William has a 22 ounce coffee. He drinks 2 ounces. Enter the percentage of ounces William has left of his coffee. Round your answer to the nearest hundredth.

Therefore, we conclude that William left 90.9% of an ounce of his coffee.

Step-by-step explanation:

We know that William has a 22 ounce coffee. He drinks 2 ounces. We calculate percentage of ounces William has left of his coffee.  

We get 22-2=20 ounce coffee.

We have the following proportion:

Therefore, we conclude that William left 90.9% of an ounce of his coffee.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
