1. If an arrow is shot straight upward on the moon with a velocity of 78 m/s, its height (in meters) after t seconds is given by .
What is the velocity of the arrow (in m/s) after 7 seconds? 66.38 m/s
After how many seconds will the arrow hit the moon? 94 seconds
With what velocity (in m/s) will the arrow hit the moon? How do you find this?? Is it 78 m/s?
find the values of and that make differentiable everywhere.
Find m=? and b=?
3. Given that
Calculate ( -7)
Both answers for (f*g) and (f/g) are wrong...does anyone know why?
