If the expression -120 + 13m represents a submarine that began at a depth of 120 feet below the sea level an ascended at a rate of 13 feet per minute. What was the depth of the submarine after 6 minutes

42 ft

Step-by-step explanation:

(Negative sign symbolises that the submarine is below the sea level or depth of the submarine.)

Hence, the depth of the submarine after 6 minutes was 42 ft.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
