The IDENTITY keyword is used to modify a column name, and is used to specify surrogate keys. The first number parameter after IDENTITY specifies the starting value for the surrogate key, and the second number specifies the increment value for each additional record. Thus a column named RelationID and modified by IDENTITY (4000, 5) will be a surrogate key named RelationID with an initial value of 4000 (for the first record in the relation), and with following values incremented by 5: 4000, 4005, 4010, etc.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

no

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
