Answer»

Given: In triangle ABC, D and E are midpoints of AB and AC respectively.

To Prove:

DE || BC

DE = 1/2 BC

Construction: Draw CR || BA to meet DE produced at R. (Refer the above figure)

∠EAD = ∠ECR. (Pair of alternate angles) ———- (1)

AE = EC. (∵ E is the mid-point of side AC) ———- (2)

∠AEP = ∠CQR (Vertically opposite angles) ———- (3)

Thus, ΔADE ≅ ΔCRE (ASA CONGRUENCE rule)

DE = 1/2 DR ———- (4)

But, AD= BD. (∵ D is the mid-point of the side AB)

Also. BD || CR. (by construction)

In quadrilateral BCRD, BD = CR and BD || CR

Therefore, quadrilateral BCRD is a parallelogram.

BC || DR or, BC || DE

Also, DR = BC (∵ BCRD is a parallelogram)

⇒ 1/2 DR = 1/2 BC

The Converse of MidPoint Theorem

The line drawn through the mid–point of one side of a triangle and parallel to another side bisects the third side.

32.	I cant please answer fast I cant fail
Answer» Step-by-step explanation: From the formula of MEAN, we know that Mean = SUM of values/ Total number of values Mean for boys = 75+41+25+22+7+0+43+12+45+70 /10 = 34 Mean for girls = 50+32+15+56+50+18+81+22+55/10 = 46 Mean shows that average downloads of music by both the genders Now, to calculate median, we need to arrange the data in ascending order For boys : 0, 7, 12, 22, 25, 41, 43, 45, 70, 75 For girls : 15, 18 22, 32, 50, 50, 55, 56, 81, 81 Now median is the exact MIDDLE VALUE but for EVEN number of data, we apply formula Median for boys = 25 + 41 /2 = 33 Median for girls = 50 + 50/ 2 = 50 This shows that the middle value for music downloads for both the genders

32.

I cant please answer fast I cant fail

Answer»

Step-by-step explanation:

From the formula of MEAN, we know that

Mean = SUM of values/ Total number of values

Mean for boys = 75+41+25+22+7+0+43+12+45+70 /10 = 34

Mean for girls = 50+32+15+56+50+18+81+22+55/10 = 46

Mean shows that average downloads of music by both the genders

Now, to calculate median, we need to arrange the data in ascending order

For boys : 0, 7, 12, 22, 25, 41, 43, 45, 70, 75

For girls : 15, 18 22, 32, 50, 50, 55, 56, 81, 81

Now median is the exact MIDDLE VALUE but for EVEN number of data, we apply formula

Median for boys = 25 + 41 /2 = 33

Median for girls = 50 + 50/ 2 = 50

This shows that the middle value for music downloads for both the genders

if 2 is the root of quadratic equation 3xsquare+px-p=0and quadratic equation 4xsquare-2px+k=0 has equal roots find k

Answer»

<P>Step-by-step explanation:

2 is the root of quadratic equation 3x² + px - 8 = 0………….(1)

& 4x² - 2px + k = 0 has equal roots ………….(2)

On putting the value of given root i.e X = 2 in eq 1 .

3x² + px - 8 = 0

3(2)² + p(2) − 8 = 0

3 × 4 + 2P - 8 = 0

12 + 2p − 8 = 0

4 + 2p = 0

2p = - 4

p = - 4/ 2 = -2

p = - 2

Hence the value of p is - 2.

On putting the value of p = - 2 in eq 2,

4x² - 2px + k = 0

4x² - 2(- 2)x + k = 0

4x² + 4x + k = 0

On comparing the given equation with ax² + bx + c = 0

Here, a = 4, b = 4 , and c = k

D(discriminant) = b² – 4ac

Given : Quadratic equation has equal roots i.e D = 0

b² – 4ac = 0

4² – 4(4)(k) = 0

16 – 16k = 0

16 = 16k

k = 16/16 = 1

k = 1

Hence, the value of k is 1 .

★★ NATURE OF THE ROOTS

If D = 0 roots are real and equal

If D > 0 roots are real and distinct

If D < 0 No real roots

December 20, 2019Sanyog Sravani

SHARE

ANSWER

Let the FRACTION be qp

So q=p+7

q−6p+17=2

⇒p+7−6p+17=2

⇒p+1p+17=2

⇒p+17=2p+2

⇒p=15

q=15+7=22

So qp=2215.
