Solve for c.|c- 2| >3
Write a compound inequality like 1 3. Use in tegers, proper
fractions, or improper fractions in simplest form.

Answers

Answer:

To solve the inequality |c-2| > 3, we need to consider two cases:

c-2 > 3

c-2 < -3

For the first case, we add 2 to both sides of the inequality to get:

c > 5

For the second case, we add 2 to both sides of the inequality and multiply by -1 to get:

-c > -1

c < 1

Therefore, the solution to the inequality |c-2| > 3 is:

c < 1 or c > 5

This is a compound inequality that can be written as:

1 < c or c > 5

Which of the following occurs during the ecological succession of an ecosystem?A. An ecosystem reaches a final, unchanging stage.

B. Animals move out of the ecosystem until succession is complete.

C. Living organisms modify their environment a little at a time.

D. Parts of communities split off to form new communities.

Answers

The answer is c. Living organisms modify their environment a little at a time.




The purpose of succession is for an ecosystem to reach balance state right after it is formed or after it is disturbed by man or some disasters. It will increase biodiversity and help to prevent the desertification. Living organisms modify environment a little at a time. By modifying it, they make the environment more suitable for the new species to enter the community.
I think the correct answer from the choices listed above is option C. During an ecological succession of an ecosystem, what happens is that living organisms modify their environment a little at a time in order for them to survive. Hope this answers the question.

A rectangular field is 80 meters wide and 125 meters long.Give the length and width of another rectangular field that has the same perimeter but a smaller area.

Answers

Perimeter of the rectangle is 2*(80+125)=410
The rectangle having the biggest area given the same perimeter is a square. So we need to go "the other way" -- find the rectangle with larger side ratio. 200 m and 5 m is a good example.

The area of the first rectangle: 80 m * 125 m =10000 m^2
The area of the second rectangle : 200 m * 5 m = 1000 m^2 (10 times smaller).

You are using a math software program to make a pattern for a plastic part. You draw the pattern on a coordinate plane with units in millimeters and the bottom left corner as the origin. Write an equation for the circular hole.Someone plz help me >_<​

Answers

Answer:

  • (x - 48)² + (y - 24)² = 64

Step-by-step explanation:

From the graph we see that

  • The diameter of the circle is: d = 16 mm
  • Then its radius is: r = 16 mm/ 2 = 8 mm
  • The center has x-coordinate: h = 40 + 8 = 48
  • Y-coordinate: k = 32 - 8 = 24

Use circle formula:

  • (x - h)² + (y - k)² = r²

Substitute values to get required equation:

  • (x - 48)² + (y - 24)² = 8²
  • (x - 48)² + (y - 24)² = 64

Answer: (x - 2) ^2 + (y - 6) ^2 = 25
