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?

2.If

find the values of and that make differentiable everywhere.

Find m=? and b=?

3.Given that

Calculate6

Calculate-8

Calculate (-7)

Calculate(-1/7)

Both answers for (f*g) and (f/g) are wrong...does anyone know why?
