SAT question Can someone explain to me what this is asking
1 answer:
Answer:
B
Step-by-step explanation:
The vertex is the turning point of the parabola.
First find the zeros by equating y to zero, that is
(x - 6)(x + 12) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 12 = 0 ⇒ x = - 12
The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros, thus
=
=
= - 3
Thus the x- coordinate of the vertex is x = - 3 → B

Answer:
cot(θ°) = 2000 radians
Step-by-step explanation:
Data provided in the question:
The value of tan(θ°) = −0.0005
To solve:
cot(θ°)
Now,
we know the relation between cot and tan function as:
cot(θ°) =
therefore on substituting the value of theta in the above relation, we can find the value of cot(θ°)
Thus,
cot(θ°) =
or
cot(θ°) = 2000
