Answer:

B

Step-by-step explanation:

the key says the solid black dots are negative numbers

there is 3 of them

(-3)

the white dots are normal numbers

there are 5

they are being added together

5+(-3)

5-3

2

its B

also, you are so lucky its only 72F where you live I am so hot here it is like 98.

Answer:

<em>P=1620</em>

<em>Third option</em>

Step-by-step explanation:

<u>Horizontal Asymptotes</u>

A given function is said to have a horizontal asymptote in y=a, if:  

\displaystyle \lim _{x\rightarrow -\infty }f(x)=a

Or,

\displaystyle \lim _{x\rightarrow +\infty }f(x)=a

For the given function, the population of the species of bird is given by :

\displaystyle p(t)=\frac{1620}{1+1.15e^{-0.042t}}

Where t is the time in years. To find the horizontal asymptote, we should compute both limits to check if they exist.  

\displaystyle \lim _{x\rightarrow +\infty }\frac{1620}{1+1.15e^{-0.042t}}=\frac{1620}{1+0}=1620

When t tends to plus infinity, P tends to 1620 .

The second asymptote is computed by:

\displaystyle \lim _{x\rightarrow -\infty }\frac{1620}{1+1.15e^{-0.042t}}=\frac{1620}{1+\infty}=0

When t tends to minus infinity, P tends to zero. Since the domain of P is t\geq 0, this asymptote is not valid, thus our only asymptote is

\boxed{P=1620}

the temperature of a city Changed by negative 15 degrees Celsius over a five-week. The temperature change by the same amount eac
Tasya [4]
The really short answer is, there are 5 weeks, and the temperature dropped a total of -15 celsius on those 5 weeks, how many times does 5 go into -15?  -15/5 or -3, so each week, evenly it dropped -3 celsius, and after 5 weeks, it added up to -15 celsius total from the first one.

so in the first week, or week 1, it dropped -3(1), on week 2 it dropped -3(2) on week "w" it dropped -3(w),  f(w) = -3w.
