What is pi divided by 2/3?
klasskru [66]
Given:
pi is equal to 3.14

3.14 ÷ 2/3

Rules in dividing fractions.
3.14 is the 1st fraction. It has a denominator of 1. 3.14/1
2/3 is the 2nd fraction

1) get the reciprocal of the 2nd fraction.
2/3 ⇒ 3/2

2) multiply the 1st fraction to the reciprocal of the 2nd fraction
3.14 * 3/2 = (3.14*3) / 2 = 9.42 / 2 = 4.71

Pi divided by 2/3 is 4.71

Find the inverse of f(x)=2x+1
satela [25.4K]

Answer:

h(x) = \frac{x-1}{2}

Step-by-step explanation:

The inverse function is the function which when plugged in to the original one yields the argument (x).

Knowing this we do the following, let h(x) be the inverse function of f:

f(x)=2x+1 \ \ \ \ f(h(x)) = 2(h(x)) + 1 = x\\h(x) = \frac{x-1}{2}\\Now \ we \ verify \ if \ it \ yields \ x.\\f(h(x)) = f(\frac{x-1}{2}) = 2(\frac{x-1}{2}) + 1 = x -1 + 1 = x\\Thus \ h(x) \ is \ the \ inverse\ function \ of \ f
