Answer» QUESTION: What is the SLOPE of the LINE that passes through the points ( 5,-10 ) and ( 11 , -12 ). Answer: ● To find the slope of the straight line when 2 points are given , $slope = \frac{ y_{2} - y_{1}}{ x_ {2} - x_{1} }$ $= \frac{ - 12 - ( - 10)}{11 - 5}$ $= \frac{ - 12 + 10}{6}$ $= \frac{ - 2}{6}$ $= \frac{ - 1}{3}$ Be Delighted :)

Answer»

QUESTION:

What is the SLOPE of the LINE that passes through the points ( 5,-10 ) and ( 11 , -12 ).

Answer:

● To find the slope of the straight line when 2 points are given ,

$slope = \frac{ y_{2} - y_{1}}{ x_ {2} - x_{1} }$

$= \frac{ - 12 - ( - 10)}{11 - 5}$

$= \frac{ - 12 + 10}{6}$

$= \frac{ - 2}{6}$

Answer» Answer: ffffffffffffffffffffffffffffffffffffffffffffIn a right triangle, the square of the HYPOTENUSE is EQUAL to the sum of the squares of the other two sides of the triangle. Now, In a right triangle, side opposite to the 90° is ALWAYS the hypotenuse. The square of the side opposite of the 90° in a right triangle is equal to the sum of squares of the other two sides. Here, ∆ ABC is a right triangle, right angled at B. AC is the hypotenuse of the right ∆ ABC. So, the square of AC = the sum of the squares of the other two sides AB and BC. that is, AC² = AB² + BC² or, hypotenuse (h)² = perpendicular (p) ² + base (b)² [Pythagoras Theorem] Hence, proved. Step-by-step explanation:

Find the solution of the differe kintial equations p2+y2 =1

Answer»

Answer:

ffffffffffffffffffffffffffffffffffffffffffffIn a right triangle, the square of the HYPOTENUSE is EQUAL to the sum of the squares of the other two sides of the triangle.

Now,

In a right triangle, side opposite to the 90° is ALWAYS the hypotenuse. The square of the side opposite of the 90° in a right triangle is equal to the sum of squares of the other two sides.

Here,

∆ ABC is a right triangle, right angled at B. AC is the hypotenuse of the right ∆ ABC.

So, the square of AC = the sum of the squares of the other two sides AB and BC.

that is, AC² = AB² + BC²

or, hypotenuse (h)² = perpendicular (p) ² + base (b)² [Pythagoras Theorem]

Hence, proved.

Prove that the sum of two sides of a triangle is alwayes greater than the third angle

Answer»

Answer:

Construction: In ΔABC, EXTEND AB to D in such a WAY that AD=AC.

In ΔDBC, as the angles OPPOSITE to equal sides are always equal, so,

∠ADC=∠ACD

Therefore,

∠BCD>∠BDC

As the sides opposite to the greater ANGLE is LONGER, so,

BD>BC

AB+AD>BC

Since AD=AC, then,

AB+AC>BC

Hence, sum of two sides of a triangle is always greater than the third side.

31.	Soove by factoristion method x²-x-a (a + 1) = 0
Answer» $\large{\mathbb{\purple{\boxed{\green{\underbrace{\overbrace{\red{\boxed{\green{♪Answer♪}}}}}}}}}}$ Yes! When the x2 coefficient is 1 , we call this a monic quadratic, in this case. The coefficient of x, the minus one, here, is the negative of the sum of the roots. The constant term is the product of the roots. If the roots are named p and Q, then we have: p+q= 1 and pq=-a• (a+1). Obviously, (a+1) -a = 1, so -a and (a+1) are the TWO roots. You can also see this by subtracting the constant term from both SIDES and multiplying out the r.h.s or factoring the l.h.s. and identifying the parts in relation to the 1′s and x's. Like so: x2 − x = a2 + a , -a = x; x∙(x−1) = (a+1)∙a , (a+1) = x. Whenever you use an unconventional technique like this one, you should always check that your answer is complete and VALID. So we have -a and a+1 as roots. They are distinct unless, a+1 = -a, or a = -1/2. When a =-1/2 both roots are equal ( double ). All other values of “a" give distinct roots. Also: (x− −a)∙(x− (a+1)) = (x+a)∙(x−a−1) = x2−AX−x + ax −a(a+1) = x2 − x − a∙(a+1) So, the two roots produce the equation. In checking, sometimes you will have a nonzero constant, other than one, multiplying the equation. So long as you can legally cancel the extra multiplier, the check is valid.

Answer» Answer: (SIN x+cos x)^2 Step-by-step explanation: 1+sin 2x=(sin x)^2+(cos x)^2+2(sin x)(cos x) We know that from TRIGONOMETRY, sin x^2+cos x^2=1 & (a+b)^2=a^2+b^2+2ab From this,we conclude that 1+sin 2x=(sin x+cos x)^2

39.

4.sin 2xs dx equals1+sin2x

Answer»

Answer:

(SIN x+cos x)^2

Step-by-step explanation:

1+sin 2x=(sin x)^2+(cos x)^2+2(sin x)(cos x)

We know that from TRIGONOMETRY,

sin x^2+cos x^2=1 &

(a+b)^2=a^2+b^2+2ab

From this,we conclude that

1+sin 2x=(sin x+cos x)^2

घरेलू पर्यटन करता है इसके महत्व बताइए

Answer»

Answer:

5(x-y)+(X+y)/(X+y)(x-y)=2

5x-5y+x-y/x²-y²=2

6x-6y=2x²-2y²

6(x-y)=2(x+y)(x-y)

6/2=(X+y)

42.	किसी समांतर चतुर्भुज के दो आसन्न कोणों के माप बराबर हैं। समांतर चतुर्भुज के सभी कोणों की माप ज्ञात कीजिए
Answer» उत्तर : ›»› समांतर चतुर्भुज के सभी कोणों का माप 90° हैं। दिया हुआ : समांतर चतुर्भुज के दो आसन्न कोणों के माप बराबर हैं। ज्ञात करना : समांतर चतुर्भुज के सभी कोणों का माप। समाधान : आइए हम मान लें कि समांतर चतुर्भुज के बराबर कोण "X" हैं। इसलिए, समांतर चतुर्भुज के सभी कोण "x" होंगे क्योंकि एक समांतर चतुर्भुज के विपरीत कोण समान हैं। जैसा कि हम जानते हैं कि समांतर चतुर्भुज के सभी चार कोणों का योग 360° है। → x + x + x + x = 360 → 2X + x + x = 360 → 3x + x = 360 → 4X = 360 → x = 360/4 → x = 90 इसलिए, समांतर चतुर्भुज के सभी कोणों का माप 90° हैं। सत्यापन : समांतर चतुर्भुज के सभी चार कोणों का योग 360° है। → 90 + 90 + 90 + 90 = 360 → 180 + 90 + 90 = 360 → 270 + 90 = 360 → 360 = 360 यहाँ, LHS = RHS इसलिए सत्यापित है।

किसी समांतर चतुर्भुज के दो आसन्न कोणों के माप बराबर हैं। समांतर चतुर्भुज के सभी कोणों की माप ज्ञात कीजिए

Answer»

उत्तर :

›»› समांतर चतुर्भुज के सभी कोणों का माप 90° हैं।

दिया हुआ :

समांतर चतुर्भुज के दो आसन्न कोणों के माप बराबर हैं।

ज्ञात करना :

समांतर चतुर्भुज के सभी कोणों का माप।

समाधान :

आइए हम मान लें कि समांतर चतुर्भुज के बराबर कोण "X" हैं। इसलिए, समांतर चतुर्भुज के सभी कोण "x" होंगे क्योंकि एक समांतर चतुर्भुज के विपरीत कोण समान हैं।

जैसा कि हम जानते हैं कि

समांतर चतुर्भुज के सभी चार कोणों का योग 360° है।

→ x + x + x + x = 360

→ 2X + x + x = 360

→ 3x + x = 360

→ 4X = 360

→ x = 360/4

→ x = 90

इसलिए, समांतर चतुर्भुज के सभी कोणों का माप 90° हैं।

सत्यापन :

समांतर चतुर्भुज के सभी चार कोणों का योग 360° है।

→ 90 + 90 + 90 + 90 = 360

→ 180 + 90 + 90 = 360

→ 270 + 90 = 360

→ 360 = 360

यहाँ, LHS = RHS

इसलिए सत्यापित है।

ABCD is a rhombus.

⇒AC=BC ........(1)(given)

BC=AB .....(2)(side of rhombus)

From EQNS(1) and (2)

AC=BC=AB

⇒△ABC is equilateral triangle.

So, ∠ABC=60

∠BCA=60

..........(3)

∠CAB=60

..........(4)

SIMILARLY, in △ADC,AD=DC(sides of a rhombus)

AD=BC

But BC=AC

∴AD=AC

∴AD=DC=AC

∴DAC is an equilateral triangle.

⇒∠CAD=60

......(5)

⇒∠ADC=60

⇒∠DCA=60

From eqns(4) and (5),
