The product of a number and 2 is 2n. When you substitute 18 for n, the solution is 2(18) or 36
At the time the cannonball reaches the ground, the vertical height of the cannonball from the ground is 0, i.e. h = 0.
Thus, the time it will take the cannonball to reach the ground is given by

Therefore, it will take the cannonball 8 seconds to reach the ground.

Answer:
Yes
Step-by-step explanation:
First find the slope(m)
Slope= y2-y1/x2-x1= (1-(-5))/(-1-(-2))= 6/1 = 6
Then find the y intercept (move up six and right one from (-1, 1) to get (0, 7)
The y-intercept is y=7
Now make the equation
Y= slope(x) + y-intercept
Y=6x+7
