(x-4)^2 = 16

(x-4)*(x-4) = 16

FOIL

x*x = x^2

-4 x -4 = 16

-4x + -4x = -8x

x^2-8x+16= 16

SUBTRACT BOTH SIDES

x^2-8x+16= 16
-16 -16

x^2-8x = 0

(x-4)^2 = x^2-16x+12

Correct answer is D

A can in the shape of a cylinder has a diameter of 10 cm and a height of 6 cm. how much wrapping paper is needed to cover the cy

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

To determine the amount of wrapping paper needed to cover the can, we would determine the total surface area of the cylindrical can. The formula for determining the total surface area of a cylinder is expressed as

Total surface area = 2πr² + 2πrh

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

Diameter = 10 cm

Radius = diameter/2 = 10/2

Radius = 5 cm

Height = 6 cm

Therefore,

Total surface area = (2 × 3.14 × 5²) + (2 × 3.14 × 5 × 6)

= 157 + 188.4 = 345.4 cm²

345 cm² of wrapping paper is needed to cover the cylinder.

2) Volume of cylinder = πr²h

Volume of cone = 1/3πr²h

3 × Volume of cone = πr²h

The volume of the cylinder is 3 times greater than the volume of the cone. Therefore, the volume of the cone is 1/3 times lesser than the volume if the cylinder.

I do not how to do this plz help

timurjin [86]

Answer:

Hi!

Step-by-step explanation:

The first thing you want to do is open up a graphing calc of your choice. For the sake of this problem, I'll be using the Desmos calc. You're gonna type in your equations into the calculator (look through attachments). You should then get two lines.

Ask yourself: Are these parallel, perpendicular, or neither.

In this case, they are parallel.

Hope this helps <3
