We want to divide 4x³ + 2x - 3 by x - 3 with the long division method
First, we rewrite the polynomial as:
4x³ + 0x² + 2x - 3
Them we divide the first term of the dividend by the highest term of the divisor:
4x²
x - 3 |4x³ + 0x² + 2x - 3
Then we multiply the divisor by this result:
| 4x²
x - 3 |4x³ + 0x² + 2x - 3
4x³ - 12x²
Now we subtract this result from the dividend:
| 4x²
x - 3 |4x³ + 0x² + 2x - 3
4x³ - 12x²
|12x² + 2x - 3
Now we can repeat all the previous steps using the last result as dividend:
| 4x² + 12x
x - 3 | 12x² + 2x - 3
12x² - 36x
|38x - 3
And we repeat these steps once more:
4x² + 12x + 38
x - 3 | 38x - 3
34x - 102
|99
The final term is the remainder
Then, we have:
4x³ + 2x - 3 = (x - 3)*(4x² + 12x + 34) + 99
Scott took out a 72 month
loan for $35,000 to purchase
a new boat. If Scott paid
$8,925 in simple interest,
what was the interest rate?
The interest rate paid by Scott is 4.25% for the 72 months.
We can determine the simple interest of the given problem by the simple interest formula which is given as :
I=PRT
Where,
I=Interest
P=principal
R=rate in decimal
T=time in years
Converting the given 72 months into years we get time t :
1 year = 12months
72 months / 12months = 6 years
t=6
From the given data
I=8925
P=35000
R=r
T=6
Substituting the above values in the simple interest equation we get:
8925 = 35000*r*6
8925 = 210000*r
divide both sides by 210000
R = 0.0425
Therefore, the interest rate is 4.25%

The graph below represents a recent 10 meter race between two remote control cars.
A graph titled Remote Control Car Race has seconds after race start on the x-axis and distance from start line (meters) on the y-axis. A line labeled red car goes through (3, 2) and (6, 4). A line labeled blue car goes through (3, 0) and (5, 2).
Which statements about the race are true? Check all that apply.
The red car won the race because it started above the blue car.
The cars crashed at 9 seconds into the race because that is the point of intersection, and neither car continued on after that point in time.
The blue car passed the red car at 6 m into the race because that is the point of intersection, and the blue car has a greater distance than the red car after that time.
The blue car is faster because the slope of its line is steeper than the slope of the line representiong the red car.
The blue car started 3 seconds late because it has an x-intercept of (3, 0) and x represents the time and y represents the distance from the starting line.

In linear equation, 9 is the constant of variation k.
What in mathematics is a linear equation?
An algebraic equation with simply a constant and a first-order (linear) component, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Equations with variables of power 1 are referred to be linear equations. axe+b = 0 is a one-variable example in which a and b are real numbers and x is the variable.
given x varies inversely with y then
xy = k ← k is the constant of variation
to find k use the condition x = - 4 when y = - 9, hence
k = -4 × -9 = 36
x = 36/y
when x = 4 , then y = 36/4

A fair number cube is labeled with the numbers 1 – 6. After rolling the cube 100 times, which would be most likely to occur? Responses The number 6 would never be rolled. The number 6 would never be rolled. All the numbers rolled would be odd. All the numbers rolled would be odd. An even number would be rolled 50 times. An even number would be rolled 50 times. The number 7 would be rolled at least once. The number 7 would be rolled at least once.
The outcome that is most likely to occur after rolling the cube 100 times is that an even number would be rolled around 50 times.
What is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.
A fair number cube labeled with the numbers 1 - 6 is equally likely to land on any of its faces when rolled.
Therefore, we can use probability to determine which outcome is most likely to occur after rolling the cube 100 times.
"The number 6 would never be rolled." This outcome is highly unlikely, but not impossible.
If the cube is fair, each number has an equal probability of being rolled, so the probability of rolling a 6 on any given roll is 1/6.
The probability of rolling a non-6 on any given roll is 5/6. The probability of not rolling a 6 in 100 rolls is (5/6)¹⁰⁰, which is approximately 0.0001. So, while it is very unlikely that the number 6 would never be rolled, it is not impossible.
"All the numbers rolled would be odd." This outcome is even less likely than the first one.
The odd numbers on the cube are 1, 3, and 5, each with a probability of 1/2.
The probability of rolling an odd number on any given roll is 1/2.
The probability of rolling an odd number on 100 rolls is (1/2)¹⁰⁰, which is an extremely small number, approaching zero.
"An even number would be rolled 50 times." This outcome is more likely than the first two.
The even numbers on the cube are 2, 4, and 6, each with a probability of 1/2.
The probability of rolling an even number on any given roll is 1/2.
If we assume that each roll is independent of the others, the probability of rolling an even number exactly 50 times in 100 rolls can be calculated using the binomial distribution and is approximately 0.0796.
This means that this outcome is not very likely, but still possible.
"The number 7 would be rolled at least once."
This outcome is impossible since the cube is only labeled with the numbers 1 through 6.
Therefore, the number 7 cannot be rolled.
Hence, Based on the above analysis, the outcome that is most likely to occur after rolling the cube 100 times is that an even number would be rolled around 50 times.

Find an equation of a line of best fit shown in the figure given below.
Answer:
C
Step-by-step explanation:
So you can use two points on the line to find the gradient. I used K and G. B and D could've been easily eliminated since the line goes through the origin (0,0) so there's no y - intercept or b value.
M = (Y-y)/(X-x)
M = (8-4)/(14-7)
M = 4/7
And the equation of a line is y = mx + b. There's no b so it's just y = (4/7)x
A square poster has an area measure of 324x^2 + 540x + 225 square units. Determine the side length of the poster.
\(\huge\text{$(18x+15)$ units}\)
Given the area, we need to find the side length. Let's start with the area equation for a square, where \(s\) is the side length and \(A\) is the area.
\(s^2=A\)
Substitute in the known value.
\(s^2=324x^2+540x+225\)
Now we need to factor the trinomial. The trinomial given for the area is a perfect square trinomial since \(324\) (\(18^2\)) and \(225\) (\(15^2\)) are both perfect squares.
We also know that \(a^2+2ab+b^2=(a+b)^2\), which we can use to factor.
\(s^2=324x^2+540x+225\\s^2=(18x)^2+2(18x)(15)+15^2\\s^2=(18x+15)^2\)
Now, take the square root of both sides to fully isolate \(s\).
\(\sqrt{s^2}=\sqrt{(18x+15)^2}\)
Keep in mind that the square root of any value squared is the original value.
\(s=\boxed{18x+15}\)
let C be the curve y=5sqrtx for 1.1

We have,
To find the surface area of the revolution about the x-axis of the function f(x) = 5√x over the interval (1.1 to 4.4), we can use the formula for the surface area of revolution:
S = ∫(a to b) 2πy√(1 + (f'(x))²) dx
In this case,
f(x) = 5√x, so f'(x) = (d/dx)(5√x) = 5/(2√x).
Let's calculate the surface area:
S = ∫(1.1 to 4.4) 2π(5√x)√(1 + (5/(2√x)²) dx
Simplifying the expression inside the integral:
S = ∫(1.1 to 4.4) x 2π(5√x)√(1 + 25/(4x)) dx
Next, we can integrate this expression over the given interval (1.1 to 4.4) to find the surface area.

To simplify the calculation, let's simplify the expression inside the integral first:
S = 2π ∫(1.1 to 4.4) (5√x)√((4x + 25)/(4x)) dx

Un bloque de vidrio flint tiene un espesor de 4 cm, ¿qué espesor aparenta tener cuando se le ve desde arriba?
Answer: El índice de refracción del vidrio flint es mayor que el del aire. Cuando la luz pasa de un medio con un índice de refracción menor (como el aire) a un medio con un índice de refracción mayor (como el vidrio), experimenta un cambio de dirección. Este fenómeno se conoce como refracción.
Cuando observamos el bloque de vidrio flint desde arriba, la luz que proviene del bloque sufre refracción al pasar del vidrio al aire. Debido a la refracción, los rayos de luz se desvían y parecen venir de una posición más alta dentro del vidrio de lo que realmente están. Esto crea una ilusión óptica que hace que el espesor aparente del bloque de vidrio se vea más delgado de lo que realmente es.
La cantidad exacta de adelgazamiento aparente depende del ángulo de incidencia de la luz y de los índices de refracción del vidrio y el aire. Sin más información, no es posible determinar el espesor aparente específico del bloque de vidrio flint cuando se ve desde arriba.

how many baskets must he fill?
c) Write an algebraic expression to
describe the relationship.
Answer:
Graph is attached
144 baskets
\(y=2.5x\)
Step-by-step explanation:
Let y be the total amount of money Gilbert earns and x be the number of baskets filled. So, we get the relation
\(y=2.5x\)
Some points which satisfy the equation is
\(y=2.5\times 1\\\Rightarrow y=2.5\)
\((1,2.5)\)
\(y=2.5\times 3\\\Rightarrow y=7.5\)
\((3,7.5)\)
\(y=2.5\times 5\\\Rightarrow y=12.5\)
\((5,12.5)\)
His goal is to earn $360 so \(y=360\)
\(360=2.5x\\\Rightarrow x=\dfrac{360}{2.5}\\\Rightarrow x=144\)
Hence, to earn $360 he must fill 144 baskets.
The algebraic relation is \(y=2.5x\).

(a) ∀x∃y(x = y²)
(b) ∀x∃y(x² = y)
(c) ∃x∀y(xy = 0)
(d) ∀x∃y(x + y = 1)
The Propositions are resulting
(a) ∀x∃y(x = y²) is False
(b) ∀x∃y(x² = y) is True.
(c) ∃x∀y(xy = 0) is True.
(d) ∀x∃y(x + y = 1) is True.
(a) ∀x∃y(x = y²)
This proposition states that for every x, there exists a y such that x is equal to y². To determine the truth value, we need to check if this statement holds true for every value of x.
If we take any positive value for x, we can find a corresponding value of y that satisfies the equation.
For example, if x = 4, then y = 2 satisfies the equation since 4 = 2². Similarly, if x = 9, then y = 3 satisfies the equation since 9 = 3².
Therefore, the proposition (a) is false.
(b) ∀x∃y(x² = y)
For any given positive or negative value of x, we can find a corresponding value of y that satisfies the equation.
For example, if x = 4, then y = 2 satisfies the equation since 4² = 2. Similarly, if x = -4, then y = -2 satisfies the equation since (-4)² = -2.
Therefore, the proposition (b) is true.
(c) ∃x∀y(xy = 0)
The equation xy = 0 can only be satisfied if x = 0, regardless of the value of y. Therefore, there exists an x (x = 0) that makes the equation true for every y.
Therefore, the proposition (c) is true.
(d) ∀x∃y(x + y = 1)
To determine the truth value, we need to check if this statement holds true for every value of x.
If we take any value of x, we can find a corresponding value of y that satisfies the equation.
For example, if x = 2, then y = -1 satisfies the equation since 2 + (-1) = 1. Similarly, if x = 0, then y = 1 satisfies the equation since 0 + 1 = 1.
Therefore, the proposition (d) is true.

Answer:I believe it's -5√41/41
Step-by-step explanation:
The value of \(cos\theta\) will be \(-0.7813\).
If the point \((-5.-4)\) were rotated around the origin, it would form a circle of radius \(r\). Also, if the point were projected to the x-axis, a right-angled triangle would be formed. Then, the value of \(cos\theta\), could be obtained by the formula
\(cos\theta=\dfrac{x}{r}\)
where
\(x=\text{the side of the triangle opposite the reference angle of }\theta\\r=\text{the radius of the circle}\)
From the point on the terminal side
\((x,y)=(-5,-4)\)
we can directly get the value of \(x\). But we need to calculate the value of \(r\).
To calculate the value of \(r\), make use of Pythagoras theorem
\(r=\sqrt{x^2+y^2}\\=\sqrt{(-5)^2+(-4)^2}\\=\sqrt{25+16}\\\approx6.4\)
We can now proceed to find the value of \(cos\theta\), since we have the values of \(x\), and \(r\). Therefore,
\(cos\theta=\dfrac{x}{r}\\\\=\dfrac{-5}{6.4}\approx-0.7813\)

If f ( x ) is a linear function, f ( − 4 ) = − 4 , and f ( 4 ) = − 1 , find an equation for f ( x ) .
Step-by-step explanation:
linear function
y = ax + b
f(-4) = -4
x = -4
y = -4
-4 = a×-4 + b
f(4) = -1
x = 4
y = -1
-1 = 4a + b
sum both equations
-5 = 0 + 2b
b = -5/2
-1 = 4a - 5/2
3/2 = 4a
a = 3/2 / 4 = 3/8
the function would be
y = 3/8 x - 5/2
