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
Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.
Answer:
a=11°
b=12°
Step-by-step explanation:
106°+ 7a-3°= 180°
7a= 180°-106°+3°
7a = 77°
a=77/7
a=11°
106° = 9b-2°
108°=9b
108/9 =b
b=12°
Uhhhh x=-2? IM SO SORRY IF THIS IS WRONG PLS ANYONE IF YK THE RIGHT ANSWER COMMENT IM JUS TTRYING TO HELP
