Give a geometric description of the set of points in space whose coordinates satisfy the given pairs of equations. x squared plus y squared plus left parenthesis z plus 5 right parenthesis squared equals 100, z equals 1 choose the correct description. a. the line through left parenthesis 8 comma 8 comma 1 right parenthesis parallel to the z-axis b. the circle with center (0,0,1) and radius 64, parallel to the xy-plane c. the circle with center (0,0,1) and radius 8, parallel to the xy-plane d. the line through (8,0,1) and (0,8,1)

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
