Choose the correct classification of 5x + 3x2 − 7x3 + 2.a. Third degree polynomial
b. Fourth degree trinomial
c. Sixth degree polynomial
d. First degree binomial

Answers

Answer 1
Answer: The highest power of x is 3, so this is a third degree multi-term expression, or polynomial. Thus, the answer is A.
Answer 2
Answer:

Answer: a. Third degree polynomial

Step-to-step explanation:-

  • The degree of a polynomial is the highest degree of its individual terms with coefficients not equals to zero.

Given polynomial : 5x+3x^2-7x^3+2

We can see that the highest degree of x in the given polynomial is 3.

Therefore, the given polynomial 5x+3x^2-7x^3+2 is classified as a third degree polynomial.

Which area of the earth's crust would be expected to be thickest?under the Atlantic ocean
in the Rocky Mountains
under the Missouri River
inside the Grand Canyon

Answers

The thickest part of the earth’s crust is under mountains. Whenever there is a volcanic eruption, more material is poured out on the earth’s surface from under the crust, so as the years pass the earth’s crust is increasing slowly.

In one paragraph, explain how matter such as water, nitrogen, oxygen, and carbon dioxide cycles in an ecosystem.

Answers

Energy changes forms as it moves through an ecosystem, but no new energy is produced. As a result, energy and matter are preserved throughout all ecosystem processes.

How do the ecosystem cycles water carbon and nitrogen impact life within the ecosystem?

The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. When these three cycles are in harmony, they remove waste from the ecosystem and replenish it with the nutrients it needs to support life.

What is an ecosystem's cycle of matter?

As these organisms live and die, matter circulates between the air and soil, as well as among plants, animals, and microbes. In addition to absorbing gases and water from the environment, organisms also emit waste materials back into it.
