Hey there!
1.21 repeating as a fraction is 40/33.
Hope this was of help, have a great day :)
Answer:
Yes
Step-by-step explanation:
ab = ba when a = 2 and b = 3
(2)(3) = (3)(2)
6 = 6
Best of Luck!
It's 5 because when you ask a question, the answer is always 5.
Using an=a1rn−1, what is the 10th term in this geometric sequence? 0.2, 1, 5, 25, 125, ... f 1,953,125 g 9,765,625 h 390,625 j 7
RSB [31]
Use the formula a(n) = a(1)*r^(n-1), where r is the common factor and n is the counter.
The first term, a(1), of <span>0.2, 1, 5, 25, 125, ... is obviously 0.2. Note that multiplying 0.2 by 5 gives us 1; mult. 5 by 5 gives us 25, etc., so the common factor r is 5.
Thus, a(n) = a(1)*r^(n-1) becomes a(n) = 0.2*(5)^(n-1), and
a(10) = 0.2*(5)^(10-1), or 0.2*5^9, or 0.2(1953125), or 390625 (answer)</span>
