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
Calculate 6
Calculate -8
Calculate ( -7)
Calculate (-1/7)
Both answers for (f*g) and (f/g) are wrong...does anyone know why?
velocity is the derivative of position ...With what velocity (in m/s) will the arrow hit the moon? How do you find this?? Is it 78 m/s?
function needs to be continuous ...2. If
find the values of and that make differentiable everywhere.
Find m=? and b=?
f(10) = 100 , so 100 = m(10) + b
to be differentiable ...
f'(10) = 20, so 20 = m ... b = -100
product rule ...Both answers for (f*g) and (f/g) are wrong...does anyone know why?
quotient rule ...
