Let f\left(x\right)=\frac{2}{x}f ( x ) = 2 x and g\left(x\right)=\frac{x}{x-1}g ( x ) = x x − 1. Find the domain of \left(\frac{

Black_prince [1.1K]

Answer:

The domain is (-∞,0) ∪ (0,1) ∪ (1, +∞)

Step-by-step explanation:

In order to be able to compute f/g (x), we need that x is on the domain of f and in the domain of g.

f(x) = 2/x

In order to be able to compute f(x), we need that the denominator is different from 0, hence x≠0.

g(x) = x/x-1

In order to be able to compute g(x). we need x-1 to be different from 0, thus x≠1.

We also need the denominator of f/g (x) to be different from 0, hence g(x) ≠ 0. In order for g(x) = x/x-1 to be 0, the numerator x should be 0, as a result, we need x≠0 in order to have g(x) ≠ 0.

The domain of f/g (x) is every real nummber besides 0 and 1, in other words, it is (-∞,0) ∪ (0,1) ∪ (1, +∞).

This is not a right triangle as 2.6 squared plus 8.1 squared does not equal 8.6 squared (Pythagorean theorem)

If you bought a car five years ago for $15,000 and today you can sell for $7000 what was its rate of depreciation

Natalka [10]

<h2>Answer:</h2><h2>The rate of depreciation of the car is 14%</h2>

Step-by-step explanation:

The price of car purchased 5 years ago = 15000

The price of car sold = 7000

By compound depreciation,

$Pn = P (1 - R/100) ^ T$ ... (1)

where Pn = 7000

P = 15000

R = rate of interest to be calculated

T = 5 ( number of years)

substituting the values in equation (1), we get

$7000 = 15000 (1 - R/100) ^ 5$

$0.46 = (1 - R/100) ^ 5$

$0.858 = 1 - R/100$

0.858 is rounded off as 0.86

R/100 = 0.14

By simplifying the above equation, we get

Rate of depreciation = 14%
