If an object is dropped from a height of 45 feet, the function d = - 16t ^ 2 + 45 gives the height of the object after t seconds. Graph this function. Approximately how long does it take the object to reach the ground (d = 0) )?

The time taken by the object to reach the ground is (app.)

Explanation:

The given function is

To graph the function in the graph, let us substitute the values for t to find the value of d.

t             d

0           45

1            29

2          -19

3          -99

4          -211

5          -355

These values are plotted in the graph which is attached below:

To determine the time it takes the object to reach the ground, let us substitute in the function , we get,

The value of t cannot be negative.

Thus, (app.)

Thus, the time taken by the object to reach the ground is (app.)

false

step-by-step explanation:

whenever we assume a point on a plane then according to geometry it will definitely have 2 dimensions and if it assumed in space then it will have 3 dimensions.
