Please answer my question by the way the number 4 and 5 is FOIL.
Using FOIL method for the multiplication, we have:
1: 3x (5x - 4) = 15x² - 12x
2: x²(5x² + 3y + 1) = 5x⁴ + 3x²y + x²
3: (4x + 3)(4x -5) = 16x² - 8x - 15
4: (7x - 3)(4x - 5) = 28x² - 47x + 15
How to carry out multiplication using FOIL?
FOIL is an acronym that stands for "First, Outer, Inner, Last". It is a mnemonic device that is commonly used to remember the process of multiplying two binomials.

The set S:{42} will make the inequality false.
By definition, one can apply any monotonically rising function to both sides of an inequality without affecting how they relate to one another (provided that both expressions are in the domain of that function).
An inequality relation would be reversed if a monotonically dropping function were applied to both sides of the inequality. Examples of how to employ a monotonically declining function are the rules for the additive and multiplicative inverses for positive values. The inequality (a b, a > b) remains stringent if the function is monotonic in a strict sense.If only one of these requirements is met, the inequality that results is not rigid. In fact, the requirements for both additive and multiplicative inverses serve as evidence that a strictly.Given inequality is :
3/8 m - 9 < 1/4 m + 2
Solving the inequality we get:
or, m < 40

False
First you have to know what a natural number is.
They are all the integers from 1 to infinity.
Naturally they are closed for addition. 3 + 9 = 12. You can make as many examples as you like. You will not get anything outside the natural numbers.

It takes 2 ounces of paint to completely cover all 6 sides of a rectangular prism box which holds 15 cups of sugar. Double the dimensions of the box. Approximately how much paint would be needed to cover the box? How much sugar would it hold?
The amount of paint needed if the dimensions are doubled is; 8 ounces.
The quantity of sugar which the rectangular prism would hold if the dimensions are doubled is; 120 cups of sugar.
What quantity of sugar would the prism hold when the dimensions are doubled?Recall,
Area of a rectangular prism = 2 (lw + lh + wh) and
Volume of a rectangular prism = l × w × h.
Hence, when the dimensions are doubled;
New Area = 2 × 4 (lw + lh + wh) = 4 × initial area.
Therefore, the quantity of paint needed is; 4 × 2 ounces = 8 ounces of paint.
Also, when the dimensions are doubled;
New Volume = 2l × 2w × 2h = 8 lwh.
New Volume = 8 × initial volume = 8 × 15 cups = 120 cups of sugar.

What is the equation of the line that passes through the point (6,14) and is parallel to the line with the following equation? y=-4/3x -1
Answer:
\(y=\displaystyle-\frac{4}{3}x+22\)
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: \(y=mx+b\) where m is the slope and b is the y-interceptParallel lines always have the same slope (m)Determine the slope (m):
\(y=\displaystyle-\frac{4}{3}x -1\)
The slope of the given line is \(\displaystyle-\frac{4}{3}\), since it is in the place of m in y=mx+b. Because parallel lines always have the same slope, the slope of a parallel line would also be \(\displaystyle-\frac{4}{3}\). Plug this into y=mx+b:
\(y=\displaystyle-\frac{4}{3}x+b\)
Determine the y-intercept (b):
\(y=\displaystyle-\frac{4}{3}x+b\)
To find the y-intercept, plug in the given point (6,14) and solve for b:
\(14=\displaystyle-\frac{4}{3}(6)+b\\\\14=-8+b\\b=22\)
Therefore, the y-intercept of the line is 22. Plug this back into \(y=\displaystyle-\frac{4}{3}x+b\):
\(y=\displaystyle-\frac{4}{3}x+22\)

2. Oil is leaking from an uncapped well and polluting a lake. Ten days after the leak is discovered, environmental engineers measure the amount of oil in the water to be 200 gallons with a current inflow rate of 30 gallons per day. The leak is slowing so that on the tenth day, the inflow rate is decreasing by 5 gallons/day each day. Suppose Q(t) is the amount of oil (in gallons) t days after the leak is discovered. (a) Find the second degree Taylor polynomial for Q(t) centered at t=10. (b) Use your answer in the previous part to estimate the amount of oil in the lake at t=12
As a result, 210 gallons of oil are thought to have been present in the lake at time 12 (t=12).
what is polynomial ?A polynomial is a mathematical equation that only uses addition, subtraction, multiplication, and non-negative integer exponents and is made up of variables and coefficients. To put it another way, a polynomial is an algebraic expression made up of terms that are sums, products, and/or products of variables and coefficients. The leading coefficient is the coefficient of the term with the highest degree, while the degree of a polynomial is the maximum power of the variable in the expression.
given
(a) We need to determine Q(10), Q'(10), and Q" in order to determine the second degree Taylor polynomial for Q(t) with a center at t=10 (10).
As we are aware, Q(10) = 200. (given in the problem statement).
We must take the derivative of Q(t) with respect to t in order to determine Q'(10):
Q'(t) = -5t + 250
Q'(10) = -5(10) + 250 = 200
We must take the derivative of Q'(t) with respect to t in order to determine Q"(10):
Q''(t) = -5
Q''(10) = -5
The second degree Taylor polynomial can now be calculated using the following formula: P2(t) = Q(10) + Q'(10)(t-10) + (1/2)Q"(10)(t-10)2.
With the numbers we discovered, we can calculate P2(t) as 200 + 200(t-10) + (1/2)(-5)(t-10)2.
\(P2(t) = 200 + 200(t-10) - (5/2)(t-10)^2\)
(b) We must assess the second degree Taylor polynomial at t=12 in order to determine how much oil is in the lake at that time.
P2(12) = 210 gallons because P2(12) = 200 + 200(12-10) - (5/2)(12-10)2. (rounded to the nearest gallon)
As a result, 210 gallons of oil are thought to have been present in the lake at time 12 (t=12).

if the temperature of the turducken is 150 after half an hour, what is the temperature after 45 minutes
If the temperature of the turducken is 150° after half an hour, the temperature of the turducken after 45 minutes is 225 degrees.
To determine the temperature of the turducken after 45 minutes, we first need to establish the rate at which the temperature is changing.
Find the temperature change after half an hour (30 minutes)
The given temperature after 30 minutes is 150 degrees.
Calculate the rate of temperature change per minute
Temperature change / time = 150 degrees / 30 minutes = 5 degrees/minute
Determine the temperature after 45 minutes
Since the temperature increases by 5 degrees every minute, we need to find the temperature increase for an additional 15 minutes (45 minutes - 30 minutes = 15 minutes).
Temperature increase for 15 minutes = 5 degrees/minute * 15 minutes = 75 degrees
Add the temperature increase to the initial temperature
Temperature after 45 minutes = 150 degrees (initial temperature) + 75 degrees (increase) = 225 degrees
Therefore, the temperature of the turducken after 45 minutes is 225 degrees.

2. Estimate a 15% tip for each amount
$9. 89 for lunch.
please help on these problems
1) The total amount you will pay for the game is approximately $43.03. 2)For a lunch bill of $9.89, a 15% tip would amount to approximately $1.48.
To calculate the total amount you will pay for the game after applying taxes, you need to calculate the city tax and state tax separately. For the city tax of 0.5%, you can multiply the purchase price of $39.99 by 0.005, which gives $0.19995 (rounded to $0.20). Next, for the state tax of 7.25%, you can multiply the purchase price by 0.0725, which gives $2.899275 (rounded to $2.90).
Adding the city tax and state tax to the purchase price: $39.99 + $0.20 + $2.90 = $43.09. Rounded to two decimal places, the total amount you will pay for the game is approximately $43.03.
To estimate a 15% tip for a lunch bill of $9.89, you can multiply the bill amount by 0.15. Doing so, you get $9.89 × 0.15 = $1.4835 (rounded to $1.48). Therefore, a 15% tip for a lunch bill of $9.89 would amount to approximately $1.48.

the half life of radium is 1690 years if 8 grams are present now how many grams will be present in 100 years
So, approximately 7.71 grams of radium will be present after 100 years.
To calculate the remaining amount of radium after 100 years, we will use the half-life formula:
Remaining Amount = Initial Amount * (1/2)^(time passed / half-life)
Here, the initial amount is 8 grams, the half-life is 1690 years, and the time passed is 100 years.
Step 1: Plug in the values
Remaining Amount = 8 * (1/2)^(100 / 1690)
Step 2: Calculate the exponent
Exponent = 100 / 1690 ≈ 0.05917
Step 3: Calculate the base raised to the exponent
(1/2)^0.05917 ≈ 0.9634
Step 4: Multiply the initial amount by the base raised to the exponent
Remaining Amount = 8 * 0.9634 ≈ 7.7072
So, approximately 7.71 grams of radium will be present after 100 years.
