Answer:
(-3,5) (-3,4)
5-4/-3--3=1/0
It is a vertical line so it's y∈R
Step-by-step explanation:
y = -|x + 4|
The coordinates of vertex of that function is (x; 0).
-|x + 4| = 0
|x + 4| = 0 ⇔ x + 4 = 0 |-4
x = -4
Answer: (-4; 0)
Answer:
Vertex: (-2, 0)
Focus: (-2, 1/4)
Directrix: y = -1/(4a)
Step-by-step explanation:
Given that a parabola has a general form of:
The vertex is at:
The focus falls on the symmetry axis (x=h) of the parabola at:
The directrix is a straight line described by:
If we are given the parabola:
Then:
The vertex of the parabola is (-2, 0)
The focus of the parabola is (-2, 1/4)
The directrix of the parabola is given by the equation y = -1/(4a)
Answer:
Step-by-step explanation:
Rule: never completely trust a diagram that comes with a geometry question. This is a case in point. The "tiny" square is actually much larger than the "larger" square.
If you are trying to find the length of the sides of the squares, the formula is
Area = side^2
3025 = side^2
Take the square root of both sides.
sqrt(3025) = sqrt(side^2)
To find the square root of 3025, do the following
Press √
type in 3025
type in =
You should get 55.
======================
The second square is done the same way
√
90.75
=
And you should get 9.526
