Answer:
W = t + 200
Step-by-step explanation:
Number of words typed in the first letter = 200
The relationship between the total words typed, W and the number of seconds, t spent on the second letter :
W = number of words typed in first letter + t
W = 200 + t
Choosing any pair of values from the table :
W = 245 ; t = 45
W = 200 + 45
W = 245
Therefore, the number of words, W typed today can be represented as
W = 200 + t
The domain and range of a function is the set of input and output values, the function can take.
<em />
From the question, we have:
<u>The domain</u>
He cannot mow more than 6 yards a day.
This means that the domain is: 0 to 6
<em>This is properly represented as: [0,6]</em>
<u></u>
<u>The range</u>
When he mows 0 yards, his earnings is:
When he mows 6 yards, his earnings is:
This means that the range is: 0 to 90
<em>This is properly represented as: [0,90]</em>
