Answer:
25m/s
Step-by-step explanation:
1000/4=25
(4, 15)
let (x,y) is the mid point of line segment with endpoints (2,14) and (6,19)
we have,
x = (2+6)/2 = 4
y = (14+16)/2 = 15
Hence the midpoint of the line segment with endpoints (2,14), (6,19) is (4,15)
to multiply-----
(2y-1)(2y+1)
2y(2y+1)-1(2y+1)
4y^2+2y-2y-1
=4y^2-1
