The objective of this assignment is to design a vertical column such that it will support a given load without buckling. The col

umn has a thin-walled tube cross section as is illustrated in the ϐigure. The column design must be optimized to minimize cost. The design parameters are the inner diameter, d, and the wall thickness, t. Also, this setup of combining an optimization code with solving a physics problem will be an illustrative example of the ϐinal design project code.

A circular merry-go-round has a radius of 5 feet. Find the distance of a spin of one full rotation. Use 3.14 for pi and round th
Sedbober [7]

Option C

The distance of a spin of one full rotation is 31.4 feet

<em><u>Solution:</u></em>

Given that,

A circular merry-go-round has a radius of 5 feet

Radius = 5 feet

We have to find the distance of spin for one full rotation

Distance covered in 1 full of rotation is equal to circumference of circle

<em><u>The circumference of circle is given as:</u></em>

C = 2 \pi r

Where "r" is the radius

C = 2 \times 3.14 \times 5\\\\C = 6.28 \times 5\\\\C = 31.4

Thus the distance of a spin of one full rotation is 31.4 feet

Find (f ° g)(0). *
atroni [7]

Answer:

B

Step-by-step explanation:

Remark

I have to represent f(x) as plus +f(x)

I like to show this situation as +f(g(x)) which I think is much clearer.

+f(x) = 5x - 4    

Solution

+f(g(x)) = 5(g(x)) - 4  What has happened is that wherever you see an x on the right you put in g(x).

Now on the right, you put whatever g(x) is equal  to.

+f(g(x)) = 5(x^2 - 1)  - 4    

Remove the brackets.

+f(g(x)) = 5x^2 - 5 - 4

And make x = 0

+f(g(0)) = 5*0 - 5 - 4

+f(g(0)) = - 9

A student is using the completing the square method to transform the equation x2-10x+ 36 = 0 to the form (x-h) 2+k = 0. which st
andreev551 [17]
Obviously the Correct Step would give him the correct answer lol !

But, here he goes !!

( {x}^{2}  - 10x + 36)

= ( {x}^{2}  - 2(x)(5) +  {(5)}^{2} ) + 11

= (x - 5)^{2}  + 11

✓ So, h = 5 ; k = 11 would make him correct

Answer:

f(x)= e^(2x)-4

change f(x) to y, switch _6 and y. solve for _5x_

The final function

f^(-1) (x)= ln(x+_7(8_)/(_(__)

What is the gradient of the graph shown?<br> Give your answer in its simplest form.
Elis [28]

Answer:

Step-by-step explanation:

When it's clear, the easiest way to do the problem is to used the x and y  intercepts.

This question is one of the clear one.

The x intercept is 2,0

The y intercept is 0,1

You want the slope.

m = (y2 - y1)/(x2 - x1)

y2 = 1

y1 = 0

x2 = 0

x1 = 2

m = (1 - 0)/(0 - 2)

m = 1 / -2

m = -1/2

In this case the slope and gradient have the same value --   - 1/2 or - 0.5
