Find an nth degree polynomial function with real coefficients satisfying the given conditions.

damaskus [11]

Step-by-step explanation:

Our roots are 3, and i so our roots form

will be

$(x - 3)(x - i)$

Since i is one root, it conjugate, must be the other.

so we have

$(x - 3)(x - i)(x + i)$

Simplify

$( {x}^{2} + 1)(x - 3)$

${x}^{3} - 3 {x}^{2} + x - 3$

So the function is

$x {}^{3} - 3 {x}^{2} + x - 3$

Martha Alison and Scott buy 3.8 pounds of clay Martha used 1 /4 of the clay for a sculpture Scott used 2/5 of the remaining amou

Sever21 [200]

They are left with 0.51 pounds of clay.

Step-by-step explanation:

Given,

Amount of clay bought = 3.8 pounds

Amount used by Martha = $\frac{1}{4}\ of\ clay$

Amount used by Martha = $\frac{1}{4}*3.8=0.95\ pounds$

Amount left after Martha's use= Total amount - amount used by Martha

Amount left = 3.8 - 0.95 = 2.85 pounds

Amount used by Scott = $\frac{2}{5}\ of\ amount\ left$

Amount used by Scott = $\frac{2}{5}*2.85=\frac{5.70}{5}$

Amount used by Scott = 1.14 pounds

Amount left after Scott's use = Amount left after Martha's - Amount used by Scott

Amount left after Scott's use = 2.85 - 1.14 = 1.71 pounds

Amount used by Alison = 1.2 pounds

Amount left = Amount left after Scott's use - Amount used by Alison

Amount left = 1.71 - 1.2 = 0.51 pounds

They are left with 0.51 pounds of clay.
