Answer: C
Step-by-step explanation:
In the quadrant IV, it is only a cos θ that is positive.
Given that tan θ = –8∕15
Where tan θ = opposite ÷ adjacent
Where opposite = 8 and adjacent = 15
We can find the hypothenus by using pythagorean theorem
Hypothenus = sqrt(15^2 + 8^2)
Hypothenus = sqrt(289)
Hypothenus = 17.
Sin θ = opposite ÷ hypothenus
Sin θ = 8/17
Since Sin θ is also negative in the fourth quadrant, therefore
Sin θ = - 8/17
Option C is correct.
2(36-4t) t= 3.4
point (0,2) (4,-1)
slope = (y2-y1)/(x2-x1)
m= ((-1-2))/(4-0)
m=-3/4
Choice B
(0,2) and (4,-1)
Slope
m = (2 + 1)/(0 - 4)
m = -3/4
Answer
B. -3/4
