1.

the amount of certain principal is 6655rs in 3 years compounded annually at rate of 10 p.c.p.a. find the principal.​

Answer»

<P>ANSWER:

Amount (A) = 6655 RUPEES

Rate (R) = 10 p.c.p.a.

Time (N) = 3 years.

Solution:

\large{ \: A = P × (1 + \frac{r}{100})^{3}}A=P×(1+

100

r

)

3

\large{ \: 6655 = P × (1 + \frac{10}{100})^{3}}6655=P×(1+

100

10

)

3

\large{ \: = P × ( \frac{110}{100})^{3}}=P×(

100

110

)

3

so,

\huge{ \: P = \frac{6655 \times {10}^{3} }{11 \times 11 \times 11}}P=

11×11×11

6655×10

3

\huge{ \: P = 5 \times {10}^{3}}P=5×10

3

\huge{ \: = 5000}=5000

Hence,

The principal was 5000 rupees.

2x-3y=123x+4y =22elemination method​

Answer»

Step-by-step explanation:

2x-3y=12----1

6x-9y=36----(MULTIPLYING THROUGHOUT by 3)----- 2

3x+4y=22-----3

6x+8y=44----(multiplying throughout by 2)----4

subtracting equ4 from equ2

6x-9y=36

- 6x+8y=44

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

-y = -8

y=8

substituting y=8 in equ 1

2x - 3×8 = 12

2x - 24= 12

2x = 12 + 24

2x = 36

x = 36 ÷ 2

x = 18

(18,8) is the solution for the given simultaneous EQUATIONS.

If SinA + CosA = 1/✓2, then find the value of 4SinA.CosA​

Answer»

ANSWER:

LHS= sinA+cosA=1/√2

=(sinA+cosA)²=(1/√2)²

=sin²A+cos²A + 2sinAcosA= 1/2

=2sinAcosA= 1/2-1

=2(2sinAcosA)=(-1/2)2

=4sinAcosA=-1

HENCE THE VALUE OF 4SINA.COSA IS -1.

Find ratio in which the line segment joining the point (-3, 10) and (6, -8) divided by (-1, 6)​

Answer»

ANSWER:

LET the ratio be k : 1 .

Then by the section formula, the coordinates of the point which divides AB in the ratio k : 1 are

[ (-2k+3) / (k+1) , (7k - 3) / (k+1) ]

The point LIES on x-axis, and we know that on the x-axis the ordinate is 0.

Therefore, (7k-3) / (k+1) = 0

=> 7k-3 = 0

=> 7k = 3

=> k = 3/7

=> k : 1 = 3 : 7

Putting the value of k = 3/7, we get point of intersection as

{ [ -2(3/7) + 3] ÷ (3/7)+1 , 0 }

=> { [(-6/7) + 3] ÷ (3/7) + 1 , 0 }

=> [(-6+21)/7 ÷ (3+7)/7 , 0 ]

=> [ 15/7 ÷ 10/7 , 0 ]

=> [ 15/10 , 0 ]

=> ( 3/2 , 0 ).

F(x)=cos(x/x-π) find the point of discontinuity​

Answer»

Answer:

Cosine is a continuous function on R. The functions x → x and x → x - π are continuous on R as well. So, for x ≠ π, x/(x - π) is continuous, which implies the composite F(x) = cos(x/(x - π)) is continuous for x ≠ π.

At x = π, x → x/(x - π) is not defined and, therefore, neither is f. So, the WAY the function f has been defined, it has no points of discontinuity. It is continuous all over its domain R - {π}.  

f, however, doesn't have a LIMIT at π. It KEEPS OSCILLATING from -1 to 1 and doesn't approach any value. So, it' not possible to extend f to the reals (defining it at π) in such a way that it is continuous on the whole R.
