Answer:
a) f(50) = 7
b) for a population of 20000 people, the amount of paper being recycled is 3 tons.
Explanation:
A function shows the relationship between two or more variables (an independent variable and a dependent variable), relating the input to output. The independent variable does not depend on any variable and it is also the input while the dependent variable depends on other variables and it is the output
a) Since the function is given as R = f(p), a population of 50,000 and recycles 7 tons of garbage each week is represented as:
f(50) = 7
f(50) means 50000 people and the 7 means 7 tons
b) f(20) = 3 means that for a population of 20000 people, the amount of paper being recycled is 3 tons.
Cooperatives provided a market for farmers' goods and products at lower costs. They did not work because farmers often had to buy on credit and the cooperatives were a cash-only system.
The answer is B) 2 and 3
When you do a Riemann's sum, you split the interval into columns. In choice 3 we are told that there are 4 equal subdivisions meaning that each of the 4 columns are 1 wide. Since it is a left Riemann's sum we add the height of the column where the LEFT side crosses the curve. For [-1, 0], the height is -1, for [0, 1] it is 0, for [1, 2] it is 2, and for [2, 3] it is 3. Now add the heights together to get 4. Then you multiply by the width, but since the columns are 1 wide, the answer is still just 4.
