In the first one divide -3 by both sides and when you get an answer plug it back in for x to check and got second one multiple bu four on both sides and you will get an answer. And put that answer on the graph.

The population of the small town of Parks in 2000 was estimated to be 3,901 people with an annual rate of decrease of about 1.8%

trasher [3.6K]

Answer-

The estimated population in 2013 is 3081.

Solution-

This can be represented as exponential decreasing function,

$y=a(1 - r)^t$

Where,

a = starting amount
r = rate
t = years

Putting the values,

$y=3901(1 - 0.018)^{13}$

$=3901(0.982)^{13}$

$=3901\times 0.7897$

$=3080.62$

As population can not be in fraction, so after rounding off the estimated population in 2013 is 3081.

The equation f(x) = 3x2 − 24x + 8 represents a parabola. What is the vertex of the parabola?

s2008m [1.1K]

$\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ f(x)=\stackrel{\stackrel{a}{\downarrow }}{3}x^2\stackrel{\stackrel{b}{\downarrow }}{-24}x\stackrel{\stackrel{c}{\downarrow }}{+8} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right) \\\\\\ \left(-\cfrac{-24}{2(3)}~~,~~8-\cfrac{(-24)^2}{4(3)} \right)\implies (4~~,~~8-48)\implies (4~~,~-40)$
