Akira estimated that a tree was 40 years old. the true age of the tree was 47 years old.
which expression can be used to calculate the percent error in akira’s estimate?

The formula for percent error is : .

So let's plug the given values in the formula.



The percent error is 14.8%

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
