Olegator [25]

Answer:

(a) 74553

(b) 172120

(c) 234802

Step-by-step explanation:

Given

$y = \frac{340110}{1 + 377e^{-0.259t}}$

Solving (a): 1998

Year 1998 means that:

$t =1998 - 1980$

$t =18$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*18}}$

$y = \frac{340110}{1 + 377e^{-4.662}}$

$y = \frac{340110}{1 + 3.562}$

$y = \frac{340110}{4.562}$

$y = 74553$ --- approximated

Solving (b): 2003

Year 2003 means that:

$t = 2003 - 1980$

$t =23$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*23}}$

$y = \frac{340110}{1 + 377e^{-5.957}}$

$y = \frac{340110}{1 + 0.976}$

$y = \frac{340110}{1.976}$

$y = 172120$ --- approximated

Solving (c): 2006

Year 2006 means that:

$t = 2006 - 1980$

$t =26$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*26}}$

$y = \frac{340110}{1 + 377e^{-6.734}}$

$y = \frac{340110}{1 + 0.4485}$

$y = \frac{340110}{1.4485}$

$y = 234802$ --- approximated

HELP PLEASE: Which is the equation of the graphed line written in

maksim [4K]

Answer:

$x - y = 0$

Step-by-step explanation:

Required

The graph equation

From the graph, we have:

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (1,1)$

The slope of the graph is:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{1-0}{1-0}$

$m = \frac{1}{1}$

$m =1$

So, the graph equation is:

$y = m(x - x_1) + y_1$

$y = 1 * (x - 0) + 0$

$y = 1 * x$

$y = x$

In standard form, we have:

$x - y = 0$
