Answer:
x = -1
Step-by-step explanation:
With the axis of symmetry, think of it as where you would slice this line in half, and both sides would look identical to each other. Since this is a quadratic function, this would be at where the vertex is.
The vertex is the part of the line where it "turns" around and starts going the other way. So vertex of this line is at (-1, 3).
Therefore, the axis of symmetry is at x = -1. This is since the function is pointing either up/down, and any value that is x = _ is a vertical line.
Answer:
b. 128°
Step-by-step explanation:
arc LJ = 2 (26) = 52°
arc KL = 180° (half circle)
so
arc JK = 360° - (arc LJ + arc KL)
arc JK = 360° - 232°
arc JK = 128°
Answer
b. 128°

Answer:
a (3,-1)
Step-by-step explanation:
The number that "completes the square" is the square of half the x-coefficient, (-6/2)^2 = 9. Rearranging the given function to include the square trinomial, we have ...
f(x) = x^2 -6x +9 -1 . . . . . . . here, we have 8 = 9 - 1
f(x) = (x -3)^2 -1 . . . . . . . . . . vertex form
Comparing this to the generic vertex form ...
f(x) = (x -h)^2 +k . . . . . . . vertex at (h, k)
we see that h=3 and k=-1.
The vertex is (h, k) = (3, -1).
Hello!
To find the side length of a square with the diagonal you use the equation

a is side length
d is diagonal length
Put in the values you know

Divide

Multiply
a = 22.6
All the sides are 22.6 feet
Add all the sides
22.6 + 22.6 + 22.6 + 22.6 = 90.4
The answer is 90.4
Hope this helps!
