Here is a scale drawing of a garden. Tom wants to plant a tree in the garden according to the following rules:
It must be 6 m from A and 5 m from B.
Place a cross where Tom can plant the tree.
1 cm represents 2 m
D
С
2.5 cm
B

4 cm

1. are the triangles similar and if so why? what is the value of x? show your work.

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy

What is the perimeter of square abcd? units units 28 units 37 units
