What is the area of a regular octagon with 12 as each side. Round to nearest hundredth.

Answers

695.29 is the area of a octagon with a area of 12 as each side.

the population of a bacteria culture doubles in number every 12 minutes. the ratio of the number of bacteria at the end of 1 hour to the number of bacteria at the beginning of the hour is? ...?

Answers

Let's say the number of bacteria you initially have is "a." The number of bacteria doubles every twelve minutes, which means that it doubles 5 times in an hour. You have(2)(2)(2)(2)(2)a=a∗2^5=32a at the end of the hour. You started out with only a. This means your ratio is 32a/a = 32.

Answer:

Step-by-step explanation:

Let X be the number of bacteria at the initial time.

At 12 minutes = 2 X

At 24 minutes = 4X

At 36 minutes = 8X

At 48 minutes = 16X

At 60 minutes = 32X

The ratio between the final and the initial instant will be: 32X / X = 32

What is the surface area of a piece of pipe that is open at both ends, has a radius of 6 inches, and a height of 18 inches? (Use 3.14 for π.)

Answers

it's 2x3.14 times 6 times 18

2π(6)(18)

aka lateral area

you can imagine it like this:
imagine you take a sheet of paper and roll it into a tube
the lateral aera=circumference times height because if yo open the paper, the area is legnth times width, and when you roll it up, width turns into circumference

so

LA=h(circumference0
LA=h2pir
LA=18*2*pi*6
LA=216pi
pi=3.14 for this question
LA=678.24

SA=678.24 in²

what is an acrostic poem for the word triangle?

Answers

T- Triangle sum and Third angles theorems
R- Right Triangle
I- Isosceles Triangle
A- Acute Angles
N- n-fold rotation symmetry for "E" triangles
G- Geometry
L- Legs of a triangle
E- Equilateral and Equiangular Triangles

Final answer:

An acrostic poem for the word 'triangle' is a creative way to convey various attributes of the geometric shape or to create a poem with each line starting with the corresponding letter. The poem can be directly related to the properties of a triangle or more abstract.

Explanation:

An acrostic poem uses the first letter of each line to spell out a word vertically. For the word 'triangle', an acrostic poem might be a creative way to describe the characteristics of a triangle, or it could be abstract, using each letter to begin a line that doesn't necessarily relate to the shape but instead creates a coherent poem.

Here is an example of an acrostic poem for the word 'triangle':

Three sides enclosing space,

Reminder of structure and base,

In geometry, an essential grace,

Angles acute, obtuse, or right,

Nestled within, points of light,

Guiding principles of design,

Lines intersect by plan divine,

Eternally, three lines combine.

Remember, while writing an acrostic for 'triangle', you may also use the opportunity to incorporate into your poem mnemonics for the relationships between the sides and angles of a right triangle, such as 'SOHCAHTOA', or explore the figurative and metaphorical implications of the shape as referenced in literary examples or the sciences.

Which of the following represents the graph of f(x) = 2x + 2? i will give a medal if you help cooperatively

Answers

our function is:
f(x) = 2^x + 2

To find which graph represents this function we should find at least 2 points. We take some value of x we want and calculate y for it. And do that at least 2 times (can be done 1 time but its likely that some graph match in some points)

for x = 0 we get
f(x) = 3

for x = 1
f(x) = 4

we can also note that f(x) cannot be less than 2 because 2^x is always greater than 0, and that as x increments f(x) increments. With all of this in mind answer is last graph.

The sum of the perimeters or two different squares is 32 centimeters , and the difference between there perimeters is 8 centimeters. if x represents the side length of the larger square and y represents the side length of the smaller square , Which of the following systems of equations could be used to find the dimensions of the squares?

A. x+y=32
x-y=8

B. 4x+4y=32
4x-4y=8

C. 2x+2y=32
2y-2x=8

D. 2x+2y=32
4x-2y=8

Answers

Final answer:

The correct system of equations to find the dimensions of the squares is option A: x + y = 32 and x - y = 8.

Explanation:

To find the dimensions of the squares, we can set up a system of equations. Let x represent the side length of the larger square and y represent the side length of the smaller square.

The sum of the perimeters is given as x + y = 32. The difference between the perimeters is given as x - y = 8.

So, the correct system of equations to find the dimensions of the squares is option A: x + y = 32 and x - y = 8.

Final answer:

The correct system of equations to find the dimensions of the squares is x + y = 32 and x - y = 8. Solving this system using the method of elimination gives us the dimensions of the squares: 20 cm for the larger square and 12 cm for the smaller square.

Explanation:

The correct system of equations to find the dimensions of the squares is:

x + y = 32

x - y = 8

To solve this system, we can use the method of elimination. Adding the two equations will eliminate the y terms, allowing us to solve for x.

Adding the equations:

x + y + x - y = 32 + 8

2x = 40

x = 20

Substituting the value of x back into one of the original equations, we can solve for y.

Using the equation x + y = 32:

20 + y = 32

y = 12

Therefore, the dimensions of the larger square are 20 cm, and the dimensions of the smaller square are 12 cm.

Simplify.

If A(x1, y1), B(x2, y2), C(x3, y3), and D(x4, y4) form two line segments, AB and CD , which of these conditions needs to be met to prove that AB is perpendicular to CD?

see attachment for choices

Answers

the answer is the third choice
it is c)
[y4-y3/x4-x3][y2-y1/x2-x1]= -1

proof
two lines are perpendicular if the product of their slope equals -1

Answer:

[tex]\frac{y_4-y_3}{x_4-x_3}\times \frac{y_2-y_1}{x_2-x_1}=-1[/tex]

Step-by-step explanation:

We know that,

If two line segments are perpendicular then the product of their slope is equal to -1,

Also, the slope of a line segment having the end points [tex](x_n,y_n)[/tex] and [tex](x_m,y_m)[/tex] is,

[tex]m=\frac{y_m-y_n}{x_m-x_n}[/tex]

So, the slope of line segment AB having end points [tex]A(x_1,y_1)[/tex] and [tex]B(x_2,y_2)[/tex] is,

[tex]m_1=\frac{y_2-y_1}{x_2-x_1}[/tex]

Similarly, the slope of line segment CD having end points [tex]C(x_3,y_3)[/tex] and [tex](x_4,y_4)[/tex] is,

[tex]m_2=\frac{y_4-y_3}{x_4-x_3}[/tex]

Hence, by the above property of perpendicular line segments ,

If AB and CD are perpendicular then,

[tex]m_1\times m_2=-1[/tex]

[tex]\implies \frac{y_4-y_3}{x_4-x_3}\times \frac{y_2-y_1}{x_2-x_1}=-1[/tex]

Third option is correct.

Which point satisfies the equation 2x+3y=8? A) (-1,3) B) (2,2) C) (-2,4) D) (1,4)

Answers

The answer would be C(-2,4) because if you substitute that into the equation, you will get the answer of 8 2(-2)+3(4) = 8 ..

Therefore C(-2,4) satisfies the equation.

:)

Final answer:

The point that satisfies the equation 2x+3y=8 is (1,4).

Explanation:

To find the point that satisfies the equation 2x + 3y = 8, we can substitute the x and y values from each option into the equation and see which option makes the equation true.

Let's try option A, (-1,3): 2(-1) + 3(3) = -2 + 9 = 7, which is not equal to 8.

Continuing this process for options B, C, and D, we find that the point (1,4) satisfies the equation 2x + 3y = 8.
