It's been awhile since I've worked with infinite series and partial sums, but here are my thoughts:
A. the first 4 terms:  -4, - \frac{4}{3}, -\frac{4}{9}, - \frac{4}{27}
B. In examining the partial sums of the series, it appears that the sequence produced has a limit and therefore the series would be convergent.
C. the limit or sum of the series looks to be -5    Below look at the sequence of partial sums:  
-4, -5 \frac{1}{3}, -5 \frac{7}{9}, -5 \frac{25}{27}

So you can see we're getting closer and closer to -5

Which value, to the nearest tenth, is the smallest solution of f(x) = g(x) if f(x) = ln(x + 5) – 1 and g(x) = x3 – 2x + 1?
nekit [7.7K]

Answer:

There are two possibilities of determine which solution is the smallest one:

(i) The smallest solution is the value of x has the smallest distance with respect to origin: (x_{2},y_{2}) = (0.18,0)

(ii) The smallest solution is the most negative value: (x_{1},y_{1}) = (-1.577,0)

Step-by-step explanation:

Let f(x) = g(x), f(x) = \ln (x+5)-1 and g(x) = x^{3}-2\cdot x + 1, then we have the following implicit equation:

\ln (x+5)-x^{3}+2\cdot x -2 = 0 (1)

This equation cannot be solved by analytical means. There are two different strategies to solve this expression: (i) Numerical methods, (ii) Graphical methods. We decide to use the second method:

Let suppose that we use this function h(x) = \ln (x+5) -x^{3}+2\cdot x - 2. By the help of a graphing tool, we find the smallest solution such that h(x) = 0. There are three possible solutions: (x_{1},y_{1}) = (-1.577,0), (x_{2},y_{2}) = (0.18,0), (x_{3}, y_{3}) = (1.376, 0)

There are two possibilities of determine which solution is the smallest one:

(i) The smallest solution is the value of x has the smallest distance with respect to origin: (x_{2},y_{2}) = (0.18,0)

(ii) The smallest solution is the most negative value: (x_{1},y_{1}) = (-1.577,0)

BlackZzzverrR [31]

Answer: y = -1/3x -5 (4th option is correct)

Step-by-step explanation:

  • The slope of a perpendicular line is opposite reciprocal --> -1/3
  • Find b.
  • -4 = -3(-1/3) + b
  • -4 = 1 +b
  • -5 = b

X + 4 5/6 = 9 what is x
dmitriy555 [2]
X+29/6=9
(convert mixed fraction to improper)
x=9-29/6
x=25/6 (calculate the difference)
therefore your answer is x=25/6
or x=4 1/6 OR x= 4.16
