2. RECUERDA. Encuentra cada una de las expresiones decimales que se piden a partir de la siguiente situación. Marcela prepara una cena, para esta busca en ln- ternet y encuentra que necesita \( \frac{3}{2} \) pollos, \( \frac{1}{4} \) de kilo de papa, \( \frac{2}{3} \) de litro de leche, \( \frac{2}{10} \) de libra de champiñones. Además de otros ingredientes con los que cuenta en la casa; ella qulere solicitar, por medio de una aplicación, un domicilio con los ingredientes pero debe pedir la cantidad de cada uno usando su representación decimal. Para cada ingrediente, Marcela realizá primero una estimación.

Find the zeros of the polynomial function and state the multiplicity of each. \[ f(x)=x^{4}-27 x^{2}+50 \] The smallest zero is -5 with multiplicity 1. (Type an exact answer, using radicals as needed.) The smaller middle zero is \( \square \) with multiplicity \( \square \). (Type an exact answer, using radicals as needed.)

16 For the function \( f(x) \), find the maximum number of real zeros, the maximum number of \( x \)-intercepts, and the maximum number of turning points that the function can have. \( f(x)=x^{5}-x^{4}+9 \)

21. The \( x \)-intercept of the function \( y=-5 x+10 \) is The leading coefficient of the function \( y=9+x^{3}+5 x^{2} \) is . (record in first box) The constant term of the function \( y=-7 x+5+3 x^{2} \) is (record in second box) The degree of the function \( y=7 x^{2}+3-2 x^{3}-6 x \) is (record in the fourd box) (Record your answer in the numerical-response section on the answer sheet.)

Type the correct answer in the box Use numerals instead of words. If necessary, use iffor the fraction bart Jeff needs to buy food and medication for six cals and one dog. The cost of food and medication for a cat is \( \$ 5 \) less than two-thirds of the cost of food and medication for a dog. If Jeff spends a total of \( \$ 195 \), the amount he spent on food and medication for the dog is \( \$ \) Rest
