Okay, well first look at the graph of the point "D". A translation from (7, -3) to (2, 5) is a movement of 8 units up, and 5 units left. So the conversion factor is (8, -5).
Now, I understand the points of the triangle are at (1, 4) (3, -2) and (4, 0). To reflect across the x-axis, to do this, merely flip the signs of the y-values of the coordinates.
A(1, 4) = A'(1, -4)
B(3, -2) = B' (3, 2)
C(4, 0) = C'(4, 0)
And that's all folks!
Answer:
=15.4
Step-by-step explanation:
6^2+(3.4)-24 = 36+3.4−24
36+3.4−24
39.4−24
=15.4
Quick answer
Any irrational number. I can't think of any exception to this statement.
sqrt(5) is irrational. 1/2 * sqrt(5) is still irrational.
-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational
2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.
1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.
Conclusion
There are no exceptions to this. All irrational numbers produce irrationals when multiplied by 1/2
15. 145. 360-90-95-30
16. 90
The other picture number 16 again I already did that one.
Your expected value is -$0.62.
We multiply the probability of winning by the amount won. There are 12 face cards out of 52 cards, and the amount won is 4:
12/52(4)
We also multiply the probability of losing by the amount lost. There are 40 cards that are not face cards out of 52, and the amount lost is 2:
40(52)(-2)
Adding these, we have:
(12/52)(4)-(40/52)(2) = -0.62.
