Answer: The factor form of the function F(x) is
, where
gives two complex roots.
Explanation:
The given function is,

According to the rational root theorem 1 and -1 are the possible roots of each polynomial.
Put x=-1

Since the value of F(x) is 0 at x=-1 therefore the -1 is a root of given polynomial and (x+1) is a factor of F(x).
Use synthetic division method to divide the polynomial by (x+1).
The last row of the synthetic division shows the coefficient of remaining polynomial.

At x=2 the value of F(x) is 0, therefore (x-2) is a factor of F(x).
Use synthetic division method to divide the polynomial by (x-2).

Therefore the roots of F(x) are,


Where
factors with real root and
are factors with complex roots.
Multiply 2 by 7, which is 14, and add it to the 4 in the numerator. The fraction becomes 18/7
Hi! Sorry, it would've taken too long to type out, so I wrote it and have the attachment. Good luck!
Use dot product
a=(x1,y1) and b=(x2,y2)
a.b=/a/*/b/ cos x
a.b mean dot product of two vectors
a.b is equals x1*y1+x2*y2
Answer:
800 miles
Step-by-step explanation:
Set up an equation, where x is the number of miles driven:
0.10x + 120 = 200
Then, solve for x:
0.10x = 80
x = 800
So, the maximum number of miles he can drive is 800 miles
