Answer:

[tex](D)x^{3/4}y^{1/2}[/tex]

Step-by-step explanation:

We are required to simplify the expression: [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})[/tex]

This is a product and the first thing we will do is to collect like terms:

[tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{1/2}x^{1/4}y^{1/3}y^{1/6}[/tex]

Next, we apply the addition law of indices: [tex]x^a X x^b =x^{a+b}[/tex]

[tex]x^{1/2}x^{1/4}y^{1/3}y^{1/6}=x^{1/2+1/4}y^{1/3+1/6}\\\\=x^{3/4}y^{1/2}[/tex]

Therefore, [tex](x^{1/2}y^{1/3})(x^{1/4}y^{1/6})=x^{3/4}y^{1/2}[/tex]

The whiskers range from 2 to 11, and the box ranges from 4 to 9. A line divides the box at 7. A box-and-whisker-plot. The number line goes from 0 to 11. The whiskers range from 2 to 11, and the box ranges from 5 to 8. a line divides the box at 7.  

Step-by-step explanation:

Even though both data sets have the same median (7) they don't have the same variability because they have different quartiles 1, quartiles 3 and interquartile range.

Answer:

x = 5

Step-by-step explanation:

Two secants from an external point to a circle, then the product of one secant's external part and the entire secant is equal to the product of the external part and the entire secant of the other, that is

(x - 2)(x - 2 + x + 4) = 4(4 + 5)

(x - 2)(2x + 2) = 4(9) = 36 ← distribute and simplify the left side

2x² + 2x - 4x - 4 = 36

2x² - 2x - 4 = 36 ( subtract 36 from both sides )

2x² - 2x - 40 = 0 ( divide through by 2 )

x² - x - 20 = 0 ← in standard form

(x - 5)(x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 4 = 0 ⇒ x = - 4

But x > 0 ⇒ x = 5

Create a stack where the 6-inch-by-8-inch faces of the blocks touch is the correct  strategy for stacking the blocks

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The block has the following dimensions:

( L x w x h ) = ( 8 x 5 x 6 ) in

We will determine the surface area of each unique face of the block given in the attachment.

Surface area of the face ( 8 x 5 ):

Area = ( 8 )×( 5 )

Area = 40 in²

Surface area of the face ( 8 x 6 ):

Area = ( 8 )×( 6 )

Area = 48 in²

Surface area of the face ( 6 x 5 ):

Area = ( 5 )×( 6 )

Area = 30 in²

Hence, Create a stack where the 6-inch-by-8-inch faces of the blocks touch is the correct  strategy for stacking the blocks

Answer:

The missing data value is 147

Step-by-step explanation:

The mean is 120

The standard deviation is 9

Missing data value = ?

From the question, the missing data value is 3 standard deviation away from the mean.

3 standard deviation = 3 * 9 = 27

3 standard deviation from the mean = 120 + 27 = 147

The missing data value is what we get after adding 3 standard deviation from the mean.

Step-by-step explanation:

The volume of pearl is 39 cubic millimeters, if A necklace has a single pearl with a radius of 2.1 millimeters.

Step-by-step explanation:

The given is,

                   Pearl with a radius of 2.1 millimeters

Step:1

                   Pearl shape general looks like a sphere,

                   Volume of sphere,

                                                 [tex]V= \frac{4}{3}r^{3}[/tex]...............................(1)

                  Where, r - Radius of sphere

                  From the given values,

                                         r - 2.1 millimeters

                  Equation (1) becomes,

                                                    [tex]= \frac{4}{3}\pi (2.1)^{3}[/tex]

                   Substitute the value of [tex]\pi[/tex],

                                                    [tex]= (1.33333333)(\frac{22}{7} ) (9.261)[/tex]          ( ∵ [tex]\pi = \frac{22}{7}[/tex] )

                                                    [tex]=(4.190476)(9.261)[/tex]  

                                                    = 38.79

                                                    ≅ 39 cubic millimeters

                   Volume of pear, V = 39 cubic millimeters    

Result:

             The volume of pearl is 39 cubic millimeters, if A necklace has a single pearl with a radius of 2.1 millimeters.

Answer:

Considering the equation given:

[tex]y= 3x -2[/tex]

As a function:

[tex]f(x)= 3x -2[/tex]

[tex]$(2, -1)$[/tex] states for [tex](x, y)[/tex], which means, [tex]x=2[/tex] and [tex]y=-1[/tex]

[tex]f(2)= 3(2) -2\\f(2)= 6-2\\f(2)= 4[/tex]

[tex]4\neq -1[/tex]

Therefore, [tex]$(2, -1)$[/tex] is not a solution for the equation given and for the function.

Final answer:

To determine if (2,-1) is a solution of Y = 3X - 2, we substitute x=2 into the equation and simplify. The resulting y-value does not match the y-coordinate of the point, therefore (2,-1) is not a solution.

Explanation:

To verify whether the point (2,-1) is a solution to the equation Y = 3X - 2, we need to substitute the x-value of the point (2) into the equation and see if the resulting y-value equals the y-value of the point (-1). If they match, then the point is a solution of the equation.

Let's go through the step-by-step process:

Since the calculated y-value (4) does not equal the y-coordinate of the point (-1), the point (2,-1) is not a solution of the equation Y = 3X - 2.

The area of a circle is πr². We know r is 7, so the area is π * 7² = 49π.

Substituting, we have 49 * 3.14 = 153.86, which rounds to 153.9 centimeters squared.

The area of circle with a radius of 7 cm is,

⇒ 153.9 centimeters squared

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

Radius of circle = 7 cm

Now, We know that;

Area of circle is,

A = πr²

Where, 'r' is radius of circle.

Here, Radius of circle = 7 cm

Hence, The area of circle with a radius of 7 cm is,

⇒ A = πr²

⇒ A = 3.14 × 7²

⇒ A = 3.14 × 49

⇒ A = 153.9 centimeters squared

Thus, The area of circle with a radius of 7 cm is,

⇒ 153.9 centimeters squared

Step-by-step explanation:

We want to solve the equation,

[tex] \cos(x + 45) + \cos(x - 45) = \sqrt{2} [/tex]

We expand using trigonometric identities to get;

[tex]\cos(x) \cos( 45) - \sin(x) \sin(45) + \cos(x) \cos( 45) + \sin(x) \sin(45) = \sqrt{2} [/tex]

[tex] \frac{ \sqrt{2} }{2} \cos(x) - \frac{ \sqrt{2} }{2} \sin(x) + \frac{ \sqrt{2} }{2} \cos(x) + \frac{ \sqrt{2} }{2} \sin(x) = \sqrt{2} [/tex]

Simplify;

[tex] \cos(x) - \sin(x) + \cos(x) + \sin(x) = 2[/tex]

Simplify;

[tex]\cos(x) + \cos(x) = 2[/tex]

Add

[tex]2\cos(x) = 2[/tex]

Divide by 2

[tex]\cos(x) = 1[/tex]

Take cosine inverse;

To find out how much money you have left after riding each ride once, subtract the total cost of all the rides from the amount of money you have. To find out if you have enough money to ride each ride twice, multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have.

a. To determine how much money you have left if you ride each ride once, you need to know the cost of each ride. Let's say each ride costs $3. To find out how much money you have left, you subtract the total cost of all the rides ($3 x number of rides) from the amount of money you have. So, in this case, you have $15 - ($3 x number of rides) left.

b. To determine if you have enough money to ride each ride twice, you multiply the cost of each ride by 2 and check if it is less than or equal to the amount of money you have. So, if each ride costs $3, you would calculate $3 x 2 = $6 to see if it is less than or equal to $15.
