Answer:
Step-by-step explanation:
X=-x^2+x-5
A mixed number is a combination of a whole number and a fraction. The fraction 9/2 is equal to 4.5. So you would have to find a mixed number in between 4.5 and 5. You could do this by turning 5 into a mixed number, which would be 10/2.
So now you have to find a mixed number in between 9/2 and 10/2. The best way to do this is multiply both numbers so that you can get a wider range of numbers. You would not be changing the end result, you would only be changing the size of the fraction.
I would multiply both mixed numbers by 2, which would get you 18/4 and 20/4. That would mean that a number in between these two mixed numbers is 19/4. (which would simplify to 4.75)
Answer:
Step-by-step explanation:
You have no grounds for making a statement like that. There are a variety of reasons why you might not get immediate answers. Be patient.
I will do the second part of this question (finding the first three numbers):
a(4) = a(3)*(-3) + 2 = -148, so a(3)*(-3) = -150 and a(3) = -50
a(3) = 50
a(2) = a(3)*(-3) + 2 = 50, so -3*a(3) = 48 and a(d) = -16
a(1) = a(2)*(-3) + 2 = -16, so a(2)*(-3) = -18 and a(1) = 6
The procedure for finding a(5), a(6) and a(7) is exactly the same.
X= 23/7 so twenty-three sevenths
