Which inequality correctly compares One-third, Five-sixths, and Three-fifths? One-third < Three-fifths < Five-sixths One-t

lilavasa [31]

Answer:

$\frac{1}{3} \: < \: \frac{3}{5} \: < \: \frac{5}{6}$

Step-by-step explanation:

We want to compare the fractions

$\frac{1}{3}, \frac{5}{6} , \frac{3}{5}$

First, we collect LCM

The LCM of 3,6, and 5 is 30

$\frac{1}{3} = \frac{10}{30} , \\ \frac{5}{6} = \frac{25}{30} , \\ \frac{3}{5} = \frac{18}{30}$

$\frac{10}{30} , \frac{18}{30} , \frac{25}{30}$

This means that

$\frac{1}{3} , \frac{3}{5} , \frac{5}{6}$

Hence,

$\frac{1}{3} \: < \: \frac{3}{5} \: < \: \frac{5}{6}$

Using the given zero, find one other zero of f(x). i is a zero of f(x).= x4 - 2x3 + 38x2 - 2x + 37.

oksian1 [2.3K]

If i is a zero of the polynomial, then the factor is (x - i). Because of the conjugate rule, it is understood that one other root of the polynomial HAS to be (x + i). So that's one other root. The other 2 roots are (1 + 6i) and (1 - 6i).

The answers are marked in the attached image. The associative property of addition states that we can group numbers in any order we want as long as we're adding them. The same applies for the associative property of multiplication.

A similar rule is the commutative property of multiplication which says we can multiply numbers in any order. Example: 2*3 is the same as 3*2. Addition works this way as well. Example: 5+7 is the same as 7+5
