A water fountain jet shoots short spurts of water over a walkway. The water spurts reach a maximum height, then come down into a pond of water on the other side of the walkway. The height above the jet, h, of a spurt of water t seconds after leaving the jet can be found by the function h(t)equalsminus16tsquaredplus16t. Find the time it takes for the spurt of water to return to the jet's height; that is, when h(t)equals0.

The spurt of water takes 1 second to return to the jet's height.

Explanation:

The height above the jet, h, of a spurt of water t seconds after leaving the jet can be given by the function as follows :

.......(1)

We need to find the time it takes for the spurt of water to return to the jet's height i.e. when h(t) = 0

Equation (1) becomes :

So, the spurt of water takes 1 second to return to the jet's height.

The answer is a Complex sentence

Explanation:

Complex sentence is the type of sentence whereby there is atleast an independent clause and one or more dependent clause. since the independent clause can stand alone on its own, it makes it easer to separate from a dependent clause.

From the statement given above, The weather forecast has predicted severe thunderstoms is an independent clause which stood on its own. The dependent clause, the dark, heavy thunderclouds never materialzed is being linked together with an independent clause by a linking work but.
