I think it is D cause it could be equal
Answer:
115/24 =4.7916
Step-by-step explanation:
Based on information provided this is what I think is the answer
Answer/Step-by-step explanation:
Reference angle = θ
Opposite side = 11.9
Adjacent side = 10
Applying the trigonometric ratio, TOA, we have:
Tan θ = opp/adj
Tan θ = 11.9/10
θ = tan^{-1}(11.9/10)
θ = 49.9584509° ≈ 50.0° (to one d.p)
Apply pythagorean theorem to find AB:
Thus:
AB = √(11.9² + 10²)
AB = √241.61
AB ≈ 15.5 (to 1 d.p)
Answer:
f(g(- 2)) = 5
Step-by-step explanation:
Evaluate g(- 2) then use this result to evaluate f(x)
g(- 2) = (- 2)² - 5 = 4 - 5 = - 1, then
f(- 1) = - (- 1) + 4 = 1 + 4 = 5
