Answer:
![{19}C_1=19](https://tex.z-dn.net/?f=%7B19%7DC_1%3D19)
Step-by-step explanation:
We need to find the value of
.
C stands for combination.
The formula of combination is as follows :
![nC_r=\dfrac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=nC_r%3D%5Cdfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D)
Here,
n = 19 and r = 1
So,
![nC_r=\dfrac{19!}{1!(19-1)!}\\\\nC_r=\dfrac{19!}{1!\times 18!}\\\\nC_r=\dfrac{19\times 18!}{1!\times 18!}\\\\nC_r=19](https://tex.z-dn.net/?f=nC_r%3D%5Cdfrac%7B19%21%7D%7B1%21%2819-1%29%21%7D%5C%5C%5C%5CnC_r%3D%5Cdfrac%7B19%21%7D%7B1%21%5Ctimes%2018%21%7D%5C%5C%5C%5CnC_r%3D%5Cdfrac%7B19%5Ctimes%2018%21%7D%7B1%21%5Ctimes%2018%21%7D%5C%5C%5C%5CnC_r%3D19)
So, the value of
is 19.
Well if you make 950 dollars every two weeks, in a month you will have 1,900. Then take 12% of 1,900, and you will have 228 dollars to spend a month on groceries.
Answer:
The height of the rock formation is ![45.02\ ft](https://tex.z-dn.net/?f=45.02%5C%20ft)
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
![tan(42\°)=h/50](https://tex.z-dn.net/?f=tan%2842%5C%C2%B0%29%3Dh%2F50)
solve for h
![h=50*tan(42\°)=45.02\ ft](https://tex.z-dn.net/?f=h%3D50%2Atan%2842%5C%C2%B0%29%3D45.02%5C%20ft)
