the order of the surd 6 √2187 after simplification is​

Answers

Answer:

[tex]n = 162[/tex]

Step-by-step explanation:

Given

[tex]6\sqrt{2187[/tex]

Required

Determine the order of the surd

If a surd is represented as [tex]n\sqrt{r[/tex], then the order of the surd is [tex]n[/tex]

[tex]6\sqrt{2187[/tex]

Express 2187 as [tex]3^6 * 3[/tex]

[tex]6\sqrt{2187} = 6\sqrt{3^6 * 3}[/tex]

Split the surd

[tex]6\sqrt{2187} = 6\sqrt{3^6} * \sqrt{3}[/tex]

Apply the following law of indices:

[tex]\sqrt{a} = a^{\frac{1}{2}}[/tex]

The expression becomes:

[tex]6\sqrt{2187} = 6 * 3^{\frac{6}{2}} * \sqrt{3}[/tex]

[tex]6\sqrt{2187} = 6 * 3^{3} * \sqrt{3}[/tex]

[tex]6\sqrt{2187} = 6 * 27 * \sqrt{3}[/tex]

[tex]6\sqrt{2187} = 162 * \sqrt{3}[/tex]

[tex]6\sqrt{2187} = 162 \sqrt{3}[/tex]

By comparing [tex]162 \sqrt{3}[/tex] to [tex]n\sqrt{r[/tex], we can say that:

[tex]n = 162[/tex]

[tex]r = 3[/tex]

Conclusively, the order of the surd is 162

Answers

Answer:

The answer is 286.

Explanation:

We first find the first term of the sequence, a₁. We use the explicit formula for an arithmetic sequence to do this:

We know the 6th term is 22; this means we substitute 6 in for n. We also know the common difference is 6, so we use that for d. That gives us a₆=a₁+6(6-1).

We know the value of the sixth term is 22, so we use that instead of a₆:

22=a₁+6(6-1).

Evaluating this, we have

22=a₁+6(5)

22=a₁+30.

Subtract 30 from both sides, and we have

22-30=a₁

-8=a₁.

We now use this value in our explicit formula:

To find the fiftieth term we replace n with 50:

a₅₀= -8+6(50-1)

a₅₀= -8+6(49)

a₅₀= -8+294

a₅₀=286

Answer:  10x - 1

==============================================

Explanation:

The multiplicative inverse of x is 1/x, and vice versa. This is true as long as x is not 0.

The multiplicative inverse of 1/5 is 5. These two values multiply to 1. This is true of any multiplicative inverse pairing.

----------

What we need to do is multiply 5 with (2x-1/5)

Use the distributive property to get the following

5*(2x-1/5)

5*(2x) - 5*(1/5)

10x - 5/5

10x - 1

I multiplied the outer 5 by each term inside (the 2x and 1/5) and simplified.

180 - 94 = 86

So all the inside angles of a triangle = 180

180 - 86 - 60 = 34

34/2 = 17

Answer:

it's answer is 17

Step-by-step explanation:

we know exterior angle of a triangle is equal to the sum of two opposite interior angles. So,

2x + 60° = 94°

2x = 94° - 60°

2x = 34°

x = 34° /2

x = 17°

Solve the following equation, -2(x-2)=4 for x. Show your work please

Answers

Answer:

x = 0

Step-by-step explanation:

Divide by -2

-2(x - 2)/-2 = 4/-2

x - 2 = - 2        

Add 2 to both sides

x - 2 + 2 = - 2 + 2

x = 0

Answer:

x = 0

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: -2*(x-2)-(4)=0

This is how your equation should look like (0 -  2 • (x - 2)) -  4  = 0

Solve: -2x = 0

Multiply both sides of the equation by (-1) :  2x = 0

Divide both sides of the equation by 2:  x = 0

Step-by-step explanation:

As two lines are parallel, their slope is same which is -6

Now, use:y-y1=m(x-x1)

y-(-4)= -6(x-0) (y1=-4,x1=0, cause the equation of y axis is x=0)

Which boat was farther from the dock at the beginning and which traveled more quickly

Answers

Answer:

Nvm

Step-by-step explanation:

Johns boat was 30 miles away. It traveled 20 miles in 5 hours (50-30 = 20)

20/5 = 4

It traveled at 4 miles per hour.

The equation for Roberta’s boat multiplied 5 by x( number of hours) so this means her boat is traveling at 5 miles per hour.

Then 25 gets added at the end, this means her boat was 25 miles away at the beginning.

Johns boat was further away at the beginning and Robertas boat is traveling faster.
