Answer:
You can see below!
Step-by-step explanation:
Basically, a protractor is used to measure angles. You probably have a semi-circle shaped one. Looking at the bottom middle of the protractor should show you lines intersecting each other at a point. If you have an angle on a piece of paper, place that point on the ends of the line segments making up the angle. Then, check where each line of the angle crosses the numbers on the outer rim. That shows you the measure of the angle you are examining. It can be a bit tricky, but with practice you'll get it in no time!
You go down to the negative number x is first and then you go to the positive number which is y
Hello,
Let's assume x the time the express runs.
56*x=35*(1.5+x)
==>21x=52.5
==>x=2.5 h =2 h 30 min
Picking up 8 boxcars after 5 stops makes a total of 40 new boxcars . . . add the original 3 engines, 52 boxcars, and 1 caboose to get a total of . . . 3 + 52 + 1 + 8 + 8 + 8 + 8 + 8 = 96 total cars
Answer:
The circulation of the given vector is (5/2)x² + 7yz + 6yz + C
Step-by-step explanation:
Given that F = 5xi + 7zj + 6yk
The circulation of F is given as
Integral of F.dr
dr = idx + jdy + kdz
F.dr = (5xi + 7zj + 6yk).(idx + jdy + kdz)
= 5xdx + 7zdy + 6ydz
Integral of F.dr = Integral of (5xdx + 7zdy + 6ydz)
= (5/2)x² + 7yz + 6yz + C
