Fiona has proved that a function, f(x), is an arithmetic sequence. How did she prove that? A. She showed that an explicit formula could be created. B. She showed that a recursive formula could be created. C. She showed that f(n) ÷ f(n - 1) was a constant ratio. D. She showed that f(n) - f(n - 1) was a constant difference.

Answers

Answer 1
Answer:

Answer:

Option D is correct

Step-by-step explanation:

Option D is correct

Being an arithmetic sequence there will be common difference between the consecutive terms

Option A is incorrect because it is not necessary that explicit formula is an arithmetic sequence we can create explicit formula for any sequence

Option B is incorrect because recursive formula can be created for any sequence for geometric series also.

Option C is incorrect because the sequence that has constant ratio is the geometric sequence not an arithmetic sequence.

Answer 2
Answer:

Answer:

D. She showed that f(n) - f(n - 1) was a constant difference.

Step-by-step explanation:

A sequence is called arithmetic if there is constant difference between consecutive numbers,

Thus, option D is correct.

In Explicit formulas, we define each term in a sequence directly,

Thus, there are many sequences other than arithmetic that have explicit formula,

i.e. Option A can not be true.

Now, recursive formula defines the relation between successive terms,

Thus, there are many sequences other than arithmetic that have recursive formula,

i.e. Option B can not be true.

Also, if the ratio between successive terms is constant then the sequence is a Geometric sequence,

A GP can not be an AP,

i.e. Option D can not be true.

Answer:

a 90° counterclockwise rotation about the origin

a 180° rotation about the origin

a 90° clockwise rotation about the origin

a 90° counterclockwise rotation about

the origin and then a 180° rotation

about the origin

Step-by-step explanation:a 90° counterclockwise rotation about the origin

a 180° rotation about the origin

a 90° clockwise rotation about the origin

a 90° counterclockwise rotation about

the origin and then a 180° rotation

about the origin

Final answer:

A 90° counterclockwise rotation is the same as a 270° clockwise rotation. A 180° rotation is the same as a reflection across both axes. A 90° clockwise rotation is the same as a 270° counter-clockwise rotation. Two separate rotations of 90° counter-clockwise and then 180° are the same as rotations of 90° clockwise and then 180°.

Explanation:

In mathematics, especially in geometry, transformations involve changing the position, size or shape of a figure. The question is about matching specific transformations or sequence of transformations to its equivalent transformation.

  1. A 90° counterclockwise rotation about the origin is equivalent to a 270° clockwise rotation about the origin because they both result in the same final position.
  2. A 180° rotation about the origin is equivalent to a reflection across the x-axis and then a reflection across the y-axis. Both of these transformations result in the figure being flipped over the origin.
  3. A 90° clockwise rotation about the origin  is equivalent to a 270° counterclockwise rotation about the origin as they both result in the same final position.
  4. A 90° counterclockwise rotation about the origin and then a 180° rotation about the origin is equivalent to a 90° clockwise rotation about the origin and then a rotation 180° about the origin because they both result in the same final position.

Answers

the areas of the cubes are
a =  {8}^(3)  = 512 \n  \n b =  {5}^(3)  = 125

so the answer is
512 / 125 = 4.1

-10n + 3(8+8n)=-6(n-4)

Answers

First we have to multiply factor by every argument from the parenthesis.
-10n+3(8+8n)=-6(n-4)
-10n+3*8+3*8n=-6n+6*4
-10n+24+24n=-6n+24
24+14n=-6n+24        /-24
14n=-6n               /+6n
20n=0                 /:20
n=0 - its the answer
