Aparabola with vertex (h, k) and a vertical axis of symmetry is modeled by the equation y - k = a(x - h)2. determine the vertex for a parabola modeled by y = (x − 5)2 + 8

The vertex is (5,8) assuming you mean (x-5)^2 which is he correct way to represent to the power of

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
