Scientists on an oceanographic research vessel board a miniature submarine when it is at an elevation of 2 meters above the ocean's surface. the ocean floor directly beneath the boat is at a depth of 180 meters. the submarine descends at a constant rate of 0.4 meters per second. how long, in seconds, could a scientist spend descending after boarding the submarine? a. x < 455 b. x < 450 c. x > 445 d. x > 450

x < 455

Step-by-step explanation:

Given : Submarine is at an elevation of 2 meters above the ocean's surface.

The ocean floor directly beneath the boat is at a depth of 180 meters

The submarine descends at a constant rate of 0.4 meters per second.

To Find : How long, in seconds, could a scientist spend descending after boarding the submarine?

Solution :

Submarine is at an elevation of 2 meters above the ocean's surface

The ocean floor directly beneath the boat is at a depth of 180 meters

So, distance traveled by scientist descending after boarding the submarine = 180 m + 2m = 182 m

The submarine descends at a constant rate of 0.4 meters per second.

So, a scientist spend seconds in descending after boarding the submarine =

So, a scientist spend 455 seconds or less than that descending after boarding the submarine

So, Option A is true

So, x < 455

i belive those are the ones that are under 90 degreese.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
