D) 37 degrees, 52 minutes
Step-by-step explanation:
3x-2y+1=0 y = 3/2 x + 1/2 ... slope₁ (m₁ = 3/2)
x-3y=0 3y =1/3 x ... slope₂ (m₂ = 1/3)
acute angle between two slopes: tan θ = (m₁-m₂) / (1+m₁*m₂)
tan θ = (3/2 - 1/3) / (1 + 3/2*1/3) = (7/6) / (3/2) = 7/9 = 0.77777777
θ = 37.875°

Why is the answer D?
Sedaia [141]

Step-by-step explanation:

Inflection points are where a function changes concavity (the second derivative changes signs).  At x = 4, f"(x) goes from negative to positive, so that's an inflection point.  However, at x = 8, we don't know if f"(x) changes signs or not.  So we can't say that that's an inflection point.
