Answer quickly i will mark brainiest and 70 point 3. a scuba diver was exploring a reef 41.36 m below sea level. the diver ascended to the surface at a rate of 7.4 m/min. (a) write an equation to model the situation. use the formula d = rt. (b) why do we write the distance, d, as a positive number? (c) how long did it take the diver to reach the surface? round to the nearest hundredth.

a) You are given the rate as 7.4m/min,

The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.

b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.

c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:

41.36 = 7.4t

To solve for t, divide both sides by 7.4:

t = 41.36 / 7.4

t = 5.59 minutes ( 5 minutes and 35 seconds)

question is incomplete.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
