Answer:

Explanation:

Volume for a cylinder is V= (pi)(r^2)(h)

r being radius, h being height.

The radius is 2x+1, so square that

(2x+1)^2 = 4x^2 + 4x + 1

Then multiply by 6x, the height

(4x^2 + 4x + 1)(6x) = 24x^3 + 24x^2 + 6x

Then multiply each term pi, which would be answer C.

Suppose you mark n points on a circle, where n is a whole number greater than 1. The number of segments you can draw that connec

leonid [27]

The expression for the number of segments drawn out of the n number of points in the circle is,
n² / 2 - n / 2
Substituting directly to the expression the number of points, n, which is equal to 8,
8² / 2 - 8 / 2 = 28
Thus, there are 28 segments that can be drawn from the points.

The price of one bag of popcorn is $3.75

Step-by-step explanation:

Let,

x represent the cost of a bag of popcorn

y represent the cost of a drink.

According to given statement;

4x+12y=30 Eqn 1

x+6y=11.25 Eqn 2

Multplying Eqn 2 by 2

$2(x+6y=11.25)\\2x+12y=22.50\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 1

$(4x+12y)-(2x+12y)=30-22.50\\4x+12y-2x-12y=7.50\\2x=7.50$

Dividing both sides by 2

$\frac{2x}{2}=\frac{7.50}{2}\\x=3.75$

4x+12y=30 and x+6y=11.25 can be used to find the price of one bag of popcorn and the price of one drink.

The price of one bag of popcorn is $3.75

What is the slope- intercept equation of the line that passes through(0,2) and (6,6)?

Vsevolod [243]

Answer:

y = 2/3x +2

Step-by-step explanation:

First we need to find the slope

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

= (6-2)/(6-0)

=4/6

=2/3

The slope intercept form of the equation for a line is

y= mx+b

y =2/3 x +b

We know the y intercept is 2 (the y intercept is when x=0)

y = 2/3x +2
