A radical equation is an equation in which a variable (ex. x, y, a, v) is under a radical sign. The only equation that has a variable under a radical (x) is the second option. There is an x next to the 2 under the radical.
I hope this helps, DM me if you have anymore questions. :)
To determine the time it takes for the penny to reach the ground, we use the relation of height and time given above. We do as follows: <span> 0 =−4.9t^2+(0)t+150 t = sqrt( 150/4.9) t = 5.53 s
Hope this answers the question. Have a nice day.</span>

It is a linear function so you find the slope by doing y2-y1/x2-x1 and you find the slope to be 1/2. You can then setup an equation using it and graph it to find the next value.
