There are many polynomials that fit the bill,
f(x)=a(x-r1)(x-r2)(x-r3)(x-r4) where a is any real number not equal to zero.
A simple one is when a=1.
where r1,r2,r3,r4 are the roots of the 4th degree polynomial.
Also note that for a polynomial with *real* coefficients, complex roots *always* come in conjugages, i.e. in the form a±bi [±=+/-]
So a polynomial would be:
f(x)=(x-(-4-5i))(x-(-4+5i))(x--2)(x--2)
or, simplifying
f(x)=(x+4+5i)(x+4-5i)(x+2)^2
=x^4+12x^3+77x^2+196x+164 [if you decide to expand]
The line would be called the median. The definition of '<span>A line connecting a vertex of a scalene triangle with the midpoint of the opposite side' pertains to the median. There are three medians that connect the scalene triangle. </span>
x would equal 14 hope this helps
To analyze the problem first is to arrange the equations according to their uses:
# of taxi accident y = -143.3X^2+1823.3x+6820
# of injuries y = -416.72X^2+4416.7x+8500
So the answer if X = 9 will be represented by 1999
# of taxi accident y = 11622.4
# of injuries y = 14495.98
I hope you understand the answer and feel free to ask for more.
