(- 1 + √3)/2

rationalise the denominator by multiplying the numerator/denominator by the conjugate of the denominator.

the conjugate of 1 + √3 is 1 - √3

(1 - √3)/(1 + √3)(1 - √3) = (1 - √3)/( 1² - (√3)²) = (1 - √3)/(1 - 3) = (1 - √3)/(- 2)

multiply numerator/denominator by (- 1)

Luba_88 [7]

a) For 900 units of currency X, at an exchange rate of y = 1.05x, you could get <u>945 of currency Y.</u>

b) The inverse function is x is <u>0.9524y</u> and it represents the conversion of units of currency Y to units of currency X.

c) For 46 units of currency Y, at the exchange rate of x = 0.9524y, you could get <u>43.81 of currency X</u>.

<h3>What is an exchange rate?</h3>

An exchange rate is a value that a currency has with another.

The exchange rate shows the proportion or ratio at which two currencies are exchanged.

<h3>Data and Calculations:</h3>

The exchange rate of X (x) to Y 9y) is y = 1.05x.

For 900 units of currency X, you could get 945 of currency Y (1.05 x 900)

The inverse function is x = 0.9524y (900/945)y

For 46 units of currency Y, you could get = 43.81 of currency X (0.9524 x 46).
