Quadrilateral PQRS is transformed by translating it 6 units to the right and then rotating it 90° clockwise
Elina [12.6K]

Answer:

(y, -x -6)

Step-by-step explanation:

<em>The coordinates of PQRS is not given, however we'll assume the coordinates of PQRS to be (x,y)</em>

<em />

The first transformation: 6 units right

(x,y) -> (x + b, y)

Where b = 6

So, the new coordinates will be

(x + 6, y)

The second transformation: 90° clockwise

(x,y) -> (y,-x)

So, the new coordinates will be

(x + 6, y)-> (y, -x -6)

<em>Hence, the new coordinates of PQRS is (y, -x - 6)</em>

The angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.

<h3>How to calculate the angle?</h3>

It should be noted that the image shows the shooting angles arrangements. Also, π = 180°.

In this case, the value of the angle will be:

= 12π/18

= (12 × 180) / 18

= 12 × 10

= 120°

Therefore. the angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.

1) If the probability of it snowing tomorrow is 75%, what is the probability that it will
SCORPION-xisa [38]

Answer:

25%

Step-by-step explanation:

Since the probability of it snowing tomorrow is 75%, we already know that it's most likely it will snow. This 75% comes from a total of 100% chance of it snowing, which would be 75/100. So to find out the probability it WOULDN'T snow, just subtract 75 from 100

100 - 75 = 25

There is a 25% chance that it will not snow tomorrow.
