Hello there!
0.8 is not irrational
If a number can be written with a perfect fraction, it is rational

Hey there!
B in a slope intercept form equation is the the y intercept. It dictates where the line will cross the y axis, and therefore the line's placement altogether. This is because if there was no y intercept, the line would only be shaped by the slope, and would start at 0.
Hope this helped!
        
             
        
        
        
Answer:
See below
Step-by-step explanation:
Y component of velocity is 70 sin 30° 
y position =   3  + 70 sin 30°  * t    - 1/2 a t^2 
  when the ball hits the ground  y = 0 
        0 = 3 + 70 sin 30°  t  - 1/2 (32.2)t^2 
            - 16.1 t^2 + 35t + 3 = 0   
                     Use Quadratic Formula to find t = <u>2.26 seconds</u>
Horizontal component of initial velocity 
  70 cos 30°             distance horizontal = 70 cos 30°  * t 
                                    = 70 cos 30°  (2.26) =<u> 137.0 ft</u>
