What is the soloution of x^2-1/x^2+5x+4<_0
1 answer:
<span>You have the following inequality given in the problem shown above:
(x^2-1)/(x^2+5x+4)</span>≤<span>0
1. To solve it, you must factor it and then you must make the study of the signs.
2. Once you do the proccedure mentioned above, you obtain the following solutions:
-4<x<-1
-1<x</span>≤<span>1
3. You can graph the inaquality given in the problem, as you can see in the figure attached.</span>

Answer:
The diver will be in free fall for seconds.
Step-by-step explanation:
The distance in feet, that an object falls in t seconds is given by the function .
Now, given that the height is 4800 feet and we have to calculate the number of seconds the diver was in a free fall.
Therefore,
⇒
⇒ seconds.
Therefore, the diver will be in free fall for seconds. (Answer)
