Answer:
-189.8 J
Step-by-step explanation:
We are given that f
Force applied=F=35 Ni-37 Nj
Displacement, s=(-8.7m)i-(3.1m)j
We have to find the work done .
We know that
Work done=
Using the formula
Work done=
Work done=
Using 
Work done=-189.8J
Hence, the work done =-189.8 J
1. C. Concave pentagon
2. A. 1620°
b/c (11 - 2) × 180 = 1620
3. B. 165°
b/c (24 - 2) × 180 ÷ 24 = 165
4. A. 160°
b/c (18 - 2) × 180 ÷ 18 = 160
Answer:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.
Step-by-step explanation: hope this helps ^^
Step-by-step explanation:
Recall the Ratio for tan
Tan(theta) = opposite / adjacent
Tan (x) = 9 / 5
solve for x (use Tan^-1(...) )
