After undergoing a displacement of 18.4m, an object has a final position of 53.5.what was its initial position (unit=m)

The initial position was 35.1 m

Step-by-step explanation:

Let

x > the initial position

we know that

The linear equation that represent this problem is equal to

x+18.4=53.5

Solve for x

Subtract 18.4 both sides

x=53.5-18.4

x=35.1 m

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
