The half-life is the time it takes for only half of something to remain. For example, if there are 100 atoms, after one half-lif
yarga [219]
First we define the variable to be used:
 x: half-life time period
 The equation for this problem can be modeled as:
 y = A * (b) ^ x
 Where,
 A: initial amount
 b: decrease rate.
 For example:
 if there are 100 atoms, after one half-life time period, 50 atoms remain:
 y = 100 * (0.50) ^ x
 after one half-life time period (x = 1):
 y = 100 * (0.50) ^ 1
 y = 50
 The equation that models the problem is:
 y = 16 * (0.50) ^ x
 The table is:
 1     8
 
2     4
 
3     2
 
4     1

PLEASE HELP?!?!?!

Answer:

c. In 2 seconds, the commuter train travels 120 feet.

Step-by-step explanation:

Given

The attached graph

Required

What does x-coordinate of 2 represents

Represent this coordinate with (x,y)

From the graph:

x = 2 when y = 120

Note that:

x = time and y = distance

So:

(x,y) = (2,120)

Which means:

At 2 seconds, the train has travelled a distance of 120ft

<em>From the list of options, (c) is correct</em>
