Find the diameter, radius, area and circumference of the circle. Show your work.

Answers

Answer 1

Answer:

Step-by-step explanation:

Radius:6ft

Diameter:12ft

Area:

$\pi {r}^(2) = \pi {6}^(2) = \n = 113.097336 = 113.1. {ft}^(2)$

circumference:

$2\pi * r = 2\pi * 6 = \n = 37.6991118 = 37.7 \: ft$

Which formula shows a joint variation?

Answers

The answer is the first option: I, II and III.

The explanation is shown below:

1. By definition, there is a joint variation when a variable depends on two or more different variables. Therefore, you can express it as following:

$y=kxz$

Where $x,y$ and $z$ are the variables and $k$ is the constant of proportionality.

As you can see, $y$ is directly proportional to $x$ and $z$ .

2. Keeping the information above, you have:

I) $V=lwh$ ( $V$ varies jointly with $l$ , $w$ and $h$ .

II) $V=(1)/(3)r^(2)h\pi$ (If $(\pi)/(3)$ is the constant of proportionality, $V$ varies jointly with $r^(2)$ and $h$ ).

III) $V=Bh$ ( $V$ varies jointly with $B$ and $h$ .

Answer : I, II and III

To find volume formula that shows joint variation we analyze each option

Joint variation always depends on atleast two dependent variables

for example y = kxy

The variable y depends on x and y and k is constant of proportionality

V= lwh

It means volume depends on length , width and height. 1 is the constant of proportionality .

$v=(1)/(3) \pi r^2h$

V depends on radius r and height h. Here 1/3 pi is the constant of proportionality

V= BH

V depend on base b and height h . 1 is the constant of proportionality .

if the quanity demanded of soda decreases by 5 percent when the price of soda rises by 100 percent what is the price elasticity of demand for soda

Answers

Price elasticity of demand is calculated as the ratio of change in demand to the ratio of change in price. So if the demand changes -5% when the price changes 100%, the PED = -5% / 100% = -0.05. Most good have a PED < 0, since demand typically decreases when the price is increased.

In the first quadrant you start at (7,4) and move 4 units left and 3 units up.

Answers

Answer:

(3,7)

Step-by-step explanation:

(7,4)

Moving left and right relates to x

Moving up and down relates to y

When you move to the left, you subtract

When you move to the right, you add

When moving up, you add

When moving down you subtract

X= 7-4 = 3

x=3

Y= 4+3 = 7

y = 7

Which expression equals 24?

Answers

Answer:

Lots.

Step-by-step explanation:

12 + 12, 2 x 12, 48 divided 2, etc.

Lots of expressions make 24.

Answer:For this case we must find an expression equivalent to 24, including exponents. To do this, we decompose factor 24. By definition, factorial decomposition consists of writing a number as the multiplication of other numbers.

Then:

We have the "2" is written three times, then:

Answer:24 = 2 to the 3rd power x 3
