Answer:

y^3/(27 x^3)

Step-by-step explanation:

Simplify the following:

((3 x)/y)^(-3)

((3 x)/y)^(-3) = (y/(3 x))^3:

(y/(3 x))^3

Multiply each exponent in y/(3 x) by 3:

(y^3)/((3 x)^3)

Multiply each exponent in 3 x by 3:

y^3/(3^3 x^3)

3^3 = 3×3^2:

y^3/(3×3^2 x^3)

3^2 = 9:

y^3/(3×9 x^3)

3×9 = 27:

Answer: y^3/(27 x^3)

WILL MARK BRAINLIEST!!!PLZ HELP!!!

Answer:

Step-by-step explanation:

Hello,

"Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only."

We know that Kelsey is right, a polynomial of degree 3 has maximum 3 zeroes, so it means that the graph of this polynomial has maximum 3 x-intercepts.

So how Ray can be right too?

we need to think of y-intercept, if we add the y-intercept then Ray can be right too,

as you can see in one example below

there are 3 x-intercepts and 1 y-intercept.

This being said, Ray is not always right. For instance $x^3$

has only 1 zero (multiplicity 3) its graph has only 1 intercept in the point (0,0)

hope this helps

The pitch of a roof is its slope. The roof of a home rises vertically a distance of 8 ft through a horizontal distance of 15 ft.

PIT_PIT [208]

If we discuss this as if it is a triangle then the "rise" is the vertical side and the "run" is the adjacent side.
So the ratio of the rise to the run is 8 / 15 which equals 0.5333333333 
To find the angle of this roof pitch we look up the arc tangent of 0.5333333333 and we find that is 28.072 Degrees
