For this case we assume that the photo album is rectangular in shape and therefore the fabric too. By definition, the area of a rectangle is given by:

Where:
a: It is the length of the rectangle
b: It is the width of the rectangle
According to the problem data we have to:

Substituting:

We clear "a":

Thus, the length of the fabric is 
ANswer:
The length of the fabric is
Answer:
f(x)=5cos(1/3x) this is an equation
Answer:
first
Step-by-step explanation:
f(n) =56 (0.5)^(n-1)
f(1) = 56 (0.5)^0= 56*1 = 56
f(2) =56 (0.5)^1 = 56* 0.5 = 28
f(3) = 56 (0.5)^2 = 14
f(4) = 56 (0.5)^3 = 7
Answer:
nth term = (1/6)(6)^(n-1).
Step-by-step explanation:
The first term a1 = 1/6 and the common ratio r = 1 / 1/6 = 6, also 36/6 = 6 which confirms this.
So the nth term = a1 r^(n - 1)
= (1/6) 6^(n-1).
