If x=root 3+1/root 3-1 and y=root 3-1/root 3+1, then find the value of x2-xy+y2​

Answer»

Answer:

13

Step-by-step explanation:

x=(root 3+1)/(root3-1)

y=(root 3-1)/(root3+1)

SOLUTION :

x²-xy+y²

=(root 3+1)²/(root 3-1)² -(root 3-1)/(root 3+1)*(root 3+1)/(root 3-1)+(root 3-1)²/(root 3+1)²

="(3+1+2 root 3)²+(3+1-2 root 3)²"/(4-2 root 3)*(4+2 root 3)-1

=(4+3+4 root 3+4+3-4 root 3)/(2-root 3)*(2+root 3)-1

=(14/4-3)-1

=14-1

=13

Find the zero of the polynomial p(x)= ax-b. (a) is not equal to zero

Answer»

ANSWER:

Step-by-step explanation:

Hey friend,

Here's your required answer:-

=================================

p(X) = ax

p(x) = 0

ax = 0

x = 0/a

x = 0

{0 by SOMETHING is equals to 0}

Therefore,0 is the zero of the polynomial.

Checking:-

p(0) = a(0)

= 0

Hope it helps

Aditya devotes 6 hours to his studies everyday. He devotes 1 4/5 i.e. 9/5 hours to maths, 1 1/4 i.e. 5/4 hours to English and the remaining time to study other subjects. How much time does he spend on other subjects. Plz answer with full solution ​

Answer»

Answer:

2hrs 57mins

Step-by-step EXPLANATION:

TOTAL time devoted to study = 6 hrs

time devoted to MATHS = 9/5 hrs

time devoted to eng =5/4 hrs

time devoted to other sub = 6-(9/5+5/4)

=6-(36+25/20)

= 6 - 61/20

= 120-61/20

=59/20hrs

= 2 19/20hrs

= 2 hrs 57min

♕ ♕Only solve Question:-(iii)​

Answer»

<P>Step-by-step explanation:

5/x-1 +1/y-2 = 2

6/x-1 - 3/y-2 = 1

Let 1/x -1 be p and 1/y-2 be q

5P +q = 2 ____ eq 1

6p -3q = 1. _____ eq 2

On multiple eq 1 by 3 we get , 15p +3q = 6

On Solving eq we get 21q = 7

q = 7/21 = 1/3

on putting the VALUE of q in eq 2

6p -3(1/3) = 1

6p = 2

p = 1/3

Here , 1/x -1 = p

1/x-1 = 1/3

x -1 = 3

x = 4

Here, 1/y-2 = q

1/y -2 = 1/3

y-2 = 3

y =5

Kamala has gone for a hiking trip.she ended a hike at an elevation of 5000 ft above the sea level. She had started at an elevation of 5000 ft above sea level .which integer represents Kamala change in elevation

Answer»

Given:

STARTING ELEVATION of Kamala = 5000ft above sea level.

Ending elevation of Kamala = 5000ft above sea level.

To Find:

Which integer represents Kamala CHANGE in elevation.

Solution:

  • Kamala's starting and ending elevations are at same height above the sea level .
  • She could have trekked through a MOUNTAIN and came back to her initial height.
  • Since starting and ending elevations are same, there is no change in elevation.
  • Change in elevation = Start elevation - End elevation
  • Change in elevation = 5000ft - 5000ft = 0 ft.

Kamala's change in elevation is represented by 0.

Obviously, not. The word approximately itselfshows that the number of people were near about thesenumbers. Clearly, 51,000 could be 50.800 or 51,300but not 70,000. Similarly, 40 million implies muchmore than 39 million but quite less than 41 millionbut certainly not 50 million.can you send me the meaning of this​

Answer»

Answer:

The above passage is about the APPROXIMATE VALUES (nearest values )

In this passage maybe they were talking about the POPULATION.....

we can SAY approx. 51000 if the accurate value is 51300 or 50.800 it means we can use the approximate value for lower values(it means the difference will be less) only but not for higher values like in millions if we use approx.of 39million people we can say it as below than 40 or 41.... but we can't use as 50 million because there's a huge difference........

If abc is a triangle am is perpendicular and an is angle bisector

Answer»

Step-by-step EXPLANATION:

Step 1:

Suppose that  ANGLE  ''A'' =  2x.

Looking at the fact that  AN is bisector of angle  A you may write that

angle "BAN" = "NAC"  i.e. = x

Step 2:

In the triangle ( ΔABC) the total of all the angles must be 180 degrees, as per common law rules.

So the sum of all angles of triangle must be  ∠B  + ∠C + ∠A = 180°

Step 3: We have following missing values:-

65 + 30 + angle "A" = 180°

=180-( 65+30)

=180-(95)

=85 degrees.

You found value for angle "A"

Step 4:

Now you must do angle "A"/2 i.e.  x = 85 degrees /2

Step 5:

in triangle ABN another triangle ANC is the exterior angle so use this law of total of exterior angles to find out missing value.

Where; x + 65  =  angle "ANC"

85/2 + 56 = angle "ANC "

∠ANC = 215/2

Step 6:

After finding the angle LOOK at MNA =  180 degrees

Next you do this

180- (215/2) = 143/2

Step 7:

in the triangle AMN, this is the situation that; 143/2 + 90 +  angle MAN = 180°

thus; angle MAN = 90 - 143/2

Making answer  angle MAN = 35/2

final answer: 17.5 degrees

If a and b are acute angles and sin a equals to cos a find the value of sin c

Answer»

Answer:

Sin C ranges from 0 to 1 depending on the cases explained below

Step-by-step explanation:

For sinA = cosA and angles are acute, then A = 45°

Assuming this is a triangle, since A and B are acute and considering the POSSIBLE cases

1. B < A, here, this makes C an obtuse angle

2. B > A, here, this makes C an acute angle

3. B = A, here, this makes C a RIGHT angle

for B < A, sin C is positive (Acute is 1st quadrant) and ranges from 0 to 1 exclusively

for B > A, sin C is positive (Obtuse is 2nd quadrant) and ranges from 0.7 to 1 exclusively

for B = A, sin C = 1

ab parallel to cd and t transversal cuts e and f if ef and fq are the bisectors of angle aef and eff prove ep parallel fq​

Answer»

Step-by-step explanation:

AB PARALLEL CD and let EF be the TRANSVERSAL

therefore angle EGB = angle GHD

(forming corresponding angles)

therefore angle GHD = 35°

angle GHD = angle PHQ.... opposite angles

therefore angle PHQ = 35°

In Δ PHQ, angle P = 90° and angle PHQ = 35°

therefore angle PQH = 55°

.......(remaining angle of a triangle)
