A girl drops a ball off a cliff into the ocean. The polynomial −8t2+350 gives the height, in feet, of the ball t seconds after it is dropped from a 350ft tall cliff. Find the height, in feet, after t=2 seconds.

318 feet.

Step-by-step explanation:

We have been given that a girl drops a ball off a cliff into the ocean. The polynomial gives the height, in feet, of the ball t seconds after it is dropped from a 350 ft tall cliff. We are asked to find the height in feet after 2 seconds.

To find the height after 2 seconds, we will substitute in our given equation as:

Therefore, the height will be 318 feet after 2 seconds.

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
