Check the picture below.

$\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{16})\qquad (\stackrel{x_2}{10}~,~\stackrel{y_2}{8}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{8}-\stackrel{y1}{16}}}{\underset{run} {\underset{x_2}{10}-\underset{x_1}{0}}}\implies \cfrac{8}{10}\implies \cfrac{4}{5}$

So you need to use the inverse tan to find the measure of angle c.

So since tan is opposite over adjacent.

You get the inverse tan of 6/8. And you get 36.87 degrees.

If p% of q is k, then what is q% of p.

vfiekz [6]

The following equation expresses p% of q is k.
$\frac{p}{q}\times100=k$
Then we can write q% of p as:
$\frac{q}{p}\times100=\frac{1}{k}$
So the answer is 1/k

What does x equal in x^3-9x+1=0

12345 [234]

X^3 -9x+1= 0 (minus 1)

X^3-9x=-1 (divide by 9)

x^3-x=-1/9

But it doesn’t work any further so you have written it wrong

Given the following coordinates complete the reflection transformation.

Minchanka [31]

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , then

A (- 1, - 5 ) → A' (- 1, 5 )

B (2, - 3 ) → B' (2, 3 )

C (3, - 5 ) → C' (3, 5 )

Under a reflection in the y- axis

a point (x, y ) → (- x, y ) , then

A' (- 1, 5 ) → A'' (1, 5 )

B' (2, 3 ) → B'' (- 2, 3 )

C' (3, 5 ) → C'' ( - 3, 5 )
