The (period,amplitude,frequence) of y=1/4cos1/2x is 4pie.<br> one of these is the answer need help
Sidana [21]

Answer:

  period

Step-by-step explanation:

The attached graph shows a period of the function. Its amplitude is 1/4 (vertical distance from centerline to peak). Its period is 4π (horizontal distance from peak to peak). Its frequency is the reciprocal of the period, so would be 1/(4π).

The value 4π is the period of the function.

What... what even is this? I’m so confused! Someone please help, I’ll mark you Brainliest!

These equations calculate kinetic energy and gravitation potential energy.

Kinetic energy (KE) is the energy an object has because of its motion. That’s why it’s calculated using its mass and speed.

Gravitational potential energy (CPE) is the energy an object has due to its position in the gravitational field. This is the energy that can be converted by dropping it or letting it fall which is why the gravitational constant and height as well as mass are needed.

If you have any equations needed to be calculated, I’d be happy to help.

Identify the volume of a sphere if it has a surface area of 465 square units
NeX [460]

Step-by-step explanation:

S.A = 465

4πr²= 465

r². = 36.9

r. = 6.08

volume of a sphere = 4/3πr³

= 4/3π * 6.08³

= 941.8 cm³

Can someone please help me on this question and show the work if you can?
Studentka2010 [4]

Answer:

it is a 60 30 90 triangle so basically 2y is = x

21² + y² = x²

441 + y² = x²

y = x/2 (2y = x)

441 + x²/4 = x²

4x² = 1764 + x²

3x² = 1764

x = exact is 24.248711306 simplied square root would just be 14√3

2y = 14√3

y = 7√3

exact wouldd be 12.124355653

Hey! In the first box, color 4 squares blue. I am not really sure exactly how many to color blue in the second one, but I would go with coloring 2 blue. In the third box, do not mark any squares blue. Hope this helps!
