9. A leatherback sea turtle was swimming at 850 meters below sea level. He went up 165 meters and then descended 165 meters. a. Draw a number line to show the change in position of the sea turtle from the depth it was swimming. b. What integer represents the sea turtle's change in position?

Step-by-step explanation:

Given the following :

Initial Position or depth of leatherback sea turtle = 850m below sea level

He went up 165m and then descended 165m

A.) change in position of the sea turtle from the depth where it was swimming :

B.) Integer to represent tbee sea turtle's change in position :

Change in position : [Distance moved in the upward direction (ascending) - distance moved downward (descending)]

Change in position : (165m - 165m) = 0

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
