please solve the problems in the pictures, thank you!!!

\f\f\f\f\f\f\f\f(1 point) Is the graph of y = sin(x6) increasing or decreasing when x = 9'? (enter increasing, decreasing, or neither). Is it concave up or concave down? (enter up, down, or neither). \f\f(1 point) Find the derivative of the function y), below. It may be to your advantage to simplify before differentiating. f0) = arctano) f'U) = (1 point) Find the derivative of the function r(t), below. It may be to your advantage to simplify before differentiating. r(t) = arcsin(3t) r'(t) = \f\f(1 point) Find the slope of the tangent to the curve x2 + 4):)? + y2 = 46 at (1, 5). The slope is (Enter undef if the slope is not dened at this point.) \f\f
