Because of the rules for sequence of operations, multiplication is done before addition or subtraction.
3-(3*6)+2
= 3-18+2
=-13
The distance from the initial depth to the maximum depth is:
abs (-200- (-25))= 175 m (distance is always >=0, so we have to take the abs).
175 m* (1 sec/ 2.5m)= 70 sec.
It would take the submarine 70 seconds to reach its maximum depth.
Hope this helps~

Answer:6.66666666667
Step-by-step explanation:
The radius is the distance from the center to any point. The distance from (2,1) to (0,1) is of course 2. The general formula for a circle with radius r and center (a,b) is

In our case we get
