Answer:
D. 1.2
Step-by-step explanation:
The sum of an arithmetic sequence is the product of the average term value and the number of terms.
The average term is often computed by averaging the first and last terms of the sequence. It can also be computed by averaging the middle two terms of the sequence (when there are an even number of terms, as here).
We are given a_13 is 1.9. We know that a_12 is 3.7 less, so is -1.8. Then the average of these two middle terms is ...
... (-1.8 + 1.9)/2 = 0.05
The product of this value and the number of terms (24) is ...
... 24·0.05 = 1.2 . . . . . the sum of 24 terms of the sequence
the sales tax is close to 217.94
It
can be described useing two other undefined terms :- point & line
Answer:
B
Step-by-step explanation:
The formula for volume of cylinder is given below:
volume of cylinder = 
Where r is the radius (here, it is given as 3)
h is the height, the perpendicular distance from base to top (here, it is 4 NOT 5 since 5 is the 'slant height')
Plugging in the available info , we get our answer:
B is the correct answer
