Find the slope between points (-4, 8) and (-9, 0). -8/5 4/9 8/5 undefined

daser333 [38]

Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (0 - 8)/(-9 - (-4))
m = (0 - 8)/(-9 + 4)
m = (-8)/(-5)
m = 8/5

Answer: Choice C) 8/5

Complete the function table. Function: k=j-2

Vinvika [58]

Answer:

Step-by-step explanation:

Here the given function is k = j - 2.

Figuring out the value of j when k = 3, we get 3 = j - 2, or j = 5.

When k = 8, 8 = j - 2 yields j = 10.

Likewise, when k = 13, 13 = j - 2 yields j = 15.

Finally, j = 20 when k = 18.

Completing the table, we get:

j k = j - 2

A right triangle is shown. The hypotenuse has length b. The angle opposite to side a is y and the angle opposite to side c is x.

Firlakuza [10]

Answer:

Therefore,

The correct options are

$\sin x = \dfrac{c}{b}\\\\x=sin^{-1}(\dfrac{c}{b})$

$\tan x = \dfrac{c}{a}\\\\x=tan^{-1}(\dfrac{c}{a})$

$\cos y = \dfrac{c}{b}\\\\x=cos^{-1}(\dfrac{c}{b})$

Step-by-step explanation:

Consider a right angle Triangle ΔABC, such that

AB = c = Adjacent side opposite to angle x

BC = a = Adjacent side opposite to angle y

AC = b = Hypotenuse

To Check :

For correct option?

Solution:

In Right Angle Triangle ABC,

$\sin x = \dfrac{\textrm{side opposite to angle x}}{Hypotenuse}\\$

$\cos x = \dfrac{\textrm{Adjacent side to angle x}}{Hypotenuse}\\$

$\tan x = \dfrac{\textrm{side opposite to angle x}}{\textrm{side adjacent to angle x}}$

Substituting the values we get

$\sin x = \dfrac{c}{b}\\\\x=sin^{-1}(\dfrac{c}{b})$

$\cos x = \dfrac{a}{b}\\\\x=cos^{-1}(\dfrac{a}{b})$

$\tan x = \dfrac{c}{a}\\\\x=tan^{-1}(\dfrac{c}{a})$

Now for y

$\sin y = \dfrac{a}{b}\\\\x=sin^{-1}(\dfrac{a}{b})$

$\cos y = \dfrac{c}{b}\\\\x=cos^{-1}(\dfrac{c}{b})$

Therefore,

The correct options are

$\sin x = \dfrac{c}{b}\\\\x=sin^{-1}(\dfrac{c}{b})$

$\tan x = \dfrac{c}{a}\\\\x=tan^{-1}(\dfrac{c}{a})$

$\cos y = \dfrac{c}{b}\\\\x=cos^{-1}(\dfrac{c}{b})$
