(x + 3)^3 = (x + 3)(x + 3)(x + 3) = (x + 3)(x^2 + 6x + 9) = x^3 + 9x^2 + 27x + 27

A girl stands on a carousel and rotated around the ride 6 times if the distance between the girl and the center of the carousel

Lesechka [4]

Answer:

301.74 feet

Step-by-step explanation:

Given:

A girl stands on a carousel and rotated around the ride 6 times.

The distance between the girl and the center of the carousel is 8.

It means radius, r = 8 feet

Question asked:

How many feet did the little girl travel ?

Solution:

As here asked that how many feet the little girl traveled during rotation around the ride 6 times, we will find circumference of the circle.

$Circumference\ of \ circle =2\pi r$

$=2\times\frac{22}{7} \times8\\ =\frac{352}{7} \\ =50.29\ feet$

Now, we will multiply this by 6 as she rotated around the ride 6 times.

$6\times50.29=301.74\ feet$

Thus, the little girl traveled 301.74 feet during this ride.

19. If f(x) = 6x + 3, find f-1(x).

KengaRu [80]

Answer:

$f^{-1}$ (x) = $\frac{x-3}{6}$

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 6x + 3 ( subtract 3 from both sides )

y - 3 = 6x ( divide both sides by 6 )

$\frac{y-3}{6}$ = x

change y back into terms of x, thus

$f^{-1}$ (x) = $\frac{x-3}{6}$
