Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign. The given option the option A matches correctly with the above polynomial equation which is,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

Hence the option A is the correct option.

<h3>Given information-</h3>

The given polynomial equation in the problem is,

$8x^2y^2-\dfrac{3x^3y}{2}+4x^4-7xy^3$

<h3>Polynomial equation </h3>

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign.

In the above polynomial equation the variable are<em> x </em>and <em>y </em>and the highest power of the variable <em>x</em> is four and highest power of the variable <em>y</em> is three.

Arrange the polynomial equation in the power of the variable <em>x. </em>Thus,

$4x^4-\dfrac{3x^3y}{2}+8x^2y^2-7xy^3$

Arrange the polynomial equation in the power of the variable <em>y. </em>Thus,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

From the given option the option A matches correctly with the above polynomial equation which is,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

Thus the option A is the correct option.

7. The bottom of a river makes a V-shape that can be modeled with the absolute value function,

hjlf

Answer:

If one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480

Step-by-step explanation:

Given that:

The absolute value function:

$d(h) = \dfrac{1}{6}|h - 300| - 50$

To calculate the position of the buoy where the river bottom is 20 feet below the surface, we equate the absolute value function to the negative value of 20 feet and then solve it for h.

d(h) = -20

$d(h) = \dfrac{1}{6}|h - 300| - 50 = -20$

Let us add the sum of 50 on both sides, then:

$= \dfrac{1}{6}|h - 300| - 50+50 = -20+50$

$= \dfrac{1}{6}|h - 300| = 30$

By multiplying 6 on both sides, we have:

|h - 300| = 30 (6)

|h - 300| = 180

We can attempt the above expression by rewriting it as two equations:

h - 300 = 180 or h - 300 = - 180

Let us add 300 to both sides from the two expressions above:

h - 300 + 300 = 180 + 300 or h - 300 + 300 = -180 + 300

h = 480 or h = 120

Thus, if one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480
