Answer:
Step-by-step explanation:
I assume you want to rotate each point about the origin.
To rotate a point (x, y) 90° clockwise about the origin:
(x, y) → (y, -x)
For point A:
(-5, 0) → (0, 5)
For point B:
(-5, 3) → (3, 5)
For point C:
(0, 4) → (4, 0)
The answer is surely x3 ?
Answer:
72y2-45
Step-by-step explanation:
9y2 + 9(7y2 - 5)
you multiply the 9 by the stuff in the parentheses
9y2 + 63y2 - 45
72y2-45
Answer:
The potato bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn chip bag assembly line.
Step-by-step explanation:
Popcorn mean= μ`1= 3.06
Popcorn St. Dev= σ1= 0.02
Potato Mean= μ`2= 5.05
Potato St. Dev= σ2= 0.05
Finding the z score
z= x- u / σ
Popcorn z= 3.06- 3.03/0.02= 1.5
Potato Z= 5.05-5.07/0.05= -0.4
The mean is taken to be at zero ( 0) therefore difference of 0.4 is less than a difference of 1.5
Choice 3 is the best option .
Answer:
(4, -5)
Step-by-step explanation:
Use the (y, -x) rule when rotating points 90 degrees clockwise on a graph.
