What are scientific figures?

1 answer:

8 0

Sig Figs, as they are also known, are important only in Science. But there are three ways you can determine how many sig figs there are. Non-Zero digits are sig figs. Any zeros between two sig figs are significant. (EX: 7008) And, lastly, A final zero(s) in a decimal are significant. (EX: 0.76540800) Last two zeros are significant.

Gnoma [55]

An attempt to divide by zero gives a contradictory result

A rule of algebra broken is dividing by zero (leading to a contradiction) and stating a finite result

Reason:

The given calculation is presented as follows;

1. a > 0, b > 0 given

2. a = b given

3. a·b = b²

4. a·b - a² = b² - a²

5. a·(b - a) = (b + a)·(b - a)

6. a = b + a

7. 0 = b

8. b = 2·b

9. 1 = 2

From line 4, the result are;

4. a·b - a² = b² - a² = 0

5. a·(b - a) = (b + a)·(b - a) = 0

On line 6, both sides where divided by (b - a) = 0, which should given an infinite result

Therefore, one rule of algebra broken is dividing by zero to get a finite result

In line 7, we have;

7. 0 = b

From 6. a = b + a, and a = b, we have;

8. b = 2·b

Therefore, line 9 should be;

9. 0 = 2·0; 0 = 0, given that we have;

1 × 0 = 0

2 × 0 = 0

∴ 1 × 0 = 2 × 0

However

1 ≠ 2

In line 9., by dividing by b = 0, again, we have;

9. 1 = 2 (a contradiction)

Therefore, one rule of algebra that is broken is dividing by zero and having a finite result

What is the pythagorean theorem?

Natalija [7]

Easy,

the Pythagorean theorem is:

$a^{2} + b^{2} = c^{2}$

The a and b, being a value that you HAVE

and

c, being the value you are trying to find.

Example: have 1,2 for a triangle what is the third side?

$1^{2} + 2^{2} = c^{2}$

1+4= $c^{2}$

5= $c^{2}$

Then, just square root to find c.

$\sqrt{5}$ =c

2.2≈c
