Answer:
n=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11−8n=1−3n
11+−8n=1+−3n
−8n+11=−3n+1
Step 2: Add 3n to both sides.
−8n+11+3n=−3n+1+3n
−5n+11=1
Step 3: Subtract 11 from both sides.
−5n+11−11=1−11
−5n=−10
Step 4: Divide both sides by -5.
−5n
−5
=
−10

Answer:

Step-by-step explanation:
Here, we assume that point A is (-1, 0) and point B is (z, 2). Since angle BAD is 60°, we have ...
2/(z+1) = tan(60°) = √3
z = (2/√3) -1
Putting the value of z into the equation for the parabola lets us find "a".
2 = a(z +1)(z -5) = a(2/√3)(2/√3 -6)
Then ...
a = 2/(4/3 -12/√3) = (6√3)/(4√3 -36)
a = -(3+9√3)/52 ≈ −0.357470332079
