(2B +5A)/7 = (2(-2, -12) +5(-9, 2))/7 = (-4-45, -24+10)/7 = (-7, -2)
Selection B is appropriate.
Answer:
The coordinates of P' are (4.8,-4.8).
Step-by-step explanation:
The rule of dilation
represent the dilation with scale factor 2.4 and center at origin.
If the scale factor of the dilation is k and the center is (0,0), then
![(x,y)\rightarrow (kx,ky)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%20%28kx%2Cky%29)
Since the scale factor is 2.4, therefore
![(x,y)\rightarrow (2.4x,2.4y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%20%282.4x%2C2.4y%29)
From the given figure it is noticed that the coordinates of P are (2,-2). The coordinates of P' are
![P(2,-2)\rightarrow P'(2.4(2),2.4(-2))](https://tex.z-dn.net/?f=P%282%2C-2%29%5Crightarrow%20P%27%282.4%282%29%2C2.4%28-2%29%29)
![P(2,-2)\rightarrow P'(4.8,-4.8)](https://tex.z-dn.net/?f=P%282%2C-2%29%5Crightarrow%20P%27%284.8%2C-4.8%29)
Therefore the coordinates of P' are (4.8,-4.8).
Answer:last one
Step-by-step explanation:
Answer:
3432
Step-by-step explanation:
Total bands = 14
Bands played = 7
The possible lineups can be calculated using Combination.
So, the possible lineups are 14C7
=> ![\frac{14!}{7!(14-7)!}](https://tex.z-dn.net/?f=%5Cfrac%7B14%21%7D%7B7%21%2814-7%29%21%7D)
=> 3432
Answer:
