The statement “If the movement of a mass on a spring may be modeled with simple harmonic motion, then its frequency decreases with time” is false.

 

<span>In mechanics and physics, simple </span><span>harmonic motion </span>is a type of periodic motion<span> or oscillation </span><span>motion </span>where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement .

a cylinder shaped can needs to be constructed to hold 400 cubic centimeters of soup. the material for the sides of the can costs
fredd [130]

The dimensions of the can are radius of can = 4cm and

height of can = 78.6cm

What is the volume of cylinder?

A cylinder can be seen as a collection of multiple congruent disks, stacked one above the other. In order to calculate the space occupied by a cylinder, we calculate the space occupied by each disk and then add them up.

Thus, the volume of the cylinder can be given by the product of the area of base and height.

Volume of cylinder = πr²h

According to the given question:

We have V cylinder = V = 400cc

We will first find the areas involved

Let x = radius of base then area of the base =  π*x² and this is the area of the top too

For lateral area we need to get h the height of the cylinder as function of x

V = πx²h   ⇒  h= v/πx²    ⇒   h = 400/πx²

Now the total area of the cylinder is:

A(x) = Area of the base + area of the top + lateral area

A(x) = 2*π*x² + 2πx h ⇒  A(x) =  2*π*x² + 2πx (V/πx² )

A(x) =  2*π*x² + 800/x

Taking derivatives:

A´(x)  =  4πx  - 800/x²

A´(x) = 0                4πx  - 800/x² =0     ⇒ πx - 200/x² = 0

( πx³  -  200 )/ x²  = 0      

πx³  -  200 = 0      

x = 4 cm

and h = 400/πx²    ⇒  h = 78.6 cm

Farmers Bob ,Joe and Larry sold apples at the farmers market .Bob sold 86 apples .Joe sold 12 times as many as Bob .Larry sold h
kotykmax [81]

Answer:

Altogether they sell <u>1634</u> apples.

Step-by-step explanation:

GIven:

Bob, Joe and Larry sold apples at the farmers market.

<u><em>Bob sold 86 apples. </em></u>

<u><em>Joe sold 12 times as many as Bob. </em></u>

<u><em>Larry sold half as many apples as Joe. </em></u>

Now, to find the total apples Bob, Joe and Larry they all sell together.

<u>Number of apples Bob sold</u> = 86.

<u>Number of apples Joe sold</u> = 12 times of 86.

=12\times 86\\\\=1032.

<u>Number of apples Larry sold</u> = \frac{1}{2}\ of\ 1032

=\frac{1}{2} \times 1032

=516.

Now, to get the apples they sell altogether we add the number of apples sold by Bob, by Joe and by Larry:

86+1032+516

=1634.

Therefore, altogether they sell 1634 apples.
