Write the expression (4x-2)•6(2x+ 7) in the ax2+bx+c What are the values of the coefficient

tresset_1 [31]

The values of the coefficient are ax^2+bx+c=

48x^2-24x+84 and A= 48, B=-24, C=84.

(4x-2)•6(2x+7)=

6•2x+ 6•7

(4x-2)(12x+42)=

4x•12x= 48x^2 4x•42= 168.

-2•12x= -24x -2•42=-84

48x^2-24x+168-84=

48x^2-24x+84=

A= 48, B=-24, C=84

ax^2+bx+c= 48x^2-24x+84.

A cylinder has diameter of 4ft and a height of 9ft. Explain whether halving the diameter has the same effect on the surface area

elena55 [62]

Answer:

See Below

Step-by-step explanation:

The surface area of cylinder is given by the formula:

$SA=2\pi r^2 + 2\pi r h$

Where

r is radius ( diameter is 4, so radius is 4/2 = 2)

h is height ( h = 9)

Lets find original surface are:

$SA=2\pi r^2 + 2\pi r h\\SA=2\pi (2)^2 + 2\pi (2) (9)\\SA=8\pi +36\pi\\SA=44\pi$

<u>Halving diameter:</u>

diameter would be 4/2 = 2, so radius would be 2/2 = 1

So, SA would be:

$SA=2\pi r^2 + 2\pi r h\\SA=2\pi (1)^2 + 2\pi (1) (9)\\SA=2\pi +18\pi\\SA=20\pi$

<u>Halving height:</u>

Height is 9, halving would make it 9/2 = 4.5

Now, calculating new SA:

$SA=2\pi r^2 + 2\pi r h\\SA=2\pi (2)^2 + 2\pi (2) (4.5)\\SA=8\pi + 18\pi\\SA= 26\pi$

Original SA is $44\pi$ ,

Halving diameter makes it $20\pi$

Halving height makes it $26\pi$

So, halving diameter does not have same effect as halving height.

How do you do 51 and 54?

NemiM [27]

51. I checked the comments but I still didn't understand it, sorry :/

54.

(43+45+47+49)=184

They are all odd and they are in consecutive order (one after another)
