ANSWER
![2 \frac{1}{4}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B1%7D%7B4%7D%20)
EXPLANATION
We want to find the constant that must be added to
![{x}^{2} - 3x](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%203x)
to form a perfect square.
Comparing the given expression to
![a{x}^{2} + bx + c](https://tex.z-dn.net/?f=%20a%7Bx%7D%5E%7B2%7D%20%20%2B%20bx%20%2B%20c)
we have
a=1 , b=-3 , and c=0.
We need to add
![{( \frac{b}{2a} })^{2}](https://tex.z-dn.net/?f=%20%7B%28%20%5Cfrac%7Bb%7D%7B2a%7D%20%7D%29%5E%7B2%7D%20)
We substitute the values to get,
![{( \frac{ - 3}{2(1)} })^{2} = \frac{9}{4}](https://tex.z-dn.net/?f=%7B%28%20%5Cfrac%7B%20-%203%7D%7B2%281%29%7D%20%7D%29%5E%7B2%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B4%7D%20)
We change this to mix numbers to get,
![2 \frac{1}{4}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B1%7D%7B4%7D%20)
The last choice is correct.
Answer:
Step-by-step explanation:
As we have,
2sinxcosy = sin(x + y) + sin(x - y)
![=2sin70cos20\\\\=sin(70 + 20) + sin(70 - 20)\\\\=sin90 + sin50](https://tex.z-dn.net/?f=%3D2sin70cos20%5C%5C%5C%5C%3Dsin%2870%20%2B%2020%29%20%2B%20sin%2870%20-%2020%29%5C%5C%5C%5C%3Dsin90%20%2B%20sin50)
Hence, LHS=RHS
Answer:
>>> t = 3/2 - sqrt(111)/4
>>> t = 3/2 + sqrt(111)/4
Step-by-step explanation:
-16r^2 + 48t +75=0
>>> t = 3/2 - sqrt(111)/4
>>> t = 3/2 + sqrt(111)/4
For each, divide the amount by the number of wings
7 divided by 8: 0.875 = $0.88 per wing
10 divided by 12: 0.8333 = $0.83 per wing
17 divided by 20: 0.85 = $0.85 per wing
Looking at each result, the middle one (the $10 for 12 wings) is the best deal
