Is the simplified form of 2 v3 · 2 v6 rational?

Mathematics
1 answer:
tatuchka [14]3 years ago
5 0

Answer:

No

Step-by-step explanation:

2√3 × 2√6

= 4√18

= 4√9*2

= 4( 2√2)

= 8√2

Just multiply the numbers under the radical together.  √3 × √6 = √18.  √18 can be written as √9*2, or 3√3.

√2 is irrational, so the answer will be irrational

Answer:   x < 2

<u>Step-by-step explanation:</u>

2x + 1 < 5

Subtract 1 from both sides:

2x < 4

Divide both sides by 2:

x < 2     <em>(x is less than 2)</em>

This week laptops are 25% off. If a laptop costs $340, what is its sale price?
Alexandra [31]

____________________________________________________

Answer:

Your answer would be $255

____________________________________________________

Step-by-step explanation:

To solve these kind of problems, what we have to do is find how much of 340 is 25%, and then subtract that number to the original price.

Let's give you some important information in the text:

  • 25% off
  • $340

With the information above, we can solve our problem.

First, we would need to find how much of 340 is 25%, and to do that, we would multiply 340 by 0.25:

340*0.25 = 85

When you solve, you should get 85. But, you're not done yet, we need to find out how much the sales price is, not how much of it is discounted.

In order to find the sales price, we would get our original number (the number it originally cost), and subtract it with the amount of money it's removing (85).

In this case, we would subtract 340 by 85.

340-85=255

Your FINAL answer should be 255

The sales price of the laptop would be $255.

Write an equation passing through the point and perpendicular to the given line: (-3,5);y = 3/4x-4
balandron [24]

Hey!

So the first thing we realize is that it says that the equation is perpendicular to the line, meaning that the slope of the line is the negative reciprocal of the slope of the line you are given. Since we are given the slope of this line as 3/4 we can take the negative reciprocal of this to get -(4/3).

Now that we have the slope and a point on the line you can plug those into the equation y = mx + b to find b. The slope of the line is m and the point contains the x and y values.

5 = -(4/3)(-3) + b

5 = 4 + b

1 = b

Since we have the y-intercept and the slope now we can plug that into the slope-intercept form equation to get the equation we need:

y = -(4/3)x + 1

Mohammad would like to graph the line that represents the total number of baseball cards he will
Marina CMI [18]

Answer:

To best show this information, the scale for the T-axis of his graph should go from 0 to at least 60.

To best show this information, the scale for the m-axis of his graph should go from 0 to at least 12.

Step-by-step explanation:

Mohammad will have collected T cards after m months, given that he buys 5 cards each month and he started with no cards.

The relationship describing this situation is

T=5m

When m=6, then T=5\cdot 6=30 cards.

When m=12, then T=5\cdot 12=60 cards.

To best show this information, the scale for the T-axis of his graph should go from 0 to at least 60.

To best show this information, the scale for the m-axis of his graph should go from 0 to at least 12.
