3/x=36
Multiply both sides by x
3=36x
Then divide both sides by 36
3/36=x
1/12=x
Final answer: 1/12
Answer:
a. Geometric
b. 20, 10 and 5
c. Tn = 20(0.5)^n-1
d. 0.00004 ft
Step-by-step explanation:
a. The sequence is geometric
The reason for this is that we will be multiplying each term by a particular value
If it was arithmetic, we would have been adding instead. But since it is geometric, we shall multiply terms by a particular number
b. 1st term is
20
second term
1/2 * 20 = 10
Third term
1/2 * 10 = 5
c. Explicit formula
Mathematically, that will be;
Tn = ar^n-1
Where r is 1/2 or 0.5
Tn = a(0.5)^n-1
where Tn is the present term and n is the present number of the term
d. 20th term
T20 = 20 * 0.5^19
T20 = 0.00004 ft
Different cultures used different calendars to measure time and year. In this modern era we measure year according to the Gregorian calendar, so our current year is 2015. Now according to the Chinese calendar, they use the Lunisolar calendar to measure year, so right now it the year 4712 in china.
