Answer:
Domain constraints include entity integrity and referential integrity and this domain is a set of values that may be assigned to an attribute. The entity integrity rule states that no part of a primary key cannot be null. Referential integrity states that each foreign key value must match a primary key value or be null
Each table has certain set of columns and each column allows a same type of data, based on its data type. The column does not accept values of any other data type.
Step-by-step explanation:
Domain constraints include entity integrity and referential integrity and this domain is a set of values that may be assigned to an attribute.
The ENTITY INTEGRITY rule states that no part of a primary key cannot be null while the REFERENTIAL INTEGRITY rule states that each foreign key value must match a primary key value or be null.
Each table has certain set of columns and each column allows a same type of data, based on its data type in which the column does not accept values of any other data type.
Therefore Domain constraints are user defined data type and can define in this way:
Domain Constraint = data type + Constraints (NOT NULL / UNIQUE / PRIMARY KEY / FOREIGN KEY / CHECK / DEFAULT)
Answer:
the answer is 81,592 cuz you have to multiple
Answer:
Step-by-step explanation:
Given
Perpendicular to 
Required
Determine the line equation
An equation has the form
Where
By comparison with
Because the line is perpendicular to , the following relationship exists
i.e. the condition for perpendicularity
Where m1 is the slope of the equation that passes through
So, we have:
The line equation is then calculated using:
Where
So, we have:
Add 11 to both sides

<em>Apply the same steps used in (a) above and you'll get your answers</em>
This is perhaps the most odd math question I have ever come across. Anyhow -
#1 - Positive, because smoking increases the chance of having lung cancer. (though technically there is not a linear relationship between the two as people do in fact receive lung cancer even when having not smoked)
#2 - No relationship. (Though one could argue a student may text more when given more free time as a consequence of having spent less time at school, but this is wholly subjective and unable to be substantiated by logic.)
#3 - Negative, due to the mass of the tootsie pop decreasing with each lick.
Of course, I am assuming when you say "positive" and "negative" you are speaking in terms of numbers or addition and subtraction rather than "positive" or "negative" socially.
