FACTORISATION

---------------------------

a² + b² + 2AB + 2bc + 2ca

=> a² + b² + c² + 2ab + 2bc + 2ca - c² [ADDING and subtracting c².]

=> (a² + b² + c² + 2ab + 2bc + 2ca) - c²

=> (a + B + c)² - c²

=> (a + b + c + c)(a + b + c - c). [Using identity => a² - b² = (a + b)(a - b)]

=> (a + b + 2c)(a + b)

SOLUTION:-

There is a mistake in this question. It should be like this - The measure of an angle is two third of it's complement.

Let one of the complementary ANGLES be 'x'

Then the other angle will be 2X/3

As we know that the two angles are complementary when they add up to 90 degrees.

So, according to the question.

x + 2x/3 = 90°

Taking L.C.M. and solving it, we GET.

(3x + 2x)/3 = 90

5x/3 = 90

5x = 90*3

5x = 270

x = 270/5

x = 54

So. measure of one of the angles is 54° and the other is

90 - 54 = 36°

The name QUADRATIC comes from "quad" MEANING square, because the variable gets squared (like X2).

It is also called an "Equation of DEGREE 2" (because of the "2" on the X)

Vertex is(4,0) and focus is (2,0) . The distance between focus and vertex is 2 which is ONE FOURTH of LATUS RECTUM. Latus rectum=8. (y-0)^2=8(x-4) => y^2= 8x-32 is the equation of the parabola.

0.625 is your ANS

1000M = 1km

5000m = 5KM

5236m = 5km 236 m

Let the correct time to COMPLETE the journey be x MIN.

DISTANCE covered in (x + 11)

min.= Distance covered in (x + 5) min at 50 km/hr

∴ (x+11)60 * 40

= (x+5)60 * 50

=x = 19 min.

Answer:

HOPE it HELPS...

Please MARK the brainliest....

Step-by-step EXPLANATION:

Here is your ANSWER.

let number be x.

x=3q+1 -----1

Q=2p+1 -----2

EQ 2 is possible only if q is odd,

so PUT q=1, 3,5,.....2n-1

if q=3

x=10

if 6 divides 10 ,it will leave reaminder as 4

if q=5

x=16

again remainder will be 4.

X+1=0
x=-1

p(-1)=(-1)³ + 3×(-1)²+ 5×(-1) +6
= -1 + 3 - 5 +6
= 2-1
= 1

It is not a factor.

Given: 4^x-4^(x-1)

=> (4–1)*4^(x-1)

=> 3*4^(x-1)

=>3*4^(x-1)=24 (GIVEN)

=> 4^(x-1)=8

=> 2^(2*(x-1))=2^3

by EQUATING the powers,

2x-2=3

=> 2x=5.

2,019 IS NOT PRIME...

I NEED Euler’s help...

φ(2,019)=2,019×(2/3)×(672/673)=1,344【2019=3×673】

∴Euler said : a^1344 ≡ 1 mod 2019

Now note that 2017=1344+673

I need a PATTERN..There are 2,017 terms...

Working from the front...

ALL in mod...2019

1^2017≡ 1

2^2017≡2^673

3^2017≡3^673

4^2017≡4^673

.........

99^2017≡99^673

1008^2017≡1008^673

.............…

Working from the back...

2017^2017≡2017^673≡(2019–2)^673≡-(2^673)

2016^2017≡2016^673≡-(3^673)

2015^2017≡2015^673≡-(4^673)....

...............

1920^2017≡(2019–99)^673≡ -(99)^673

1008^2017≡(2019–1011)^673≡-1011^673

1018^2017≡(2019–1001)^2017≡-(1001^673)

1019^2017≡(2019–1000)^673≡-(1000^673).

OBSERVATION :

2nd cancell off with 2017th term

3rd cancell off with 2016th term

.........and so on

∴The only uncanclled term is the FIRST TERM.

∴THE GIVEN series ≡ 1 mod 2019

Heya!

Here is yr answer....


HCF of 900 & 300


According to EUCLID'S DIVISION LEMMA.....


a = bq + r

a = divident => 900

b = divisor => 300

q = QUOTIENT => ?

r = Remainder => ?


Now,

900 = 300 × 3 + 0

Here, r = 0

So, the divisor is the HCF


Therefore, 300 is the HCF of 900 & 300


Hope it hlpz.

When connected in PARALLEL, 1/EQUIVALENT resistance =1/R1+1/R2=1/3 => R1+R2/R1R2=1/3=> R1R2/R1+R2=3.
When connected in SERIES,equivalent resistance=R1+R2=16 ohm.
=>R1R2=48.
=> R1+48/R1=16.
=> R1^2+48 =16R1
=>R1^2-16R1+48=0
=> R1=12ohm and R2=4ohm.

Largest 2 digit NUMBER is 99. So we KEEP going backwards 99, 98, 97 ... till we hit a perfect square.

The first perfect square we hit will be:

81 (which is the square of 9)

Then

64 (which is the square of 8)

then

49 (which is the square of 7)

...

27. Substitute x=tanA we GET tan^-1(3tanA-tanA^3)/(1-3tanA^2)=tan^-1(TAN3A) as the above fraction is formula for tan3A. it is EQUAL to 3A=3tan^-1x. on INTEGRATING we get as above 3xtan^-1x-3/2log(1+x^2)+C.

2401 = (7)^4

so yr FIRST ANSWER is 4
