X(1/6+1/18)=1

X(3/18+1/18)=1

X(4/18)=1

X(2/9)=1

Answer:The area is 14306. 625 cm.

Step-by-step explanation:

To find the area of the circle, we will need to find the diameter and find the radius.

So we know the circumference is  423.9 m and we know to get the circumference, you will need to multiply pie by the diameter .

so now we need divide the circumference by pie to find the diameter.

423.9/ 3.14 = 135  so 135 is the diameter.

To find the radius we need to divide the diameter by 2.

135/2 = 67.5

Now is time to find the area which uses the formula  A= nr^2

A = 3.14 * 67.5^2

A = 14306. 625

Answer:

a) 2nd container is more efficient and contains the elements for a container.

b) The cylinder has a........A)Smaller surface area B)bigger C)equal

And will cost.....A)Less to produce B)more C)The same

Step-by-step explanation:

a) The 2nd container has these elements:

Width 20.5cm

Length 6.5cm

side 3.25cm

So, the volume in cubic cm is 20.5 x 6.5 x 3.25 = 433cm3.

This container can hold the 300cm3 of juice.

b) A cylinder is a geometric solid common in everyday life.  Examples of a cylinder are soup cans, food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders.  The two ends are called bases, and are usually circular.  Though, they can take other shapes.  When a cylinder is unrolled and flattened out, the side is actually a rectangle.

The surface area of a cylinder is the surface area of each end plus the surface area of the side.  The mathematical formula is 2π * r2, where π is the pie and r is the radius of the end and r2 is r squared..

The product of the given expressions will be 84x¹²

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression, 4x(-3x⁸)(-7x³) we need to find the product of the same,

So, the product is =

4x(-3x⁸)(-7x³)

= 4x × (-3x⁸) × (-7x³)

= 4 · x · (-3) · x⁸ · (-7) · x³

= 4·21·x⁽¹⁺⁸⁺³⁾

= 84x¹²

Hence, the product of the given expressions will be 84x¹²

Answer:

3

Step-by-step explanation:

Well first let's calculate how many times she jumped per hour. For that we need to divide 42 by 7 which is 6. Now we need to divide that by two because they are asking for every half hour, not every hour. So 6 divided by 2 is 3. So our answer is 3.

Answer:

I think the perimeter is 8 yd

Step-by-step explanation:

Because it's a square, if one side is 2 yd then we can assume that the remaining 3 sides are also 2 yd long. So, 2 yd + 2 yd + 2 yd + 2 yd =  8  yd

Answer:

75.36

Step-by-step explanation:

The circumference of a circle is just the diameter, 24 in this question times 3.14.

The solution is, 75.36 cm is the circumference, in centimeters, of the circle.

A perimeter can be mentioned as a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

Perimeter means to the total outside length of an object,

here, we have,

the diameter, 24 cm (in this question)

now, we have to find the circumference,

we know that,

The circumference of a circle is the diameter times 3.14.

so, we get,

the circumference = 24*3.14 cm

                               =75.36cm

Hence, The solution is, 75.36 cm is the circumference, in centimeters, of the circle.

Answer:

about 9.4 units

Step-by-step explanation:

Distance formula:

√(x1 - x2)² + (y2 - y1)²

Coordinates:

A (4, 2)

B (9, 10)

Let's make 9 = x1

Let's make 4 = x2

Let's make 10 = y1

Let's make 2 = y2

Substitute into the distance formula:

√(x1 - x2)² + (y2 - y1)²

√(9 - 4)² + (2 - 10)²

Solve:

√(9 - 4)² + (2 - 10)²

√(5)² + (-8)²

√25 + 64

√89

≈ 9.4

Therefore, the length of AB is approximately 9.4 units.

Answer:

About 9.4 units

Step-by-step explanation:

To find the distance between two points

d = sqrt(( y2-y1) ^2 + (x2-x1) ^2)  where (x1,y1) and (x2,y2) are the points

   =  sqrt(( 10-2)) ^2 + (9-4) ^2)

   =  sqrt((8) ^2 + (5) ^2)

   = sqrt(64+ 25)

    = sqrt(89)

   =9.433981132

About 9.4 units

Answer:

The area of the sector is [tex]180\pi \ cm^2[/tex].

Step-by-step explanation:

We have,

Radius of circle is 15 cm

Central angle is [tex]\dfrac{8\pi}{5}\ \text{radian}[/tex]

It is required to find the area of the sector. The formula used to find the area of sector is given by :

[tex]A=\dfrac{1}{2}r^2\theta[/tex]

Plugging all the values in above formula as :

[tex]A=\dfrac{1}{2}\times 15^2\times \dfrac{8\pi}{5}\\A=180\pi \ cm^2[/tex]

So, the area of the sector is [tex]180\pi \ cm^2[/tex].

Answer:

The Flower Garden is not in the shape of a right Δ

Step-by-step explanation:

~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~

Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;

a^2 + b^2 = c^2,

10^2 + 7^2 = 13^2,

100 + 49 = 169,

149 ≠ 169,

So the Flower Garden will not be in the shape of a right Δ

Answer:

The final transformed function becomes:

[tex]f(x)=-3\,|x-2|+4[/tex]

Step-by-step explanation:

The first transformation (vertically stretched by a factor of 3) means we multiply by 3 the original function:

[tex]f(x)= 3\,|x|[/tex]

second transformation (shifted left 2 units) means we add 2 units to "x":

[tex]f(x)=3\,|x+2|[/tex]

third transformation (shifted down 4 units) implies that we subtract 4 units to the full functional expression:

[tex]f(x)=3\,|x+2|-4[/tex]

fourth transformation (reflected over the x-axis) implies that we multiply the full functional expression by "-1":

[tex]f(x)=(-1)\,(3\,|x+2|-4)\\f(x)=-3\,|x-2|+4[/tex]

Step-by-step explanation:

Step 1:  Add the vertical stretch

[tex]f(x) = |x|[/tex]

[tex]f(x) = 3|x|[/tex]

Step 2:  Shift it to the left 2 units

[tex]f(x) = 3|x|[/tex]

[tex]f(x) = 3|x + 2|[/tex]

Step 3:  Shift it down 4 units

[tex]f(x) = 3|x + 2|[/tex]

[tex]f(x) = 3|x + 2| - 4[/tex]

Step 4:  Reflect it across the x-axis

[tex]f(x) = 3|x + 2| - 4[/tex]

[tex]f(x) = -3|x + 2| - 4[/tex]

Answer:  [tex]f(x) = -3|x + 2| - 4[/tex]
