Find the vertex of \( y=|x-9|+7 \) \[ \begin{array}{l}\text { a }(6,5) \\ \text { b }(7,3) \\ \text { c }(5,4) \\ \text { d }(9,7)\end{array} \]

Question 4 (4 points) \( \log _{4}(4)=\ldots \ldots \) (round to 3 decimals) Your Answer:

Graph the function. \( f(x)=-\frac{1}{4}(x+5)^{2}+2 \)

2. If \( A=\{a, b\} \), what is \( A \times A \) ? \( ^{*} \) \( \{a, b\} \) \( \{(a, a),(b, b)\} \) \( \{(a, b),(b, a),(a, a)\} \) \( \{(a, a),(b, b),(a, b),(b, a)\} \)

When converting \( 44.644^{\circ} \) to degrees-minutes-seconds what is the minutes? Your Answer:

\( \begin{array}{ll}\text { 기본 예제 } 4 \text { 나머지정리를 활용한 수의 나눗셈 } & \text { 기본 개념 } 012 \\ 05-6 & 15^{4}-3 \times 15^{2}+37 \text { 을 } 13 \text { 으로 나누었을 때의 나머지를 구하시오. }\end{array} \)
