Step-by-step explanation:

The compass would connect the two || lines for an equal amount of time. Though if I am wrong feel free to let me know.

If the compass is placed on the original line point, then is will be the exact same spot and angle for the other line. They should met and form a right angle .

What is wrong with the following proof? Clearly we know that 1 does not equal 2. What rule of algebra did we break that makes th
Gnoma [55]

An attempt to divide by zero gives a contradictory result

A rule of algebra broken is <u>dividing by zero</u> (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 <u>dividing by zero</u> and having a finite result

V = (pi r^2 h/3)...solve for h​
guapka [62]

Answer:

h = (3×V)/ (pi×r²)

Step-by-step explanation:

v =  \frac{\pi {r}^{2} h}{3}

3 \times v = \pi {r}^{2} h

h =  \frac{3v}{\pi {r}^{2} }
