Answer:
6000
Step-by-step explanation:
by observation, we can see that the digit in the thousands place is the number 5. This is the number that we need to either round up or down.
in order to determine if we should round up or down, we need to look at the number which is immediately to the right of this number. If this number is greater than 5, then we round the thousands place up, otherwise it remains the same
In this case, the number immediately to the right (i.e in the hundreds place) is the number 6. This number is greater than the number 5, hence we need to round the number in the thousands (i.e 5) place up to 6, giving us 6000
Answer: 28.4
Step-by-step explanation:
Here we're discussing the "nth partial sum of a geom series."
1 - r^n
The formula for that is s(n) = a(1) ---------------
1-r
We can subst. the given values and see where that takes us:
1 - (-2)^6 1 - 64
105 = a(1)*---------------- = ----------*a(1) = -21*a(1)
1-(-2) 3
105
Solving this for a(1): a(1) = --------- = -5 (answer)
-21
