Answer:
3.44 cm
Step-by-step explanation:
When the pendulum is at its lowest point, the vertical length of the pendulum is L.
When the pendulum is at its highest point, the vertical length of the pendulum is L cos θ.
So the height difference of the pendulum between its lowest and highest points is h = L − L cos θ.
The pendulum swings 72° from right to left, or 36° from the vertical.
The length of the pendulum is 18 cm.
So the height is:
h = L − L cos θ
h = 18 − 18 cos 36°
h = 3.44
Answer:
subtract 24 and 15 and you get 9
Answer:
$5.61
Step-by-step explanation:
Subtract the amount spent by the amount given to the cashier.
$20 - $14.39 = $5.61
In 6300 it is 300 or hundreds, in 530 it is 30 or tens.
The slope of AB is also -5. This is because parallel lines have equal slopes.
