let A = R .suppose R is the relation on A DEFINED by aRb if and only if a &gt;= b . Determine if R is a partial order.
liberstina [14]

Answer:

R is a partial order

Step-by-step explanation:

The relation is reflexive

That is to say, aRa

a\geq a \; \forall a \in \mathbb{R}

The relation is antisymmetric, if aRb and bRa, then a=b

(a\geq b)\land (b\geq a) \Rightarrow a=b

The relation is transitive, if aRb and bRc, then aRc

(a\geq b)\land (b\geq c) \Rightarrow a \geq c

Answer:

The answer is

<h2>21.45 g/cm³</h2>

Step-by-step explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of platinum = 214.5 g

volume = 10 cm³

It's density is

density =  \frac{214.5}{10}  \\

We have the final answer as

<h3>21.45 g/cm³</h3>

Hope this helps you
