Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning. Your pie chart must be wrong, because when I added the percentages on your wedges, they totaled \( 124 \% \). A. The statement does not make sense because pie charts are used primarily for relative frequencies, which can add to any total degrees. B. The statement makes sense because pie charts are used primarily for relative frequencies, so the total pie must always represent the total relative frequency of \( 100 \% \). C. The statement makes sense because pie charts are used primarily for relative frequencies, so the total pie must always represent the total relative frequency of \( 360^{\circ} \). D. The statement does not make sense because pie charts are used primarily for relative frequencies, which can add to any total percentage.

Graph the quadratic equation. What is the vertex of the quadratic equation? The vertex is (Simplify your answer. Type an ordered pair.) What is(are) the \( y \)-intercept(s), if they exist? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The \( y \)-intercept(s) is(are) \( \square \). (Simplify your answer. Type an ordered pair, using integers or fractions. Use a comma to separate answers as needed.) B. There are no \( y \)-intercepts.

\( x ^ { 9 } + x ^ { 3 } + 3 x ^ { 2 } = 5 x - 3 \leq 0 \)

Laplace \( \begin{array}{r}f^{\prime \prime}(t)-5 f^{\prime}(t)+6 f(t)=1 \text { where } \\ f(0)=0 \text { and } f^{\prime}(0) \\ =1\end{array} \)

Ao calcular a equação fracionária \( \frac{1}{x}-\frac{1}{x+2}=\frac{x+3}{x(x+2)} \), sendo \( \cup=\mathbb{R} \) - \( \{-2,0\} \), obtém-se:
