The diagram to represent the possible cases for common tangents between two circles is as shown in the attachment.

<h3>How to Create Common Tangents?</h3>

A tangent line to a circle is defined as a line that touches the circle at exactly one point, never entering the circle's interior.

  • 1. When one circle is in between another and one circle does not touch the other one, then tangent is not possible.

  • 2. When one circle is in between another and one circle touches the other one at a point inside the circle, then only one tangent is possible.

  • 3. When one circle intersects the other one, then two tangents are possible.

  • 4. When one circle touches the other one at a point outside, then three tangents are possible.

  • 5. When one circle neither intersects the other one nor inside the other one, then four tangents are possible.

Thus, the diagram to represent the possible cases for common tangents between two circles are as attached below.

What is the solution the the following system of equations:
valentina_108 [34]

Answer:

The solution is (-2, 5, 3)

Step-by-step explanation:

2x + 3y - 4z = -1

2(-2) + 3(5) - 4(3) = -1

-4 + 15 - 12 = -1

-16 + 15 = -1

-1 = -1

x - 2y + 5z = 3

-2 - 2(5) + 5(3) = 3

-2 - 10 + 15 = 3

- 12 + 15 = 3

3 = 3

-4x + y + z = 16

-4(-2) + 5 + 3 = 16

8 + 5 + 3 = 16

16 = 16

Therefore, (-2, 5, 3) is a solution.

2x + 3y - 4z = -1

2(-3.6) + 3(0.2) - 4(1.4) = -1

-7.2 + 0.6 - 5.6 = -1

-12.8 + 0.6 = -1

-12.2 = -1

x - 2y + 5z = 3

-3.6 - 2(0.2) + 5(1.4) = 3

-3.6 -0.4 + 7 = 3

-4 + 7 = 3

3 = 3

-4x + y + z = 16

-4(-3.6) + 0.2 + 1.4 = 16

14.4 + 0.2 + 1.4 = 16

16 = 16

(-3.6, 0.2, 1.4) is not a solution.

2x + 3y - 4z = -1

2(2) + 3(5) - 4(-3) = -1

4 + 15 + 12 = -1

31 = -1

x - 2y + 5z = 3

2 - 2(5) + 5(-3) = 3

2 - 10 - 15 = 3

2 - 15 = 3

13 = 3

-4x + y + z = 16

-4(2) + 5 + -3 = 16

-8 + 5 - 3 = 16

-11 + 5 = 16

-6 = 16

(2, 5, -3) is not a solution.

2x + 3y - 4z = -1

2(4) + 3(-7) - 4(-3) = -1

8 - 21 + 12 = -1

-21 + 20 = -1

-1 = -1

x - 2y + 5z = 3

4 - 2(-7) + 5(-3) = 3

4 + 14 - 15 = 3

18 - 15 = 3

3 = 3

-4x + y + z = 16

-4(4) - 7 - 3 = 16

-16 - 7 - 3 = 16

-26 = 16

(4, -7, -3) is not a solution.

Area=legnth times width
legnth=30 and 1/2
width=20
area=30 and 1/2 times 20
area=(30+1/2) times 20
distribute
area=20 times 30+20 times 1/2
area=600+10
area=610
area= 610 m^2




perimiter=legnth +width+legnth+width
perimiter=2legnth+2width
width=6 and 1/2
legnth=10
perimiter=2(10)+2(6 and 1/2)
perimiter=20+13
perimiter=33cm


1. area=610 m^2
2. perimiter=33cm
