Question

I’m tired of being trolled. I really need help with this. I will mark brainliest.. just please help me.


1. Approximate the intervals over which the acceleration is increasing. Write in interval or union of intervals.

I think (0,10) U (62,183)

2. Approximate the decreasing in interval/union of intervals
I think (10,62) U (183,200) but idk

3. how many turning points does the graph show?

4. Based on the number of turning points, what is the minimum degree of a polynomial function that could be used to model acceleration versus time? Would the leading coefficient be positive or negative?

5. Approximate the time when the acceleration was the greatest.

6. Approximate the value of the maximum acceleration

Answer 1

Step-by-step explanation:

Hey there!

It looked like people were helping you with the first 2, so l'll pick up from there.

3. The graph changes direction 3 times, so it shows 3 turning points.

4. x^4 is the minimum degree polynomial model, because there are 3 turning points.

5. Look at where the graph was highest. 180 appears to be the closest number to that peak, so 180 sec is correct.

6. Look at the rise again. Where is the accelaration placed on the left side of the chart? It looks to me like 3 is closest.

I'll be waiting in the comments if you need help. :)
