Which of the following is a solution of 12 x - 7 &gt; 6?<br><br> -1<br> 0<br> 1<br> 2
Mkey [24]

Answer:

The answer to your question is "2"

Step-by-step explanation:

Data

       12x - 7 > 6

Process

1.- Add +7 in both sides of the inequality

       12x - 7 + 7 > 6 + 7

2.- Simplify

       12x >  13

3.- Divide by 12 both sides

         12x/12 > 13/12

                 x > 13/12    or   x >  1.08  

4.- Conclusion

     All the numbers higher than 1.08 are solutions of this inequality

    Then, from the choices, the only possible solution is 2.

A ball rolls over the edge of a platform with only a horizontal velocity. The height of the platform is 1.6 m and the horizontal
Sever21 [200]

Answer:

35 m/s

Step-by-step explanation:

Let gravitational acceleration g = 9.8m/s2. We can calculate the amount of time for the ball to fall vertically a distance of 1.6 m

1.6 = 9.8t^2/2

t^2 = 2*1.6/9.8 = 0.327

t = \sqrt{0.327} = 0.571s

This is also the time it takes for the ball to fly horizontally, assume constant horizontal speed, we can calculate the speed it takes to travel across 20m in 0.571s

v = 20 / 0.571 = 35 m/s
