This condition must be observed for the case of a quadratic equation with equal roots:




Answer:
Step-by-step explanation:
Original 873 New 781
The new went down by about 10.5%
873*10.5%= 91.67
873-91.67= 781.33
It decreased 10.5%
Answer:
566,880
Step-by-step explanation:
First you have to understand what the problem is asking you. It wants you to find the difference between working for 40 years with a master's degree and 40 years with a bachelor's degree.
Next you need to do the math. You can use a calculator since these are pretty large numbers. Enter in the following to find how much you make working 40 years with a bachelor's degree: 68,103 * 40 Once you have calculated that, you should get 2,724,120. Now you need to find how much you earn working 40 years with a master's degree. Enter the following: 82,275 * 40 You should get 3,291,000.
Finally you need to find the difference. Type into your calculator the following: 3,291,000 - 2,724,120 You should end up with 566,880.
Hope this helps!

Answer:
Step-by-step explanation:
Answer:
1) The graph is linear, because it has an upwards slope of 5, we can tell because 3*5 =15 and 6*5=30.
2)Real world meaning is the delta change. Hence in this case it's the increase in rain over time. More rain or raining harder as time progresses.
3)It is not linear because the second sample shows a slope of 7.5 meanwhile the third sample shows a slope of 6 which allows us to conclude that it is not linear.
4)The y intercept means the total rain that was present at the start of the recording which essentially means there was no rain when she started the experiment.
