Which of the following pairs of functions are inverses of each other?
Serggg [28]

Answer:

<em>The answer is (B).</em>

Step-by-step explanation:

A). y = f(x) = 6(x - 2) + 3 ⇔ y = 6x - 12 + 3 ⇔ 6x = y + 9 ⇔ x = \frac{y+9}{6}

g(x) = \frac{x+9}{6} is inverse function of f(x) and ≠ \frac{x+2}{6} - 3

<em>B).</em> y = f(x) = \frac{5x}{4} - 3 ⇔ 4y = 5x - 12 ⇔ x = \frac{4y+12}{5}  

g(x) = \frac{4(x + 3)}{5} is inverse of f(x)

The length of a rectangle is 5 less than twice the width. If the perimeter of the rectangle is 146 cm, find the dimensions of th
Marta_Voda [28]

Length = 2x - 5

Width = x

Perimeter = 146

P = 2L + 2W

146 = 2(2x - 5) + 2x

146 = 4x - 10 + 2x

146 = 6x - 10

146 + 10 = 6x

156 = 6x

156/6 = x

26 = x

Length = 2(26) - 5

Length = 52 - 5

Length = 47 cm

Width = x

Width = 26 cm

2032 base four expanded notation
BabaBlast [244]
Assuming 2032 is itself a number in base 4, you have

2032_4=2\times4^3+3\times4^1+2\times4^0

Or, if you mean to ask about converting 2032 into base 4, you have

\dfrac{2032}4=508 with remainder 0, which means the "ones" digit is 0.
\dfrac{508}4=127 with remainder 0, which means the "tens" digit is also 0.
\dfrac{127}4=31 with remainder 3, so the "hundreds" digit is 3.
\dfrac{31}4=7 with remainder 3, so the "thousands" digit is also 3.
\dfrac74=1 with remainder 3, so the next digit is also 3.
\dfrac14=0 with remainder 1, so the next (and final) digit is 1.

So, 2032_{10}=133300_4.
