1.	Form a quadratic polynomial whose product and sun of zeros are -1/4 and under root 3
Answer» Answer:Let alpha and BETA are the zeroes of the POLYNOMIAL. Sum of zeroes = (Alpha + Beta) = -8/3 And, Product of zeroes = (Alpha × Beta) = 4/3 Therefore, Required QUADRATIC polynomial = X²-(Alpha + Beta)X + Alpha × Beta => X²-(-8/3) X + 4/3 => X²+8X/3 + 4/3 => 3X²+8X+4/3 = 0 => 3X²+8X+4 = 0 × 3 => 3X²+8X+4 = 0 Hence, The Quadratic polynomial is 3X²+8X+4 HOPE IT WILL HELP YOU....... :-)

1.

Form a quadratic polynomial whose product and sun of zeros are -1/4 and under root 3

Answer»

Answer:Let alpha and BETA are the zeroes of the POLYNOMIAL.

Sum of zeroes = (Alpha + Beta) = -8/3

And,

Product of zeroes = (Alpha × Beta) = 4/3

Therefore,

Required QUADRATIC polynomial = X²-(Alpha + Beta)X + Alpha × Beta

=> X²-(-8/3) X + 4/3

=> X²+8X/3 + 4/3

=> 3X²+8X+4/3 = 0

=> 3X²+8X+4 = 0 × 3

=> 3X²+8X+4 = 0

Hence,

The Quadratic polynomial is 3X²+8X+4

27.

Gun power contains 75% nitre 15% charcoal and the rest sulphur. find the the amount of sulphur in in 9 kilogram of gunpowder.plz answer with explanation..

Answer»

Step-by-step explanation:

The amount of gunpowder =8 kg=8000 g ....[WKT 1 kg=1000 g]

Quantity of NITRE in gunpowder =75% of 8000 g

=(75/100)×(8000)

=(75×80)

=6000 g=6 kg

Quantity of SULPHUR in gunpowder =10% of 8000 g

=(10/100)×8000

=(10×80)

=800 g=0.8 kg

The quantity of CHARCOAL in gunpowder =[8000−(6000+800)]

=[8000−6800]

=1200 g

=1.2 kg

∴ the quantity of charcoal in 8 kg of gunpowder is 1.2 kg

37.	A boy having a mass of 60 kg holds in hands a school bag of weight 40 N . With what force the floor will push up on his feet? plz answer with steps.yrr ya free points nhi hai samjha dimag na kaharab karo....Don't spam
Answer» Step-by-step explanation: So we know that the boy weighs 60kg therefore the force that he's applying to the FLOOR is 60g N (with g being the value attributed to the gravity in N). The boy with the bag that he’s holding then apply a force to the GROUND that measures 60g + 30 N. If there are no other forces applied , and the boy is standing still then the reaction exerted by the ground is the same as the force applied by the boy with the bag as these are two directly opposite forces. “For every ACTION, there is an EQUAL and opposite reaction” => \|\|R\|\| = 60g + 30 N hope it helped you!!!

43.	The first four terms of an AP whose first term is -2 and the common difference is -2 are(a) -2,0, 2,4 (b)-2,-4, -8, -16 (c) -2,-4,-6,-8(d) -2,-4,-8,-16
Answer» Answer: OPTION (C) : -2,-4,-6,-8 Step-by-step explanation: a = -2 d = -2 formula of GENERAL TERM of AP : a(n) = a + (n-1)d a(1) = -2 a(2) = -2 + (2-1)(-2) = -2-2 = -4 a(3) = -2 + (3-1)(-2) = -2 + 2(-2) = -2-4 = -6 a(4) = -2 + (4-1)(-2) = -2 +3(-2) = -2-6 = -8 ALTERNATE METHOD : d = a(n+1) - a(n) >>> a(n+1) = a(n) + d since we are given with the first term and the general difference, terms can be found by putting n = 1,2,3 as well

The first four terms of an AP whose first term is -2 and the common difference is -2 are(a) -2,0, 2,4 (b)-2,-4, -8, -16 (c) -2,-4,-6,-8(d) -2,-4,-8,-16

Answer»

Answer:

OPTION (C) : -2,-4,-6,-8

Step-by-step explanation:

a = -2

d = -2

formula of GENERAL TERM of AP : a(n) = a + (n-1)d

a(1) = -2

a(2) = -2 + (2-1)(-2) = -2-2 = -4

a(3) = -2 + (3-1)(-2) = -2 + 2(-2) = -2-4 = -6

a(4) = -2 + (4-1)(-2) = -2 +3(-2) = -2-6 = -8

ALTERNATE METHOD :

d = a(n+1) - a(n) >>> a(n+1) = a(n) + d

since we are given with the first term and the general difference, terms can be found by putting n = 1,2,3 as well
