The author's message is that a person cannot predict the future without first learning about the past. The author does this by providing an example of how one wants to read without knowing the letters of the alphabet. Obviously, you can't read without first learning the letters of the alphabet. With the reading example, the author is explaining that just like a person trying to read without learning the alphabet first, a person predicting the future without knowing their history first is doing the exact same thing, it's nearly impossible.

What are polynomials?A polynomial is a mathematical equation made up of coefficients and indeterminate that can only be solved using the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
A polynomial exists as an expression consisting of indeterminate and coefficients, that concern only the processes of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
Vertical addition exists as s procedure of adding where the numbers are lined up in columns according to their place values. Likewise, vertical subtraction exists as a method of subtracting where the numerals exist lined up in columns according to their place values.

Mr. Trainer is building a bookcase. He has two wooden boards that are each 8 feet long. He needs to cut the wooden boards into pieces that are 16 inches long. What is the greatest number of 16-inch pieces that Mr. Trainer can cut from the two wooden boards? (1 foot = 12 inches)
Answer:
12
Step-by-step explanation:
Length of one of the boards = 8 feet
Converting to inches
[tex]1\ \text{foot}=12\ \text{inches}\\\Rightarrow 8\ \text{feet}=8\times 12=96\ \text{inches}[/tex]
One cut is 16 inches
So, we divide the length of the board by 16
[tex]\dfrac{96}{16}=6[/tex]
So, one board is cut into 6 pieces.
The other board is also 8 feet long.
So, the number of pieces the other board is cut into is also 6.
Hence, a total of [tex]6+6=12[/tex] pieces of each 16 inches long can be cut from the two boards.
Marilyn collects old dolls. She purchases a doll for $450. Research shows this doll's value will increase by 2.5% each year. Write an equation that determines the value, V, of the doll t after purchase.
Answer:
V = 450 + 0.025t
Step-by-step explanation:
What we know is that Marilyn purchases a doll for $450 dollars, and the value will increase by 2.5% each year. Now that we know this, this means we need an addition equation. We know 450 is being add to the 2.5% increase so the equation is V = 450 + 0.025t. (I put 2.5% as a decimal (0.025))
The equation that determines the value, V, of the doll (t) after purchase is [tex]V = 450 ({1.025}{} )^{t}[/tex]
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
What is compound interest?Compound interest is an interest accumulated on the principal and interest together over a given time period. The compound interest is calculated, after calculating the total amount over a period of time, based on the rate of interest, and the initial principal.
Formula of Compound Interest
[tex]A = P (1+\frac{r}{100} )^{n}[/tex]
Where,
A = Final amount
P = Initial principal
r = Rate per annum
n = Time in years
According to the question
Marilyn purchases a doll for = $450
i.e, Initial Principal (P) = $450
Doll's value will increase each year by = 2.5%
i.e, Rate per annum = 2.5%
Value (V) of the doll after purchase = Final amount (A)
(t) = Time in years (n)
Now, Formula of compound interest
[tex]A = P (1+\frac{r}{100} )^{n}[/tex]
Substituting the values in formula
[tex]V = 450 (1+\frac{2.5}{100} )^{t}[/tex]
[tex]V = 450 (1+{0.025}{} )^{t}[/tex]
[tex]V = 450 ({1.025}{} )^{t}[/tex].
Hence, equation that determines the value, V, of the doll (t) after purchase is [tex]V = 450 ({1.025}{} )^{t}[/tex]

What is the quotient of 2.592\times 10^72.592×10 7 and 7.2 \times 10^47.2×10 4 expressed in scientific notation?
The quotient, expressed in scientific notation, is:
Quotient = 0.36 × 10³
Given:
(2.592 × 10⁷) / (7.2 × 10⁴)
To find the quotient of 2.592 × 10⁷ and 7.2 × 10⁴ and express it in scientific notation, we divide the coefficients and subtract the exponents.
Quotient = (2.592 × 10⁷) / (7.2 × 10⁴)
Dividing the coefficients, we get:
Quotient = 2.592 / 7.2 = 0.36
Subtracting the exponents, we get:
10⁷ - 10⁴ = 10⁽⁷⁻³⁾ = 10³
In scientific notation, the coefficient should be between 1 and 10, so we can rewrite the expression as:
Quotient = 0.36 × 10³
