Find thebarea of quadrilateral ABCD . AB= 4, AD= 17cm, DC=8cm,BC=?

Answer»

ANSWER:

if we make its diagram we get a TRAPEZIUM and area of trapezium =1/2 (sum of two parallel side )×h

Step-by-step explanation:

1st we find bc which is our HEIGHT

by APPLYING pythagoras theorem

h2= p2 + b2

(17)2=p2 +(8)2

289=p2+64

p2=225

p=15=bc

now we have to apply formula of area of trapezium =1/2 (sum of two parallel side)×h

1/2 (4+8)×15

6×15 = 90

verify if 1 and minus 3 hours use of the polynomial 3 x cube + 5 x square - 11 X + 3 then factorise the polynomial

Answer»

Step-by-step EXPLANATION:

$3 {x}^{3} + 5 {x}^{2} - 11x + 3$

is the polynomial

Substitute x=>1 in this polynomial =>

$3 {(1)}^{3} + 5 {(1)}^{2} - 11(1) + 3 = 3 + 5 -$

$11 + 3 = 0$

So 1 is the root of this polynomial.

Substitute x=>-3 in this polynomial =>

$3 {( - 3)}^{3} + 5 {( - 3)}^{2} - 11( - 3) + 3 = >$

$3( - 27) + 5(9) - 11( - 3) + 3 = - 81$

$+ 45 + 33 + 3 = - 81 + 81 = 0$

HENCE -3 is also the root of polynomial Hence proved . Hope it helps you.

Answer» Answer: GIVEN, TOTAL NUMBER participants = 63 Total prize money distributed = RS 3000 Winner gets a prize of Rs 100 Loser gets a prize of Rs 25 Number of winners = ? Let the number of winners = m Since, Number of winners + Number of LOSERS = Total number of participants Or, m + Number of losers = 63 By transposing ‘m’ to RHS, we get Number of losers =63–m Now, Total Prize money distributed to winners = Number of winners X prize money distributed to each winner =m×100=100m Total prize money distributed to losers = Number of losers X prize money distributed to each loser =(63–m)×25=(63×25)–25m=1575–25m Now, Total Prize money of winners + Total Prize money of losers = Total prize money By substituting the total prize money distributed to winners and total prize money distributed to losers, we get 100m+1575–25m=3000 ⇒100m–25m+1575=3000 By transposing 1575 to RHS, we get 100m–25m=3000–1575 ⇒75m=1425 After dividing both sides by 75, we get 75m75=142575 Or, m=19 Thus, number of winners = 19 Answer

24.

Please answer this question fast 50 pts.....Question 17...

Answer»

Answer:

GIVEN, TOTAL NUMBER participants = 63

Total prize money distributed = RS 3000

Winner gets a prize of Rs 100

Loser gets a prize of Rs 25

Number of winners = ?

Let the number of winners = m

Since,

Number of winners + Number of LOSERS = Total number of participants

Or, m + Number of losers = 63

By transposing ‘m’ to RHS, we get

Number of losers =63–m

Now, Total Prize money distributed to winners

= Number of winners X prize money distributed to each winner =m×100=100m

Total prize money distributed to losers

= Number of losers X prize money distributed to each loser

=(63–m)×25=(63×25)–25m=1575–25m

Now, Total Prize money of winners + Total Prize money of losers = Total prize money

By substituting the total prize money distributed to winners and total prize money distributed to losers, we get

100m+1575–25m=3000

⇒100m–25m+1575=3000

By transposing 1575 to RHS, we get

100m–25m=3000–1575

⇒75m=1425

After dividing both sides by 75, we get

75m75=142575

Or, m=19

Thus, number of winners = 19 Answer

find value of x + Y + Z if X square + Y square + Z square equal to 18 and xy + Y Z plus ZX is equals to 9

Answer»

ANSWER:

$\green{x+y+z=6}$

Step-by-step explanation:

$\boxed{<klux>GIVEN</klux>}$

$x {}^{2} + y {}^{2} + z {}^{2} = 18$

$xy + yz + zx = 9$

$\boxed{Tofind}$

value of

$x + y + z$

$\boxed{Answer}$

using identity

$(x + y + z) {}^{2} = x {}^{2} + y {}^{2} + z {}^{2} + 2xy + 2yz + 2zx$

$(x + y + z \: ) = x {}^{2} + y {}^{2} + z {}^{2} + 2(xy + yz + zx)$

now PUTTING the given values, we GET

$(x + y + z) {}^{2} = 18 + 2(9)$

$(x + y + z) {}^{2} = 18 + 18$

$(x + y + z) {}^{2} = 36$

$x + y + z = \sqrt{36}$

$x + y + z = 6$

Answer» Answer: 1)representation of no. 1.5 in no. line is easy , just draw a line and plot the points 1 and 2 , then plot 1.5 b/w 1 and 2 2) rational no. b/w 2/5 and 3/4 are 1/2, 11/20, 3/5, 13/20, 7/10 3)six rational no. b/w 3 and 4 are 22/7, 23/7, 24/7, 25/7, 26/7, 27/7 4)Let’s take n= numbers required to be find out So, Thus, 16 rational numbers are: (a + d), (a + 2D), (a + 3d), (a + 4d), (a + 5d), (a + 6d), (a + 7D), (a + 8D), (a + 9d), (a + 10d), (a + 11d), (a + 12d), (a + 13d), (a + 14d), (a + 15d) and (a + 16d) So, (a + d) = (2.1 + 0.005) = 2.105 (a + 2d) = [2.1 + (2 × 0.005)] = 2.110 (a + 3d) = [2.1 + (3 × 0.005)] = 2.115 (a + 4d) = [2.1 + (4 × 0.005)] = 2.120 (a + 5d) = [2.1 + (5 × 0.005)] = 2.125 (a + 6d) = [2.1 + (6 × 0.005)] = 2.130 (a + 7d) = [2.1 + (7 × 0.005)] = 2. 135 (a + 8d) = [2.1 + (8 × 0.005)] = 2. 140 (a + 9d) = [2.1 + (9 × 0.005)] = 2. 145 (a + 10d) = [2.1 + (10 × 0.005)] = 2. 150 (a + 11d) = [2.1 + (11 × 0.005)] = 2. 155 (a + 12d) = [2.1 + (12 × 0.005)] = 2. 160 (a + 13d) = [2.1 + (13 × 0.005)] = 2. 165 (a + 14d) = [2.1 + (14 × 0.005)] = 2. 170 (a + 15d) = [2.1 + (15 × 0.005)] = 2. 175 (a + 16d) = [2.1 + (16 × 0.005)] = 2. 180 Thus, the rational numbers between 2.1 and 2.2 are 2.105, 2.110, 2.115, 2.120, 2.125, 2.130, 2.135, 2.140, 2.145, 2.150, 2.155, 2.160, 2.165, 2.170, 2.175, 2.180,

Short Answer Type Questions Slab-D)Represent each of the following rational numbers onthe number line:(11) (iii) 1.5 (1)5. Find five rational numbers between 2 upon 5 and 3 upon 4 6. Find six rational numbers between 3 and 4.7. Insert 16 rational numbers between 2.1 and 2.2.

Answer»

Answer:

1)representation of no. 1.5 in no. line is easy , just draw a line and plot the points 1 and 2 , then plot 1.5 b/w 1 and 2

2) rational no. b/w 2/5 and 3/4 are

1/2, 11/20, 3/5, 13/20, 7/10

3)six rational no. b/w 3 and 4 are

22/7, 23/7, 24/7, 25/7, 26/7, 27/7

4)Let’s take

n= numbers required to be find out

So,

Thus, 16 rational numbers are:

(a + d), (a + 2D), (a + 3d), (a + 4d), (a + 5d), (a + 6d), (a + 7D), (a + 8D), (a + 9d), (a + 10d), (a + 11d), (a + 12d), (a + 13d), (a + 14d), (a + 15d) and (a + 16d)

So,

(a + d) = (2.1 + 0.005) = 2.105

(a + 2d) = [2.1 + (2 × 0.005)] = 2.110

(a + 3d) = [2.1 + (3 × 0.005)] = 2.115

(a + 4d) = [2.1 + (4 × 0.005)] = 2.120

(a + 5d) = [2.1 + (5 × 0.005)] = 2.125

(a + 6d) = [2.1 + (6 × 0.005)] = 2.130

(a + 7d) = [2.1 + (7 × 0.005)] = 2. 135

(a + 8d) = [2.1 + (8 × 0.005)] = 2. 140

(a + 9d) = [2.1 + (9 × 0.005)] = 2. 145

(a + 10d) = [2.1 + (10 × 0.005)] = 2. 150

(a + 11d) = [2.1 + (11 × 0.005)] = 2. 155

(a + 12d) = [2.1 + (12 × 0.005)] = 2. 160

(a + 13d) = [2.1 + (13 × 0.005)] = 2. 165

(a + 14d) = [2.1 + (14 × 0.005)] = 2. 170

(a + 15d) = [2.1 + (15 × 0.005)] = 2. 175

(a + 16d) = [2.1 + (16 × 0.005)] = 2. 180

Thus, the rational numbers between 2.1 and 2.2 are 2.105, 2.110, 2.115,

2.120, 2.125, 2.130, 2.135, 2.140, 2.145, 2.150, 2.155, 2.160, 2.165, 2.170, 2.175, 2.180,

Answer» x+1/x=7 → (1) SQUARING both sides x²+1/x²+2=49 x²+1/x²=47 → (2) MULTIPLY (1) and (2) x³+1/x³+1+1/x=329 x³+1/x³+7=329 x³+1/x³=322 Now, (x+1/x)³=x³+1/x³+3(x+1/x) =322+3(7) =322+21 =343

50.

If x+1 upon x is equal to 7 then what will be the value of x+1 upon x whole raised to 3

Answer»

x+1/x=7 → (1)

SQUARING both sides

x²+1/x²+2=49

x²+1/x²=47 → (2)

MULTIPLY (1) and (2)

x³+1/x³+1+1/x=329

x³+1/x³+7=329

x³+1/x³=322

Now,

(x+1/x)³=x³+1/x³+3(x+1/x)

=322+3(7)

=322+21

=343
