For f(x) = 12/(1+x²), and subinterval width 4, you are to evaluate f(1), f(5), and f(9) and combine them according to the rule
... Integral ≈ (4/3)(f(1) + 4·f(5) + f(9)) = (4/3)(6.0000 + 4·0.4615 + 0.1463) ≈ 10.66
_____
Simpson's rule has you combine values of f(x) with coefficients 1, 4, 2, 4, ..., 2, 4, 1, where those values are evenly spaced at the edges of an even number of subintervals. Since we have only 3 values to combine, there are no terms that have a coefficient of 2. The entire sum is multiplied by 1/3 the subinterval width.
Answer:
9 Miles to be specific 8.95
Step-by-step explanation:
3 miles = 4.83 km
4.83 km = 4830 m
60 seconds X 45 =2700 Seconds
4830 divided by 2700 = 1.78 m/s
you want to know the distance so its speed X time
135 minutes X 60 seconds = 8100 secs
1.78 m/s X 8100 =14418 meters
14418 = 14.418 km
14.418 km = 9 miles
P.S. There is a shorter version but i think this is simpler for me and I use metric units.
7-3=-x+1
4=-x+1 substract 1
-1 -1
4-1=-x
3=-x multiply by -1
•(-1) •(-1)
-3=x
x=-3
D is the answer because 13 goes into 5 twice and 3 Is left over multiply that by two to get 6/10 than that it's equivalent to .6 so it is 2.6
You will do 60/2 to = 30 because the ratio of peaches to cherries is 2:3 and they need to have a unknown number of peaches lets say thats “x” therefore 60/2=x ,x=30 cups of peaches
