The first relation indicates the bars each drinker visits, the second tells what beers each bar serves, and the last indicates which beer each drinker likes to drink. Express the following queries in relational algebra. If joins are needed, indicate what the condition of the join is: (1) Find the bars that serve a beer that drinker Smith likes. (2) Find the bars that serve all beers that drinker Smith likes.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

you first to choose the points and then move from then as the slope you have

its very big question plz make it small
