The formula for working out speed :
speed = distance ÷ time.
substitute the numbers : 100m ÷ 10.92s.
give your answer in meters per second ( m/s )
the answer I got while working this out was:
9.2 m/s.
Answer:
this is a negative slope
Step-by-step explanation:
hope this helps!
Answer:
m=3 and m=-3
Step-by-step explanation:
m^2 = 9
m = square root of 9
Since a positive or negative number squared produce a positive value, the answer is either positive or negative.
When we reflect a point across y=x, the x and y coordinates switch out , that is (x,y) becomes (y,x) . SO for point (1,2), on reflection across y=x, (1,2) becomes (2,1) . And when we do reflection across y=-x, (x,y) becomes (-y,-x). Therefore point (2,1) on reflection across y=-x becomes(-1,-2) .
So the final answer is (-1,-2) .
