Hi friendshow are you all plzz give me the answer genius 1.consider a polynomial f(x)=ax3+bx2+x+2/3 .if x+3 is a factor of f(x)ans if f(x)is divided by x+22,then we get reminder as 5.then, find the value of a andbis urdent plzz give me the answer

Answer»

ANSWER:

Step-by-step EXPLANATION:

F(x) = ax3 + BX2 + x +2/3

F(- 3) = -27A + 9B – 3 + 2/3 = 9a+3b+1=0

So, 9a+3b+1=0……(i)

F(-22) = -10648a+484b-22+2/3

So, 31944a +1452 b – 64 = 0 ……..(ii)

 From (i) and (ii), we get

      a = -137/9075 , b = -2614/9075

the edges of a triangular board are 6cm 8cm and 10cm the cost of painting it at the rate70 paise per centimetre square​

Answer»

Step-by-step EXPLANATION:

s=sum of edges/2 so s=12

s= HALF of perimeter

12×(12-6)×(12-8)×(12-10)=576

square ROOT of 576 = 24

so the area of board is 24cm²

now multiply 24×70=1680

COST of PAINTING is 1680 paise = 16.8 rs

A takes 3 hrs more than B to walk a distance of 30 km. but if A doubles his speed he is ahead of B by 1.5 hrs . Find the speed of A and B​

Answer»

Answer:

A's SPEED 10km/3hr B's speed 5km/hr

Step-by-step explanation:

let B's speed be xkm/hr and A's speed be ykm/hr than time TAKEN by B is 30/x

so time TAKE by A is (30/x)+3

now we have

30/y = (30/x)+3 ( 1st equation)

in second condition when A's doubles his speed the equation is 30/2y = (30/x)-1.5 (2ND equation)

SOLVING this we get A's speed y=10km/3hr and B's speed x 5 km/hr

A man gave 50% of his savings of.84100 to his wife anddivided the remaining sum among his two sons A and B of15 and 13 yr of age respectively. He divided it in such away that each of his sons when they attain the age of18 yr, would receive the same amount at 5% compoundinterest per annum. The share of B was..::.:....​

Answer»

Answer:

20000

Step-by-step explanation:

84100/2 = 42050

A's SHARE = (42050-X)

and B's share = x

now (42050-x)×21³/20³ = x × 21⁵/20⁵

(42050-x) = x × 21²/20²

(42050×20²-x ×20²) = x ×21²

42050×20² = 841x

x = 42050×20²/841

x= 20000

Pls answer 12 question ​

Answer»

GIVEN

2( {a}^{2}  +  {b}^{2} ) =  {(a + b)}^{2}

SIMPLIFICATION

2( {a}^{2}  +  {b}^{2} ) =  {(a + b)}^{2}  \\  \\  \\  \implies 2 {a}^{2}  + 2 {b}^{2}  =  {a}^{2}  +  {b}^{2}  + 2ab \\  \\  \\  \implies 2 {a}^{2}  +  {2b }^{2}  -  {a}^{2}  -  {b}^{2}  = 2ab \\  \\  \\  \implies  {a }^{2}  +  {b}^{2}  - 2ab = 0 \\  \\  \\  \implies  {(a - b)}^{2}  = 0 \\  \\  \\  \implies a - b = 0 \\  \\  \\  \implies \:  \boxed{a = b} \:  \: (proved)

THEREFORE OPTION (B) is CORRECT .

IDENTITIES USED

(a+b)^2 = a^2 + b^2 + 2ab

(a-b)^2 = a^2 + b^2 - 2ab
