Answer:
Option 1
Step-by-step explanation:
Given expression representing the partial sum of the geometric series,
Expression that represents the sum of a geometric series is,
Here, n = number of terms
a = first term
r = common ratio
By comparing both the expressions,
n = 4
a = 125
r =
From the given options,
Option 1
First term 'a' = 125
Common ratio 'r' = =
Number of terms 'n' = 4
Therefore, Option 1 will be the correct option.
Answer:
r = - 13 / 15 inches/week
Step-by-step explanation:
The numerator is 13
and the denominator is 15, then we have
r = - 13 / 15 inches/week
r < 0 since the water level of the lake fell
Because you are not adding the x's .When you add the coefficients, the variable comes along with it.
Answer:
The formula is Lenght * width * height = 12*6*5= 360 in^2
