SOLUTION
Problem Statement
The question gives us an expression to simplify and we are to simplify by finding the product. We are also asked to find the degree of the polynomial as well
Method
We simply need to expand the bracket to solve this question. But the degree of the polynomial is gotten by assessing which term in the final expression has the highest power. If the expression has a term with its highest power being 3, then the degree of the polynomial is 3.
With this information, let us begin solving.
Implementation
1. Expanding the expression:
Expanding the polynomial, we have:
[tex]\begin{gathered} (8n-4)(n^2+9) \\ \text{ Using the FOIL method,} \\ F=8n(n^2)=8n^3 \\ O=8n(9)=72n \\ I=-4(n^2)=-4n^2 \\ L=-4(9)=-36 \\ \\ \therefore(8n-4)(n^2+9)=8n^2+72n-4n^2-36 \\ \\ \text{ Remember, we are asked to write this result in descending order of terms. Thus, we have that:} \\ 8n^3-4n^2+72n-36 \end{gathered}[/tex]2. Degree of the polynomial:
From the above result, we can see that the highest degree of n in all the terms is 3, therefore, the degree of the polynomial is 3
Final answer
[tex]\begin{gathered} \text{ Question 1:} \\ 8n^3-4n^2+72n-36 \\ \\ \text{Qusetion 2:} \\ \text{THE DEGREE OF THE POLYNOMIAL IS 3} \end{gathered}[/tex]

You will purchase snacks for the painting class. You have abudget of $40. You want to buy fruit and granola bars. Fruit costs $4 perpound, and the granola bars are $1 each. You need at least 20 granolabars. What combinations of fruit and granola bars can you buy?My variables- f-fruits g-granola
Answers
Budget: $40
Fruit: $4/pound
Granola bars: $1 each
At least 20 granolas
Let's call
f: number of pounds of fruit
g: number of granola bars
Therefore
The total cost of fruit is given by: $4 · f
The total cost of granola is given by: $1 · g
The total cost of everything is given by: $4 · f + $1 · g
Since budget: $40 then
$4 · f + $1 · g = $40
4f + g = 40
g > 20 means we have at least 20 granolas
4f + g > 20 means that we have at least 20 granolas, that cost $20, since 4f + g = 40 and 40 > 20
Find the minimum value of
C = 6x + 3y
Subject to the following constraints:
x > 1
y ≥ 1
4x + 2y < 32
2x + 8y < 56
Answers
Answer:
9
Step-by-step explanation:
You want the minimum value of objective function C=6x+3y, given the constraints x>1, y≥1, 4x+2y<32, and 2x+8y<56.
MinimumThe objective function has positive coefficients for both x and y, so it will be minimized when x and y are at their minimum values. The constraints tell you these minimum values are x=1 and y=1, so the minimum value of C is ...
C = 6(1) +3(1) = 9
The minimum value of C is 9.
__
Additional comment
The value of x cannot actually be 1, so the value of C cannot actually be 9. However x may be arbitrarily close to 1, so C may be arbitrarily close to 9.
C = 6x +3y ⇒ x = (C -3y)/6
The x-constraint requires ...
x > 1
(C -3y)/6 > 1
C -3y > 6 . . . . . . multiply by 6
C > 6 +3y . . . . . . add 3y
The minimum value of y is exactly 1, so we have ...
C > 6 +3(1)
C > 9

Enter an inequality that represents the graph in the box.
Answers
The inequality that represents the graph is (1/4)x - y + 3/2 ≤ 0.
What is inequality?An inequality compares two non-qual objects.
We know the general equation of a line is ax + by + c = 0.
From observation, we can conclude that the given line has points (0, -6) and (2, 2).
∴ The slope of the line is [tex]\frac{y_2 - y_1}{x_2- _ x_1}[/tex].
= (0 - 2)/(-6 - 2).
= -2/-8.
= 1/4.
∴ Equation of the line in slope intercept form y = mx + b.
2 = (1/4)(2) + b.
2 = 1/2 + b.
b = 3/2.
∴ Equation of the line is y = 1/4(x) + 3/2.
(1/4)x - y + 3/2 = 0 but the region will be (1/4)x - y + 3/2 ≤ 0.

A textbook store sold a combined total of 217 sociology and history textbooks in a week. The number of history textbooks sold was 77 less than the number of
sociology textbooks sold. How many textbooks of each type were sold?
Answers
Answer:
there were 246 chemistry textbooks and 169 psychology textbooks sold
Step-by-step explanation:
Let
c = the number of chemistry textbooks sold
p = the number of psychology textbooks sold
a textbook store sold a combined total 415 chemistry and psychology textbooks in a week
c + p = 415
the number of chemistry textbooks sold was 77 more than the number of psychology textbooks sold
c = 77 + p
by solving the system of equations
c + p = 415
c = 77 + p
we find
c = 246 chemistry textbooks
p = 169 psychology textbooks

Explain why the volume of these two stacks of quarters are equal? Use Cavaliens principle in your explanation (If you need to)
Answers
Given the word problem, we can deduce the following information:
1. Two stacks of 18 pennies each are shown.
To determine if the volumes of the given stacks of quarters are equal, we note that Cavelieri's Principle states:
The volumes of two solids are equal if the areas of the corresponding sections drawn parallel to some given plane are equal.
Since each penny in both stacks has the same base area and has the same number of pennies. Therefore, the volumes of the given stacks are equal.

The statement that is equivalent to 1, 0 0 0, 0 0 0 is: C. 10 power of 6.
Determining the equivalent numberGiven digit:
1,0 0 0,0 0 0
Hence,
When something is equivalent to another things it implies or means that both of them are the same or correspond.
We know that 1,000,000 can be re- write as 1 Million and 1000 Thousands.
Now let determine or find the equivalent of 1,000,000 using scientific notation
Scientific notation = 1,000,000
Scientific notation = 10^6
Based on the above 10^6 is equivalent to 1,000,000. We can justified it by pressing 10^6 on our calculator which will in turn gives us 1,000,000.
So,
1,000,000 = 10^6
Therefore we can conclude that the correct option is C based on the fact that 10 raise to power of 6 is the same as 1,0 0 0,0 0 0.

How many hooks can he expect to use if he needs to catch 189 fish?
Answers
By solving a proportional relation, we conclude that he needs 81 hooks to catch 189 fish.
How many hooks can he expect to use if he needs to catch 189 fish?We assume there is a proportional relationship of the form:
F = k*H
where:
F = number of fish.k = constant of proportionality.H = number of hooks.We know that with 3 hooks he catches 7 fish, then we can replace that:
7= k*3
7/3 = k
So the proportional relation is:
y = (7/3)*x
Then if he wants to get 189 fish we can write:
189 = (7/3)*x
And solve this for x:
189*(3/7) = x =81
He will need 81 hooks.

Answers
The numeric value for the given expression is as follows:
[tex]\frac{j(x + h) - j(x)}{h} = \frac{4^{x - 2}(4^h - 1)}{h}[/tex]
How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function by the desired value.
In the context of this problem, the function j(x) is given as follows:
[tex]j(x) = 4^{x - 2}[/tex]
At x = x + h, the numeric value of the function is found replacing the lone instance of x by x + h as follows:
[tex]j(x + h) = 4^{x + h - 2}[/tex]
For the fraction, the subtraction at the numerator is given as follows, applying properties of exponents:
[tex]j(x + h) - j(x) = 4^{x + h - 2} - 4^{x - 2} = 4^{x - 2}(4^h - 1)[/tex]
As the x - 2 term is common to both exponents.
Just dividing by h, the numeric value of the entire expression is given as follows:
[tex]\frac{j(x + h) - j(x)}{h} = \frac{4^{x - 2}(4^h - 1)}{h}[/tex]
Which means that the third option is correct.

Answers
Given:
A table represents a survey to know if residents would like a dog.
a) What is an appropriate first step in finding the experimental probability that a household has 2 or more dogs?
The first step is to find the total households
So, the answer will be option C
Find the sum of the number of households for each category.
b) What is the experimental probability that a household has 2 or more dogs?
First, the total number of households = 513 + 218 + 129 = 860
And the number of households has 2 or more dogs = 129
So, the probability = 129/860 = 0.15 = 15%
