Which of the position versus time graphs below matches the following description: a speed versus time graph has a horizontal line at 0 m/s from zero to five seconds? A Position versus Time graph is shown with y-axis labeled position in meters up to 15 and x-axis labeled time in seconds up to 5. The points plotted are 0, 10 and 1, 10 and 2, 10, and 3, 10, and 4, 10, and 5, 10. A horizontal line connects the points.

A Position versus Time graph is shown with y-axis labeled position in meters up to 15 and x-axis labeled time in seconds up to 6. The points plotted are 0, 0 and 1, 5 and 2, 10, and 3, 10, and 4, 10, and 5, 5, and 6, 0. Three straight lines connect the points.

A Position versus Time graph is shown with y-axis labeled position in meters up to 30 and x-axis labeled time in seconds up to 5. The points plotted are 0, 0 and 1, 5 and 2, 10, and 3, 15, and 4, 20, and 5, 25. A straight line connects the points.

Please help!!

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )

agree
