In the year 2000,there were 8.7 deaths per 1000 reidents in the United States.If there were 281,421,906 residents in the U.S.dur

bekas [8.4K]

$\frac{deaths}{residents} \: \frac{8.7}{1000} \: \frac{x}{281421906}$
Find the "difference" between the residents but division.

281421906/1000 = 281421.906
You always have to do the same to the top
8.7×281421.906 = 2,448,370.5822

There were 2,448,370.5822 deaths

Below is the graph of f ′(x), the derivative of f(x), and has x-intercepts at x = –3, x = 1 and x = 2. There are horizontal tang

guapka [62]

the derivitive is just the slope

minimum happens when the derivitive goes from negative to positive, imagine a slope of the function, the minimum is where the slope goes from neative to positive, and to get there, it has to pass through 0

max happens when the derivitive goes from positive to negative

increaseing is when the derivitive is positive

so, based on what you said, the slope of f(x) is 0 at x=-3, x=1 and x=2 since those are where the derivitive is 0 (derivitive is just the slope)

A and B are wrong because the derivitive isn't 0 at those points

C is correct because increasing means that the derivitive is positive, and so therefo since the only hoirontal place in between 1 and 2 is 1.5, it must remain positive throughout and not dip down, C is right

D is wrong then

answer is C
