When the object reaches the ground, the height is zero, so:
0 = 144 - 16t^2
then you just solve for t, so subtract the 144 over
-144 = -16t^2
then divide by the -16
9 = t^2
then take the square root of both sides
3 = t
therefore, it will take three seconds for the object to reach the ground.
The perimeter is the sum of all the sides, so P = (5x -7) + (3x-4) + (2x -6). Then group like terms so you have p = 5x + 3x + 2x -7-4-6 and end up with P = 10x - 17

Raymond's change was $ 4.
Since Raymond frequently dined at his favorite restaurant, Hungry Hippo, and at his most recent visit, he paid his bill, and if the bill had been half as much, he would have gotten three times as much change, while if the bill had been two dollars more, Raymond would have gotten only half as much change as he actually did get, to determine how much was Raymond's change the following calculation must be performed:
- 1 / 2X = 3Y
- X + 2 = 1 / 2Y
- X = Y
- 2 = 1 / 2Y
- Y = 2 x 2
- Y = 4
Therefore, Raymond's change was $ 4.

The correct graph for the given sets of equation is given attached below.
Equation no 2 gives the perfect solution to the graph.
<h3>What is a parabola?</h3>
A parabola, is cross section cut out of the cone and represented by an equation 
Clearly, by property of the parabola, the curve of parabola should symmetric to its axis. From this property set of Equation (2) i.e. downward opening parabola increasing from negative 2 comma negative 3 to a maximum at 0 comma 1 and then decreasing through the point 2 comma negative 3 Holds the property of the parabola
Thus, the required solution for the sets of equation (2) is given in the attachment.
