Which set of data is correct for the quadratic relation f(x) = 5(x -

Burka [1]

Answer:

Direction parabola opens upward.

Vertex of parabola is (27,-9).

Axis of symmetry is $x=27$ .

Step-by-step explanation:

Note: Option sets are not correct.

The vertex form of a parabola is

$y=a(x-h)^2+k$ ...(1)

where, (h,k) is vertex and x=h is the axis of symmetry.

If a<0, then parabola opens downward and if a>0, then parabola opens upward.

The given function is

$f(x)=5(x-27)^2-9$ ...(2)

On comparing (1) and (2), we get

$a=5>0$ , so direction parabola opens upward.

$h=27,k=-9$ , so vertex of parabola is (27,-9).

So, axis of symmetry is $x=27$ .

A room is 5 meters by meters . How many square 14-inch tiles will it take to floor the room ? I meant to say a room is 5 meters

lesya [120]

Given:

Room is 5 meters by 8 meters.

Measure of squaree tiles is 14-inch.

$\begin{gathered} \text{Area of the room=5}\times8 \\ \text{Area of the room=}40m^2 \end{gathered}$ $1m^2=1550inch^2$ $\begin{gathered} \text{Area of each tile=14}\times14 \\ \text{Area of each tile=}196inch^2 \end{gathered}$ $\begin{gathered} \text{Number of tiles to floor the room=}\frac{40\times1550}{196} \\ \text{Number of tiles to floor the room}=316.3265 \end{gathered}$

Approximately 316 tiles are required to floor the room.
