Write a polynomial function with rational coefficients so that P(x) = 0 has the given roots. 4, 16, and 1 + 9i
bulgar [2K]
I remember dis, yey

so if a polynomial has roots r_1, r_2, r_3, it can be factored into
f(x)=a(x-r_1)^b(x-r_2)^c(x-r_3)^d where a,b,c,d are constants

also, if a polynomial has rational coefients and a+bi is a root, then a-bi must also be a root


so our roots we need are
4,16, 1+9i and 1-9i

so assuming multiplity 1 (that means we have something like [/tex]f(x)=a(x-r_1)^1(x-r_2)^1(x-r_3)^1[/tex])

we get that your function is
P(x)=(x-4)(x-16)(x-(1+9i))(x-(1-9i)) which simplifies to
P(x)=(x-4)(x-16)(x-1-9i)(x-1+9i) which expands to
P(x)=x^4-22x^3+186x^2-1768x+5248

Convert 17⁄8 to a decimal, rounded to the nearest hundredth. A. 2.13 B. 2.44 C. 1.78 D. 1.14
11111nata11111 [884]
Hey there! :)

All you have to do is divide the numerator(top number) by the denominator(bottom number).

17 ÷ 8 = 2.125

Rounded to the nearest hundredth = 2 places after the decimal point.

After the 2 is a 5. If it's 5 or greater, you move it up by 1.

2 + 1 = 3

2.125 = 2.13

Your answer is A ⇒ 2.13

Hope this helps :)
