Find the coordinates of the turning point of y = x^2 + 8x + 17
Amiraneli [1.4K]

Answer:

(-4 , 1)

Step-by-step explanation:

We know that the turning point of any parabola is in its vertex. The x of the vertex can be calculated with the formula:

x = -b/2a

In our case b = 8, a = 1, so:

x = - 8/2 = -4

We plug this value into our original equation and find the y of the vertex:

(-4)^2 + 8(-4) + 17 = 16 - 32 + 17 = 1

Vertex = (-4 ; 1)

Given:

The height of the triangle = 3 feet

The base of the triangle = 3 feet

To Find:

The area of the hexagonal table = "

Solution:

<u>Step 1: Finding the area of the triangle</u>

The area of the triangle  =\frac{1}{2} \times base \times height

On substituting the values

The area of the triangle is =\frac{1}{2} \times 3 \times 3

The area of the triangle  = \frac{9}{2} square feet

<u>Step 2 : Finding the area of the hexagonal table </u>

The area of the hexagonal table is  =  6  X area of one triangle

The area of the hexagonal table  = 6 \times \frac{9}{2}

The area of the hexagonal table  = \frac{54}{2}

The area of the hexagonal table  = 27 square feet
