Prove or disprove that (1)/(1-cot x) is the same as (sin x)/(sin x - cos x)

SIZIF [17.4K]

$\dfrac{1}{1-\cot x}=\dfrac{\sin x}{\sin x-\cos x}\\\\L_s=\dfrac{1}{1-\dfrac{\cos x}{\sin x}}=\dfrac{1}{\dfrac{\sin x}{\sin x}-\dfrac{\cos x}{\sin x}}=\dfrac{1}{\dfrac{\sin x-\cos x}{\sin x}}=\dfrac{\sin x}{\sin x-\cos x}=R_s$

$\text{Used:}\\\\\cot x=\dfrac{\cos x}{\sin x}$

Simplify the square root (Picture provided)

Elodia [21]

For this case we must find the value of the following expression:

$\sqrt {8 ^ {17}}$

We have to:

$8 ^ {17} = 8 ^ 1 * 8 ^ {16}$

Substituting:

$\sqrt {8 * 8 ^ {16}}$

By definition of properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So:

$8 ^ {\frac {16} {2}} * \sqrt {8}\\8 ^ 8 * \sqrt {8}$

So we have to:

$\sqrt {8 ^ {17}} = 8 ^ 8 * \sqrt {8}$

Answer:

$8 ^ 8 * \sqrt {8}$

Option A

Line e has a slope of -2/9. line f is perpendicular to e. what is the slope of f

choli [55]

Answer:

9/2

Step-by-step explanation:

In order to find the slope of a line that is perpendicular to another line, you must find the opposite and reciprocal of that slope. So, you have 2/9, and then 9/2.
