Somesh earns Rs 890 each week. Which of the following is the best estimate for the money he earns in 52 weeks?

45000 Rs

Step-by-step explanation:

you have to round each number to 1 significant figure so 890 rounds to 900 and 52 rounds to 50

so 900 x 50 = 45000 Rs

This will be a underestimate as the actual amount of money he makes in 52 weeks is 52 x 890 = 46280 Rs

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
