Answer:
a) rounded to the ones place and 2 significant figures.
b) rounded to tenths place and 1 significant figure.
Step-by-step explanation:
Significant figures are the number of needed place values for accuracy. Round each number according to the least number of significant figures within the problem.
A. 9 cm+2.8 cm = 11.8 cm rounds to 12 which has 2 significant figures. Round to the ones place value since 9 has the least number of significant figures.
B. 0.135 atm+0.6 atm = 0.735 atm rounds to 0.7 atm which has 1 significant figure. Zero preceding the value is not considered significant. Round to the tenths place value since 0.6 has the least number of significant figures.
Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°
Answer:
[24, 375]
Step-by-step explanation:
f(2) = 24
f(5) = 375
f(x) is increasing in the given domain so the range is simply given by the extremes.
