The number of lines and triangles illustrates combination

The given parameters are:

Total points, n = 9

Total points on each line, r = 2

The number of lines that can be drawn is then calculated  using the following combination formula

Lines = nCr

This gives

Lines = 9C2

Evaluate the combination expression

Lines = 36

Hence, 36 lines can be drawn to join the nine points

The given parameters are:

Total points, n = 9

Total points on each triangle, r = 3

The number of triangles that can be drawn is then calculated  using the following combination formula

Triangles = nCr

This gives

Triangles = 9C3

Evaluate the combination expression

Triangles = 84

Hence, 84 triangles can be drawn using the nine points

a)   c ║ d    CACP

b)   a ║ b    AICP

c)   c ║ d    CACP

d)   a ║ b    SSIASP

Step-by-step explanation:

CACP - Corresponding Angles Congruent postulate

When two parallel lines are cut by a transversal, the pairs of corresponding angles (in the same relative position on different intersections) are congruent.

AICP - Alternate Angles Congruent postulate

When two parallel lines are cut by a transversal, the resulting alternate interior angles (opposite sides of the transversal line) are congruent .

SSIAS - Same Side Interior Angles Supplementary theorem

When two parallel lines are cut by a transversal, the resulting pairs of consecutive interior angles formed are supplementary (sum to 180°).

a)   c ║ d    CACP

The tranversal is line b

b)   a ║ b    AICP

The tranversal is line d

c)   c ║ d    CACP

The tranversal is line a

d)   a ║ b    SSIASP

The tranversal is line c

Answer:

All of them

Step-by-step explanation:

To find the volume of a rectangular prism the formula is V=whl . So to find the dimensions of the box we would have to take the options that they give us and see which ones equal 80 cubic cm.

2⋅5⋅8=80, so right away we know the answer because 5⋅2=10 and 10⋅8=80

4⋅5⋅4=80, that is another possible answer because 5⋅4=20 and 20⋅4=80

10⋅4⋅2=80, yet another answer that is equivalent to 80 because 10⋅4=40 and 40⋅2= 80

So now we know that all three answers are correct and they would all work as possible dimensions  for Max’s box.

Hope this helps!!

Answer:

h = -9

Step-by-step explanation:

Try to make the left hand side and the right hand side equal. By dividing like

h = (-27x+72)/(3x-8)

= [-9(3x-8)]/(3x-8)

= -9

When both sides are equal, you can't find the value of x as there are infinitely many solutions of x.

Looks like the claim is

(2 tan(x) - sin(2x)) / (2 sin²(x)) = tan(x)

Recall the double angle identity for sine:

sin(2x) = 2 sin(x) cos(x)

as well as the definition of tangent:

tan(x) = sin(x) / cos(x)

Then on the left side, we can cancel factors of 2 sin(x) to get

(2 sin(x) / cos(x) - 2 sin(x) cos(x)) / (2 sin²(x))

= (1/cos(x) - cos(x)) / sin(x)

Multiply this by cos(x)/cos(x) :

(1/cos(x) - cos(x)) / sin(x) = (1 - cos²(x)) / (sin(x) cos(x))

Recall that for all x,

sin²(x) + cos²(x) = 1

so that

(1 - cos²(x)) / (sin(x) cos(x)) = sin²(x) / (sin(x) cos(x))

= sin(x) / cos(x)

= tan(x)

as required.

Answer: x=2

Step-by-step explanation:

9(x+7)+5=86

Step 1: Simplify both sides of the equation.

9(x+7)+5=86

(9)(x)+(9)(7)+5     (Distribute)

9x+63+5=86

(9x)+(63+5)=86      (Combine Like Terms)

9x+68=86

Step 2: Subtract 68 from both sides.

9x+68−68=86−68

9x=18

Step 3: Divide both sides by 9.

[tex]\frac{9x}{9} =\frac{18}{9}[/tex]

The best unit of measurement for Alex to use for the ropes he is going to use at camp would be centimeters because it is a measurement that fits the needs of his knot shop.

A unit of measure is a unit that is used as a reference and international standard on length, weight, height, among others.

In the case of length, there are several units of measurement such as:

For a knot-making workshop in a camp, the ideal would be to have a rope of at least 2 or 3 meters. However, the ideal unit of measurement for teaching about knots is centimeters because knots do not require a large amount of rope to tie.

Answer:

5x^2 + 13x

Step-by-step explanation:

Answer:

152°

Step-by-step explanation:

Supplementary angles are two angles that sum to 180°

Complementary angles are two angles that sum to 90°

Let x° = the angle

⇒ Supplement of the angle = 180° - x°

⇒ Complement of the angle = 90° - x°

The difference between the supplement of an angle and twice its complement is 28°:

⇒ (180 - x)°  - 2(90 - x)° = 28°

⇒ 180 °- x° - 180° + 2x° = 28°

⇒ x = 28°

Therefore, the measure of the supplement of 28° is:

180° - 28° = 152°

Answer:

  (a)  (x -6, y -2)

Step-by-step explanation:

You seem to want to see the inverse of the translation T, applied twice. Your notation seems to mean ...

  For T = (x, y) +(a, b)

  T⁻¹ = (x, y) -(a, b)   ⇒   T⁻² = (x, y) -2(a, b)

__

Your given transformation is ...

  T = (x, y) +(3, 1)

which means ...

  T⁻² = (x, y) -2(a, b) = (x, y) -2(3, 1)

  T ⁻² = (x -6, y -2)
