Which exponential function models a geometric sequence with initial value a and a common ratio of 0.7? 1 O f(n) = a(0.7) f(n) = a(0.7)" 1 O f(n= a + (0.7)" O f(n) = a + (0.7)" 1 1

Find the gradient of f(x,y,z)equals=left parenthesis x squared plus y squared plus z squared right parenthesis superscript negative 1 divided by 2 baseline plus ln left parenthesis x right parenthesis x2+y2+z2−1/2+ln(xyz) at the point left parenthesis negative 2 comma 1 comma negative 2 right parenthesis(−2,1,−2).

Which is the solution to the inequality? 2 3/52 1/15 b< 3 2/15 b> 3 2/15

Will possibly give brainliest and a high rating. choose the linear inequality that describes the graph. the gray area represents the shaded region. 4x + y > 4 4x – y ≥ 4 4x + y < 4 4x + y ≥ 4
