Answer is<em> </em><em><u>3t²-6t</u></em>
<h3>
Step-by-step Explanation:-</h3>

Now we need to find velocity. The velocity is the first derivative of position, so let's find the derivative of s(t) :-

So,

Therefore, <u>v(t) = 3t²-6t</u>
X=4
JK=17
JM=19
KM=17
This is the answer
Answer:
A table of values is not going to be a function if two y values have the same x value.
If you run a vertical line through the x and get 2 y values, you are not dealing with a function. The one that does that is D. You have 3 and the two y values for x = 3. Those two y values are -4 and 0.

Answer:
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
Step-by-step explanation:
Let x = Courtney's walking speed
then
(x + 1) = Brandi's walking speed
:
Time = Distance/speed
Brandi walks 6.5 mi time = Courtney walks 5 mi time
6.5/x + 1 = 5/x
Cross multiply
6.5x= 5(x+1)
6.5x= 5x + 5
6.5x - 5x = 5
1.5x = 5
x = 5/1.5
x = 3.33 mph is Courtney's walking speed
Note that:
(x + 1) = Brandi's walking speed
3.33mph + 1 = 4.33mph
Therefore,
Courtney's walking speed = 3.33mph
Brandi's walking speed = 4.33 mph
