Which quadratic function is represented by the graph?

Vesnalui [34]

The equation of the quadratic function will be y = 5(x – 7)(x – 5). Then the correct option is B.

<h3>What is a quadratic equation?</h3>

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have

The quadratic function is represented by the graph.

Then the equation of the quadratic function will be

The graph is passing through (7, 0) and (5, 0). Then the equation of the function will be

y = a(x – 7)(x – 5)

Then the vertex of the graph is at (6, -5). Then we have

-5 = a(6 – 7)(6 – 5)

-5 = -a

a = 5

Then the equation will be

y = 5(x – 7)(x – 5)

Then the correct option is B.

Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and area of the rug? (

Alenkinab [10]

Answer:

$Width = 20\ in$

$Area = 400\ in^2$

Step-by-step explanation:

Given

See attachment for kite dimension

Required

Determine the width and the area

From the attachment, the height of the kite is:

$Height = 31\ in + 9\ in$

$Height = 40\ in$

The width which is half the height is:

$Width = \frac{1}{2} * Height$

$Width = \frac{1}{2} * 40\ in$

$Width = 20\ in$

The area is:

$Area = \frac{Height * Width}{2}$

$Area = \frac{40\ in * 20\ in}{2}$

$Area = 40\ in * 10\ in$

$Area = 400\ in^2$
