Dividing polynomials. Aka the worst math subject ever<br><br> (X^3+729) / (x+8)
Deffense [45]

Answer:

x^2 - 8x + 64 remainder 217 or you could write it as

(x^2 - 8x + 64)+ 217/(x + 8)

Step-by-step explanation:

You first need to write the polynomial in descending order of degree with zero coefficients for x^2 and x terms, so here we have:

x^3 + 729  =   x^3 + 0x^2 + 0x + 729

So dividing by x+8:-

          x^2 - 8x + 64    <----------the quotient.

x + 8 ) x^3 + 0x^2 + 0x + 729

          x^3 + 8x^2

                 - 8x^2 + 0x

                 -8x^2 - 64x

                              64x + 729

                               64x + 512

                                          217 = Remainder.

lord [1]

Answer:

The answer is "(27.030,29.770)"

Step-by-step explanation:

(\bar{x}) = 28.4

(n)= 49

(\sigma) = 6

(CI) = \bar{x}\pm z^*_{\frac{\alpha}{2}} \frac{\sigma}{\sqrt{n}}

z^*_{\frac{\alpha}{2}}\ for \ 89\%\ confidence = 1.598 \\\\\text{Using z table }\\\\ NORM.S.INV(1-\frac{(1-0.89)}{2})

CI = 28.4 \pm 1.598 \times  \frac{6}{\sqrt{49}}=(27.030,29.770)
