Answer:

Step-by-step explanation:

sec (-x)-sin (-x) tan (-x)=cos x

sec(x)-(-sin x)(-tan x)=cos x

1/cos x-sin x(sin x/cos x)=cos x

multiply by cos x

1-sin ²x=cos²x

or 1=sin²x+cos²x

which is true.

krek1111 [17]

Answer:

The region with the highest population density is Binky Lee

The region with the lowest population density is Cheslen

Step-by-step explanation:

we know that

The <u><em>population density</em></u> is the number of people per unit of area

so

Find out the population density for each region

<em>Bear Creek</em>

\frac{462}{112}= 3.70\ people/acre

<em>Binky Lee</em>

\frac{12,624}{3,412}= 4.13\ people/acre

<em>Cheslen</em>

\frac{3,537}{1,263}= 2.80\ people/acre

<em>Crow's Nest</em>

\frac{2,142}{612}= 3.5\ people/acre

so

Cheslen < Crow's Nest < Bear Creek < Binky Lee

therefore

The region with the highest population density is Binky Lee

The region with the lowest population density is Cheslen
