Controlling the time TCS foods are exposed to unsafe temperatures helps limit the growth of bacteria. I Figure 1.1 from the textbook as a guide to select the food item from each of the following groups that ru ime and temperature control to keep it safe. \( \begin{array}{ll}\text { A. baked chicken } & \text { A. whole tomatoes } \\ \text { B. canned beans } & \text { B. precut fresh tomatoes } \\ \text { C. beef jerky } & \text { C. canned tomatoes }\end{array} \)

4. Determine el límite de la función vectorial dada cuando su variable tiende a 2 . \[ r(x)=\left(\frac{x-2}{x^{3}-8}\right) i+\left(\frac{x^{2}-4}{x^{2}-5 x+16}\right) j+\left(\frac{2 x-4}{x^{2}-6 x+18}\right) k \]

Solve the equation by the square root property. \( 2 x^{2}+7=17 \) The solution set is \( \{ \). (Simplify your answer. Type an exact answer, using radicals as needed. Use a comma to separate answers as needed.)

\( \left. \begin{array} { l } { 7 \times 8 = 7 \times ( \_ + } \\ { 7 \times 8 = ( 7 \times \quad ) + ( 7 \times \quad ) } \end{array} \right. \)

2. Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs \( \frac{3}{4} \) pound, a navel orange that weighs \( \frac{5}{8} \) pound, and a pear that weighs 0.5 pound. What is the order of the fruit from least weight to greatest weight?

Simplify: \( \left(3^{2}\right)^{2} \). Leave your answer in exponent notation and do not change the base.
