Ok, so this is a sum of aruthmetic sequence and also use some logic

it goes 10 feet down, then 5 up, 5 down, etc (see attachment)

so the total distance is the sum of all the numbers in the sequence doubled, minus the first term (since it didn't bounce 10 feet up, it started from top)

the sum of an aruthmetic is
Sn=\frac{a_{1}(1-r^n)}{1-r}
where a1=first term, r=common ratio and n=which time

first term=10
common ratio is 0.5
n=4

so
2[\frac{10(1-0.5^4)}{1-0.5}]-10=answer27.5

the answer is 27.5 feet

A printer need to make a poster that will have a total poster area of 200 in^2 and will have 1 inch margins on the sides, a 2-in
Katyanochek1 [597]

Answer:

The dimensions that will give the largest printed area of 132.1669 in^2 are

= Length x Width

= 15.20829 * 8.69045

Step-by-step explanation:

a) Data and Calculations:

Total poster area = 200 in^2

Side margins = 1 inch each

Top and bottom margins = 2 inches each

Let x = length of the full poster

then 200/x = width of the full poster

Therefore, the length of the printed area = x - 3.5

and the width of the printed area = (200/x)-2

Therefore, the Area of the Printed space = (x-3.5)((200/x)-2)

Solving for the Area (A) of the printed space, we have

 

A = (x-3.5)(-200/x2) + ((200/x)-2)

 

A = 700 -2x2

 

If the derivative is set to 0, we have:

0 = 700 -2x2

 

700 = 2x2

 

350 = x2

 

x = 18.70829  The original length

 

width = 10.69045

 

Therefore, the area of space available for printing is

 

15.20829  *  8.69045

 

= 132.1669 in^2
