Answer: area of triangle = 13.4 ft ( after rounding the answer to 3 significance figures)
Step-by-step explanation:
formula for the area of triangle
= S + S + S
= 4.34 + 3.78 + 5.27
= 13.9 ft
= 13.4 ( after rounding off to three significant figures )
Acceleration = (change in speed) / (time for the change) .
Change in speed = (25 m/s - 9 m/s) = 16 m/s
Time for the change = (8 sec - 5 sec) = 3 seconds
Acceleration = (change in speed) / (time for the change)
= (16 m/s) / (3 sec)
= (5 and 1/3) m/s² .
(rounded to the nearest hundredth ... 5.33 m/s² . )
Area is a metric concept that can allow a measurement to be assigned to the extent of a surface, expressed in mathematics as units of measurement called surface units.
