Answer:

x^3-4x^2+25x-100

Step-by-step explanation:

We have 2 roots -5i and 4. Using the conjugate root theorem for the root -5i, we know that 5i should be another root

Combining the roots into a polynomial gives us:

(x+5i)(x-5i)(x-4)

Expand:

(x^2 + 25)(x-4)

x^3-4x^2+25x-100

n a science experiment, farah mixed a salt solution and vinegar in the ratio 3 : 7.

A.) if she used 262.8 milliliters of salt solution, the amount of vinegar is equal to:

X = 262.8 ml ( 7 ml vinegar/ 3 ml salt soln)

X = 613.2 ml vinergar

B.) y = 0.56 L vinegar ( 3 L salt soln/ 7 L vinegar)

Y = 0.24 L salt soln
