The slope is (y2 - y1) / (x2 - X1) and you will use this formula A TON in math!!!
So,
(4 - 2) / (5 - 1) = 2/4 = 1/2

Answer:

$\frac{15}{17}$

Step-by-step explanation:

$\cos( \alpha ) = \frac{ad}{hip} \\ \\ \sin( \alpha ) = \frac{op}{hip}$

Pythagorean theorem

hip² = op² + ad²

17² = x² + 8²

x² = 17² - 8²

$x \: = \sqrt{{17}^{2} - {8}^{2} } \\ x = \sqrt{289 - 64} \\ x = \sqrt{225} \\ x = 15$

$\sin( \alpha ) = - \frac{15}{17}$

$\sin( - \alpha ) = \frac{15}{17}$

What is number 20 simplified?

guapka [62]

Answer:

----------

5w^11

Step-by-step explanation:

8/20 reduces to 2/5, and (w^(-2)) / w^9 becomes 1 / w^11.

Overall, #20 reduces to:

----------

5w^11

Recall the rule of exponents:

w^a

----------- = w^(a-b)

w^b

and note that

w^(-2)

------------ = w^(-2-9) = w^(-11) (same as above)

w^9
