Answer:
Step-by-step explanation:
as the chart is broken into steps with the same precision we're looking for. Just choose the one where height is closest to zero or 0.6 s
To do it mathematically
The equation is
h = 2 - ½gt²
to find g, plug in a time and height
0.236 = 2 - ½g(0.6²)
g = 9.8 m/s
check another one just to be sure
1.559 = 2 - ½(9.8)0.3²
1.559 = 1.559
now plug in zero elevation with an unknown time
0 = 2 - ½(9.8)(t²)
-2 = - ½(9.8)(t²)
t² = 4/9.8
t = 0.6388765...
t = 0.6 s
The value of x in the equation is - 3.
<h3>How to find the variable in an equation?</h3>
Variables are number represented by a letter in an equation.
Therefore,
-5x - 9 = 2x + 12
subtract 12 from both sides of the equation
-5x - 9 = 2x + 12
-5x - 9 - 12 = 2x + 12 - 12
-5x - 21 = 2x
add 21 to both sides of the equation
-5x - 21 = 2x
-5x - 21 + 21 = 2x + 21
-5x = 2x + 21
subtract 2x from both sides
-5x = 2x + 21
-5x - 2x = 2x -2x + 21
-7x = 21
divide both sides by -7
-7x / -7 = 21 / - 7
x = -3

To translate a function up or down you add a constant to the function...2 units downward means you must subtract 2 from the original equation...
g(x)=f(x)-2
g(x)=2x^2-8-2
g(x)=2x^2-10
