A submarine travels 1.2 km due North from its base and then turns and travels due West for 5.8 km. How far away is the submarine from its base? Give your answer rounded to 1 DP.

5.9km

Step-by-step explanation:

this would b solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

1.2² + 5.8² = c²

1.44 + 33.64 = c²

35.08 = c²

c = 5.9 km

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
