Explanation:
It is given that Bev earns $2 a week.
Thus, for n number of weeks, we shall multiply $2 with n.
Where is the number of weeks.
For 1 week, Bev earns ⇒ $2
For 2 weeks, Bev earns ⇒ $4
For 3 weeks, Bev earns ⇒ $6
For 4 weeks, Bev earns ⇒ $8
Thus, we can see that the domain is the number of weeks.
Hence, Domain :
Also, the money earned is the range.
Hence, Range:
Answer:
The answer is
Step-by-step explanation:
when writing scientific notation, there must be one number to the left of the decimal point.
To achieve this in this problem, you need to move the decimal point 3 times to the right.
because you are moving the point to the right, the exponent will be negative.
*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*
therefore you answer should be written as:
