Answer:
810 feet.
Step-by-step explanation:
We are supposed to find the final altitude of the helicopter.
We have been given that a helicopter is flying at a altitude of 785 feet, this means that altitude of helicopter is positive.
Further, the helicopter descends 570 feet, this means that altitude of helicopter is [tex]-570[/tex].
Finally, the helicopter ascends 595 feet, this means that altitude of helicopter is [tex]595[/tex].
[tex]\text{Helicopter's final elevation}=785\text{ ft}-570\text{ ft}+595\text{ ft}[/tex]
[tex]\text{Helicopter's final elevation}=810\text{ ft}[/tex]
Therefore, the final elevation of helicopter is 810 feet.
