5 and 96/100 or if you need to simplify 5 and 24/25
The rule for the linear graph is y=mx
Answer:
d. -7/25
Step-by-step explanation:
π<θ<3π/2 in third quadrant
tanθ = 4/3
sinθ = - 4/5
cosθ = - 3/5
cos 2θ = cos²θ - sin²θ = (- 3/5)² - (- 4/5)² = 9/25 - 16/25 = - 7/25
The range of sinx is [-1; 1]
The range of 3sinx is [-3; 3]
The range of 3sinx + 3 is [0; 6]
Answer: y ∈ [0; 6]
270 is most probably the answer
