Answer:

105

Step-by-step explanation:

Work out the difference between the highest value and the lowest value in

the list:  -55, 45, -30, 25, -90

The lowest value will be the largest negative number in the list: -90

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

Hence, the solution is 20

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.

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

Therefore, the slope is 1 and equation of line is y = x + 1.

Using permutation and combination we can calculate that she can get 63 different types of pizza.

Permutations and combinations are the various ways in which elements from a set may be chosen, typically without replacement, to create subsets. This choice of subsets is known as a permutation when the order of the selection is taken into account, and as a combination when it is not.

The total of the decisions we make given an initial set of n items is known as a combination. Permutation, on the other hand, counts the number of possible arrangements of n separate items. This will help us recall that combinations place more emphasis on choice than on placement, order, or arrangement.

Now Cody can get any two toppings out of the 7.

Number of ways in which Cody can pick 2 toppings out of 7 is given by the use of combination,

7C2 = 21 different ways.

Again the number of ways in which 3 different pizza s can be selected is given by 21 × 3 = 63 ways.

The equation that can be use to find the how many miles, x, Omar ran each day after work is x =  (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7, he ran 6 miles each days  after work

The total number of days he run = 7 days

Total distance he ran in one week = 63 miles

The distance he run before the work = 3 miles

The total distance he run before the work in one week= 7×3

= 21 miles

The total distance he run after the work = 63 - 21

= 42 miles

The equation that can use to find how many mile x, Omar ran each day after work = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7

Substitute the values in the equation

Answer:

1.  3 and -5

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]

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

Therefore, the zero of the function is 7 (with multiplicity 2).

The following results of the quadratic equation are summarized below:

Vertex: (h, k) = (3, 1)

Axis of symmetry: x = 3

Min/Max value: f(3) = 1 (Maximum)

y-Intercept: - 8

x-Intercepts: (2, 0), (4, 0)

Domain: All real numbers.

Range: y ≤ 1.

Sketch of the graph: Please see image.

Standard form: f(x) = x² - 6 · x + 8

Rigid transformations: Horizontal translation / Reflection about x-axis / Vertical translation

In this problem we have a quadratic equation in standard form, whose definition is shown below:

f(x) - h = C · (x - h)²        (1)

Where:

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

Since the vertex constant is negative, the range of the quadratic equation is the subset of all real numbers equal or less than the y-value of the vertex.

Sketch of the graph

Please check the image attached below to see the graph.

Standard form

The standard form of the quadratic equation is:
