Let
x-------> the length side of the poster
y-------> the width side of the poster
we know that
Area of the poster is equal to
-------> equation 
Area of the printed area is equal to
----> equation 
substitute equation
in equation

using a graph tool
Find the vertex of the graph
The vertex of the graph is the point that represent the value of x for the largest printed area
see the attached figure
the vertex is the point 
the largest printed area is 

find the value of y

therefore
the answer is
The dimensions of the poster are 
Traci will be 360 miles in 12 hours if the linear equation y = 30x describes how far from home Traci is as she drives from Dallas to Anchorage and the equation of the graph is linear.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have a linear equation:
y = 30x
Here, x represent the number of hours and y represent the number of miles.
When x = 12 hours then
y = 30(12) = 360 miles
If draw the graph the equation y = 30x, it will be a linear equation.
(refer attached picture)
Thus, Traci will be 360 miles in 12 hours if the linear equation y = 30x describes how far from home Traci is as she drives from Dallas to Anchorage and the equation of the graph is linear.

Answer:
$2431
Step-by-step explanation:
First we need to find the area
A = l*w
A = 13*17
A =221 ft^2
It cost 11 dollars per square foot so multiply the price times the number of square ft
221*11 =2431
The total cost will be 2431
This is a Poisson Distribution
Average over 3 months = 2
Average over 1 month = 2/3
Average over 2 months = 4/3 = λ
More than four heavy rainfalls means 5, 6, 7,…
P(5) = (e^-λ x λ^5)/5! = 0.009257
P(6) = 0.002057
P(7) = 0.000392
P(8) = 0.000065
P(9) = 0.000010
P(10) = 0.000001
P(more than 4 heavy storms) = 0.01178 (4sf)
