Answer:
see explanation
Step-by-step explanation:
(1)
Note the ratio of consecutive terms is common, that is
2000 ÷ 2500 = 0.8
1600 ÷ 2000 = 0.8
1280 ÷ 1600 = 0.8
This indicates that the series is geometric with common ratio r = 0.8
The sum to n terms of a geometric series is
= 
← a is the first term
Here a = 2500 and r = 0.8, thus
= 
= 
= 8404
(2)
Note the difference in consecutive terms is common, that is
3 - 11 = - 8
- 5 - 3 = - 8
- 13 - (- 5) = - 8
This indicates that the series is arithmetic with common difference d = - 8
The sum to n terms of an arithmetic series is
= a₁ + (n - 1)d ← a₁ is the first term
Here a₁ = 11 and d = - 8, thus
= 11 + (13 × - 8) = 11 - 104 = - 93
Answer:
14-16x=32-10x
14-6x=32
-6x=18
x=-3
hope this helps
have a good day :)
Step-by-step explanation:
Keep in mind that means is the same as asking for the average. all you need to do is add all the values and divide them by the number of values, which is 5
<span>$39.99 + $31.99 + $19.99 +$23.99 + $26.99= 142.95
mean= 142.95/5 = 28.59</span>
Answer:
If then
Step-by-step explanation:
If a syllogism is a kind of logical arguement then it applies to deductive reasoning to arrive at a conclusion based on two or more propositions
The translation is (x-8,y+5). To get from A to A’ you go left (x-axis) 8 times and up (y-axis) 5 times.
