1) week 2 she spent $29.21
You would multiply the gallons of gas she bought by the price of each gallon.
2) $1.06 more because you would subtract week 1’s by week 4’s total
I say the answer is point c from the way the points are on the graph
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
