Can someone help and explain how to answer this step by step so that I know how to do it? I don't know if I did the first part right. The figure shows the depths of a submarine.

a. Find the vertical distance traveled by the submarine. Write your answer as a decimal.
The vertical distance is -410.7 feet.
Work: -725.6 - -314.9 = -410.7 (-410.7 is negative because both decimals are the same signs)
b. Find the mean hourly vertical distance traveled by the submarine. Write your answer as a decimal.
The mean hourly distance is _ feet per hour.

the answer is b

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
