Triangle ABC has the following coordinates: A (-2, 3) B (4, -3) C (-2, -3) What are the coordinates points for triangle A'B'C' i

hodyreva [135]

Answer: The coordinates of triangle A'B'C',

A'≡(3/2, -9/4)

B'≡(-3, 9/4)

C'≡(3/2, 9/4)

Step-by-step explanation:

Since, the rule of transforming the triangle ABC by the scale factor -3/4,

$(x,y)\rightarrow (\frac{-3}{4}x, \frac{-3}{4}y)$

Thus, the coordinates of the transformed triangle A'B'C',

$(-2, 3)\rightarrow (\frac{-3}{4}\times -2, \frac{-3}{4}\times 3)$

$(4, -3)\rightarrow (\frac{-3}{4}\times 4, \frac{-3}{4}\times -3)$

$(-2, -3) \rightarrow (\frac{-3}{4}\times -2, \frac{-3}{4}\times -3)$

So, the coordinates are A'≡(3/2, -9/4)

B'≡(-3, 9/4)

C'≡(3/2, 9/4)

Answer:

1/4

Step-by-step explanation:

Possible outcomes

For example let's name the tyre ABCD so the possible answer given by the students are

AA,AB,AC,AD,BA,BB,BC,BD,CA,CB,CC,CD,DA,DB,DC,DD.. Giving16 possible result

probability of giving same answer is

possible same answer is AA,BB,CC,DD. giving 4 possible result

Therefore 4/16 = 1/4
