What is the inverse of the function g(x)=x^3/8+16

shtirl [24]

Answer:

The inverse of the function is $f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}$

Step-by-step explanation:

Inverse of a function:

Suppose we have a function y = g(x). To find the inverse, we exchange the values of x and y, and then isolate y.

In this question:

$y = \frac{x^3}{8} + 16$

Exchanging x and y:

$x = \frac{y^3}{8} + 16$

$\frac{y^3}{8} = x - 16$

$y^3 = \frac{x-16}{8}$

$y = \sqrt[3]{\frac{x-16}{8}}$

The inverse of the function is $f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}$

karie builds a skate ramp with 2 metres of wood. she wants the vertical height of the ramp to be 1 metre. what does the angle el

MA_775_DIABLO [31]

9514 1404 393

Answer:

30°

Step-by-step explanation:

The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:

Sin = Opposite/Hypotenuse

For a ramp 1 m high and 2 m long, we have ...

sin(x) = (1 m)/(2 m) = 1/2

x = arcsin(1/2) = 30°

The elevation angle of the ramp needs to be 30°.
