A skydiver's parachute opened at 3000 feet. Thirty seconds later, the skydiver's height was recorded at 2500 feet. What is the rate of change and what does it mean in this situation? A.
503; descending 50 feet every 3 seconds
B.
−503; descending 50 feet every 3 seconds
C.
1003; descending 100 feet every 3 seconds
D.
−1003; descending 100 feet every 3 seconds

I believe its A. I am sorry if i am wrong, but i think thats what it is :)

Step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
