Convert 320 degrees to radians Convert \( \frac{25 \pi}{18} \) to degrees radians Give a exact answers, using pi for \( \pi \) if needed

7. The graph of \( f(x)=80 \cdot(0.5)^{x} \) is shown. Tasha believes that the graph touches the \( x \)-axis while Greg believes that it doesn't. Who is correct, and how do you know?

Evaluate the function. If the value is not a rational number, round your answer to three decimal places. (a) \( \operatorname{csch}^{-1}(3) \) (b) \( \operatorname{coth}^{-1}(6) \)

Evaluate the function. If the value is not a rational number, round your answer to three decimal places. (a) \( \operatorname{csch}(\ln (4)) \) (b) \( \operatorname{coth}(\ln (6)) \)

Find any vertical asymptotes. \( h(x)=\frac{(x-3)(x+6)}{x^{2}-4} \)

Find the vertical asymptotes, if any, and the values of \( x \) corresponding to holes, if any, of the graph of the rational function. \( h(x)=\frac{x+3}{x(x-2)} \) A. The vertical asymptote(s) is(are) \( \square \) and hole(s) corresponding to \( \square \) a comma to separate answers as needed.) B. The vertical asymptote(s) is(are) \( \square \). There are no holes. C. There are no vertical asymptotes but there is(are) hole(s) corresponding to \( \square \). D. There are no discontinuities.
