4.	-5 is one of the zeros of 2x²+px-15 , zeros of p(x²+x)+k are equal to each other . Find the value of k
Answer» ong>GIVEN :- -5 is one of the zeroes of POLYNOMIAL 2x² + px - 15. Zeroes of p(x² + x) + k are equal. TO FIND :- Value of 'k'. SOLUTION :- Part 1 :- -5 is one of the zeroes of 2x² + px - 15. So, for x= -5 , 2x² + px - 15 = 0 → 2(-5)² + p(-5) - 15 = 0 → 2(25) - 5P - 15 = 0 → 50 - 5p - 15 = 0 → 35 - 5p = 0 → 5p = 35 → p = 35/5 → p = 7 Hence , value of p is 7. Part 2 :- Zeroes of [ p(x² + x) + k ] are equal. Putting value of p, [ 7(x² + x) + k ] [ 7x² + 7X + k ] is the required equation. For equal zeroes , discriminant = 0. ★ D = (b² - 4ac) = 0 Here , a → Coefficient of x². b → Coefficient of x. c → Constant. We have , a = 7 b = 7 c = k Putting values, → 7² - 4(7)(k) = 0 → 49 - 28k = 0 → 28k = 49 → k = 49/28 → k = 7/4 Hence , value of k is 7/4.

-5 is one of the zeros of 2x²+px-15 , zeros of p(x²+x)+k are equal to each other . Find the value of k

Answer»

ong>GIVEN :-

-5 is one of the zeroes of POLYNOMIAL 2x² + px - 15.
Zeroes of p(x² + x) + k are equal.

TO FIND :-

Value of 'k'.

SOLUTION :-

Part 1 :-

-5 is one of the zeroes of 2x² + px - 15.

So, for x= -5 , 2x² + px - 15 = 0

→ 2(-5)² + p(-5) - 15 = 0

→ 2(25) - 5P - 15 = 0

→ 50 - 5p - 15 = 0

→ 35 - 5p = 0

→ 5p = 35

→ p = 35/5

→ p = 7

Hence , value of p is 7.

Part 2 :-

Zeroes of [ p(x² + x) + k ] are equal.

Putting value of p,

[ 7(x² + x) + k ]

[ 7x² + 7X + k ] is the required equation.

For equal zeroes , discriminant = 0.

★ D = (b² - 4ac) = 0

Here ,

a → Coefficient of x².
b → Coefficient of x.
c → Constant.

We have ,

a = 7
b = 7
c = k

Putting values,

→ 7² - 4(7)(k) = 0

→ 49 - 28k = 0

→ 28k = 49

→ k = 49/28

→ k = 7/4

Hence , value of k is 7/4.

16.

The compound interest on a certain some of money at 5% per annum for two years is 246. Calculate the S.I on the same sum for threeyears at 6% per annum.

Answer»

ong>ANSWER:

SI=432

Step-by-step EXPLANATION:

CI=246, R=5%, T=2 years

Let the PRINCIPAL be x

A=P(1+R/100)^T

A=x(1+5/100)^2

A=x×21/20×21/20=441/400x

We have CI=A-P

246=441/400x-x

246=441-400/400

246=41/400

x=246×400/41= 2400 rupees

Now, given rate=6%

Time=3years

SI=P×R×T/100

SI=2400×6×3/100

SI=432 rupees

7. The salary of an employee is increased by 20%. By what percentage should the new salary be reduse to restore the original salary?

Answer»

Taking the sample value to be 100.

A 20% INCREASE means 100*1.2=120.

Thus a total increase of 20.

Now let's FIND the RATIO of 20 to 120 i.e., 20/120=0.1666.

Changing to percentage 0.1666*100=16.6%.

Hence, a decrease of 16.6% to the new salary will restore the original salary.
