Write the polynomial in standard form. Then name the polynomial based on its degree and number of

Triss [41]

Answer:

$15y^9 - 7y^3 + y$

Nonic polynomial

Step-by-step explanation:

Given

$y - 7y^3 + 15y^9$

Required

Write in standard form

The standard form of a polynomial is:

$ay^n + by^{n-1} + ......... + k$

So, we have:

$y - 7y^3 + 15y^9$

The standard form is:

$15y^9 - 7y^3 + y$

And the name is: Nonic polynomial (because it has a degree of 9)

There are 16 squares and 4 circles. What is the simplest ratio of circles to squares?

Mashcka [7]

4x-2x=80-20

2x=60

x=30
