Question

A scuba diver descends slowly into the ocean at a constant rate. His depth is recorded for the first minutes in the following table:
a) how much deeper does the diver descend each minute?

b) what is the diver’s depth at minute 7?

c) how long will it take the scuba diver to reach a coral reef that is 120 feet deep?

d) Interpret the meaning of d8 = 96

Answer 1

Answer:

a) 12 feet per minute

b) 84 feet

c) 10 minutes

d)

Step-by-step explanation:

a) find the slope using furmula: y1 - y2/x1 - x2

24 - 12/2 - 1

12/1

12

12 feet per minute

b) 12 feet per minute so multiply the slope, 12 by 7

12 * 7 = 84

c) 12 * time, t, = feet deep

12 * t = 120

12t = 120

/12 /12

t = 10

10 minutes
