Step-by-step explanation:
The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:
Given interval: -2 ≤ x ≤ 2
Substituting the values into the equation:
I think it’s b I hope this help
Expressed in scientific notation the answer would be 3.05 X 10^6
Milk, tea and pearls in the ratio of 4:3:1 -> The milk = 4x, tea = 3x and pearls = x
So, 1560g is equal to 4x + 3x + x = 8x
x = 1560 / 8 = 195
3x = 195 x 3 = 585
4x = 195 x 4 = 780
So, she used 780g of milk, 585g of tea and 195g of pearls.
