Find a polynomial f (x) of degree 3 with real coefficients and the following zeros. -3, 1+2i
f(x) =
x
?

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

i honestly dont know
