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. :)
Answer: The answer is 3/8
Step-by-step explanation: For this problem you only need to multiply the fractions. So when you multiply the two fractions you first multiply both numerators so 1 X 3 = 3 then the denominators 4 X 2 = 8. So the fraction is 3 over 8 3/8.
Hope this helps.
Answer: 1/8, 2/8, 3/8, or 4/8
Step-by-step explanation:
Make the 5 lower.
Answer: 7.02 is 10.4% of 67.5.
Since this is a ratios and proportions problem, you would set up the equation like this:
1/50,000 = x/8 x is the length of the distance on the map
After that, you cross multiply and you will get 50,000x=8
You then solve for x to get 0.00016
