The problem uses the concept of Combination where there are number of members chosen from a group and there order is not important. Thus, the expression that would best describe the given above is 30C6 which means the combination of 30 taken 6. The numerical value for this is 593775.
Answer:
The second one.
Step-by-step explanation:
The pattern is red with 0 arrows, blue with 1 arrow, red with 2 arrows, so it would be blue with 3 arrows.
Answer:
B
Step-by-step explanation:
The formula for the volume of a cylinder is
, where r is the radius of the base and h is the height of the cylinder.
![\pi \cdot 3.25^2 \cdot 10=105.625\pi \text{ cm}^3](https://tex.z-dn.net/?f=%5Cpi%20%5Ccdot%203.25%5E2%20%5Ccdot%2010%3D105.625%5Cpi%20%5Ctext%7B%20cm%7D%5E3)
Therefore, the correct answer is choice B. Hope this helps!

The addison see to the horizon at 2 root 2mi.
We have given that,Kaylib’s eye-level height is 48 ft above sea level, and addison’s eye-level height is 85 and one-third ft above sea level.
We have to find the how much farther can addison see to the horizon
<h3>Which equation we get from the given condition?</h3>
![d=\sqrt{\frac{3h}{2} }](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5Cfrac%7B3h%7D%7B2%7D%20%7D)
Where, we have
d- the distance they can see in thousands
h- their eye-level height in feet
For Kaylib
![d=\sqrt{\frac{3\times 48}{2} }\\\\d=\sqrt{{3(24)} }\\\\\\d=\sqrt{72}\\\\d=\sqrt{36\times 2}\\\\\\d=6\sqrt{2}....(1)](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5Cfrac%7B3%5Ctimes%2048%7D%7B2%7D%20%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B%7B3%2824%29%7D%20%7D%5C%5C%5C%5C%5C%5Cd%3D%5Csqrt%7B72%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B36%5Ctimes%202%7D%5C%5C%5C%5C%5C%5Cd%3D6%5Csqrt%7B2%7D....%281%29)
For Addison h=85(1/3)
![d=\sqrt{\frac{3\times 85\frac{1}{3} }{2} }\\d\sqrt{\frac{256}{2} } \\d=\sqrt{128} \\d=8\sqrt{2} .....(2)](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%5Cfrac%7B3%5Ctimes%2085%5Cfrac%7B1%7D%7B3%7D%20%7D%7B2%7D%20%7D%5C%5Cd%5Csqrt%7B%5Cfrac%7B256%7D%7B2%7D%20%7D%20%5C%5Cd%3D%5Csqrt%7B128%7D%20%5C%5Cd%3D8%5Csqrt%7B2%7D%20.....%282%29)
Subtracting both distances we get
![8\sqrt{2}-6\sqrt{2} =2\sqrt{2}](https://tex.z-dn.net/?f=8%5Csqrt%7B2%7D-6%5Csqrt%7B2%7D%20%20%3D2%5Csqrt%7B2%7D)
Therefore, the addison see to the horizon at 2 root 2mi.
