|
Answer» Answer: b)n zeroes An n degree POLYNOMIAL has at the most n Zero(es).===>> Because when we solve the polynomial EQUATION, we GET at the most n values for the unknown. Hence, the answer is n. Step-by-step explanation: ===>> A polynomial of degree n can have at most n REAL zeros. A polynomialof degree n can have ATMOST n number of zeroes. if n = 2, then the polynomial will have atmost 2 zeroes. |

Question No 6MATHEMATICS][MCQ]QuestionIf the diagonals AC and BD of a trapezium ABCD intersect at o such that DO:OB=1:2 thena) AB=2CD b) CD=2AB C)AC=2BD d) BD=2ACQuestion FileAnswerCAOBOCOD |
|
Answer» Given: ABCD is a trapezium with AB ║ CD. DO : OB = 1 : 2 To Find: RATIO of AB is to CD. Solution: It is given that, AB ║ CD In triangle ABO and triangle CDO ∠ABO = ∠CDO ∵ ( Vertically opposite angles ) ∠DCO = ∠BAO ∵ ( Alternate INTERIOR angles ) => triangle ABO is similar to triangle CDO ∵ ( AA SIMILARITY rule ) => also, DO : OB = 1 : 2 => CD : AB = 1 : 2 => AB = 2 CD Hence, option (a) is correct answer. |

The sides of a triangle are 35 cm, 54 cm and 61 cm respectively. Find thelength of its longest altitude. |
|
Answer» Step-by-step explanation: s= a+b+c
= 2 35+54+61
=75 Area, A= s(s−a)(s−b)(s−c)
= 75(75−35)(75−54)(75−61)
=420 5
cm 2
Now, Area of the TRIANGLE is ALSO given as A= 2 1
×a×h Where, h is the longest altitude. Therefore, 2 1
×a×h=420 5
