Answer: Relative error = 50%
Step-by-step explanation:
Relative error Re = Absolute error/True value × 100%
True value = 2 scoops
Measured(used) value = 3 scoops
Absolute error Ae = measured(used) value - True value
= 3 scoops - 2 scoops
Ae = 1 scoop
Re = 1/2 × 100%
Re = 50%
Answer:
Hyperbola
Step-by-step explanation:

Lets write variables in square form using completing the square method
LEts group x and y terms

y^2 terms should be positive always, so we pull out negative sign from y^2

We have negative sign in the middle. so we will get equation in the form of

If we have negative sign in the middle then it is an hyperbola
