Ivory makes $18 a day babysitting. which expression would you use to find how much ivory earns if she works 20 days in 6 months?
c) 20x 6
the answer is c.
very easy question.
i'm assuming it's looking for the missing length, which should be 4cm
hope this !
option 4 : 16+24i
given a circle has a diameter with end points at(15+25i) and (-25-17i)
centre would be the mid point of these two points
out of given four points to find which point lies on the circle
if a point lies on the circle then it would have distance from centre equal to radius.
radius = distance between two given points/2
let us calculate distance form each point.
i)-15+2i: distance from -5+4i= 10.19
ii) 0+0i : distance from -5+4i = 6.40
iii) 15+17i : distance from -5+4i = 23.85
iv) 16+24i: distance from -5+4i= 29
hence only 4th point lies on the circle
