Answer:

About 23.9 in

Step-by-step explanation:

Given radius (R) = 3.8

Diameter = 2R = 7.6

Circumference = 2πR

= 7.6π

= 23.876104167282

Area = πR2

= 14.44π

= 45.364597917837

Rewrite each equation in vertex form by completing the square. Then identify the vertex.

ioda

ANSWER

Vertex form;

$y = 3( {x + \frac{3}{2} })^{2} - \frac{35}{4}$

Vertex

$V( - \frac{3}{2} , - \frac{35}{4} )$

EXPLANATION

Given:

$f(x) = 3 {x}^{2} + 9x - 2$

We complete the square as follows:

$y = 3( {x}^{2} + 3x) - 2$

$y = 3( {x}^{2} + 3x + \frac{9}{4} ) - 2 - 3 \times \frac{9}{4}$

The vertex form is:

$y = 3( {x + \frac{3}{2} })^{2} - \frac{35}{4}$

The vertex is

$V( - \frac{3}{2} , - \frac{35}{4} )$
