Answer:
Example a) the resulting vector is 54 degrees with a force of 48N (4.8cm)
Example b) the resulting vector is 168 degrees with a force of 38N
Example c) the resulting vector is 129 degrees with a force of 57N
Step-by-step explanation:
i had the same assignment so i used the vector calculator online
You must have the distances mixed up when you typed it because it does not work out equation-wise the way you have it. The distance comes out negative, and distance NEVER should come out negative. If you switch the distances traveled you get that the passenger train is going 60 and the freight train is going 40, which makes sense because if the passenger train is going 60 and the freight train is going 40 which is the 20 mph difference we were told exists between the 2 trains.
Answer:
3400
Step-by-step explanation:
25000
- 7000 x .10= 700 calculate 10% tax
——————
=18000 x .15 =2700 calculate tax over 7000 at 15%
total tax. = 3400
Answer:
x = -17/26
Step-by-step explanation:
4(7x - 1) = 3(2x + 1) - 4(x + 6)
distribute 4 through the parentheses (do 3 and -4 as well)
28x-4=6x+3-4x-24
collect like terms
28x-4=2x+3-24 --> 28x-4=2x-21
move the variable
28x-2x-4=-21
collect like terms
26x=-21+4 --> 26x=-17
then divide
hope this helps and makes sense! :)
