Question 5 Solve \( r^{4}-41 r^{2}+400=0 \) List them separated by commas, for example: \( \frac{2}{3}, \frac{5}{2}, \sqrt{5},-\sqrt{5} \) type \( 2 / 3,5 / 2 \), sqrt(5),-sqrt(5) \( \rightarrow \) Next Question ?

Convert this mixed number to an improper fraction. \( \quad 1 \frac{3}{4} \)

Expand and simplify an expression for the area of this rectangle. \[ \text { area }=\square \]

Multiply. \( (\sqrt{-4})(\sqrt{-25}) \) \( (\sqrt{-4})(\sqrt{-25})=\square \) (Simplify your answer.)

6 Suppose \( f(x)=9-\sqrt{x} \) and \( g(x)=x^{2}+4 \). a Find \( (f \circ g)(x) \) and state its domain and range. \( \quad \) b Find \( (g \circ f)(4) \). c Find \( (f \circ f)(x) \) and state its domain and range.
