Y = -2x + 1
y = -2x + 2
y = -2x + 3
these are all parallel lines because they have the same slopes (-2) but different y intercepts.
y = 3x + 4
y = -1/3x + 3
these are perpendicular lines because they have negative reciprocal slopes.
slope of a line parallel to the x axis : If it is parallel to the x axis, it is a horizontal line and has a slope of 0.
slope of a line perpendicular to the x axis : if it is perpendicular to the x axis, it is a vertical line with a slope that is undefined.
slope of line parallel to the y axis : vertical line, undefined slope
slope of a line perpendicular to the y axis : horizontal line, slope of 0
You can use this formula: <span>vf^2=0+2(9.8)(M)
solve it out like so:
vf^2=0+2(9.8)(180)
vf^2=2(1764)
vf^2=3528
now, square both sides to cancel out the power of 2. you are left with:
about 59.4 m/s</span>
Answer:
applying trigonometry
base= 30inches
height= 50inches
angle between ladder and ground = 59.04°
for the length of the ladder...
sin59.04 = opposite side ÷ hypotenuse
sin59. 04 = 50inches ÷ hypotenuse
0.8575 = 50 inches ÷ hypotenuse
cross multiply;
hypotenuse = 50inches ÷ 0.8575
the length of the ladder = 58.309inches
Answer:
these are the answers you need and you'll need it anyways yw
