5 0

Answer:Solving the quadratic equation, the coordinates of the roots are: (-1,0) and (-3,0)

The quadratic equation given is:

Which has coefficients .

Now, we find the solutions:

 

The coordinates of the roots are  and , as a root is a value of x when y = 0, thus, in the problem, (-1,0) and (-3,0).

How can you visit the sun without burning up worksheet answer key
Lesechka [4]

How can you visit the sun without burning up worksheet answer key is a heading for a worksheet that involves mathematical questions to calculate. The attached file displays those mathematical questions.

Before that, the sun is known as a star that is located in the middle of the Solar system. It is a virtually flawless sphere of hot plasma that has been heated by nuclear fusion processes in its center, thereby radiating energy as infrared radiation and ultraviolet light.

It is nearly impossible to visit the sun due to the degree of its temperature and radiation.

  • From the image attached below which depicts the heading to the question, we have:

a) 5(x - 9) = 2x + 15

Open brackets

5x - 45 = 2x + 15

Collect like terms

5x - 2x = 45 + 15

3x = 60

x = 60/3

x = 20

b) \mathbf{ 7n - 20 = 9(4n + 1)}

Open brackets

7n - 20 = 36n + 9

7n - 36n = 20 + 9

- 29 n = 29

n = - 29/29

n = - 1

Therefore, from the given information, we can conclude that It is nearly impossible to visit the sun due to the degree of its temperature and radiation. Also, the value of x = 20 and the value of n = -1

Which scenario describes intraspecific, indirect competition?
GenaCL600 [577]

The correct answer is - C. A male black bear eats fish in an area of a lake, so other black bears can't.

The intraspecific competition is a competition between the members of the same species for resources and territory. The indirect competition, in this case, would mean that the members from the same species do not get into a direct physical confrontation over the resources, but instead avoid each other and once one member occupies one place, the other one goes to another space that is not occupied.

In this case, with the black bear, the bear has occupied a spot at the lake where it feeds itself. Even though it is using the food resources, the other bears don't physically confront it, but instead pick another place on the lake that is free for using the same food resources.
