1. Molly is investigating the change in motion of an object. She kicks a soccer ball that is sitting on a soccer field three times. Molly changes the force of her kick each time and uses a device to measure the force. The data she collected are shown in the table. Distance Traveled Force of Kick (N) 150 31 200 39 270 a. Describe two forces acting on the soccer ball when Molly kicks it.​

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
