Consider this equation. cos(θ) = 4sqrt41/41 If θ is an angle in quadrant IV, what is the value of sin(θ)? HINT: It's not C. A. -5sqrt41/41
B. 5/4
C. 5sqrt41/41
D. -5/4

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

x = 3 ± √(5+y)
