Answer:
tax: $18.9
total cost: $333.9
Step-by-step explanation:
$315 × 0.06 = 18.9
18.9 + 315 = 333.9
btw you can also do "315 × 1.06" to get the total cost without having to manually add the tax
Answer:
the approximate range of change is 150 for 3
the approximate range of change is 1600 for 4
between 1970 and 1975
please give me brainlest
For this case we have a direct variation of the form:
Where,
- <em>k: proportionality constant
</em>
We must find the value of k.
For this, we use the following data:
Therefore, replacing values we have:
Rewriting:
Clearing the value of k we have:
Therefore, the direct variation equation is given by:
Answer:
The quadratic variation equation for the relatonship is:
By definition, we have that the average rate of change is given by:
Substituting values we have:
Rewriting we have:
Therefore, the graph that has an AVR of 1/2 is the graph of the linear function.
Answer:
graph shows a rate of change of 1/2 is the linear function
