find the value of k , if x + 2 is a factor of 5 x to the power 2 + kx + 1 . Please solve this question.. |
|
Answer» Step-by-step explanation: Given - To Find -
As we know that :-
→ p(x) = 5x² + kx + 1 = 0 → p(-2) = 5(-2)² + k(-2) + 1 = 0 → 20 - 2K + 1 = 0 → 2k = 21 → k = 21/2 Hence, The value of k is 21/2 Verification :-→ 5x² + 21x/2 + 1 → 10x² + 21x + 2 → 10x² + 20x + x + 2 → 10x(x + 2) + 1(x + 2) → (10x + 1)(x + 2) Here, the factor comes same as given in the QUESTION. It shows that our ANSWER is absolutely correct. |

Values of how many trigonometric standard angles are lesser than one |
|
Answer» The Trigonometrical RATIOS table will help us to find the values of trigonometric STANDARD angles. The standard angles of trigonometrical ratios are 0°, 30°, 45°, 60° and 90°. The values of trigonometrical ratios of standard angles are very IMPORTANT to solve the trigonometrical problems. Therefore, it is NECESSARY to remember the value of the trigonometrical ratios of these standard angles Step-by-step explanation: I hope its helpful..... |

If the angle of the triangle are equal to three angles of another triangle what about the sides opposite to equal angles |
|
Answer» Step-by-step EXPLANATION: Angles opposite to equal sides of a triangle are equal. Sides opposite to equal angles of a triangle are equal. Each ANGLE of an equilateral triangle is of 60°. If three sides of one triangle are equal to three sides of the other triangle, then the two triangles are congruent (SSS CONGRUENCE Rule). |

Two no.s are in the ratio 2:3 if 5 added to both the no.s the ratio becomes 3:2 find the no.s |
Answer» Given:Two NUMBERS are in the ratio 2:3 if 5 ADDED to both the numbers, the ratio becomes 3:2 Solution :Ratio of the numbers =. 2:3 So, LET the numbers = 2x : 3x When added 5,The numbers = 2x+5 and 3x+5 2x+5 : 3x+5 = 3:2 (2x+5) /3 = (3x+5)/2 2(2x+5) = 3(3x+5) 4x + 10 = 9x + 15 4x = 9x +5 -5x = 5 x = 5/-5 x = -1The numbers = 2x & 3x The numbers = - 2 & - 3Hope this will help... |

Answer» Answer: Q1 NOT CLEAR Q2. Representing fractions on number line shows the intervals between two integers which will help us to increase the basic concept on formation of fractional numbers. 1. Represent the fractions: 2/5, 11/5, -8/5 and -3/5 on a number line. Since, the denominator of each given fraction is 5; divide the space between every pair of two consecutive integers (on the number line) in 5 equal PARTS. Each part so obtained will represent the fraction 1/5 and the number line obtained will be of the form: Representing Fractions on Number Line To mark 2/5; move two parts on the right-side of zero. To mark 11/5; move eleven parts on the right-side of zero. To mark -8/5; move eight parts on the left-side of zero. To mark -3/5; move three parts on the left-side of zero. The following diagram shows markings of fractions 2/5, 11/5, -8/5 and -3/5 on a number line. Fractions on Number Line 2. Represent the following fractions: 1/4, 7/4, -3/4 and -9/4 on a number line. Since, the denominator of each given fraction is 4; divide the space between every pairs of two consecutive integers (on the number line) in 4 equal parts. Each part so obtained will represent the fraction 1/4 and the number line obtained will be of the form: Fractions on the Number Line To mark 1/4; move one part on the right-side of zero. To mark 7/4; move seven parts on the right-side of zero. To mark -3/4; move three parts on the left-side of zero. To mark -9/4; move nine parts on the left-side of zero. The following diagram shows markings of fractions 1/4, 7/4, -3/4 and -9/4 on a number line. Fractions and Number Line 3. Draw a number line to represent fractions: 3/8, 5/8, -1 3/8, -7/8 Since, the denominator of each given fraction is 8; divide the space between every pairs of two consecutive integers (on the number line) in 8 equal parts. Each part so obtained will represent the fraction 1/8 and the number line obtained will be of the form: Fraction Number Line To mark 3/8; move three parts on the right-side of zero. To mark 5/8; move five parts on the right-side of zero. To mark -1 3/8 i.e. -11/8; move eleven parts on the left-side of zero. To mark -7/8; move seven parts on the left-side of zero. The following diagram shows markings of fractions 3/8, 5/8, -1 3/8, -7/8 on a number line. Fractions on a Single Number Line So, in representing fractions on number line we have learnt how to draw any fractional points on the number line. Q3 1. Opposite sides are parallel and congruent. 2. Opposite angles are congruent. 3. Adjacent angles are supplementary. 4. Diagonals bisect each other and each DIAGONAL divides the parallelogram into two congruent triangles. Q4.or = 2x + 4 ot = 3x + 1 or=ot 2x + 4 = 3x + 1 4 - 1 = 3x - 2x 3 = X |

Find two consecutive odd integers such that two fifth of the smaller exceeds two ninth of the greater by 4 |
|
Answer» Answer: Step-by-step explanation: Solution:- Let X be the smaller odd integer and (x + 2) be the greater odd integer respectively. 2/5th of the smaller odd integer EXCEEDS 2/9th of the greater odd integer by 4. So, according to the question. 2x/5 = 2/9*(x + 2) + 4 ⇒ 2x/5 = (2x + 4)/9 + 4 Taking L.C.M. of the denominators of the right side, we get. 2x/5 = (2x + 4 + 36)/9 Now, cross multiplying, we get. ⇒ (2x*9) = 5*(2x + 40) ⇒ 18x = 10x + 200 ⇒ 18x - 10x = 200 ⇒ 8x = 200 ⇒ x = 200/8 ⇒ x = 25 Putting the value of x, we get x + 2 25 + 2 = 27 So, the smaller integer is 25 and the greater odd integer is 27 Answer please mark as a brainliest |

Answer» Answer:(1) 144+145=17² (2)220+221= 21² Step-by-step explanation: 1- Square of 17 = 17 x 17 = 289 Let the number be x (x) + (x+1)= 289 2x + 1 = 289 2x = 289- 1 2x = 288 x = 288/2 =144 Therefore the NUMBERS are, (x) & (x+1)= 144 & 145 Therefore 144+145=17² 2- Square of 21= 21 x 21 = 441 Let the number be x (x) + (x+1)= 441 2x + 1 = 441 2x = 441- 1 2x = 440 x = 440/2 =220 Therefore the numbers are, (x) & (x+1)= 220 & 221 Therefore 220+221= 21² |
