What is the vertex of the quadratic function f(x) = (x - 3)(x - 2)?
Grace [21]

Answer:

(\frac{5}{2} , -\frac{1}{4} )

Step-by-step explanation:

<h2><u>Lesson : Finding vertex from quadratic functions ,</u></h2><h2><u /></h2>

Given:

f(x) = (x - 3)(x - 2)

"Vertex"

Find the x intercepts by using the zero product property,

(x - 3)     (x - 2)  =  0

x = 3       x = 2

X-int = (3,0) , (2,0)

Now find the y intercepts by factoring the equation ,

(x - 3)(x - 2)

x * x

x^2

x * -2

x^2 -2x

-3 * x

x^2 -2x -3x

-3 * -2

x^2 -2x -3x + 6

Combining like terms:

x^2 -5x + 6

Replace x with zero,

0^2 -5(0) + 6

6

y intercept = (0,6)

Now graph :

Graph shown

Find vertex -  (\frac{5}{2} , -\frac{1}{4} )

An arc has a length of 123.53 millimeters and a radius of 28 millimeters. What is the measure of the angle of the sector in degr
nadezda [96]

Answer:

Step-by-step explanation:

The formula for arc length in terms of degrees is

A.L.=\frac{\theta}{360}*2\pi r and we have everything we need to fill in to find the angle measure.

123.53=\frac{\theta}{360}*56\pi which is the same as

123.53=\frac{56\pi \theta}{360} and

360(123.53)=56\pi \theta and

\frac{360(123.53)}{56\pi}=\theta so

θ = 253°
