I’m pretty sure the answer is B. Periodic motion is when the motion of an object is repeating itself, like back and forth or circling in an orbit and whenever you bounce a ball, you continuously bounce it back and forth.
Answer:
Step-by-step explanation:
This quadratic models the parabolic motion equation

where h is the height of the object after the motion occurs, a is the pull of gravity, v(i) is the initial vertical velocity of the object, and h(i) is the height from which the object was initially launched. If we are looking for when the ball hits the ground, h = 0, because the height of an object on the ground has no height at all (or 0 height). To find the time the object was in the air, factor the quadratic and solve for the values of t.
Two factors of 4 that add up to be 3 and multiply to be 4 are -1 and 4. So t=-1 and t = 4. Since we know that time can never be negative, then t = 4 seconds.
Which ever expression is 3x + 21 + 10 ..... 21 + 10 = 31 .... So it'll be 3x + 31 .
Answer:
a and b are similarity i think that's what your looking 4 idk
