The vertices of the image of GHJK after a translation are given. Choose the vector that describes the translation.

Lady_Fox [76]

Answer:

Option B

Step-by-step explanation:

Let's take a vertex G of quadrilateral GHJK to understand the rule for the translation,

From the graph attached,

Coordinates of G → (-5, 5)

Coordinates of the image point G' after the translation → G'(-5, 5)

Let the point G is translated 'a' units to the right and 'b' units down,

Rule for this translation,

G(x, y) → G'(x + a, y - a)

By this rule,

G(-5, 5) → G'(-5 + a, 5 - a)

-5 + a = -5 ⇒ a = 0

5 - a = 5 ⇒ a = 0

Therefore, vector that defines the translation will be,

<0, 0>

Option B is the the correct option.

-8cot square A + 8 cosec square A

zepelin [54]

Answer:

Step-by-step explanation:

Using the identity

cosec²A = 1 + cot²A

- 8cot²A + 8cosec²A

= - 8cot²A + 8(1 + cot²A)

= - 8cot²A + 8 + 8cot²A

= 8

Triangle MNO is reflected over the x-axis and then translated up 4 and right 3.

stepan [7]

Answer:

Translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis.

Step-by-step explanation:

The pre-image consists of points:

(1, 3), (2, 1), (-1, 2)

Translating them down 4 units, we get:

(1, 3-4), (2, 1-4), (-1, 2-4)

(1, -1), (2, -3), (-1, -2)

Translating them right 3, we get:

(1+3, -1), (2+3, -3), (-1+3, -2)

(4, -1), (5, -3), (2, -2)

Reflecting them over the x-axis., we get:

(4, -(-1)), (5, -(-3)), (2, -(-2))

(4, 1), (5, 3), (2,2)

which correspond to the points of the image
