Scientific notation that's involved with numbers less than one, should always be counted from left to right. Count starting from the decimal until the first number you "jump over". What are you counting exactly?- the number of digits between the decimal and the first 'number' other than zero.
0.0000321 can be also written as 3.21*10^-5 (or 10 with a negative 5 exponent)
Hope this helps.
Answer:
A. 60.5 
Step-by-step explanation:
A = 1/3(area of base)(h)
= 1/3(22)(8.25)
= 60.5
For the given sequence, we can note that:
when we multiply a previous term by 1/4, we get the next term where:
2 * 1/4 = 1/2
1/2 * 1/4 = 1/8
1/8 * 1/4 = 1/32
Therefore, we can say that our sequencer here (r) is equal to 1/4
The general formula to represent this sequence is:
an = a1 * r^(n-1) where :
an represent the nth term that we want to find
a1 represents the first term in the sequence = 2
r is the sequencer = 1/4
n represents the order of the term in the sequence
Based on the above, the equation will be:
an = 2 * (1/4)^(n-1)

Answer: You currently cannot prove this, but people are working on a proof to say it's true
