Answer:
a) (3, -4), (2, 4), (-5, -6)
b) (4, 3), (-4, 2), (6, -5)
Step-by-step explanation:
a) Reflection in the x-axis negates the y-coordinate:
(x, y) ⇒ (x, -y)
(3, 4) ⇒ (3, -4)
(2, -4) ⇒ (2, 4)
(-5, 6) ⇒ (-5, -6)
__
b) Reflection in the line y=x swaps the x- and y-coordinates:
(x, y) ⇒ (y, x)
(3, 4) ⇒ (4, 3)
(2, -4) ⇒ (-4, 2)
(-5, 6) ⇒ (6, -5)
Your answer should be 314
4 x 16=64
10 x 25 (25 is the height)=250
64 + 250=314
12 2 +16 2 = D2
D2= 144+256
D2= 400
D2= 400
Answer:
0.25
Step-by-step explanation:
Since, in the question , it is not mentioned that two balls of any specific colour,
the probability of getting two balls is: 
Fire truck because there are 6 designs and 6x2=12 but there are 3 left so it is plane, car, then firetruck
