Step-by-step explanation:
<u>Recursive Sequences</u>
The recursive sequence can be identified because each term is given as a function of one or more of the previous terms. Being n an integer greater than 1, then:
f(n) = 2f(n-1)+1
f(1) = 4
To find the first four terms of the sequence, we set n to the values {2,3,4,5}
f(2) = 2f(1)+1
Since f(1)=4:
f(2) = 2*4+1
f(2) = 9
f(3) = 2f(2)+1
Since f(2)=9:
f(3) = 2*9+1
f(3) = 19
f(4) = 2f(3)+1
Since f(3)=19:
f(4) = 2*19+1
f(4) = 39
f(5) = 2f(4)+1
Since f(4)=39:
f(5) = 2*39+1
f(5) = 79

. This ratio can be also written as the following fraction:
The television shows an image with a ratio of 
which can be also written as a fraction:
Set up the following proportion and solve for "x":
Now, in order to find the percent of the screen area occupied make the following division:
Answer:
4.5 cm.
Step-by-step explanation:
The volume of the pyramid = 1/3 * area of the base * height.
Area of the triangle = 1/2 * base * height
= 1/2 * 14 * 8
= 56 cm^2.
So the volume of the pyramid =
84 = 1/3 * 56 * h
h = 84 / (1/3 * 56)
h = 84 * 3 / 56
= 4.5 cm.
