I think this is how you're supposed to do it
20,000/120 = 166.66666666666667 m/s
Use the law of sines....(sina/A=sinb/B=sinc/C for any triangle)
What that means is the sine of an angle divided by the length of the side opposite the angle is a ratio that is true each angle/side pair...In this case:
sin90/122=sinc/22 rearrange to solve for sinc
sinc=(22sin90)/122 now take the arcsin to solve for c
c=arcsin[(22sin90)/122]
c≈10.388857815469611987441020361405
c≈10.39° (to nearest hundredth of a degree)
Learn this :
VUX -- vertical line, undefined slope, represented by x = a number
HOY -- horizontal line, 0 slope, represented by y = a number
ok....so u need the equation for a vertical line passing thru (-5,-1)...
a vertical line is represented by x = a number.....and that number will be the x value of ur points.
Therefore, ur equation is : x = -5 <==
**just so u know, if u were needing a horizontal line going thru the same points, ...and a horizontal line is represented by y = a number...with the number being the y value of ur points....the equation would be y = -1
First we swap our x and y variable, so we get
x = 3y + 2
Then, we solve for y
We can first subtract 2 on both sides
x - 2 = 3y
Then we can divide by 3 on both sides to get
x/3 - 2/3 = y
So our final equation is
y = x/3 - 2/3
Solution:
Rewriting input as fractions if necessary:
1/10, 3/4, 1/2
For the denominators (10, 4, 2) the least common multiple (LCM) is 20.
Therefore, the least common denominator (LCD) is 20.
