Mr. Hamilton decorates his U.S. History classroom by putting up pictures of the presidents. The wall is 9.75 feet long. In the c

Archy [21]

Answer:

8 pictures

Step-by-step explanation:

Given

$Window = 5\frac{3}{4}ft$

$Wall = 9.75ft$

$Pictures = 6\ inches$

Required

Determine the number of pictures

First, we need to calculate the length of the available space

This is calculated by subtracting the width of the window from the width of the wall.

$Space = Wall - Window$

$Space = 9.75 - 5\frac{3}{4}$

Convert fraction to decimal

$Space = 9.75 - 5.75$

$Space = 4ft$

Since, the pictures are placed side by side.

This means that, there's no empty space between them.

Number of pictures is:

$Number = \frac{Space}{Pictures}$

$Number = \frac{4\ ft}{6\ in}$

Convert feet to inches

$Number = \frac{4 * 12\ in}{6\ in}$

$Number = \frac{48\ in}{6\ in}$

$Number = \frac{48}{6}$

$Number = 8$

<em>Hence, 8 pictures can fit the wall</em>

Determine the equation of quadratic function represented by the table of value below.

Svetllana [295]

Answer:

Step-by-step explanation:

The general rule for the quadratic function is

$y=ax^2+bx+c$

Use the data from the table:

$y(0)=6\Rightarrow 6=a\cdot 0^2+b\cdot 0+c\\ \\y(1)=4\Rightarrow 4=a\cdot 1^2+b\cdot 1+c\\ \\y(-1)=10\Rightarrow 10=a\cdot (-1)^2+b\cdot (-1)+c$

We get the system of three equations:

$\left\{\begin{array}{l}c=6\\ \\a+b+c=4\\ \\a-b+c=10\end{array}\right.$

From the first equation

$c=6,$ then

$\left\{\begin{array}{l}a+b=-2\\ \\a-b=4\end{array}\right.$

Add these two equations:

$a+b+a-b=-2+4\\ \\2a=2\\ \\a=1$

So,

$b=-2-a=-2-1=-3$

The quadratic function is

$y=1\cdot x^2-3x+6\\ \\y=x^2-3x+6$
