Indicated here when h(t) = 0, we are to find for the time where the football has reached a certain height. 
Then, the values of t would be -0.2 and 2.7.
Since we are to look for the time, it is impossible for us to have an answer that has a negative value. So based from our answer, the solution that we will eliminate is the -0.2 one. Since its value is negative.
So, the correct value would be the 2.7 sec. one.
        
                    
             
        
        
        
Answer:
5. m<1 = 114 degrees
    m<2 = 66 degrees
6. 2x + 3x + 4x = 9x = 180, x = 20

X² - 3x - 10
x² = x * x
10 can be factored:
1 x 10 ⇒⇒⇒ difference between factors = 9 
2 x 5   ⇒⇒⇒ difference between factors = 3  ⇒ (The correct pair)
(x-5)(x+2) = x(x+2) - 5(x+2) 
                 = x² + 2x - 5x - 10 
                 = x² - 3x - 10
∴ x - 5 = 0  ⇒⇒⇒ x = 5
   x + 2 = 0  ⇒⇒⇒ x = -2
