The fox population in a certain region has a continuous growth rate of 6 percent per year. It is estimated that the population i

n the year 2000 was 19100.
(a) Find a function that models the population t years after 2000(t=0 for 2000).
Hint: Use an exponential function with base e.
Your answer is P(t)=

Answer

a)

P(t) = 19100. e^{0.06t}

b) P(8) =30866

Step-by-step explanation

Use formula:

P(t) = P. e^{rt}

a)

Here, P = 19100

r = 6% = 0.06

P(t) = 19100. e^{0.06t}

b) t = 2008 - 2000 = 8

P(8) = 19100. e^{0.06\times 8}

P(8) = 19100. e^{0.48}

P(8) = 19100\times 1.616\\\\P(8) = 30,865.6\\\\P(8) \approx 30,866

1. For what values of x does the function y=2x+13 take on a positive value? a negative value?
egoroff_w [7]
2x+13=0\\
2x=-13\\
x=-6.5

The function is linear where a\ \textgreater \ 0, so it's negative for x\ \textless \ -6.5 and positive for x\ \textgreater \ -6.5

............................

D:x\in\mathbb{R}\setminus\{-1,1,0\}\\\\
\dfrac{a+3}{a^2-1} - \dfrac{1}{a^2+a}=\\
\dfrac{a+3}{(a-1)(a+1)} - \dfrac{1}{a(a+1)}=\\
\dfrac{a(a+3)}{a(a-1)(a+1)} - \dfrac{a-1}{a(a-1)(a+1)}=\\
\dfrac{a^2+3a-a+1}{a(a-1)(a+1)}=\\
\dfrac{a^2+2a+1}{a(a-1)(a+1)}=\\
\dfrac{(a+1)^2}{a(a-1)(a+1)}=\\
\dfrac{a+1}{a(a-1)}


for a\in(-\infty,-1) it's negative
for a\in(-1,0) it's positive
for a\in(0,1) it's negative
for a\in(1,\infty) it's positive

Nora and Lila are reading the same novel for book club. Nora is on page 128 and plans to read 8 pages per day until the next clu
kicyunya [14]

Answer:

- They will be on the same page after 6.5 days or 6\frac{1}{2} days.

- They will be on page 180.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

You know that Nora plans to read 8 pages per day until the next club meeting and she is on page 128.

With this information you can write the following equation of the line in Slope-Intercept form to represent the number of the page "y" she will be on after "x" days:

y=8x+128

Know that Lila is on page 102 and plans to read 12 pages per day until the next club meeting, you can write this linear equation that represent the number of the page "y" she will be on after "x" days:

y=12x+102

Since they will be on the same page after "x" days, make both equations equal and solve for "x":

8x+128=12x+102\\\\26=4x\\\\x=6.5

Substitute that value into any original equation the same page they will be on after 6.5 days (or 6\frac{1}{2} days):

y=12(6.5)+102\\\\y=180
