Roger has a nail that is 12 centimeters long. he measures and records the length of the nail as 15 centimeters. what is the percent error in rogers measurements?

 25%

Step-by-step explanation:

Given : Roger has a nail that is 12 centimeters long.

He measures and records the length of the nail as 15 centimeters.

i.e. Estimated length = 15 cm and Actual length = 12 cm

The percent error in Rogers measurements is given by :-

Hence, the percent error in Rogers measurements is 25%.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
