The answer it is A i hope is good
Answer:
Explanation:
Duplicate tuples are not allowed in a relation because the specifications of the constraints of the regional integrity are violated, especially the main constraint that states that there can be no identical values for the attributes of two tuples at any database relation state.
Also, duplicate tuples are not allowed in a relation due to the fact that they lead to redundancy of the data base which in turn, slowing down the speed of the database when data processing such as inserting, querying, updating, deleting, etc are being performed.
The points a b c and d lie on a straight line ab:bd = 1:4 are A line that extends to infinity on both sides and has no curves is called a straight line.AB:BC=3:4.
<h3>What do you call a straight line? </h3>
A line is simply an object in geometry denoted as an object with no width that extends on both sides. A straight line is just a line with no curves.
- AC=AB+BC=3+4=7; AC:CD=2:1, i.e. AC=2; because we get 2 different lengths for AC, we change the given ratio AC:CD to an equivalent one with AC=7 .
- As follows: AC:CD = 2 : 1 = 7 : 3.5 (multiply both sides by 3.5 ) Now we have AC:CD = 7 : 3.5 and AD = AC+CD= 7+3.5 = 10.5,, and the answer is: the ratio BC:AD = 4:10.5.
