The altitude (in feet) of an object in motion, d, after t seconds is given by the equation:
d = –16t2 + vt +h
where v is the initial velocity and h is the initial
height
A catapult launches a stone with an initial velocity of
48 feet per second and an initial height of O feet.
How long will the stone be in flight?
seconds

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

english, cause i can’t you

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
