Answer:
Slope (m) = 3, y-intercept (b) = -1
Step-by-step explanation:
First, we need to write the equation in y = mx + b.
To do this, add 3x to both sides.
y = 3x - 1 is your result.
Now, we have everything we need to do determine our slope and y-intercept in just this equation alone.
Remember, m = slope and b = y-intercept.
In this equation:
m = 3
b = -1
So your slope is 3, and your y-intercept is -1

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>
                      
 
        
             
        
        
        
The area of a hexagon is 
A= a^2 (3√3)/2
we replace a with 4
A=41.57
