Since h represents the height of the ball at any given time, t, let h = 25, such that the ball will be 25m high at t.
Now, we have 25 = 20t - 5t²
5t² - 20t + 25 = 0
t² - 4t + 5 = 0
Since the discriminant is less than zero, there are no solutions.
Hence, the ball will never be 25m high.

Answer:
Line d
Step-by-step explanation:
Line A could not be parallel to line C and neither cold line B because they would cross at some point. Line D is parallel because it would not cross line C at any point. Plane Q oculd not be parallel to line C because it is a plane and it is perpendicular to line C.
Answer:
x=14
Step-by-step explanation:
Adding all angles in this diagram sould get you 360. Because of this, we can use inverse operations to solve this. Subtract 90 and 60 from 360 to get 210. Now, the equation is 15x=210. Dividing both sides by 15 gets you 14. Hope this helps!
