A fish swims over the waterfall. The distance y (in feet) that the fish falls is given by the function y=16t2 , where t is the t

inessss [21]

Answer:

See Explanation

Step-by-step explanation:

Given

$y = 16t^2$

The equation is incomplete. However, a possible question could be to calculate the distance of the fish at a particular time

e.g. Time, t = 4,

The distance is:

$y = 16t^2$

$y = 16 * 4^2$

$y = 16 * 16$

$y = 256ft$

Another possible question is to determine the time taken to cover a certain distance

e.g.

Distance, y = 400

This gives:

$y = 16t^2$

$400 = 16t^2$

Divide by 16

$25 = t^2$

Take square roots

$5 = t$

$t = 5\ seconds$
