Answer:
B) the cube of 4 and then take the square root
Step-by-step explanation:
43/2 = 21.5
___
The answer choices suggest you want ...
4^(3/2) . . . . . . . appropriate math symbols are very helpful
This can be evaluated several ways:
![4^{\frac{3}{2}}=\sqrt{4^3}=(\sqrt{4})^3=10^{\frac{3}{2}\log{4}}\\\\=8](https://tex.z-dn.net/?f=4%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%3D%5Csqrt%7B4%5E3%7D%3D%28%5Csqrt%7B4%7D%29%5E3%3D10%5E%7B%5Cfrac%7B3%7D%7B2%7D%5Clog%7B4%7D%7D%5C%5C%5C%5C%3D8)
_____
Since the 3 is in the numerator of the fraction, it represents a cube, not a cube root. Any of the answer choices suggesting cube root is involved are incorrect. (Eliminating those leaves only the correct answer choice.)
Answer: 7.58 years
Step-by-step explanation:
When it comes to finding out how long it will take for an investment to double, one can use the Rule of 72.
The Rule of 72 estimates the amount of time it will take to double an investment when you divide 72 by the interest rate:
= 72 / r
= 72 / 9.5
= 7.58 years
Answer:
Step-by-step explanation:
From the problem statement, we can set up the following two equations:
![K + N = 30](https://tex.z-dn.net/?f=K%20%2B%20N%20%3D%2030)
![20K + 10N = 500](https://tex.z-dn.net/?f=20K%20%2B%2010N%20%3D%20500)
where
is the number of Knicks players, and
is the number of Nets players.
We can substitute the first equation into the second and solve for ![K](https://tex.z-dn.net/?f=K)
![K + N = 30](https://tex.z-dn.net/?f=K%20%2B%20N%20%3D%2030)
![N = 30 - K](https://tex.z-dn.net/?f=N%20%3D%2030%20-%20K)
![20K + 10N = 500](https://tex.z-dn.net/?f=20K%20%2B%2010N%20%3D%20500)
![20K + 10(30 - K) = 500](https://tex.z-dn.net/?f=20K%20%2B%2010%2830%20-%20K%29%20%3D%20500)
![20K + 300 - 10K = 500](https://tex.z-dn.net/?f=20K%20%2B%20300%20-%2010K%20%3D%20500)
![10K + 300 = 500](https://tex.z-dn.net/?f=10K%20%2B%20300%20%3D%20500)
![10K = 200](https://tex.z-dn.net/?f=10K%20%3D%20200)
![K = 20](https://tex.z-dn.net/?f=K%20%3D%2020)
