Triangle pqr has vertices at p(−6,−4) , q(2,−10) , and r(8,0) . it is dilated about the origin by a scale factor of 5 to obtain triangle p′q′r′ . what are the coordinates of the vertices of triangle p′q′r′ ? use the drop-down menus to choose the coordinates that make the statement true.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
