The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius r?

nydimaria [60]

Volume of the cone = (1/3) pi r^2 h

h = 2r so substituting for h:-

V = (1/3) pi r^2 * 2r

V = (2/3) pi r^3

On a coordinate plane, a curved line with a minimum value of (negative 2.5, negative 12) and a maximum value of (0, negative 3)

alekssr [168]

The points on the graph of (-4, 0), (-2.5, -12), and (0, -3), gives;

F(x) > 0 over the interval (-∞, -4)

<h3>Which method can be used to find the true statement?</h3>

From the description of the graph, we have;

Furthest point left of the graph = (-4, 0)

The furthest point right on the graph = (0, -3) = The maximum point

The minimum point = (-2.5, -12)

F(x) < 0 at the minimum point

The minimum point is to the right of x = -4

The point the graph crosses the y-axis = (0, -3)

Therefore;

The interval of the graph where F(x) is larger than 0 is to the left of (-4, 0), is the interval (-∞, -4)

The true statement is therefore;

F(x) > 0 over the interval (-∞, -4)

Casey orders 3 pizzas and 2 orders of breadsticks for a total of $29.50. Rachel orders 2 pizzas and 3 orders of breadsticks for

saveliy_v [14]

The cost of one pizza is $8.5

Step-by-step explanation:

Let,

Cost of one pizza = x

Cost of one bread stick = y

According to given statement;

3x+2y=29.50 Eqn 1

2x+3y=23 Eqn 2

Multiplying Eqn 1 by 2

$2(3x+2y=29.50)\\6x+4y=59\ \ \ Eqn\ 3$

Multiplying Eqn 2 by 3

$3(2x+3y=23)\\6x+9y=69\ \ \ Eqn\ 4$

Subtracting Eqn 3 from Eqn 4

$(6x+9y)-(6x+4y)=69-59\\6x+9y-6x-4y=10\\5y=10$

Dividing both sides by 5

$\frac{5y}{5}=\frac{10}{5}\\y=2$

Putting y=2 in Eqn 1

$3x+2(2)=29.50\\3x+4=29.50\\3x=29.50-4\\3x=25.5$

Dividing both sides by 3

$\frac{3x}{3}=\frac{25.5}{3}\\x=8.5$

The cost of one pizza is $8.5

How many intersections are there of the graphs of the equations below? 1/2x + 5y = 6 3x + 30y = 36 none one two infinitely many

juin [17]

Solve both equations 1/2x + 5y = 6 becomes y = -1/10x + 5/6 and 3x +30y = 36 becomes y = -1/10x + 36/30. Since both equations have the same slope..1/10 the lines are going to be parallel since the constant is different 5/6 vice 36/30. They will never cross.
