Answer:
A) The model exists: f(x) = -3x^2 +4x -4
Step-by-step explanation:
A quadratic model will always exist for 3 given points, provided they are not on a line. In that case, a linear model is appropriate.
Here, the slope between -1 and 0 is positive, and the slope between 0 and 3 is negative. Thus, we know these points are not collinear, and a model must exist.
The model is most easily found using a quadratic regression tool. Such is shown in the attachment. It tells us that ...
f(x) = -3x^2 +4x -4
A. 8 pages per hour because 120 (2 hours) ÷15=8
b. $40÷15 (pages)=$2.70 (rounded)
Answer:
1.568, 3.432, 11.568, 13.432
Step-by-step explanation:
Divide equation
by 6:

Then


Since
four smallest positive solutions are
1. 
2. 
3. 
4. 
Yes, yes, yes, yes all of them are yes hope this helps also not a genius so be careful with the answers
The answer is 2. I say that because 3 times 2 is 6, but if you wanted to do 3 thirds, you'd need 9 pieces.
