The twelve cups have to be divided evenly between the seven jars
Answer:
x=5
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the side of the large triangle.
9 15
------ = ----------
2x-1 3x
Using cross products
9*3x = 15(2x-1)
27x = 30x-15
Subtract 30x from each side
27x-30x = 30x-30x -15
-3x = -15
Divide by -3
-3x/-3 = -15x/-3
x = 5
Length of the subintervals:
Using Upper Riemann sum,
∑Max{f(x_i) delta(x)
Lower sum for n=2:
The minimum value for the function on is 2.
