Step-by-step explanation:
Let Jessica's earning be x:
-Given that the total earnings for the three was$228. earnings per person is calculated as:
#Equate their earnings to the 228 to solve for x:
#Substitute for x in each earning equation to determine individual earnings:
Answer:
Here is the full question:
Find the sum of the convergent series by using a well-known function. (Round your answer to four decimal places.) Σ_(n=1)^∞ (-1)^n+1 1/7^n n
Step-by-step explanation:
Σ_(n=1)^∞ (-1)^n+1 1/7^n n
We will use the function In (1 + x)
We will now give a power series expansion of the function while it is centered at x=0
This will give us In (1 + x) = Σ_(n=1)^∞
Note that x= 1/7
Now let us equate the two equations
Σ_(n=1)^∞ = ㏑(1 + x)| = ㏑
Sum of the series will give ㏑
(x – h)^2 + (y – k)^2 = r^2
(h, k) is the center (-4, 0)
r=3
(× + 4)^2 + (y - 0)^2=9
Answer:
y=27
