The x-intercepts are readily identified on the graph: (2,0) and (4,0). The midpoint of a line connecting those 2 points would be (3,0).
If they have 24 hours in a day, and use 1/6 of those 24 hours on news, they use 24*(1/6) or 4 hours on news. Assuming that they use the leftover time for just music and entertainment, we have 20h - 4h, so thats 20h. You were right. Not sure on their reasoning either.
Answer:
sqrt(104) =x
Step-by-step explanation:
We can use the Pythagorean theorem since this is the right triangle.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
2^2 + 10^2 = x^2
4+100 = x^2
104 = x^2
Take the square root of each side
sqrt(104) = sqrt(x^2)
sqrt(104) =x
I think it might be the second option
