Answer: 
<u>Step-by-step explanation:</u>
Term-to-term rule is also called the recursive rule.
The recursive rule for a geometric sequence is: 
where
- r is the common ratio
The common ratio (r) is the second term divided by the first term <em>(which is the same ratio for each term divided by its previous term) </em>
In the given sequence {64, 32, 16, 8, 4}, 
So, the recursive rule is: 
Powers of ten, and they're easy to represent as exponents.<span />
Answer:
171.65
Step-by-step explanation:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving forA
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=5·10+5·10+5·10+1
2·﹣54+2·(5·5)2+2·(5·5)2﹣54+2·(5·5)2﹣54≈171.65064
Answer:
Total framed print = 517
Step-by-step explanation:
Framed print:
Small = 23
Medium = 264
Large = 188
Extra large = 42
Total framed print = Small + Medium + Large + extra large
= 23 + 264 + 188 + 42
= 517
Total framed print = 517
Unframed print:
Small = 152
Medium = 544
Large = 496
Extra large = 81
Total unframed print= Small + Medium + Large + extra large
= 152 + 544 + 496 + 81
= 1,273
