The answer is 10 2/11. I hope this helps!
Solution:
we have been asked to find the potential roots of the function
![f(x) = 5x^3-7x + 11](https://tex.z-dn.net/?f=f%28x%29%20%3D%205x%5E3-7x%20%2B%2011)
using rational root theorem.
Here the constant term is 11 with factors 1 and 11 and the leading coefficients is 5 with factors 1 and 5.
So the potential roots of the given function as per the rational root theorem is
![\pm\frac{1,11}{1,5} =\pm\frac{1}{1,5} ,\pm\frac{11}{1,5}=\pm\frac{1}{1} ,\pm\frac{11}{1}\pm\frac{1}{5} ,\pm\frac{11}{5}\\\\\\\text{Hence the potential roots are }\\\\\pm1,\pm11,\pm\frac{1}{5},\pm\frac{11}{5}](https://tex.z-dn.net/?f=%5Cpm%5Cfrac%7B1%2C11%7D%7B1%2C5%7D%20%3D%5Cpm%5Cfrac%7B1%7D%7B1%2C5%7D%20%2C%5Cpm%5Cfrac%7B11%7D%7B1%2C5%7D%3D%5Cpm%5Cfrac%7B1%7D%7B1%7D%20%2C%5Cpm%5Cfrac%7B11%7D%7B1%7D%5Cpm%5Cfrac%7B1%7D%7B5%7D%20%2C%5Cpm%5Cfrac%7B11%7D%7B5%7D%5C%5C%5C%5C%5C%5C%5Ctext%7BHence%20the%20potential%20roots%20are%20%7D%5C%5C%5C%5C%5Cpm1%2C%5Cpm11%2C%5Cpm%5Cfrac%7B1%7D%7B5%7D%2C%5Cpm%5Cfrac%7B11%7D%7B5%7D)
Answer:
A. 5/13
Step-by-step explanation:
Cos is the adjacent side/hypotenuse
Cos C = 10/26 = 5/13
B because each input has one output
You answer is A 12 because you need to divide 152 and 12
