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

Answers

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:

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

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

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

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

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

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

what is x?

Answers

$-4x+15=-13 \ \ \ |-15 \n \n -4x=-28 \ \ \ |:(-4) \n \n x=7$

==================================

"Associate with people who are likely to improve you."

solve your equation step-by-step.

−4x+15=−13

Subtract 15 from both sides.

−4x+15−15=−13−15

−4x=−28

Divide both sides by -4.

−4x/−4 = −28/−4

A student made a model of a building. The model was 3 feet high and 12 feet wide. The building is 720 feet wide. Which proportion correctly show how to find the height of the building?

Answers

Ok, so what we do is simply divide 720 by 12
720/12=60 next you just multiply whatever part of the building by 60 in order to get a correct proportion in this case we are doing 60*3=180 and the answer is the height of the building must be 180 feet.
