PLS help a. Is the relationship between time and distance an arithmetic sequence?
Explain.

b. The total distance a freely falling body covers in time, t, is given by the equation d(t)=1/2 gt2, where g is constant at 10 m/s2. Show, in terms of n, the distance a falling body covers in t = n seconds of movement

c. Show, in terms of n, the distance a falling body covers in t = n - 1 seconds
of movement.

d. The distance a freely falling body covers in the nth second is given by
s(n)=d(n)-d(n-1). Show s(n) in terms of g, in simplified form.

e. Prove that the quantities s(n) form an arithmetic sequence.

step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

x = 3 ± √(5+y)

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
