True....THAT is the definition of perpindicular
Angle 1 and agle 4 form a straight line ....they add to 180 degrees...so you should be able to calculate angle 4

4 cuts will make 5 slice- pieces of cake
then 5 cuts across those 5 peices will make 30 pieces.... soooo 9 cuts?
9:00 to 12:20 is 3 1/3 hours
3 1/3 hr x 150 m/hr = 500 mi
at 7 y/o he hadd 22 coins He added (577-22) = 555 coins over the years
7 yrs + 555 coins/15 coins/yr = 7 + 37 yrs = 44 y/o
A = aldo
C = Carlos = 3A
K = Karen = A + 8 Summed they equal 93
A + 3A + A+8 = 93 Solve for A = Aldo then Carlos = 3 * Aldo and Karen = Aldo + 8
Sine wave amplitude = 2 and inverted (flipped around x-axis) due to the ' - ' sign......looks OK to me !
I think you are correct....it does work against the force of FRICTION, but does not move it vertically agains the force of gravity....
You can pick either of the equations....just put in -3 where 'y' is to find x
x + 2(-3) = -4
2x-3y=13
x+2y=-4 Multiply THIS equation by -2
-2x-4y=8 add this to TOP equation
-7y = 21
y = -3 now substitue this 'y' value back into one of the equations to find the 'x' value of the coordinate
