<h3>Answer: f^{-1}(x) = -6+\sqrt[3]{x}</h3>

======================================================

Explanation:

Replace f(x) with y.

Swap x and y, then solve for y to get the inverse.

f(x) = (x+6)^3\\\\y = (x+6)^3\\\\x = (y+6)^3\\\\\sqrt[3]{x} = y+6\\\\y = -6+\sqrt[3]{x}\\\\f^{-1}(x) = -6+\sqrt[3]{x}\\\\

To solve for y, I first applied the cube root to both sides. Then I subtracted 6 from both sides.

Answer:

  14.1 years

Step-by-step explanation:

Use the compound interest formula and solve for t. Logarithms are involved.

  A = P(1 +r/n)^(nt)

amount when P is invested for t years at annual rate r compounded n times per year.

Using the given values, we have ...

  13060 = 8800(1 +0.028/365)^(365t)

  13060/8800 = (1 +0.028/365)^(365t) . . . . divide by P=8800

Now we take logarithms to make this a linear equation.

  log(13060/8800) = (365t)log(1 +0.028/365)

Dividing by the coefficient of t gives us ...

  t = log(13060/8800)/(365·log(1 +0.028/365)) ≈ 0.171461/0.0121598

  t ≈ 14.1

It would take about 14.1 years for the value to reach $13,060.

A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P (red or blue)
AnnyKZ [126]
The answer is B.

If there are 6 red marbles, 6 white marbles, and 4 blue marbles, then there are 16 marbles total. To find the probability (P) of either the red or blue marbles, you will add together the number of red and blue marbles, and divide that by the total:

(6 + 4) / (6 + 6 + 4)
10/14

This fraction can further reduce to 5/8 (by dividing both the numbers by 2).
