The profuct of the given expression (x-2)³ is (x³ - 6x² + 12x - 8).
What are expressions?An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division, etc.) You can think of expressions as being similar to phrases. Mathematical operators like addition, subtraction, multiplication, and division are used to create expressions in writing. For instance, the mathematical expression for "4 added to 2" will be 2+4.So, (x-2)³:

The difference between 75% of a number and 20% of the same number is 378.4 what is 40% of that number?
Answers
Answer:
40% of the number is 275.2.
Step-by-step explanation:
I am going to call the number x.
75% of the number: 0.75x
20% of the same number: 0.2x
The difference between 75% of a number and 20% of the same number is 378.4:
This means that:
0.75x - 0.2x = 378.4
0.55x = 378.4
x = 378.4/0.55
x = 688
40% of the number:
0.4*688 = 275.2
40% of the number is 275.2.

Answers
The output value of g( -5 ) in the function g( x ) = −23( x - 4 )2 + 3 is 417.
What is the output value of g(-5) in the given function?A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.
Given the data in the question;
g( x ) = −23( x - 4 )2 + 3g( -5 ) = ?To find the g( - 5 ), replace all the occurrence of x with -5 in the function and simplify.
g( x ) = −23( x - 4 )2 + 3
g( -5 ) = −23( -5 - 4 )2 + 3
g( -5 ) = −23( -9 )2 + 3
g( -5 ) = −23( -9 × 2) + 3
g( -5 ) = −23( -18) + 3
g( -5 ) = ( -23 × -18) + 3
g( -5 ) = ( 414 ) + 3

What are exponential power?A number's exponent demonstrates how many times we are multiplying a given number by itself. 34, for instance, indicates that we are multiplying 3 by four. 3333 is its expanded form. The power of an integer is another term for an exponent. A whole number, fraction, negative number, or decimal are all acceptable. How frequently a number is multiplied by itself is indicated by its exponent. As 2 is multiplied by itself 4 times, 2222 might be expressed as 24, for instance. The "base" in this case is 2 and the "exponent" or "power" is 4. The general definition of xn is "x multiplied by itself n times."

Answers
Given the following data set:
[13,13,13,15,15,16,16,17,17]
Let's determine the median.
Step 1: Arrange the data points from smallest to largest.
The set is already arranged in ascending order.
[13,13,13,15,15,16,16,17,17]
Step 2:
a.) If the number of data points is odd, the median is the middle data point in the list.
b.) If the number of data points is even, the median is the average of the two middle data points in the list.
There are 9 data in the set, it is odd. The middle data is the 5th data.
[13,13,13,15,15,16,16,17,17]
The 5th data is 15.
Therefore, the median of the given set of data is 15.
A box of cereal states that there are

-cup serving. What is the unit rate for calories per cup? How many calories are there in
4 cups of the cereal?
Answers
The unit rate for the cereal is 104 calories per cup and there are 416 calories in 4 cups
How to determine the unit rate for the cereal?From the question, the given parameters are
Calories = 78 calories
Size of cups = 3/4-cup
The unit rate of the calories per cup is calculated as
Unit rate = Number of Calories/Size of cup
Substitute the known values in the above equation
So, we have the following equation
Unit rate = 78/(3/4)
Evaluate the quotient
So, we have the following equation
Unit rate = 104
So, the unit rate is 104 calories per cup
For four cups of cereal, we have
Calories = 104 x 4
Evaluate
Calories = 416
So, the number of calories is 416 calories

How to check whether the value of x satisfies the equation?To check the value of x satisfies the equation, put the value of x and if it matches the resultant, it is correct.
Now solving the first part, x/4=20;x=5
So, putting x=5 in the equation 5/4=1.25 is not matching with the resultant ie. 20.
Therefore, this is the incorrect value of x.
Now solving the second part, 1.5x-8=7;x=10
So, putting x=10 in equation 1.5*10-8= 15-8=7
It matches with the resultant.
Therefore, this is the correct value of x.
Now solving the third part, 4x+6=58; x=13
So, putting x=13 in equation 4(13)+6= 52+6=58
It matches with the resultant.
Therefore, this is the correct value of x.

We want to find the expression that best represents the measure of the interior angle of a regular polygon with n sides.
The general formula for finding the total angle in a regular n sided polygon is given as:

B. (2, 3)
C. (5, 0)
D. (0, 3)
Answers
The point in the feasible region maximizes the objective function is (5, 0)
How to determine the feasible region?The given parameters are
Objective function: C = 7x - 3y
Subject to (i.e. the constraints)
x ≥ 0, y ≥ 0
y ≤ 1/5x + 2, 5 ≥ y + x
Next, we plot the graph of the constraints (see attachment)
This is done by entering the inequalities in a graphing calculator
From the graphing calculator, we have the feasible regions to be
(5, 0), (2.5, 2.5) and (0, 5)
Substitute (5, 0), (2.5, 2.5) and (0, 5) in the objective function: C = 7x - 3y
So, we have
(5, 0): C = 7(5) - 3(0)
C = 35
(2.5, 2.5): C = 7(2.5) - 3(2.5)
C = 10
(0, 5): C = 7(0) - 3(5)
C = -15
The value 35 is greater than 10 and -15
The coordinates at this value are (5, 0)
Hence, the coordinates is (5, 0)
