For part a: you just need to find how far the vertex has been moved from the origin, or the point (0,0). As the vertex is at the point (2,-3), it has been translated right 2 horizontally and down 3 vertically.
For part b: you use the info found in part a to create the equation in the form of y=A(x-h)^2+k. In this case, A =1, so you can ignore it. The h value is the horizontal distance the vertex has been moved. Since it has been moved right 2, this part of the equation would be (x-2). I know it seems like it should be plus 2, but values in parentheses come out opposite. For the k value, find the vertical shift, which is down3, or -3.
Now that you have h and k, substitute them back into the equation.
Your final answer for part b is: y=(x-2)^2 -3.

5.12 x 10*
(the * should be a little number 4 in the corner)
Divide the given angle by 360, then multiply by 2 x radius x PI:
85/360 x (2 x 14 x PI)
85/360 x 87.96459 = 20.769 ( Round answer as needed)
Or if needed in terms of pi : 6.61PI
You did not say how the answer needed to be rounded.
