4 trillion pounds.
1 gigawatt-hour is equal to 1,000,000 kilowatt-hours.
Out of our 4,000,000 gigawatt-hours, 50% of it comes from coal; this is 2,000,000 gigawatt-hours.
2,000,000(1,000,000) = 2,000,000,000,000 (2 trillion) kilowatt-hours.
Since each kilowatt-hour is 2 lbs of carbon dioxide, 2 trillion * 2 = 4 trillion lbs of carbon dioxide.

Use a calculator it will help.
Answer:
They are equal since they are both 90 degree angles.
Step-by-step explanation: Please brainliest? (Sorry if not correct.)
To determine the maximum height, h, from the given above. Differentiate the function and equate to zero. Then, determine the value of t. The value, when substituted to the original function, will give the maximum height. For this given,
dh(t)/dt = -32t + 128 = 0, t = 4
Substituting t = 4 to the original function gives 320. Thus, the maximum height is 320 units.
