Answer:
A.
Step-by-step explanation:
The graph of the y-axis would be x=0
Take two points from both functions. You
will find out that both slopes are the same.
Also you can see that the functions have different y-intercepts.
If the functions have the same slope but different y-intercepts they are parallel to each other
I hope this helps
Answer:
A) The maximum error in the calculated surface area:
Relative error:
B) The maximum error in the calculated volume:
Relative error:
Step-by-step explanation:
A) The formula for the surface area is:
The measured value is the circumference which is equal to:
then the radius is:
Substituting in the formula of the surface:
Using the formula to calculate the error:
Where is the variable measured and is a function of ().
We have C=80cm and dC=0.5cm
The relative error is the maximum error divide by the total area. The total area is:
B) The formula for the volume is:
Using
The maximum error is:
The calculated volume is:
The relative error is:
