A submarine is only allowed to change its depth be Racing toward the surface in 60 meter stages. If the submarine starts off at

lara31 [8.8K]

Answer:

$Depth = 100m$

Step-by-step explanation:

Given

Initial Level = 340 m

Number of stages = 4

Difference in each stage = 60 m

Required

Determine the depth of the submarine after 4 stages

First, we have to calculate the total distance moved towards the surface of the sea;

This is calculated as

$Total\ Distance = Number\ of\ Stages * Difference\ in\ each\ stage$

$Total\ Distance = 4 * 60m$

$Total\ Distance = 240m$

This implies that the submarine moved a total distance of 240 metres;

It;'s new depth is calculated as follows;

$Depth = Initial\ Depth - Total\ Distance$

$Depth = 340m - 240m$

$Depth = 100m$

Hence, its new depth after 4 stages of rising is 100m

Can someone explain HOW to simplify this algebraic fraction, as in tell me why and what I need to do for each step : 1-n/n^2-1

Andreyy89

- I’m assuming the expression implies the following:

(1-n)/(n^2 - 1)

The steps goes as follows:

= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)

At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.

= -1/(n+1) , which is the answer

Note: You could also see it as 1/-(n+1) or 1/(-n-1)
