let the polynomial x^3 - ax^2 + bx + 6 leave the remainder 3 when divided by x - 3. but it is divisible by x - 2. find the values of a and b. |
|
Answer» Answer: Step-by-step explanation: Let p(x)=x³+ax²+bx+6 i ) it is GIVEN that , (x-2) is a factor of p(x) ,then p(x)=0 => 2³+a(2)²+b×2+6=0 => 8+4a+2b+6=0 => 4a+2b+14=0 Divide each term by 2 , we get => 2a+b+7=0 ---(1) ii)It is given that, if p(x) divided by (x-3) LEAVES a remainder 3 => p(3)=3 => 3³+a(3)²+b×3+6=3 => 27+9a+3b+6-3=0 => 9a+3b+30=0 Divide each term by 3 , we get => 3a+b+10=0 ---(2) SUBTRACT equation (1) from equation (2) , we get a + 3 = 0 => a = -3 Now, Substitute a=-3 in equation (1) , we get 2(-3)+b+7=0 => -6+b+7=0 => b+1=0 => b = -1 Therefore, value of a = -3 & b= -1 |

Angels in a linear pair is supplementary plzzzzzzzzzz guys answer this question |
|
Answer» Step-by-step explanation: A Linear Pair is TWO adjacent angles WHOSE non-common SIDES FORM opposite rays. ∠1 and ∠2 form a linear pair. ... If two angles form a linear pair, the angles are supplementary. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary. is ur ans mate! hope it helped |

Prove that 3+√5 is an irrational |
|
Answer»
Let US assume that 3 + √5 is a rational number. Now, 3 + √5 = (a ÷ B) [Here a and b are co-prime NUMBERS] √5 = [(a ÷ b) - 3] √5 = [(a - 3b) ÷ b] Here, {(a - 3b) ÷ b} is a rational number. But we KNOW that √5 is a irrational number. So, {(a - 3b) ÷ b} is also a irrational number. So, our assumption is wrong. 3 + √5 is a irrational number. Hence, proved. __________________________________ How √5 is a irrational number.? → √5 = a ÷ b [a and b are co-prime numbers] b√5 = a Now, SQUARING on both side we get, 5b² = a² ........(1) b² = a² ÷ 5 Here 5 divide a² and 5 divide a also Now, a = 5c [Here c is any integer] Squaring on both side a² = 25c² 5b² = 25c² [From (1)] b² = 5c² c² = b² ÷ 5 Here 5 divide b² and 5 divide b also → a and b both are co-prime numbers and 5 divide both of them. So, √5 is a irrational number. Hence, proved mark me as BRILLIANT and FOLLOW me |

Satish purchased Sugar Cube having length 3cm. Find value of cube. |
|
Answer» Step-by-step explanation: A cube is a solid BOX whose every surface is a square of same area. Take an empty box with open top in the shape of a cube whose each edge is 2 cm. Now fit cubes of EDGES 1 cm in it. From the figure it is clear that 8 such cubes will fit in it. So the volume of the box will be equal to the volume of 8 unit cubes together. Therefore, the volume of the cube = 8 cu cm Note that 8 = 2 × 2 × 2 Thus, volume of a cube = SIDE × side × side = side3 Hence, a cube has: (i) six SURFACES or faces, (ii) 8 vertices, (iii) 12 edges or sides of equal length. Cube Since a cube has all sides equal. Volume of a cube = (side × side × side) cubic units. = 1 × 1 × 1 cubic units Since area = side × side Volume of a cube = (area × side) cubic units.
