Answer:

√3/3

Step-by-step explanation:

Multiply the numerator and denominator by the conjugate.

Hope this helps!! Please consider marking brainliest! Have a good one!!

Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the denominator.

If the radical in the denominator is a square root, then you multiply by a square root that will give you a perfect square under the radical when multiplied by the denominator.   If the radical in the denominator is a cube root, then you multiply by a cube root that will give you a perfect cube under the radical when multiplied by the denominator and so forth...

Note that the phrase "perfect square" means that you can take the square root of it.  Just as "perfect cube" means we can take the cube root of the number, and so forth.  

Keep in mind that as long as you multiply the numerator and denominator by the exact same thing, the fractions will be equivalent.

Step 2: Make sure all radicals are simplified.

Some radicals will already be in a simplified form, but make sure you simplify the ones that are not.  If you need a review on this, go to Tutorial 39: Simplifying Radical Expressions.

Step 3: Simplify the fraction if needed.

Be careful.  You cannot cancel out a factor that is on the outside of a radical with one that is on the inside of the radical.  In order to cancel out common factors, they have to be both inside the same radical or be both outside the radical.

Answer:

Step-by-step explanation:

If on the coordinate map, ice cream is located at the point (-8,0) and sprinkles are located at the point (-8,6), we can find the distance between the coordinate points using the formula;

D = √(x2-x1)²+(y2-y1)²

Given

x1 = -8, y1 = 0, x2 = -8 and y2 = 6

Substitute

D = √(x2-x1)²+(y2-y1)²

D = √(-8-(-8))²+(6-0)²

D = √0²+6²

D = √36

D = 6units

Hence the distance between the coordinate points is 6units

Given:

(2, 4) and (3, 3) are on the line.

To find:

The equation of line in point slope form.

Solution:

If a line passes through a point [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is

[tex]y-y_1=m(x-x_1)[/tex]

(2, 4) and (3, 3) are on the line. So, slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{3-4}{3-2}[/tex]

[tex]m=\dfrac{-1}{1}[/tex]

[tex]m=-1[/tex]

The slope of a line is -1 and it passes through (2,4). So, an equation in point slope form is

[tex]y-4=-1(x-2)[/tex]

Therefore, an equation of the line in point slope form is [tex]y-4=-1(x-2)[/tex].

Answer:

right triangle

Step-by-step explanation:

10 + 24 = 34

34 > 26

Therefore, there is a triangle.

Now we use the Pythagorean theorem.

10^2 + 24^2 = 100 + 576 = 676

26^2 = 676

Since 10^2 + 24^2 = 26^2, the triangle is a right triangle.

1, 5, 25,  125

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by

5 gives the next term. In other words,  an=a1⋅rn−1. Geometric Sequence: r=5

This is the form of a geometric sequence.an=a1rn−1 Substitute in the values of a1=1 and r=5.an=(1)⋅(5)n−1 Multiply (5)n−1 by 1. an=5n−1

Answer:

<6 and 4 are supplementary angles. Supplementary angles add up to 180. therefore <6 and <4=180--->m<6=65---->180-65=115--->   m<4-115

2. 115°

By using vertical angles theorem we see that angles opposite to each other like 5 and 8 are congruent.

Therefore m<8 = m<5

3. 122

<3 and <6 are congruent by the alternate interior angles theorem which states that interior angles that are opposite one another such as 6 and 3 are congruent.

4. 73°

<4 and <7 are supplementary since the <4 is equal to the <8 and the <8 is supplementary to 7.

180-107=73

Answer:

m = 0

Step-by-step explanation:

4. m = 0

Answer:

y = 2/3x + 1 1/3

Step-by-step explanation:

Find the slope using rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(2 - 0) / (1 + 2)

2 / 3

= 2/3

Then, plug in the slope and a point into y = mx + b to solve for b:

y = mx + b

2 = 2/3(1) + b

2 = 2/3 + b

1 1/3 = b

Plug in the slope and y intercept into y = mx + b

y = 2/3x + 1 1/3 is the equation of the line

Answer:

Carlos tiene razón. El poliedro es un cubo.

Step-by-step explanation:

Comencemos analizando el número de caras del dodecaedro y del cubo.

El dodecaedro está conformado por 12 caras.

El cubo en cambio, está conformado por 6 caras.

En cuanto a aristas el dodecaedro tiene 30 aristas y en cambio el cubo tiene 12. Por ende, descartamos la idea de que el poliedro sea un dodecaedro.

Finalmente en cuanto a vértices, el dodecaedro tiene 20 vértices y el cubo tiene 8 vértices.

Si sumamos el número de caras y el número de vértices en el cubo obtenemos :

6 + 8 = 14

Con esto, verificamos que la figura borrosa es de un cubo y que Carlos tiene razón.

Given :

Devin is buying 2 concert tickets. The concert tickets have a regular price of $40 each.

Devin has a coupon that gives a 5% discount off of the regular price of the tickets. He will then pay a 10% purchasing fee on the discounted price of the tickets.

To Find :

Devin's total cost of the two tickets after the discount and the fee.

Solution :

Discount on price, D = 40×0.05 = $2 .

Price of product after discount, P = $( 40 - 2 ) = $38 .

Now, total price after adding purchasing fee is :

T = P + (P×0.10)

T = 38 + (38×0.10)

T = 38 + 3.8

T = $41.8

Therefore, Devin's total cost of the two tickets after the discount and the fee is $41.8 .

Hence, this is the required solution.
