Mrs. Brady purchased an item on sale and described her purchase to her students. Four students each wrote an expression to represent the cash Mrs. Brady paid for the item, in dollars, given an original price of P and the use of a five dollar gift card to help pay for the purchase. Their expressions are shown in the table below.
The variable terms in all four expression indicates that the item was on 25% off.
The expressions with more terms indicate a different sale price than the expressions with fewer terms.
The constant term in each expression indicates the original price of the item Mrs. Brady purchased.
The constant term in each expression indicates that the sale price is not dependent on the original price of the item.
The constant term in each expression indicates the amount deducted when the gift card was applied to the purchase.
The variable terms in all four expressions indicate that the item was on sale of 25 percent off.

Expand each binomial.
(9-2 x)⁵
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. (9 - 2x)⁵ is expanded as 59049 − 65610x + 29160x² − 6480x³ + 720x⁴ − 32x⁵.
What is meant by binomial expansion theorem?The Binomial theorem tells us how to expand expressions of the form (a + b)ⁿ, for example, (x + y)⁷. The larger the power is, the harder it is to expand expressions like this directly.
The total number of terms in the expansion of (x+y)ⁿ are (n+1).
The sum of exponents of x and y is always n.
nC₀, nC₁, nC₂, … .., nCₙ are called binomial coefficients and also represented by C₀, C₁, C₂, ….., Cₙ
The binomial coefficients which are equidistant from the beginning and from the ending are equal.
i.e. nC₀ = nCₙ, nC₁ = nCₙ₋₁ , nC₂ = nCₙ₋₂ ,….. etc.
Let the function be (9 - 2x)⁵
By using binomial expansion theorem, we get
(9 - 2x)⁵ = 59049 − 65610x + 29160x² − 6480x³ + 720x⁴ − 32x⁵.
(9 - 2x)⁵ is expanded as 59049 − 65610x + 29160x² − 6480x³ + 720x⁴ − 32x⁵.

rewrite the equation in standard form (y=ax^2+bx+c)
y=3(x-5)^2 +1
please show and explain steps, thanks
It should be noted that rewriting the equation y=3(x-5)² +1 in another form is y = 3x² - 30x + 76.
How o illustrate the information?It should be noted that the information is that we should rewrite the equation y=3(x-5)² +1 in another form.
This will be illustrated as:
y = 3(x-5)² + 1.
It should be noted that (x - 5)² will be:
= (x - 5)(x - 5)
= x² - 5x - 5x + 25
= x² - 10x + 25
y = 3(x-5)² + 1.
y = 3(x² - 10x + 25) + 1
y = 3x² - 30x + 75 + 1
y = 3x² - 30x + 76
In conclusion, it should be noted that rewriting the equation y=3(x-5)² +1 in another form is y = 3x² - 30x + 76.

31.4 rounded to the nearest tenth of a centimeter
Answer: 31.4
Step-by-step explanation:
the four is in the tenth place and we are rounding to that place.
The given decimal number is rounded to the nearest tenth as 31.4.
The given decimal number is 31.4.
Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
Here, in 31.40 digit in the hundredths place is 0, which is less than 5.
So, the digit in the tens place remain same and digits after tens place becomes zero.
That is, 31.4
Therefore, the given decimal number is rounded to the nearest tenth as 31.4.

Which function is a phase shift of y=sin \theta by 5 units to the left?
(A) y=5 sinθ (C) y=sin (θ+5)
(B) y=sinθ+5 (D) y=sin 5 θ
Answer:
C.
Step-by-step explanation:
C describes theta moving +5 units. In math, negative goes left, negative goes left. However, since there are no negative values involved, we can assume that theta will move 5 units to the left in terms of absolute value, which excludes the need for the negative to be moved left. Therefore, the answer is C due to this change.

A proportion is an equation based on the equality of two ratios.
Here it is given that :
To avoid a storm, a passenger-jet pilot descended 0.14 mile in 0.4 minute and it is to find the plane's average change of altitude per minute and to find that we divide 0.14 miles with 0.4 minutes it will give us the descended
passenger-jet pilot does in a minute that is plane's average change of altitude :
In 0.4 minute = 0.14 miles descended
In 1 minute = 0.14/0.4 miles descended
In 1 minute = 0.35 miles descended

A factory produces 100 units of a certain product and 6 of them are defective. If three units are picked at random then what is the probability that at least one of them is defective?.
The probability that at least one of them is defective if three units are picked at random is 0.8560.
We would define Ai as the event that the i th chosen unit is not defective, for I = 1, 2, 3. We are interested in P (A1 ∩ A2 ∩ A3). Note that
P(A1) = 95/100
Given that the first chosen item was good, the second item will be chosen from 94 good units and 5 defective units, thus
P (A2 ∣ A1) = 94/99
Given that the first and second chosen items were okay, the third item will be chosen from 93 good units and 5 defective units, thus
P (A3∣ A2, A1) = 93/98
Thus, we have
P(A1∩ A2 ∩ A3) = P(A1) P(A2∣ A1) P(A3∣ A2, A1)
=95/100*94/99*93/98

What is the substitution property of equality?
The substitution property of equality refers to when a value is replaced in an equation with another value that are same or equal to the first. say AA is being used in an equation and another value say BB, replaces AA in the equation. In this case we say that AA is being substituted for BB in the equation

Write each expression as a single natural logarithm. 4 ln 8+ln 10
Expression as a single natural logarithm is ln 64/64 = ln 1.
ln 1 is the converted from 2 ln 8-3 ln 4 to a single natural logarithm.
We need to convert 2 ln 8-3 ln 4 as a single natural logarithm.
First apply power property
⇒ ln 8² - ln 4³
⇒ ln 64 - ln 64
Now, applying quotient property
⇒ ln 64/64 = ln 1
Here, we finally converted 2 ln 8-3 ln 4 to a single natural logarithm ln 1.
What is natural logarithm?The inverse of an exponential function, the natural log is the logarithm to the base of the number e. Natural logarithms are unique varieties of logarithms that are employed in the treatment of time and growth-related issues.
The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e. As an illustration, log of base 2 is denoted by log2 and log of base e by loge = ln (natural log).
