Answer:
A,C, and D I believe.
Step-by-step explanation:
We want to find one-half of the reciprocal of 7/sqrt(98). Let's write down an expression for this:
![\dfrac{1}{2} \times \dfrac{\sqrt{98}}{7}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cdfrac%7B%5Csqrt%7B98%7D%7D%7B7%7D)
We can rewrite 98 into ![2 \times 49](https://tex.z-dn.net/?f=2%20%5Ctimes%2049)
![\dfrac{1}{2} \times \dfrac{\sqrt{2 \times 49}}{7}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cdfrac%7B%5Csqrt%7B2%20%5Ctimes%2049%7D%7D%7B7%7D)
![=\dfrac{1}{2} \times \dfrac{\sqrt{2} \times \sqrt{49}}{7}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cdfrac%7B%5Csqrt%7B2%7D%20%5Ctimes%20%5Csqrt%7B49%7D%7D%7B7%7D)
The square root of 49 is 7
![=\dfrac{1}{2} \times \dfrac{\sqrt{2} \times 7}{7}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cdfrac%7B%5Csqrt%7B2%7D%20%5Ctimes%207%7D%7B7%7D)
![=\dfrac{1}{2} \times\sqrt{2}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%5Csqrt%7B2%7D)
![=\dfrac{\sqrt{2}}{2}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Csqrt%7B2%7D%7D%7B2%7D)
This should be your answer. Let me know if you need any clarifications, thanks!
