Answer:
The percent error of the measurement, to the nearest tenth of a percent is 
Step-by-step explanation:
Estimated length of a line = 12.4 inches
Actual length of the line = 15.7 inches
Error = 15.7 - 12.4 = 3.3 inches
Percent error of the measurement  ≈ 21.0
 ≈ 21.0
So, the percent error of the measurement, to the nearest tenth of a percent is

Answer:
a4 = 128
a5 = -512
Step-by-step explanation:
a1= -2
q= (-1)^(n+1) × 4
a4 = a1q³ = (-2) (-4)³ = -2 × -64 = +128
a5 = a1q⁴ = (-2) (-4)⁴ = -2 × 256 = -512
