There is some information missing in the question, since we need to know what the position function is. The whole problem should look like this:
Consider an athlete running a 40-m dash. The position of the athlete is given by 
where d is the position in meters and t is the time elapsed, measured in seconds.
Compute the average velocity of the runner over the intervals:
(a) [1.95, 2.05]
(b) [1.995, 2.005]
(c) [1.9995, 2.0005]
(d) [2, 2.00001]
Answer
(a) 6.00041667m/s
(b) 6.00000417 m/s
(c) 6.00000004 m/s
(d) 6.00001 m/s
The instantaneous velocity of the athlete at t=2s is 6m/s
Step by step Explanation:
In order to find the average velocity on the given intervals, we will need to use the averate velocity formula:
so let's take the first interval:
(a) [1.95, 2.05]
we get that:
so:
(b) [1.995, 2.005]
we get that:
so:
(c) [1.9995, 2.0005]
we get that:
so:
(d) [2, 2.00001]
we get that:
so:
Since the closer the interval is to 2 the more it approaches to 6m/s, then the instantaneous velocity of the athlete at t=2s is 6m/s
Answer: The sum of the interior angles of a polygon shown in the picture is 
.
Step-by-step explanation:
The given polygon is a regular pentagon having 5 sides.
The sum of the interior angles of a regular polygon is given by :-
, wherer n= number of sides of the regular polygon.
Since it has 5 sides, then the sum of the interior angles of a polygon would be
Hence, the sum of the interior angles of a polygon shown in the picture is .

If you look up “Four 4s Challenge” on yt you should find a couple videos explaining it! i just watched a little bit of one so i’ll try and help now though.
I’ll do 1-5 for you and try my best to explain :)) and if you need more answers or more help just let me know
So first, we need to find out how to get 1 using four 4s
1. (4/4)/(4/4)
this would read “four divided by four divided by four divided by four” which equals 1
2. 4/4+4/4
3. (4+4+4)/4
4. 4*(4-4)+4
5. (4*4+4)/4
Remember that you’ve gotta use an equation with just four 4s to get to every number
14xb + 2ya is your answer don't report this but if you use math you can get the answer like i did
