Answer:

a) rational

b) irrational

Step-by-step explanation:

a) 36 = 6²

So sqrt(36) = 6

b) 72 = 2 × 36

sqrt(72) = sqrt(2) × sqrt(36)

Since 2 is not a perfect square, sqrt(72) is irrational

What is the value of the expression

Levart [38]

Answer:

$\boxed{\sf -2}$

Step-by-step explanation:

$\sf Evaluate \: - {x}^{2} - 4x - 6 \: where \: x = - 2: \\ \sf \implies - {x}^{2} - 4x - 6 = - {( - 2)}^{2} - 4( - 2) - 6 \\ \\ \sf {( - 2)}^{2} = 4 : \\ \sf \implies - \boxed{ \sf 4} - 4( - 2) - 6 \\ \\ \sf - 4( - 2) = 8 : \\ \sf \implies - 4 + \boxed{ \sf 8} - 6 \\ \\ \sf - 4 + 8 - 6 = 8 - (4 + 6) : \\ \sf \implies 8 - (4 + 6) \\ \\ \sf 4 + 6 = 10 : \\ \sf \implies 8 - \boxed{ \sf 10} \\ \\ \sf \implies - 2$

Equations to find the inverse of f(x) = y = 3x/8+z

kicyunya [14]

To find the inverse of the the function, it must be arranged in such a way that the independent variable be on the left side and the dependent variable on the right. So,f(x) = y = 3x/ (8 + x)y (8 + x) = 3x8y + xy = 3x8y = 3x - xy8y = x (3 - y)8y / (3-y) = xx = 8y / (3 -y)
Therefore,f-(x) = f(y) = x = 8y/ (3 - y)
