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)

Tom made a square measuring 8 feet by 8 feet, and had 18 friends stand inside it as if they are watching a band at a small club.
UNO [17]

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

  =(8\ \text{feet})^{2}\\\\=64\ \text{feet}^{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:

n:A=18:64

        =\frac{18}{64}\\\\=\frac{9}{32}\\\\=9:32

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