Quesuon 5 Which describes the graph of y=-(x + 6)2 + 6?
O A. Minimum at (6,6)
O B. Minimum at (-6, 6)
O C. Maximum at (6,6)
O D. Maximum at (-6, 6)

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3

daren is correct because

if a polygon ab c d e is transformed to congruent polygon mn o p q, then following possibilities can happen

1. rotation                 2. reflection             3. translation   4. reflection and then translation or vice versa     5. rotation and then reflection or vice versa     6. translation and rotation   or vice versa   7. all of three , rotation, then reflection and then translation or in any order.  

we will get a congruent polygon m n o p q which is congruent to a b c de.

now , polygon   m n o p q is translated 3 units right and 5 units down to get a   congruent polygon, v w x y z, so if vertices of   polygon   m n o p q is m(x,y), n(u,v), o(p,q), p(r,s) and   q(a,b)   this, then vertices of polygon, v w x y z will be ,v(x+3,y-5), w(u+3,v-5),o(p+3,q-5),p(r+3,s-5),q(a+3,b-5).
