Answers

Answer:

n=64

Step-by-step explanation:

Let think algebracially. One of the terms in the set is a fraction. A natural number must be a whole number so this means that

n must be a multiple of 8.

*N must be a multiple of 8.

Look at the third term, we know that a square root must produce a perfect square term to get a natural number. So n must be a multiple of 8 that makes the radical a perfect square

Perfect squares are.

0,1,4,9,16,25,36,49,64,81,100,121,144,169,196,225, 256, 289

N has to compute a sum greater than 225 so the perfect squares we look at must be greater than 225.

The next one is 256 but

[tex]256 - 225 = 31[/tex]

[tex]31 \div 8 = \frac{31}{8} [/tex]

which isn't rational so 256 won't work. Let try 289

[tex]289 - 225 = 64[/tex]

[tex]64 \div 8 = 8[/tex]

and

[tex]33 + 64 = 97[/tex]

So 64 works. 64 is the answer

n=64

To work this out you need the denominator to be the same. So, you multiply 2/5 by 2 which equals 4/10.

4/10 + 4/10 = 8/10

show that a^12 can be written as a perfect square and a perfect cube

Answers

Answer:

Step-by-step explanation:

Doing this the long way, write a^12 as a product of "a"s

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

Now group them into groups of 4

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube

Now do the same thing with groups of 6s

a^12 = a * a * a * a * a * a * a * a * a * a * a * a

a^12 = (a^6)^2

So the two answers are

Perfect cube:  [(a^4)]^3

Perfect square: (a^6)^2

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $9 monthly fee and charges an additional $0.17 for each minute of calls. The second plan has a $24 monthly fee and charges an additional for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?

Answers

Answer:

88.23

Step-by-step explanation:

The equation for the first plan is:

9 + 0.17x

The equation for the second plan is

24

Then you set the two equations equal to each other

9 + 0.17x = 24

Subtract on both sides

0.17x = 15

Find the value of 4w +1 given that -3w-7=2.
Simplify your answer as much as possible.

Answers

Answer:

-11

Step-by-step explanation:

-3w - 7 = 2

-3w (- 7 + 7) = 2 + 7

-3w = 9

-3w/-3 = 9/-3

w = -3

4w + 1

4(-3) + 1

-12 + 1

-11

Answer:

4w + 1 = -11

Step-by-step explanation:

Solving -3w - 7 = 2

By adding 7 to both sides of the equation  we get -3w = 9

to get to w = ... we need to divide both sides with -3, which gives us

w = -3. You can check this answer by putting it back into the original equation ( -3 * -3 - 7 does equal 2,  which means our solution for w is correct.

Now all we have to do is put our solution for w into the remaining equation:

4 * -3 + 1 = -12 + 1 = -11

Aaron took a taxi from his house to the airport. The taxi company charged a pick-up fee of $2 plus $3.50 per mile. The total fare was $58, not including the tip. Which equation could be used to determine xx, the number of miles in the taxi ride?

Answers

Answer:

58 = 3.5x + 2

Step-by-step explanation:

Since $3.50 is charged for every mile, we multiply x by 3.5 like this: 3.5x

$2 is already added on as a free so + 2

$58 is the total amount of money for all of the charges including the per mile and pick-up fee.

This was we can solve for the number of miles, x

58 = 3.5x + 2

- 2            - 2

56 = 3.5x

56/3.5 = 3.5x/3.5

x = 16

The taxi drove a total of 16 miles

[tex]607200 * 0.000189393939 = 114.9999997608[/tex]

cos(4*x) = cos(3*x)^2+sin(x)^2

Answers

Recall the following identities:

cos(4x) = cos⁴(x) - 6 cos²(x) sin²(x) + sin⁴(x)

cos(3x) = cos³(x) - 3 cos²(x) sin(x)

sin²(x) = 1 - cos²(x)

Then the equation

cos(4x) = cos²(3x) + sin²(x)

can be rewritten entirely in terms of cos(x) as

8 cos⁴(x) - 8 cos²(x) + 1 = 16 cos⁶(x) - 24 cos⁴(x) + 8 cos²(x) + 1

16 cos⁶(x) - 32 cos⁴(x) + 16 cos²(x) = 0

16 cos²(x) (cos²(x) - 1)² = 0

Now we can solve:

cos²(x) = 0   or   (cos²(x) - 1)² = 0

cos(x) = 0   or   cos²(x) - 1 = 0

cos(x) = 0   or   cos²(x)  = 1

cos(x) = 0   or   cos(x) = -1   or   cos(x) = 1

x = π/2 + 2   or   x = -π/2 + 2

…   or   x = π + 2

…   or   x = 2
