answer:The square root of a negative number is not a real number. Therefore, the equation sqrt{-7 x-3}=9 has no real solutions. Since the sum of two non-real numbers cannot equal a real number, the equation sqrt{3-12 x}+sqrt{-7 x-3}=9 also has no real solutions. There are no real solutions to this equation.

answer:The most significant factor is (B) Trust. Trust is the firm belief in someone's ability, truth, or reliability. In a team setting, trust ensures that members feel safe and comfortable sharing their opinions and ideas during discussions or meetings. Since trust assures members that they will not be judged, they are more likely to contribute their best, leading to improved team success. Additionally, trust increases morale among team members when they realize that their colleagues can count on them, resulting in enhanced individual productivity and, consequently, the overall productivity of the team.

answer:Programming languages are interpreted and executed directly by machines, demanding strict adherence to rules and syntax. In contrast, human languages allow for more flexibility and interpretation, relying on context and human understanding for comprehension.

answer:The cross product of two vectors vec{a} = (a_1, a_2, a_3) and vec{b} = (b_1, b_2, b_3) is defined as: vec{a} times vec{b} = left( begin{array}{c} a_2b_3 - a_3b_2 a_3b_1 - a_1b_3 a_1b_2 - a_2b_1 end{array} right) Plugging in the values of vec{a} and vec{b}, we get: vec{a} times vec{b} = left( begin{array}{c} (9)(-frac{26}{9}) - (frac{65}{9})(-frac{22}{9}) (frac{65}{9})(-frac{85}{9}) - (-frac{47}{9})(-frac{26}{9}) (-frac{47}{9})(-frac{22}{9}) - (9)(-frac{85}{9}) end{array} right) Simplifying each component, we get: vec{a} times vec{b} = left( begin{array}{c} -frac{676}{81} -frac{2249}{27} frac{7919}{81} end{array} right) Therefore, the cross product of vec{a} and vec{b} is left( begin{array}{c} -frac{676}{81} -frac{2249}{27} frac{7919}{81} end{array} right). The answer is vec{a} times vec{b} = left( begin{array}{c} -frac{676}{81} -frac{2249}{27} frac{7919}{81} end{array} right)
