20) which rule yields the dilation of the figure rstu centered at the origin? a) (x, y) → (4x, 4y) b) (x, y) → (0.25x, 0.25y) c) (x, y) → (x + 4, y + 4) d) (x, y) → (x + 0.25, y + 0.25)

  A)

Step-by-step explanation:

The rule of dilating a shape by scale factor k centered at the origin is given by :-

 [We multiply k to the coordinates of pre-image ]

It means Option C) and D) is incorrect.

From the given graph , it can be observe that quadrilateral R'S'T'U' (image) is larger than the RSTU (pre-image) .

It means the scale factor should be greater than 1. [∵ Scale factor for enlargement is k>1]

Then, Option B is also incorrect.

Hence, the rule yields the dilation of the figure RSTU centered at the origin is given by option A)

i.e.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
