For a moving object, the force acting on the object varies directly with the mass of the object. Suppose that an object whose mass is 15 kg is acted upon by a force of 90N. Find the force needed to move an object whose mass is 10 kg.

Right triangle lmn has vertices l(7, –3), m(7, –8), and n(10, –8). the triangle is translated on the coordinate plane so the coordinates of l’ are (–1, 8). (x, y) → (x + 6, y – 5) (x, y) → (x – 6, y + 5) (x, y) → (x + 8, y – 11) (x, y) → (x – 8, y + 11)

Quadrilateral wxyz was dilated with the origin as the center of dilation to create quadrilateral w'x'y'z'. the quadrilateral was dilated using a scale factor of 2. the coordinates of the vertices of quadrilateral wxyz are given. you can use the scale factor to find the coordinates of the dilated image. enter the coordinates of the vertices of quadrilateral w'x'y'z'
