which class are you bro I can't solve it XD
Answer:
(- 3, 5 ) & (-2,7)
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) , thus
(5, 3 ) → (- 3, 5 )
Under a counterclockwise rotation about the origin of 90.
a point (x, y ) → (- y, x ) , thus
(7, -2 ) → (-2, 7)
Simplified
There are 6 numbers on a die. So the probability over all to get either of those 6 numbers is 1/6 if you roll just once. The only number that is odd and less than 3 is 1. 1 is one of those 6 numbers so the probability to get a number odd and less than three in 18 rolls is 3/18 which is also 1/6 if it needs to be simplified
Answer:
Step-by-step explanation:
One
<em>Part A</em>
5, -3*5, (-3)^2 * 5, (-3)^3*5, (-3)^4 * 5
5, - 15, 45, -135, 405
<em>Part B</em>
Second term = -15
Fourth term = -135
The difference = -15 - (-135) = 120
Two
(4 + 2)*(6-2)/(-1)
(8/2) * (5 + 1) * (2 - 1)/(-1)
(16/4) * (3+3) * (2 -1) / (- 1)
(30 - 6) * (0 + 1) / - 1
