How to solve transformation problems in math

Mathematics
1 answer:
Molodets [167]3 years ago

In this section we are going to see how knowledge of some fairly simple graphs can help us graph some more complicated graphs. Collectively the methods we’re going to be looking at in this section are called transformations.

Vertical Shifts
The first transformation we’ll look at is a vertical shift.

For each equation, determine whether it represents a direct variation, an inverse variation, or neither.
Murljashka [212]

Direct variation is written in the form y = k * x or x = y * k. And, inverse variation is written in the form y = k/x or x = y/k.

For the first problem, if we isolated the y, we would get:

4y = 3x - 1

y = (3/4)x - 1/4

This is written as y = mx + b, which isn’t the form of direct or inverse variation, so the answer is NEITHER.

For the second equation, we could divide by 2 on both sides to isolate x and see if it is in the correct form:

x = 4/y

This is inverse form, so the second question is INVERSE with a constant of variation as 4.

Only the triangles in figures <u>5 are congruent</u>

<h3>Further explanation </h3>

Triangles are said to be congruent if:

  • 1. all three sides equal (SSS ---> side, side, side)
  • 2. two sides and the included angle of 2 triangles, are equal (SAS -> Side, Angle, Side)
  • 3. If the two angles and the included sides of the 2 triangles are equal (ASA -> Angle, Side, Angle)
  • 4. If the two angles and the non-included sides of 2 triangles are equal (AAS -> Angle, Angle, Side)

1. △ABC ≠ △DCE : not congruent

at least 3 parts (sides or angles) are compared, in the picture only 2 sides are compared

2. △ABC ≠ △XYZ : not congruent

the angles not includes between two sides

3. △RST ≠ △VUT : not congruent

a minimum of 3 parts (sides or angles) are compared, in the picture only 1 angle and 1 side are compared

4. △DEF ≠ △DHG :  not congruent

at least 3 parts (sides or angles) are compared, in the picture only 2 sides are compared

5. △JKL ≅ △KJM : congruent with ASA theorem

Determine if the sequence below is arithmetic or geometric and determine the
asambeis [7]

Answer:

Step-by-step explanation:

This is an arithmetic series.

3 , 5 , 7 ,......

Common difference = second term - first term

                                 = 5 - 3

                                  = 2

Simplify sin(tan^(-1)x)
AnnZ [28]
Sin (tan^(-1)X)
Sin (1/tan X)
Sin (1/1 / tan X/1)
Tan X = sin X/cos X

Sin (1/1 / sin X/cos X)
Sin (1/1 • cos X/Sin X)
Sin (cos X/sin X )
Cos X.

I believe the correct answer is cos X.
