Solution:
we are given that
The federal budget for 2007 was 2.8 trillion dollars.
we have been asked to find
how much money did the government spend per second?
First we will find the number of seconds in one year
Number of seconds in 1 year
Seconds
Now we will dive the amount by the total number of seconds, we get
Hence the government is spending approximately 88787 dollars per second.
U have a geometric sequence. To find the common ratio, divide the second term by the first term. 6/12 = 1/2
an = a1 * r^(n-1)
n = term to find = 10
a1 = first term = 12
r = common ratio = 1/2
now we sub
a(10) = 12 * 1/2(10 - 1)
a(10) = 12 * 1/2^9
a(10) = 12 * 1/512
a(10) = 12/512 reduces to 3/128 ,<== ur 10th term
Based on the picture she could use wood screen screws to make something similar
