle has to be less than the sum of the other two sides and greater than the magnitude of their difference.

i.e.,

Rule 1: (side1 + side2) > side3

Rule 2: Side3 < |side1 - side2|

Lets check the fact by adding / subtracting two sides and comparing with the third one..

Case1: 7+ 8 = 15 = length of third side. Rule1 fails

Case2:

8+15 > 7 Rule1 sucess

15–8 = 7 = length of third side. Rule 2 fails.

Case3:

7+15>8 Rule1 success

15–7=8 = length of third side. Rule 2 fails.

So, considering the rules and checking the facts..

It is impossible to create a triangle with above 3 sides.

Orange juice is a common breakfast drink that contains citric acid. If the hydronium ion concentration is 3.4 × 10-4 in orange j

Lelu [443]

Answer:

3.5

Step-by-step explanation:

Given : the hydronium ion concentration is $3.4*10^{-4}$ in orange juice

To Find: what is the pH?

Solution :

Definition of pH : pH is the negative log of the molar hydrogen ion concentration

Formula of pH : - log [H+]

Since we are given H+ = $3.4*10^{-4}$

So, substituting this value in formula :

$pH = - log [3.4*10^{-4}]$

$pH = - log [3.4*0.0001]$

$pH = - log [0.00034]$

$pH = 3.468$

pH = 3.468≈3.5

Thus the pH is 3.5
