Write the quadratic function f(x) = 3x2 - 6x + 9 in vertex form. A) f(x) = 3(x - 3)2 + 9 B) f(x) = 3(x - 1)2 + 6 C) f(x) = 3(x +

ludmilkaskok [199]

Answer:

Option B $f(x)=3(x-1)^{2}+6$

Step-by-step explanation:

we have

$f(x)=3x^{2} -6x+9$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)-9=3x^{2} -6x$

Factor the leading coefficient

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

Complete the square. Remember to balance the equation by adding the same constants to each side

$f(x)-9+3=3(x^{2} -2x+1)$

$f(x)-6=3(x^{2} -2x+1)$

Rewrite as perfect squares

$f(x)-6=3(x-1)^{2}$

$f(x)=3(x-1)^{2}+6$ ------> equation in vertex form

the vertex is the point $(1,6)$

The area of a rectangle is represented by the polynomial 16x2  56x . The width of the rectangle is given by thebinomial 2x7. (

weqwewe [10]

Answer:

a) Length = $8x$

b) Width = 27 units

Step-by-step explanation:

We are given the following in the question:

Area of rectangle, A =

$A = 16x^2 + 56x$

Width of rectangle, w =

$w = 2x + 7$

a) Length of the rectangle.

Area of rectangle is given by:

$A = l\times w$

where l is the length of rectangle.

Putting values, we get,

$16x^2 + 56x = a(2x+7)\\\\l = \dfrac{16x^2 + 56x}{2x + 7}\\\\l = \dfrac{8x(2x+7)}{2x+7}=8x$

b) Width of rectangle

Length of rectangle = 80

$8x = 80\\\Rightarrow x = 10$

Thus, width of rectangle is

$2x + 7\\=2(10) + 7= 27$

Thus, the width of rectangle is 27 units.

Eliza bought a meal that cost $12.00. She tipped the waiter 25%of that amount . How much was the tip ?

nignag [31]

You want to find 25% of $12. 25% also equals 1/4. 1/4 of 12 (or 12 divided by 4) is $3.

What is 7×11+3×3-16/2

Brums [2.3K]

Hi,

Let's start with the equation:

(7)(11)+(3)(3)−16/2

Next multiply:

=77+(3)(3)−16/2

=77+9-16/2

Add:

=86−16/2

=86−8

=78

Have a great day!

Find Lateral Surface area

fiasKO [112]

Answer:

To find the lateral surface area, we will find half of the perimeter of the base and multiply it by the slant height of the side triangles. Each triangle has a slant height. The slant height is the height of each triangle, not the height of the pyramid.
