An object is launched into the air. The table below shows the object's height above the ground at various times. Based on the data in the table, which of the following is closest to the object's height above the ground 9 seconds after being launched?

720

step-by-step explanation:

first i did work 2nd i did work and 3rd i did work

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
