Answer:
The vertex form is: y = 3(x-2)^2 + 7
. The vertex is (2, 7)
Step-by-step explanation:
Write the function: y = 3x^2 - 12x + 11 in vertex form
The vertex form of a quadratic equation is:
y = m(x - a)^2 + b where (a,b) is the vertex
For y = 3x^2 - 12x + 11
Solve for m
y = 3(x^2 - 4x) + 11
Complete the Square:
y = 3(x^2 - 4x + 4) + 11 - 4
y = 3(x - 2)^2 + 7
The vertex then is (2, 7)

Answer:
The ratio of this number to the rectangle’s area is 9:32.
Step-by-step explanation:
The information provided are:
- Tom made a square measuring 8 feet by 8 feet.
- He had 18 friends stand inside it as if they are watching a band at a small club.
The area of the square is:
<em>A</em> = (side)²

The number of people standing insider the square is:
<em>n</em> = 18
Compute the ration of <em>n</em> to <em>A</em> as follows:


Thus, the ratio of this number to the rectangle’s area is 9:32.
