A. \( y=9-x^{2} ;(2,5) \)

Find the set \( A \cap B \). \( \begin{array}{l}U=\{1,2,3,4,5,6,7,8,9\} \\ A=\{1,2,3,7\} \\ B=\{1,2,6\}\end{array} \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. \( A \cap B=\{\square\} \) (Use a comma to separate answers as needed.) B. \( \mathrm{A} \cap \mathrm{B} \) is the empty set.

ii \( \quad 160.27 \div 0.0235 \)

Use the column method to work out \( 34.3-11.1 \)

4) \( 6^{0}+5 .(20-6.3)^{4} \) 1) \( .28 \sqrt{10.4+4}+2^{5} \)
