Define an equivalence relation p on z as follows: let x, y e z ; xpy if and only if ke z s. t. x - y = 2k show how the reflexive property and symmetric property of equivalence relations hold for p on z.

Answer with Step-by-step explanation:

We are given that an equivalence relation P on Z as

Let

if and only if such that x-y=2k.

We have to show that how the reflexive property and symmetric property of an equivalence relations hold for P on Z.

We know that reflexive property

a is related to a by given relations.

If xPax then we get

Where k=0 and 0 belongs to integers.

Hence, the relation satisfied reflexive property.

Symmetric property :If a is related to b then b is related to b.

If x and y is related by the relation

where k is any integer

k belongs to integers.

Hence, relation satisfied  symmetric property.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

their is no graph showing
