The question is written unclear.
my guess would be 24:7 (24/7)
Greetings!
When reflecting a shape over the x-axis, you simply change the number to its opposite positive/negative equivalent.
This means that the new co-ordinates would be (-5,1) , (-5,4) and (-2,4).
Hope this helps!
The answer is 11.13 so in nearest tenth it would be 11.1
Final Velocity = Initial Velocity + (Acceleration * time)
Final Velocity = ?
Initial Velocity = 3
Acceleration = 1.5
Time = 7
Plug in and solve
3+(1.5*7)
3+10.5
Velocity = 13.5m/s
