Are a rational expression and its simplified forms equivalent? Provide mathematical examples to support your opinions.

1 answer:

7 0

Yes rational expression and its simplified forms are equivalent.

Rational expression are those that contain fractions.

Example:
25/50 is a rational expression but it is not yet in its simplest form.

25/50 ⇒ 5/10 ⇒ 1/2

1/2 is the simplest form of 25/50.

They are equivalent:

1/2 = 25/50
1*50 = 2*25
50 = 50

or
1/2 = 0.50
25/50 = 0.50

I need help on these three questions I’m so confused on how to answer them

GalinKa [24]

Answer:

1. S(1) = 1; S(n) = S(n-1) +n^2

2. see attached

3. neither

Step-by-step explanation:

1. The first step shows 1 square, so the first part of the recursive definition is ...

S(1) = 1

Each successive step has n^2 squares added to the number in the previous step. So, that part of the recursive definition is ...

S(n) = S(n-1) +n^2

2. See the attachment for a graph.

3. The recursive relation for an arithmetic function is of the form ...

S(n) = S(n-1) +k . . . . . for k = some constant

The recursive relation for a geometric function is of the form ...

S(n) = k·S(n-1) . . . . . . for k = some constant

The above recursive relation is not in either of these forms, so it is neither geometric nor arithmetic.
