What is the inverse of the function f(x)=19/x^3 sovle

The inverse of this function would be

In order to find any inverse function, you must start by switching the x and f(x). After you've done that, you must solve for the new f(x). The result will be your inverse function. The work for this one is below.

f(x) = ----> Switch the x and f(x)

x = ----> Cross multiply.

= ----> Take the cube root of both sides

f(x) =

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
