Answer:
the standard form equation is 1/2x^2-x-3/2=0
the vertex form equation is 1/2(x-1)^2-2=0
Step-by-step explanation:
Unfortunately, this can't be written in slope intercept form but I can write it in standard form(ax^2+bx+c) or vertex form (a(x-h)+k)
The vertex is (1,-2)
I estimate a=1/2 because the graph was widened and that can only be done by a fraction.
So, 1/2(x-1)^2-2=0
To find it in standard form
foil (x-1)(x-1)= x^2-2x+1
Then multiply by 1/2(x^2-2x+1)= 1/2x^2-x+1/2-2
To add 1/2-2. You mulitply -2 by 2/2 which equals 1/2-4/2 which equals -3/2
So the standard form equation is 1/2x^2-x-3/2=0
The answer is going to be divide. hope that helped
For 3a, we see that it states that the submarine is 800 feet below sea level. Since it is below sea level, it is negative (as sea level is 0) and therefore -800, making ii correct.
For 3b, since the elevation is -150 feet, and negative means below sea level, the reef is 150 feet below sea level, making i correct.

Because the hole circle is 100 ,~, and the shaded area is 1/4 of the circle it’s 25,~,
