Express the given sets in notations: the set consisting of the elements 0, -1, -4, -3?

{ 0, -1, -4, -3}

{ x : x ∈ Z, -4 ≤ x ≤ 0, x ≠ - 2}

Step-by-step explanation:

Set is the collection of well defined objects and the object of set are called elements,

There are two types of notation of a set,

Tabular form : listing the elements of a set, separated by commas and enclosed within curly brackets '{}'

Set builder form : Writing in symbolic form the common characteristics shared by all the elements of the set,

Thus, by the above statements,

The notations of a set having elements 0, -1, -4, -3 is,

{ -4, -3, -1, 0}

Or

{ x : x∈Z s.t -4 ≤ x ≤ 0, x≠ - 2}

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
