Question

Point A is launched horizontally away from a wall and a ( t ) a(t) represents Point A's distance from the wall (in meters) in terms of the number of seconds t t since the point was launched. Point D is launched from a platform that places it 1 meters from the wall, and Point D travels 1.5 times as fast as Point A. AD Click here to launch the points. Suppose d ( t ) d(t) represents Point D's distance from the wall (in meters) in terms of the number of seconds t t since the points were launched. Write a function formula for d d using the function a a.

Answer 1

Answer:

d(t) = 1 +1.5*a(t)

Step-by-step explanation:

Since point D is launched from a platform that places it 1 meters from the wall, we have  

d(0) = 1

Since point A is launched directly from the wall,  

a(0) = 0

but besides, point D travels 1.5 times as fast as point A, so

d(t) = 1 +1.5*a(t)

and this the function required.
