Answer:
30 in
Step-by-step explanation:
The parabola will show the vertex in the format: y-k = (x-h)^2, where the vertex point
lies at (h, k).

let's first put it in "y =" standard format:

Since we cannot get a perfect square out of this, we complete the square: a=1, b=2, c=3
(b/2)^2 = (2/2)^2 = 1, so

So there's +2 leftover, since 3-1=2; so:

Now we'll subtract the 2 from both sides to show our vertex:

where our vertex (h, k) is at (-1, 2)
Answer:
C
Step-by-step explanation:
The answer to this problem is 3 11/12.
1.8 3/4= 8 9/12
2.4 5/6 = 4 10/12
if you minus the two numbers, you get 3 11/12.
Any angle that measures less than 90 degree is known as "Acute angle"
In short, Your Answer would be: "Acute Angle"

Answer:
HIG=28°
Step-by-step explanation:
HI is a diameter therefore it's measure is 180°
HI-IG=HG
180-128=HG
52°=HG
HIG=1/2HG
HIG=1/2(56°)
HIG=28°
