Question 1054883: please help me.
A stone is thrown upward with a horizontal velocity of 80 ft./s and an upward velocity of 60 ft./s. At t seconds it will have a horizontal displacement H equal to 80t and a vertical displacement V equal to 60t – 16t2. The straight-line distance S from the stone to the launch point is found by the Pythagorean theorem. Write an equation for S in terms of t, and simplify.

A stone is thrown upward with a horizontal velocity of 80 ft./s and an upward velocity of 60 ft./s.
At t seconds it will have a horizontal displacement H equal to 80t and a vertical displacement V equal to 60t – 16t2.
The straight-line distance S from the stone to the launch point is found by the Pythagorean theorem.
Write an equation for S in terms of t, and simplify.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

S = sqrt%28+%2880t%29%5E2+%2B+%2860t+-+16t%5E2%29%5E2+%29  - this is an equation (an equality) expressing S via t.


You may simplify it.
