Aright triangle is drawn on a coordinate plane. two vertices of the triangle are points a(−2,4) and b(3,−2) . the third vertex of the triangle is point c, which lies in the third quadrant of the coordinate plane. what is the distance from point a to point c? enter your answer in the box

15 points ! ~ see if you know the answer to both you!

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).

I’m still confused on how to work the percentages
