The elevation of an underwater cave is -120 feet relative to sea level. a submarine descends to the cave. the submarine rate of change in elevation is no greater than -12 ft per sec. how long will it take to reach the cave

Time taken by the submarine to reach the cave is 10 seconds.

Step-by-step explanation:

We are given that,

The elevation of the underwater cave = -120 feet.

The rate at which the submarine descends to the cave = -12 feet per second

Thus, we have,

The time taken by the submarine to reach the cave = = 10 seconds.

Hence, the time taken by the submarine to reach the cave is 10 seconds.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
