Answer:
.001
Step-by-step explanation:
You see it is the same numbers just it was moved 3 places to the left.
So the you would multiply it by .001 <------ there are 3 decimal places.
When you multiply them you get.
647.6*.001= .6476
Convert to degrees
34°18' is the same as 34° 18' 0"
34° 18' 0" = 34° + 18'/60 + 0"/3600
= 34.3°
putting tan(34.3) into a calculator in degree mode
tan ( 34°18' )= tan(34.3) = 0.6822
Equation format for a slope, m and a point (x1, y1)
y - y1 = m(x - x1) (Try and memorize this formula)
8) for (3,-4), m = 6. x1 = 3, y1 = -4, Substituting
y - y1 = m(x - x1)
y - (-4) = 6(x - 3)
y + 4 = 6x - 18
y = 6x - 18 - 4
y = 6x - 22
10) for (-2,-7), m = 4/5. x1 = -2, y1 = -7, Substituting
y - y1 = m(x - x1)
y - (-7) = (4/5)*(x - (-2))
y + 7 = (4/5) *(x +2) 4/5 = 0.8
y + 7 = 0.8x + 1.6
y = 0.8x + 1.6-7
y = 0.8x - 6.4
y = (4/5)x - (64/10)
y = (4/5)x - (32/5)
So same approach to solve others. Cheers.
