Use the rational zero theorem
In rational zero theorem, the rational zeros of the form +-p/q
where p is the factors of constant
and q is the factors of leading coefficient
In our f(x), constant is 2 and leading coefficient is 14
Factors of 2 are 1, 2
Factors of 14 are 1,2, 7, 14
Rational zeros of the form +-p/q are
Now we separate the factors
We ignore the zeros that are repeating
Option A is correct
Step-by-step explanation:
the first derivative by using
f’(x)=xn = nx^(n−1)
f(g(x)) = f’(g(x))g’(x)
So f’(x)=2(x⅔ -1)*(2/3 x^(-1/3))=
Second derivative by using:
h’(x)=f(x)*g(x)=f(x) g’(x) + f’(x) g(x)
f’’(x)=
They are asking for the difference between the 2 cities so all you need to do is subtract. (143-107=36)
Answer:
=4.15n + 2.98
Step-by-step explanation:
Answer:
a)
b)
Step-by-step explanation:
We assume that the data is this one:
x: 150 129 142 112 134 122 126 120
y: 88 96 106 80 98 63 95 64
Part a
We want to find a linear model . Where:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Part b
For this case w ejust need to replace x= 113 in the regression model and we got this:
