Identify the degree and the leading coefficient of the graph. => odd and positive or even and positive or odd and negative or even and negative..

Which of the following polynomial functions has leading coefficient 3, degree 3 and - 1, 3 and 5 as real zeros? => f ( x ) = 3 x 3 - 21 x 2 + 21 x + 45 or f ( x ) = 3 3 - 21 x 2 + 2 x - 2 or f ( x ) = 3 3 - 21 x 2 - 21 x - 45 or f ( x ) = 3 x 3 - 21 x 2 + 21 x - 25..

Select the polynomial function with leading coefficient 4, degree 4, and zeros - 3, - 1, 0 and 5 2 . => f ( x ) = 4 x 4 + 6 x 3 + 28 x 2 + 30 x or f ( x ) = 4 x 4 + 6 x 3 - 28 x 2 - 60 x or f ( x ) = 4 x 4 + 6 x 3 + 28 or f ( x ) =..

(The values given below should be treated as approximate, as they vary with different specimens of the same material) SI. No Substance Yong’s modulus (Y) 10 11 dyne cm -2 or 10 10 N m -2 Bulk modulus (K) 10 11 dyne cm -2 or 10 10 N m -2 Rigidity modulus..

An equation of the form ax 2 +bx+c=0 where a, b, c are real numbers and where "a" does not equal to zero(0). The sum of the roots of a quadratic equation is equal to the negation of the coefficient of the second term divided by the leading coefficient. The pro..

The persistence of audible sound even after the source has ceased emitting sound is called reverberation. If the reverberation of a sound pulse persists so long as to prolong the sound while several successive pulses are produced, the intelligibility will suffer, leading to poor acousti..

Ordinary glass is a mixture of sodium and calcium silicates and is made by heating a mixture of sand (essentially SiO 2 ) with sodium carbonate and calcium oxide in a furnace at around 1700K and cooling rapidl..

. For a sparingly soluble ionic salt of the type AB 2 the dissolution leads to the equilibrium where mp + = nq - . The solubility product constant for th..

The above discussion leads to find the solution of a system of linear equations in two variables by using Cramer's rule. Cramer's rule suggests the use of determinants to solve a system of linear equations. Let us denote a 1 b 2 - a 2 b 1 (Denominators of x and y in (4) and (5)) as the de..
