4:11.

1:46.

2:24.

0:59.

3:31.

0:59.

2:03.

ANSWER:

=b1=16+24

=b=40/1

HENCE b=40

ANSWER:

the given equation can be written in the FORM of

now it has EQUAL roots that means The DISCRIMINANT is 0

D = 0

Also

Hence the value of K is 6.

Step-by-step explanation:

Let AB and CD be two PILLARS ,each of HEIGHT hmetres.

Let P be a point on the road such that AP=xm. Then,CP =(150−x)m

In triangle PAB , we have

tan60o=APAB

=3=xh

=3x=h.....................1

In triangle PCD , we have 

tan30o=CPCD

=31=150−xh

=h3=150−x....................2

Eliminating h between eq. 1 and 2, we get

3x=150−x

=x=37.5

Substituting x=37.5 in eq.1 we get ,

h=64.95

Thus the required point is at the distance of 37.5 m from the first pillar and  112.5 m from the SECOND pillar.

The height of the pillars is 64.95 m

ANSWER:

Answer:

SINA + SinB = 2

It means A and B are 90 because SIN90 = 1

sin A = 1/Cos A and Sin b = 1/cos B ACCORDING to trignomatry

1/Cos A + 1/ Cos B = 2

Cos A + Cos B = 2 X Cos A Cos B

Cos A + Cos B = 2 x Cos 90 x Cos 90 = 0 Answer

ANSWER:

Given,

4 FRIENDS A,B,C,D can do work P in 12 days if they all work together, then only A,B,C do work the ratio will be 5:4:3, D will complete 20% of its work, A and B complete P work, C and D complete Q work, then all friends can do another work S(Q+R-15).

Answer,

:- A and B = 12/2 = 6 and 6/2 = 3 then A=3, B=3, THEREFORE A×B = 3×3=9, therefore A and B complete the work P in 9 days [equation 1]

:- C and D = 9 days [ from equation 1]

proof,

Q=9 days,

R=9 days,

therefore,

= Q + R - 15

= 9 + 9 - 15

Here, pluse × minus = minus

= 9 - 9 - 15

= 0 - 15

= 15

ANSWER:

Here the LINE SEGMENT DISTANCE is 2√34 .RATIO is √61:√17.

Answer:

33.33%

Step-by-step explanation:

CP of 16 ARTICLES = SP of 12 articles

CPof 1 ARTICLE = SP of 1 article

CP of 1/16 of article = SP of 1/12 of article

GAIN% = (1/12-1/16)/(1/16) * 100 %

           =(1/48)/(1/16) * 100%

           =100/3% =33.33%

<P>Step-by-step explanation:

As we know, even numbers are always divisible by 2. So if any number is divisible by 2, it is an even number.

Even & odd number come ALTERNATIVELY om number line. So, if 2a is even, 2a + 1 or 2a + any odd number, MUST be odd.

Now, let q = 2a + 1 & p(>q) = 2b + 1.

So,

p + q = 2a + 1 + 2b + 1 = 2(a + b) + 2

p + q = 2(a + b + 1)

As p + q is divisible by 2, it is an even number.

p - q = 2b + 1 - (2a - 1) = 2b + 1 - 2a - 1

p - q = 2(b - a)

p - q = number divisible by 2, it is also an even number. Check your quetion.

(5): As mentioned above ' if any number is divisible by 2, it is an even number.

Even & odd number come alternatively om number line. So, if 2a is even, 2a + 1 or 2a + any odd number, must be odd',

Similarly, 4A is even, 4a + 1 or 4a + any odd number, must be odd.

Thus, 4q + 1 and 4q + 3, both are odd numbers.

Answer:

Given quadratic EQUATION is=x² + 5px +16 = 0

On comparing with standard FORM of quadratic equation i.e ax² + bx + c =0,

Here, a = 1 , b= 5p, c= 16

D(discriminant)= b²-4ac

= (5p)² - 4× 1 × 16

= 25p² - 64

Since, roots of given equation has no real roots.  D < 0.

25p² - 64 <0

5p² - 8² < 0

(5p +8)(5p -8)< 0

[ a² - b² = (a-b)(a+b)]

5p +8 <0 or 5p - 8< 0

k > -8/5 or k < 8/5

-8/5 < k  < 8/5

Hence, the required value of k is -8/5 < k  < 8/5.

Step-by-step explanation:

applydistance FORMULA here

√

so 2^2 = (4-3)^2 + (a-1)^2

4 = 1 + (a-1)^2

3 = (a-1)^2

so a^2 - 2a -2 = 0

so (a-1) (a-2) = 0

so a=1 ,2
