Answer: First Option : Sₙ= n/2(a₁ + aₙ)
Step-by-step explanation:
The nth partial sum of an arithmetic sequence or the sum of the first n terms of the arithmetic series can be defined as the sum of a finite number of term in an arithmetic sequence.
It is calculated using the formula:
Sₙ= n/2(a₁ + aₙ)
Where :
a₁ = First term
aₙ = last term
n = number of terms
Total cost = 0.95 x $150 + $5.50 = $142.50 + $5.50 = $148
Okay, I can exactly show my work. but you can answer this by counting the muber of spaces between points A and C. So the answer should be A 13, my bud.
If you graph these points you can easily see that the slope is 1 and the y-intercept is -3. Therefore y=x-3.
(3.14 hours) x (60 min/hr) x (60 sec/min) = <em>11,304 sec</em>
