Answer:
[0,1] and [-1,0]
Step-by-step explanation:
We have the function to determine consecutive values of x between which each real zero is located we have to replace the function with different values and then analyze the results.
We are going to replace the function with x=0,
Now we are going to replace with x=1,
With x=2,
Now with x=-1,
With x=-2,
We have to analyze:
We have that f(2) and f(1) have the same signs both are negatives this means that there isn't a zero between the interval [1,2].
We have that f(1) and f(0) have opposite signs this means that there is a zero between the interval [0,1].
f(0) and f(-1) have opposite signs too, then there's also a zero in the interval [-1,0].
And finally, f(-1) and f(-2) have the same signs then there isn't a zero in the interval [-2,-1]
The graph of the function shows that the answer is correct:
Answer:
19
Step-by-step explanation
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Answer:
Step-by-step explanation:
Find the interest: I=prt. I=2000(.18)(.25). I=360(.25). I=90. Add the interest to how much you previously owed: 2000+90=2090. You now owe $2,090 :)
