How many roots of the polynomial 30x^4 + 7x^3-125x^2-54x+72 have absolute value greater than 1?

Daniel [21]

Answer:

There are 3 roots of the given polynomial that have absolute value greater than 1.

Step-by-step explanation:

We are given the polynomial:

$p(x) = 30x^4 + 7x^3-125x^2-54x+72$

We can factorize the given polynomial as:

$p(x) = 30x^4 + 7x^3-125x^2-54x+72\\=(x-2)(2x+3)(5x-3)(3x+4)=0$

$\text{Solving for}\\(x-2) = 0\\x = 2\\|x| = 2 > 1$

$\text{Solving for}\\(2x+3) = 0\\x = \dfrac{-3}{2}\\\bigg|\dfrac{-3}{2}\bigg| = \dfrac{3}{2} > 1$

$\text{Solving for}\\(5x-3) = 0\\x = \dfrac{3}{5}\\\bigg|\dfrac{3}{5}\bigg| = \dfrac{3}{5} < 1$

$\text{Solving for}\\(3x+4) = 0\\x = \dfrac{-4}{3}\\\bigg|\dfrac{-4}{3}\bigg| = \dfrac{4}{3} > 1$

Thus, there are 3 roots of the given polynomial that have absolute value greater than 1.

Answer:

m = 3

Step-by-step explanation:

<u>Assuming these shapes are similar, you can set up a proportion:</u>

<u /> $\frac{8}{12} =\frac{2}{m}$

<u>→Cross multiply:</u>

<u /> $\frac{8m}{24}$

<u>→Divide 24 by 8:</u>

m = 3

madreJ [45]

Answer:

The resulting residual value is e=-40.24.

Step-by-step explanation:

The residual value e for a regression model is defined as the difference between the real value y and the predicted value yp:

$e=y-y_p$

The predicted value for DISTANCE=0.43 miles is:

$RENT = 1200.4326 - 256.2567\cdot DISTANCE\\\\RENT(0.43) = 1200.4326 - 256.2567\cdot 0.43\\\\RENT(0.43) = 1200.4326 - 110.1904=1090.2422\\\\$

Then, if the real value is $1,050, the residual value is calculated as:

$e=y-y_p\\\\e=1050-1090.2422=-40.2422$
