2.) Rita Reads a book at a steady pace. Rita graphs her progress through the book by putting the time in hours "t" on the horizontal axis and chapters remaining "C" on the vertical axis. Which equation describes Rita's graph? *v

Explanation:

The figure of the graph is missing: find it in attachment.

The two variables involved here are:

- Along the x axis (independent variable), the time "t", in hours

- Along the y axis (dependent variable), the remaining chapters "c"

The relationship between the two variables is linear and so it can be written in the following form:

(0)

where

m is the slope of the line

q is the y-intercept

The y-intercept is the value of y when x = 0; here, it is the value of c when

t =0.

From the graph we see that this is

c = 24

So

q = 24 (1)

The slope can be found by evaluating the ratio

for 2 points along the line.

Taking the following points:

(0,24)

(8,0)

We find:

(2)

So, we can rewrite (0) using (1) and (2):

which means

Population growth is one way

It me to understand the world and my place in it. for example, (and i know i’m using the terminology ‘historical perspective’ loosely here; some of my examples may be better termed an ‘evolutionary perspective’) knowing that all humans can trace their ancestry back to a common ancestor who lived in southern ethiopia ~200,000 years ago makes me feel connected to everyone on the planet. knowing that some of our ancestors left africa about 70,000 years ago and interbred with more archaic hominin species in europe and elsewhere, me to see the stupidity of white supremacist ‘purity of the race’ themes. seeing how religion was used to enslave people, and how callously lives were thrown away by those in power in the world wars of the past century makes me feel extremely fortunate to be living in the modern era. and, perhaps most importantly is that this knowledge makes me for the sacrifices our ancestors made to get us to this point, and determined to do my part to make the world a better place for the next generation.
