Answer:
y = -1/4x^2 -3/2x +3/4
Step-by-step explanation:
You know that vertex form is ...
y = (1/(4p))(x -h)^2 +k
for a focus-vertex distance of p and a vertex of (h, k).
Here, the focus-vertex distance is 2-3 = -1 (difference of y-coordinates), and the vertex is (h, k) = (-3, 3). This means the vertex form equation is ...
y = -1/4(x +3)^2 +3
Expanding the square gives ...
y = -1/4(x^2 +6x +9) +3
y = -1/4x^2 -3/2x +3/4

<em>Additional comment</em>
The square of a binomial is ...
(x +a)^2 = x^2 +2ax +a^2
PART A :
A,B,C,D
Because if the spinner was spinning on time it would have either landed on any of the given parts a,b,c,d once
PART B:
A and B
They are equally likely to occur because both of them have a portion of 90 degrees.
Hopefully my answer helped :)
Answer:
Step-by-step explanation:
You can do this in a conventional mathematics way by showing each digit as an increasing power of 8, starting with zero
E.g 325 octal
(3 * 8 2 ) + (2 * 8 1 ) + (5 * 8 0 ) = (3 * 64) + (2 * 8) + (5 * 1)
i.e 192 + 16 + 5 = 197 decimal
Note: any number raise to power of 0 in indices is equal to 1
