The length of the edge of the box is 6 cm.

Here, we are given that the volume of a box is 216 cm cube.

Here, we assume that the box is a cube and not a cuboid since only then we will be able to find the edge of the box.

The volume of a cube is given by the formula-

Volume = side × side × side

Let the side of the given cube be x.

Then we can form the following equation-

[tex]x^{3}[/tex] = 216

x = (216)^1/3

we can find the 216 is the cube of 6. Thus,

x = 6

Hence, the length of the edge of the box comes out to be 6 cm.

By solving a simple linear equation, we will get that:

36° = m∠AOB

We can write a simple linear equation here, we know that:

m∠AOC = 108°

And we also know that:

m∠AOC = 3*m∠AOB

If we replace the first equation into the second one, then we will have the linear equation:

108° = 3*m∠AOB

And we want to solve this for m∠AOB, to do so, we just need to divid both sides by 3, we will get:

108°/3 = m∠AOB

36° = m∠AOB

We conclude that the measure of angle ∠AOB is 36°

The integer in the solution set of 5/6m - 4 < 1/3m + 5 that would make it false is 20

The set is given as

S:{−18, 2, 15, 20}

The inequality expression is given as

five sixths m minus four is less than one third m plus 5

Rewrite the inequality expression properly

So, we have

5/6m - 4 < 1/3m + 5

Subtract 1/3m from both sides of the inequality expression

So, we have

1/2m - 4 < 5

Add 4 to both sides of the inequality expression

So, we have

1/2m < 9

Divide both sides of the inequality expression hy 1/2

So, we have

m < 18

This means that the integers in the solution set are integers that are less than 18

These integers are −18, 2, 15

All other integers would make the inequality false

Step-by-step explanation:

The value of x is 67°.

To determine the value of x,

Draw a line parallel to lines l and m passing through the vertex at angle x dividing it into two angles a and b.

∠a  = 35°   (Interior Alternate angles are congruent)

∠b + 148°  = 180°  (Co-Interior angles are supplementary)

2.  7

Step-by-step explanation:

The zeros of functions are the x-values when y = 0, i.e the point(s) at which the line crosses the x-axis.

To find the zeros of the given functions, set the function to zero and solve for x.

Given function:

[tex]y=5(x-3)(x+5)[/tex]

Set the function to zero:

[tex]\implies 5(x-3)(x+5)=0[/tex]

[tex]\implies \dfrac{5(x-3)(x+5)}{5}=\dfrac{0}{5}\\[/tex]

[tex]\implies (x-3)(x+5)=0[/tex]

Using the Zero Product Property, set each factor equal to zero and solve for x:

[tex]\implies (x-3)=0 \implies x=3[/tex]

[tex]\implies (x+5)=0 \implies x=-5[/tex]

Therefore, the zeros of the function are 3 and -5.

Given function:

[tex]y=(x-7)^2[/tex]

Set the function to zero and solve for x

[tex]\implies (x-7)^2=0[/tex]

[tex]\implies \sqrt{(x-7)^2}=\sqrt{0}[/tex]

[tex]\implies x-7=0[/tex]

Now we proceed to determine each of the required features:

Vertex

The quadratic equation has a vertex at point (3, 1).

Axis of symmetry

The axis of symmetry of the parabola is x = 3.

Min/Max value

For as the vertex constant is a negative number, then the vertex represents a maximum. Then, we evaluate the function at x = 3:

f(3) = 1

y-Intercept

The y-intercept is the value of the quadratic equation evaluated at x = 0.

f(0) = - (0 - 3)² + 1

f(0) = - 9 + 1

f(0) = - 8

x-Intercepts

The x-intercepts are the values of x such that f(x) = 0, all these can be found by using algebra properties:

- (x - 3)² + 1 = 0

- (x² - 6 · x + 9) + 1 = 0

- x² + 6 · x - 9 + 1 = 0

x² - 6 · x + 8 = 0

(x - 2) · (x - 4) = 0

Then, the x-intercepts of the parabola are (2, 0) and (4, 0).

Domain

The domain of all quadratic equations are all real numbers.

Range

Using a proportional relationship, we have that:

A direct proportional relationship is a function in which the output variable is found with the multiplication of the input variable and the constant of proportionality k, as follows:

y = kx.

From the table in this problem, the constant is given as follows:

k = 240/5 = 48/1 = 48.

Hence the relationship is:

y = 48x.

Then:

For 300 pencils, the number of boxes is given by:

48x = 300

x = 300/48

x = 6.25.

There are not decimal parts of a box, a complete box is needed, hence 7 boxes are needed, meaning that 6 boxes are not enough for 300 pencils.

In this question, we have been given an equation of parabola 2x² − 8y = 0

We need to graph the parabola and identify the axis of symmetry, focus, and directrix.

2x² - 8y = 0

2x² = 8y

x² = 8y/2

x² = 4y

The graph of the parabola  x² = 4y is as shown below.

From this graph, the vertex is (0, 0)

We know that, for a parabola of the form x² = 4ay, the focus is (0, a) and directrix is y = -a

For the parabola  x² = 4y, a = 1

So, the focus is (0, 1) and the directrix is y = -1

And the axis of symmetry for the parabola x² = 4y is the y-axis.

The slope and equation of line with the coordinates (5,6) and (3,4) are 1 and y = x + 1 respectively.

Slope is simply expressed as change in y over the change in x.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Given the data in the question;

Point A(5,6)

Point B(3,4)

Slope m = ?

To determine the slope, plug the given coordinates into the slope formula and simplify.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 4 - 6 )/( 3 - 5 )

Slope m = ( -2 )/( -2 )

Slope m = ( -1 )/( -1 )

Slope m = 1/1

Slope m = 1

Next, use the the formula for the equation of line to determine the y-intercept 'b'.

y = mx + b

Plug in slope m = 1 and point (5,6)

6 = 1(5) + b

6 = 5 + b

b = 6 - 5

b = 1

Now that we have both the slope m ( 1 ) and y-intercept b ( 1 ), plug these values into y = mx + b to find the linear equation.

y = mx + b

y = 1x + 1

y = x + 1
