The object reaches its maximum height when velocity is equal to zero, the velocity is the derivative of function height. That is:
(1)
Where 
is the velocity of the object at time 
, in feet per seconds.
If we know that 
and 
, then the time when object reaches its highest point is:
The object will reach its highest point 0.5 seconds after it has been thrown.
Adding what rational expressions?
3/30 or 1/10 or $3
There all the same answer just different ways
The first one is unsimplified The second one is simplified The last one is in money form
$4/3=$1.33 per pound.
$9/8 = $1.13 per pound.
