         Cos 30° and sin 60° have the same points on the unit circle.
         cos 30° = 1/2. sin 60° = 1/2
         30° and 60° are complement angles ( 30° + 60° = 90° ).
         sin α = cos ( 90° - α )
         Answer: sin 30° = cos 60°

**WILL GIVE THE BRAINLIEST! & LIKE**
Tamiku [17]
1) combine like terms (k)
0 = 7k
k = 0/7 = 0
zero divided by any numbers will be zero

2) combine the like terms (the constant of -4 + 1)
9 = 6x - 3
add 3 to both sides
12 = 6x
x=2

3) -3+3=0
-4=v

4) 4+3=7
8=k+7
k=1

5)x-5x = -4x
16= -4x
x = -4

y = -3/5(x-3)

y= (-3/5) x + 9/5

Step-by-step explanation:

Step 1 :

The equation of line in point and slope form is (y- y intercept) = m(x-x intercept)

Where m represents the slope and x1 and y1 are points on the line.

Given (-2,3) and (3,0) are points on the line

m = (y2-y1)/(x2-x1) = (0-3)/(3-(-2)) = -3/5

So the equation of the line in point slope form is

(y-0)= -3/5(x-3) = y = -3/5(x-3) [taking the point as (3,0)]

Step 2 :

The equation of a line in slope and intercept form is  y = m x +c

m denotes the slope and the constant c denotes the y intercept (the value of intercept in the y axis when x = 0)

when x = 0, y = 9/5 [using the equation in step 1]

Hence the equation in slope and intercept form is

y= (-3/5) x + 9/5

If f(x) = 2x+1/x-4 what is the value of f^-1(3)
Olegator [25]

Answer:

f^-1(3) = 1.719 or  f^-1(3) = 0.149

Step-by-step explanation:

for inverse function x and y coordinates are flipping so graph the function and find for what x - coordinate y- coordinate = 3

in case that f(x) = 2x + \frac{1}{x-4} than f^-1(3) = 1.719

in case that f(x) = 2x + \frac{1}{x} -4 than f^-1(3) = 0.149
