Answer:
Step-by-step explanation:
The vertex of this parabola is the midpoint of the focus (-2,4) and where the directrix intersects the axis of symmetry of the parabola (-2,6)
This parabola must open downwards due to the position of the directrix and has equation of the form:
where (h,k) is the vertex.
This implies that:
and
The value of p is the distance from the vertex to the focus:
We substitute all the values into the formula to get:
Or
Answer:
tan A = 20/21
Step-by-step explanation:
tan A = opp side/ adjacent side
tan A = 20/21
The question in the picture is sin A
sinA = opp side/ hypotenuse
sin A = 20 /29
Answer: -3
Step-by-step explanation: 5-8 is -3 so just go 3 to the left from 0 and plug in the point or number
