Answer:
The 1st Graph (A)
Step-by-step explanation:
Test by substituting values for "x":
<em>By substituting the numbers of 0</em> (0 < -3), <em>-1 </em>(-1 < -3), <em>and -2</em> (-2 < -3), <em>does that make the statement true</em>?
The answer is FALSE. None of those values are satisfactory.
---
<em>Therefore, by substituting</em> <em>-4</em> (-4 < -3), <em>-5</em> (-5 < -3), <em>and -6</em> (-6 < -3), <em>these values are satisfactory and makes the statement true</em>.
Do you want the answer or it written out? The written out would be down below and the answer is also down below in the x to the power of x equals 8/3 and its written out.
This question is incomplete, the complete question is;
Katie Ledecky swims the length of a 50m Olympic size pool in 25 seconds and swims the return trip to the starting position in 26 seconds. What are her average velocities during:
a) The first half of the swim?
b) The second half of the swim?
Answer:
a) her average velocities during the first half = 2 m/s
b) her average velocities during the second half = 1.923 m/s
Step-by-step explanation:
Given that;
displacement = 50 m
time taken t = 25 secs
a)
average velocity = displacement / time taken = 50 / 25 = 2 m/s
Therefore her average velocities during the first half = 2 m/s
b)
In the second half;
displacement = 50 m
time taken t = 26 secs
average velocity = displacement / time taken = 50 / 26 = 1.923 m/s
Therefore her average velocities during the second half = 1.923 m/s
From greatest to least it is: 7.89, 7.885, 7.8809, 7.88
Hope this helps!
This is an extended version of the answer only for the purpose of understanding because you can easily identify the equation by simply looking at the coordinates on the line
