Verify whether the indicated numbers are zeroes of their corresponding polynomials. (a) Q(s) = -4s^3 + 7s^2 - 24; s = -4 and 1

No, incorrect

Step-by-step explanation:

Given

Q(s) = -4s^3 + 7s^2 - 24; s = -4 and 1

Verifying zeroes

Q(-4) =

-4(-4)^3 + 7(-4)^2 - 24 = 256 + 112 - 24 =344 Incorrect as 344 ≠ 0

Q(1) =

-4(1)^3 + 7(1)^2 - 24 =-12 + 7 - 24 = -29Incorrect as -29 ≠ 0

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
