C . the graph will shift upwards because it is increasing on a graph
To solve for the time an object takes to hit the ground, the equation
<em>y</em> <em>= y₀ + v₀t + ½gt²</em>, or just <em>0 = y₀ +½gt²</em> since there is no initial velocity and the final y position is 0 (since it is on the ground). Therefore, <em>t = (−2y₀/g)^½.</em>
(-2*60/-9.8)^½ = 3.50 seconds.

Answer:
B
Step-by-step explanation:
Well, using a+b=c , it would mean that 12+b=35. therefore b would equal 23 if that’s what you’re looking for
Answer:
D
Step-by-step explanation:
Try to remember this formula.
![y=a|b(x-c)|+d](https://tex.z-dn.net/?f=y%3Da%7Cb%28x-c%29%7C%2Bd)
Where a is the vertical multiplier, b is the horizontal multiplier, c is the x coordinate of the vertex, and d is the y coordinate of the vertex.
Since the vertex on the graph is (2,3), c and d have to be 2 and 3.
Also, there are no vertical/horizontal stretches so the a and b values stay at 1.
The final equation would come out to ![y=|x-2|+3](https://tex.z-dn.net/?f=y%3D%7Cx-2%7C%2B3)
