18. ¿Cuál de las siguientes opciones representa al número \( (888)^{2} \) ? A) \( 2^{6} \cdot 111^{2} \) B) \( 2^{6} \cdot 111 \) C) \( 2^{5} \cdot 111^{2} \) D) \( 2^{5} \cdot 111 \)

a) \( \frac{x+\frac{1}{5}}{0, \hat{3}}=\frac{0,6}{3^{-2}} \)

Using the definition, calculate the derivative of the function. Then find the values of the derivative as specified. \( g(t)=\frac{9}{t^{4}} ; g^{\prime}(-4), g^{\prime}(2), g^{\prime}(\sqrt{5}) \)

Given: \( f(x)=\frac{4}{x-3}+2 \) and \( g(x)=x+2 \) 5.1 Write down the equations of the asymptotes of \( f \)

A survey was conducted on religious practices in the United States. Among other questions, respondents were asked their gender and whether they prayed at least once a day. Of the 19,271 females, \( 66 \% \) said they prayed at least daily and of the 16,285 males, \( 49 \% \) said they prayed at least daily. Use SE = 0.0052. A \( 95 \% \) confidence interval for the difference in the proportion of females who pray at least once a day and the proportion of males who pray at least once a day is \( \pm 1.96(.0052) \).

Clarissa has just completed her second semester in college. She earned a grade of B in her 3 -hour calculus course, a grade of C in her 5 -hour economics course, a grade of B in her 4 -hour engineering course, and a grade of C in her 3 -hour studio art course. Assuming that A equals 4 points, B equals 3 points, C equals 2 points, D equals 1 point, and F is worth no points, determine Clarissa's grade-point average for the semester. Clarissa's grade point average is 2.47 . (Round to two decimal places as needed.)
