Answer:
D
Step-by-step explanation:
the n th term ( explicit formula ) of a geometric sequence is
•
= 

where r is the common ratio and
the first term
here r =
=
=
and
= 64, hence
= 64
→ D
Answer:
<h2> <em><u>384</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Dimensions of the rectangular prism = 9ft, 12ft and 4ft
<em><u>Therefore</u></em><em><u>, </u></em>
Surface area of the rectangular prism
= 2( lb + bh + lh)




<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Surface</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>rectangular</u></em><em><u> </u></em><em><u>prism</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>384</u></em><em><u> </u></em><em><u>sq</u></em><em><u>.</u></em><em><u> </u></em><em><u>ft</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Given expression : 12.3 + 6 (n - 0.5)
Step 1 : substitute n = 3.7
12.3 + 6 (3.7 - 0.5)
Step 2 : Simplify the parenthesis
12.3 + 6 (3.2 )
Step 3 : Do the multiplication and open the parenthesis
12.3 + 19.2
Step 4 : Add the two number
12.3 + 19.2 = 31.5
So the answer of the given expression when n = 3.7 is 31.5
