Answer:

Step-by-step explanation:

Volume is length times width times height. Because our shape is a cube, by definition, all the sides are the same length, so we are multiplying the number by itself 3 times...we are cubing it. The power then is 3. If we cube 1/3

[tex](\frac{1}{3})^3[/tex] which is [tex]\frac{1}{27}[/tex]

Given:

The equation is:

[tex]x^2-12x+32=4[/tex]

To find:

The result of completing the square for the given equation.

Solution:

We have,

[tex]x^2-12x+32=4[/tex]

It can be written as:

[tex]x^2-12x=4-32[/tex]

[tex]x^2-12x=-28[/tex]

Now, we need to add half of square of coefficient of x, to complete the square.

Adding [tex](\dfrac{-12}{2})^2[/tex] on both sides, we get

[tex]x^2-12x+(\dfrac{-12}{2})^2=-28+(\dfrac{-12}{2})^2[/tex]

[tex]x^2-2(x)(6)+(-6)^2=-28+(-6)^2[/tex]

[tex]x^2-2(x)(6)+(6)^2=-28+36[/tex]                 [tex][\because (-a)^2=(a)^2][/tex]

Using the formula [tex](a-b)^2=a^2-2ab+b^2[/tex], we get

[tex](x-6)^2=8[/tex]

Therefore, the required equation after completing the square is [tex](x-6)^2=8[/tex].

Step-by-step explanation:

[tex]sin^{-1} (sin17^{0} )[/tex] = [tex]17^{0}[/tex]

The inverse sine function (also called arcsine) is the inverse of sine function. Since sine of an angle (sine function) is equal to ratio of opposite side and hypotenuse, thus sine inverse of same ratio will give the measure of the angle.

sin ([tex]sin^{-1}x[/tex]) = x, whenever x ∈ [-1, 1] and

sin ([tex]sin^{-1}x[/tex]) is NOT defined whenever x ∉ [-1, 1].

Given

[tex]sin^{-1} (sin17^{0} )[/tex]

Cancel out [tex]sin^{-1}[/tex] and sin

[tex]sin^{-1} (sin17^{0} )[/tex] = [tex]17^{0}[/tex]

It's the second answer down : Angle B, A and C

Step-by-step explanation:

The sequence from the smallest to the largest is angle B, angle A, angle C .

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given AB= 22 units

BC=16 units

AC=12 units

The property of Triangle says, in a triangle, angle opposite to the greater side have greater angle.

That is angle opposite to the shorter side have shorter angle.

Therefore, we have

Therefore,

angle opposite to side AC is angle B,

angle opposite to side BC is angle A,

angle opposite to side AB is angle C,

Therefore, the sequence from the smallest to the largest is angle B, angle A, angle C .

Answer:

121/4

Step-by-step explanation:

To complete the square, we have to work with the coefficient of x

We have to divide the coefficient of x by 2, square it and add it to both sides

So we divide 11 by 2; which is 11/2; then square it

we have this as 121/4

Answer:

549 pumps

Step-by-step explanation:

We'll begin by calculating the radius of the larger ball. This can be obtained as follow:

Circumference (C) = 71

Pi (π) = 3.14

Radius (r) =?

C = 2πr

71 = 2 × 3.14 × r

71 = 6.28 × r

Divide both side by 6.28

r = 71 / 6.28

r = 11.3 in

Next, we shall determine the volume of the larger ball.

Since a ball is spherical in shape, we shall use the formula for calculating the volume of a sphere to obtain the volume of the ball. This can be obtained as follow:

Pi (π) = 3.14

Radius (r) = 11.3 in

Volume (V) =?

V = 4/3πr³

V = 4/3 × 3.14 × 11.3³

V = 4/3 × 3.14 × 1442.897

V = 6041 in³

Finally, we shall determine the number of pumps will it take to fill the large soccer ball. This can be obtained as follow:

11 in³ = 1 pump

Therefore,

6041 in³ = 6041 in³ × 1 pump / 11 in³

6041 in³ = 549 pumps

Thus, it will take approximately 549 pumps of air to fill the large soccer ball.

Answer:

Answer:

x=0, y=-2

Step-by-step explanation:

Because 9y appears twice in both equations, you can subtract the equations to eliminate the y variable so you can solve for x:

-7x + 9y = -18

-(4x + 9y = -18)

__________

-11x = 0

x = 0

Since we know x=0, then we plug it back into one of the equations to get the value of y:

-7x + 9y = -18

-7(0) + 9y = -18

0 + 9y = -18

9y = -18

y = -2

Therefore, x=0, and y=-2
