Domain are those values of x for which function is defined. f(x) is not defined at x = 3. Therefore Domain is

x∈ (⁻∞, +∞) - {3}

4. A triangle has vertices A(4, 2), B(3, 7), and C(–4, –5).
Alex

To draw the median of the triangle from vertex A, the mid point of BC must be determined. The median of the vertex A is given at (-1/2, 1). See explanation below.

<h3>How you would draw the median of the triangle from vertex A?</h3>

Recall that B = (3, 7)

and            C = (-4, -5).

  • Note that when you are given coordinates in the format above, B or C = (x, y)
  • Hence the mid point of line BC is point D₁ which is derived as:
    D₁ [ (\frac{3-4}{2}) , (\frac{7-5}{2}) ]
  • hence, the Median of the Vertex A = (-1/2, 1).

Connecting D' and A gives us the median of the vertex A. See attached graph.

<h3>What is the length of the median from C to AB?</h3>

Recall that
A → (4, 2); and

B → (3, 7)

Hence, the Midpoint will be

[(\frac{4+3}{2} ), (\frac{2+7}{2} )]

→  (\frac{7}{2}, \frac{9}{2} )

Recall that

C → (-4, 5)

Hence,

\overline{C D_{2} } =  \sqrt{[(-4 -\frac{7}{2} })^{2}  + (-5-\frac{9}{2} )^{2} ]

Simplified, the above becomes


= √(586)/2)

= 24.2074/2

= 12.1037

The length of the Median from C to AB ≈ 12

What is the answer? What is the answer?
ahrayia [7]

Answer:

  B.  m∠RTS = 78°

Step-by-step explanation:

The sides GH and GI of ΔGHI have the same length, so their opposite angles, ∠I and ∠H will have the same measures. Call that measure "x".

The sum of angles in a triangle is 180°, so we have ...

  24° +x +x = 180°

  2x = 156° . . . . subtract 24°

  x = 78° . . . . . . divide by 2

The triangle similarity statement tells you that ∠T will have the same measure as ∠I, which is x, or 78°.

  m∠RTS = 78°
