Answer:
125
Step-by-step explanation:
25 × 5 = 125
x/5 = 25 × 5 = 125
x = 125
We have the following:
![10x^2-x+9=0](https://tex.z-dn.net/?f=10x%5E2-x%2B9%3D0)
solving:
![\begin{gathered} 10x^2-x+9=0 \\ 10x^2-x+9-9=-9 \\ 10x^2-x=-9 \\ \frac{10}{10}x^2-\frac{x}{10}=-\frac{9}{10} \\ x^2-\frac{x}{10}+(-\frac{1}{20})^2=-\frac{9}{10}+(-\frac{1}{20})^2 \\ (x-\frac{1}{20})^2=-\frac{359}{400}\rightarrow(x-\frac{1}{20})=\sqrt[]{-\frac{359}{400}} \\ x=\frac{1}{20}+i\frac{\sqrt{359}}{20} \\ x=\frac{1}{20}-i\frac{\sqrt{359}}{20} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2010x%5E2-x%2B9%3D0%20%5C%5C%2010x%5E2-x%2B9-9%3D-9%20%5C%5C%2010x%5E2-x%3D-9%20%5C%5C%20%5Cfrac%7B10%7D%7B10%7Dx%5E2-%5Cfrac%7Bx%7D%7B10%7D%3D-%5Cfrac%7B9%7D%7B10%7D%20%5C%5C%20x%5E2-%5Cfrac%7Bx%7D%7B10%7D%2B%28-%5Cfrac%7B1%7D%7B20%7D%29%5E2%3D-%5Cfrac%7B9%7D%7B10%7D%2B%28-%5Cfrac%7B1%7D%7B20%7D%29%5E2%20%5C%5C%20%28x-%5Cfrac%7B1%7D%7B20%7D%29%5E2%3D-%5Cfrac%7B359%7D%7B400%7D%5Crightarrow%28x-%5Cfrac%7B1%7D%7B20%7D%29%3D%5Csqrt%5B%5D%7B-%5Cfrac%7B359%7D%7B400%7D%7D%20%5C%5C%20x%3D%5Cfrac%7B1%7D%7B20%7D%2Bi%5Cfrac%7B%5Csqrt%7B359%7D%7D%7B20%7D%20%5C%5C%20x%3D%5Cfrac%7B1%7D%7B20%7D-i%5Cfrac%7B%5Csqrt%7B359%7D%7D%7B20%7D%20%5Cend%7Bgathered%7D)
The answer is the last option
What do you mean by saying below?
Answer:
5.007 * ![10^{-3}](https://tex.z-dn.net/?f=10%5E%7B-3%7D)
Step-by-step explanation:
Move the decimal to the right three times to get 5.007
Then multiply the new number by
to make the 5.007 equal to 0.005007.
