November 6, 2024 at 8:54AM Solve the problem on a separate sheet of paper and submit the work to Grgdescope. SHOW ALL WORK using MatLab. 1. An experiment was conducted by having a group of children solve a puzzle. It was found that of those who had solved the puzzle on a given trial, 30\% could solve it on the next trial. And of those who couldn't solve the puzzle on a given trial, \( 60 \% \) could solve it on the next trail. At the present time, 80\% of the children solved the puzzle on the current trial, but 20\% did not. Assume that this process can be modeled as a Markov process. - Write the transition matrix. Label the columns and rows, using S for "able to solve" and NS for "not able to solve. - Write the initial distribution matrix. - What percent of the children will be able to solve the puzzle on the next trial (trial 1)? - What percent of the children will be able to solve the puzzle on trial 2? - After many trials, what percent of the children will fail to solve the puzzle on each trial?

La función exponencial con base "e" aparece en muchos contextos científicos porque modela procesos naturales. Veamos por qué: A. En matemáticas el número "e" es un número irracional infinito y de gran relevancia en los números reales. B. La función \( f(x)=e^{\mathrm{X}} \) modela crecimiento y decrecimiento en fenómenos como la población o la radiactividad, etc. C. La función exponencial con base el número "e" es conocida función exponencial natural por modelar diversos fenómenos naturales. D. La función \( f(x)=e^{X} \) toma valores bastante complejos y coinciden con mínimos comportamientos naturales y por ello su aplicación.

\( \begin{array}{ll}\text { g) }\end{array} f(x)=\log (x+2) \quad \) en \( x=-2 \quad \) h) \( \quad f(x)=\frac{x-9}{\sqrt{x}-3} \quad \) en \( \quad x=9 \)

Solve the equation algebraically, and then use a calculator to find the values on the interval \( [0,2 \pi) \), \[ \tan ^{2}(x)+5 \tan (x)-5=0 \] \( x=\square \)
