Dennis the Menace is
shooting a rock with his
slingshot with an initial
height of 5 feet. The height,
in feet, of the rock above
the ground is given by
s(t) = -16t+44t + 5,
where t is time in seconds
and t > 0. At what time
will the rock be 15 feet
above the ground?

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

answer: answer: d) v= 1/6 bh
