Answer:

It takes 46 seconds for the plane to reach the ground.

Step-by-step explanation:

We are given the following in the question:

The height of the paper airplane above the ground is given by a function:

f(x) = -1.5x + 69

where f(x) is the height above the ground and x is the time in seconds.

a) The attached image shows the graph for the given equation.

As clear from the graph the unction has a y-intercept of 69 and x-intercept of 46.

b) We have to find the time taken by he plane to reach the ground.

The height of plane on ground is 0

Thus, we can write:

0 = -1.5x + 69\\1.5x = 69\\x = \displaystyle\frac{69}{1.5}\\\\x = 46

c) Thus, it takes 46 seconds for the plane to reach the ground from the top of the tall building to reach a height of 0.
