Answer:

  compounding 6 times per year earns $458.36 more interest over 20 years

Step-by-step explanation:

We can compute the value of the investment for the different compounding schemes. The applicable formula is ...

  A = P(1 +r/n)^(nt)

where P is the principal, r is the annual rate, n is the number of interest periods per year, and t is the number of years.

<u>Compounded 6 times per year</u>:

  A = $3000(1 +.07/6)^(6·20) ≈ $12,067.41

<u>Compounded 1 time per year</u>:

  A = $3000(1.07)^20 ≈ $11,609.05

Use Newton's method to find all solutions of the equation correct to six decimal places. (Enter your answers as a comma-separate
Nata [24]

Answer:

  x ≈ {0.653059729092, 3.75570086464}

Step-by-step explanation:

A graphing calculator can tell you the roots of ...

  f(x) = ln(x) -1/(x -3)

are near 0.653 and 3.756. These values are sufficiently close that Newton's method iteration can find solutions to full calculator precision in a few iterations.

In the attachment, we use g(x) as the iteration function. Since its value is shown even as its argument is being typed, we can start typing with the graphical solution value, then simply copy the digits of the iterated value as they appear. After about 6 or 8 input digits, the output stops changing, so that is our solution.

Rounded to 6 decimal places, the solutions are {0.653060, 3.755701}.

_____

A similar method can be used on a calculator such as the TI-84. One function can be defined a.s f(x) is above. Another can be defined as g(x) is in the attachment, by making use of the calculator's derivative function. After the first g(0.653) value is found, for example, remaining iterations can be g(Ans) until the result stops changing,

71 degrees Determine the value of x.
Bond [772]

Answer:

A) 109 degrees

The answer is 109 degrees because each opposite angle added equals 180°. 180-71= 109

Good luck on your assignment ⊂(◉‿◉)つ
