To solve this problem you must apply the proccedure shown below:
 1. You have the following parametric equations given in the problem above: 
<span> x=e^3t
 y=e^-t</span> 
 2. Therefore, you must solve fot et in the second equation, as below:
 y=e^-t
 y=1/e^t
 e^t=1/y
 3.Substitute into the first equation:
 x=e^3t
 x=(e^t)^3
 x=(1/y)^3
 x=1/y^3   (y>0)
 The answer is: x=1/y^3  (y>0)

Which expression is equivalent to 4 square root 6 divided by 3 root 2?
saw5 [17]

Answer:

\sqrt[12]{55296}/2

Step-by-step explanation:

\sqrt[4]{6}/\sqrt[3]{2}=1.2422

\sqrt[12]{27}/2=0.66 <-- not matching with the top expression.

\sqrt[4]{24}/2=1.11<--not matching with the top expression.

\sqrt[12]{55296}/2=1.2422<-- matches!!

\sqrt[12]{177147}/3=0.91<-- not matching with the top expression.

Rafael wanted to order half a medium pizza at a restaurant. The waiter told him that a medium pizza could be cut into 6 or 8 sli
Nady [450]

Answer:

The wrong in Rafael reason is that 3/6 = 4/8 = 1/2 pizza

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- When we have a quantity we can divided it to many equivalent

 fractions

- Equivalent fractions means fractions equal each other

- We can find the equivalent fraction by multiply or divide the two

 terms of the fraction by the same number

- Ex: We can divide a circle into two equal parts each part is 1/2 the

 circle, if we multiply each term of the fraction by 2 (up and down)

 then we will have 2/4 which is equivalent to 1/2 the circle

- Then we can divide the circle by 2 parts with many equivalent fractions

 1/2 = 2/4 = 3/6 = ..................

* <em>Lets solve the problem</em>

- Rafael wanted to order half a medium pizza

- The medium pizza could be cut into 6 or 8 slices

∵ The half of 6 is 3/6

∵ The half of 8 is 4/8

- <em>Lets simplify the two fraction</em>

∵ 3/6 = 1/2 by dividing up and down by 3

∵ 4/8 = 1/2 by dividing up and down by 4

∴ There is no difference between the two orders, both of them

   equal half the pizza

∴ The wrong in Rafael reason is that 3/6 = 4/8 = 1/2 pizza

What are the odds in favor of choosing a person at random who chose juice a?
stealth61 [152]

37:53

Step-by-step explanation:

Step 1 :

Given

Number of people choosing Juice A = 37

Number of people choosing Juice B = 32

Number of people choosing Juice C = 21

We need to find the odds in favor of choosing a person who chooses juice A

Step 2  :

Here the number of success is the number of people choosing juice A = 37

Number of failures is the number of the people not choosing juice A = Number of people choosing juice B + Number of people choosing juice C = 32+21 = 53

Hence the odds in favor of choosing a person who chooses juice A is 37:53
