Answer:
(x,y) -> (-y,x), second option.
Step-by-step explanation:
Rotation of 90 degrees about the origin:
The rule for a rotation of a point (x,y) 90 degrees about the origin is given by:
(x,y) -> (-y,x)
This is that the question asks, and so, this is the answer, which is the second option.
Step-by-step explanation:
12 = 2 × 2 × 3
18 = 2 × 3 × 3
56 = 2 ×2 × 2 × 7
Now
Common factor = 2
Remaining factor = 2 × 3 × 2 × 3 × 7
LCM = RF × CF
= 504
hence the lCM of 12 , 18 and 56 is 504...

Answer:
x^2 = 10^2 - 9^2
x^2 = 100 -81 = 19
x = 4.3588989435
The triangle sides are 10, 9 and 4.3588989435

Answer:
2
Step-by-step explanation:
You set up and equation:
5+6x = 17
You solve it and get 2.
Answer:
Step-by-step explanation:
Given that Poker is a card played with a standard 52 card playing deck. We draw one card at a time without replacement from the top of a shuffled standard poker deck and stop when we draw an ace.
There are 4 aces and 48 non aces.
For randomly drawing card for first card we have probability for drawing ace = 4/52 and non ace = 48/52
X = no of cards we have drawn
If X is the total no of cards drawn, then the event should have been
first x-1 cards non aces, and the last card ace.
Hence P(X)
= Drawing x-1 cards from 48 non aces * drawing one card from remaining 52-(x-1) cards
=
, x=1,2,.....49
