Answer:
For each number in set A, there is one mapping from set A (input) to set B (output), so the mapping represents a function
Step-by-step explanation:
The relation is a function if and only if each input value has only 1 output value
<u><em>Examples:</em></u>
- The relation {(1, 2), (-3, 5), (0, 10)} is a function because every input has only one output, the input 1 has only output 2, the input -3 has only output 5, the input 0 has only output 10
- The relation {(-1, -2), (3, -5), (-1, 1)} is not a function because the input -1 has two outputs -2 and 1
Let us solve the question
Use the given figure to find the inputs and their corresponding outputs
Set A →→→→ Set B
∵ -3 →→→→ 2
∵ -4 →→→→ 4
∵ 9 →→→→ -2
∵ 1 →→→→ 7
∵ Set A is the input and set B is the output
∵ There is only one arrow go from each value in set A to a value in set B
∴ For each number in set A, there is one mapping from set A to set B
∴ The mapping represents a function
For each number in set A, there is one mapping from set A (input) to set B (output), so the mapping represents a function
Answer:
$56.7
Step-by-step explanation:
Given
Earning per share=E=$2.70
P/E Ratio=21
The formula for P/E ratio is :
P/E Ratio=Price/Earning
Where Price is the price of share in stock and earning the amount earned on one share.
Putting the values of Earning and P/E ratio in the formula
21=Price/2.70
21*2.70=Price
Price=$56.7
So the stock price is $56.7..
A. because he had ridden less than 140 so 5s >140
