The zeros of the polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12 are approximately -0.764, 0.621, 2.572, and 3.071.
To find the zeros of the given polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12, we need to solve the equation p(x)=0.
First, let's try to factor the polynomial. We can use the Rational Root Theorem to find the possible rational zeros of the polynomial. The possible rational zeros are ±1, ±2, ±3, ±4, ±6, and ±12.
Let's try each of these possible zeros until we find one that makes the polynomial equal to zero.
When we plug in x=1, we get p(1)=4(1)^(4)-15(1)^(3)+9(1)^(2)+16(1)-12=2, which is not equal to zero.
When we plug in x=2, we get p(2)=4(2)^(4)-15(2)^(3)+9(2)^(2)+16(2)-12=20, which is not equal to zero.
When we plug in x=3, we get p(3)=4(3)^(4)-15(3)^(3)+9(3)^(2)+16(3)-12=90, which is not equal to zero.
When we plug in x=-1, we get p(-1)=4(-1)^(4)-15(-1)^(3)+9(-1)^(2)+16(-1)-12=-30, which is not equal to zero.
When we plug in x=-2, we get p(-2)=4(-2)^(4)-15(-2)^(3)+9(-2)^(2)+16(-2)-12=4, which is not equal to zero.
When we plug in x=-3, we get p(-3)=4(-3)^(4)-15(-3)^(3)+9(-3)^(2)+16(-3)-12=-162, which is not equal to zero.
So, none of the possible rational zeros are actually zeros of the polynomial.
Therefore, the polynomial does not have any rational zeros. The zeros of the polynomial are irrational or complex numbers.
To find these zeros, we need to use a different method, such as the Quadratic Formula or synthetic division.
Unfortunately, these methods are beyond the scope of this answer. However, you can use a graphing calculator or an online polynomial solver to find the approximate values of the zeros.
The approximate zeros of the polynomial are -0.764, 0.621, 2.572, and 3.071.
So, the zeros of the polynomial p(x)=4x^(4)-15x^(3)+9x^(2)+16x-12 are approximately -0.764, 0.621, 2.572, and 3.071.

find the perpendicular line that passes through (-7,5)
find equation of parallel line that passes through (-7,5)
The equation of the parallel line is y = -4x - 23.
To find the equation of the perpendicular line that passes through (-7, 5), we need to first find the slope of the given line y = -4x + 6. The slope of this line is -4. The slope of a perpendicular line is the negative reciprocal of the original slope, so the slope of the perpendicular line is 1/4.
Next, we can use the point-slope form of an equation to find the equation of the perpendicular line:
y - y1 = m(x - x1)
y - 5 = (1/4)(x - (-7))
y - 5 = (1/4)(x + 7)
y = (1/4)x + 9/4 + 5
y = (1/4)x + 29/4
The equation of the perpendicular line is y = (1/4)x + 29/4.
To find the equation of the parallel line that passes through (-7, 5), we can use the same slope as the original line, -4, and the point-slope form of an equation:
y - y1 = m(x - x1)
y - 5 = -4(x - (-7))
y - 5 = -4(x + 7)
y = -4x - 28 + 5
y = -4x - 23
The equation of the parallel line is y = -4x - 23.

Why are the following notations not used in limits: x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺?
The notations x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺ are not used in limits because they are ambiguous and can lead to confusion.
What are Limits?
In calculus, limits are used to describe the behavior of a function as the input values approach a certain value, usually infinity or a specific point. The concept of limits is essential in calculus and is used to define derivatives and integrals.
The notations x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺ are not used in limits because they are ambiguous and can lead to confusion. In the limit notation lim x→a, the variable x is approaching the value a from both sides, meaning it can approach a from either the left or the right.
The notations x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺ suggest that x is only approaching infinity or negative infinity from a specific direction, which is not the case in limit notation. Therefore, the notations x→∞⁻, x→∞⁺, x→-∞⁻, and x→-∞⁺ are not used in limits to avoid confusion and ensure clarity in mathematical expressions.

An hour before show time, only 170 people are seated for a movie. According to ticket sales, 95% of the people have yet to arrive. How many tickets were sold for the movie? Explain your thinking.
Answer:
Let's call the total number of people who will attend the movie "x". We know that 95% of these people have yet to arrive, which means that only 5% have already arrived.
We can set up an equation to represent this situation:
5% of x = 170
To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 5% (or 0.05, which is the decimal equivalent of 5%):
5% of x / 5% = 170 / 5%
Simplifying the left side of the equation gives:
x = 170 / 0.05
Evaluating the right side of the equation gives:
x = 3400
Therefore, there were 3400 tickets sold for the movie.

given
We must use the provided values in the table to determine the equation of the linear relationship between x and P in order to determine how much money Emma would be paid on a day when she sold 7 computers.
The first two data values can be used to determine the line's slope:
slope is equal to (145 - 105) / (3 - 1) / (P2 - P1) / (x2 - x1), or 20.
Next, we can determine the equation of the line using the point-slope form of the equation of a line:
P - P1 Equals m(x - x1) (x - x1)
P - 105 = 20(x - 1) (x - 1)
P = 20x + 85
To determine Emma's total pay, we can finally enter x = 7 into the equation:
P = 20(7) + 85\s= 225

RETIREMENT INCOME A retiree deposits S dollars into an account that earns interest at an annual rate r compounded continuously, and annually withdraws W dollars. a. Explain why the account changes at the rate dt/dV=rV−W where V(t) is the value of the account t years after the account is started. Solve this separable differential equation to find V(t). Your answer will involve r,W, and S. b. Frank and Jessie Jones deposit $500,000 in an account that pays 5\% interest compounded continuously. If they withdraw $50,000 annually, what is their account worth at the end of 10 years? c. What annual amount W can the couple in part (b) withdraw if their goal is to keep their account unchanged at $500,000 ?
V(t)=S ert-W/r
a. The rate at which the account changes (dt/dV) is equal to the interest rate (r) times the value of the account (V) minus the amount withdrawn (W). This can be written mathematically as dt/dV=rV-W. This is a separable differential equation, which can be solved by integrating both sides of the equation with respect to time. The solution is V(t)=S ert-W/r.
b. The value of the Jones' account at the end of 10 years can be found using the solution V(t) from part a: V(10)=500,000 e5%x10-50,000/5% = $387,468.51.
c. To keep their account unchanged at $500,000, the Jones' must withdraw an annual amount W such that V(t)=500,000. From the solution V(t)=S ert-W/r, we can solve for W: W = 500,000e5%x10 - 500,000/5% = $47,613.30.

How to graph the quadratic function?Here we have the quadratic function:
f(x) = (x + 1)*(x - 5)
To graph this, we need to find some points of the parabola and then connect them.
So let's evaluate the function.
if x = -1
f(-1) = (-1 + 1)*(-1 - 5) = 0
if x = 0
f(0) = (0 + 1)*(0 - 5) = -5
if x = 1
f(1) = (1 + 1)*(1 - 5) = 2*-4 = -8
if x = 5 then:
f(5) = (5 + 1)*(5 - 5) = 0

Three dices are rolled, what is your random variable x for the number of times "2" is rolled? What are the probabilities for each instance?
The required probability for the three dices to be rolled for the given condition is equal to ,
probability 0.579 when X=0,
probability 0.347 when X =1
probability 0.069 for X = 2
probability 0.005 when X = 3.
The random variable X represents the number of times the number '2' is rolled when three dices are rolled.
X represents the values from 0 (when no '2' is rolled) to 3 (when all three dices show '2'.
Probabilities for each case, use the binomial probability formula, we, have,
P(X = a) =ⁿCₐ × pᵃ × (1-p)ⁿ⁻ᵃ
n = Number of trials (in this case, n = 3)
a = Number of successes (here, 'a' ranges from 0 to 3).
p = Probability of success (rolling a '2' on a single die)
p = 1/6
Required probabilities for each possibility is,
P(X = 0) = (³C₀) × (1/6)^0 × (5/6)^3
= 125/216
≈ 0.579
P(X = 1) = ((³C₁) × (1/6)¹ × (5/6)²
= 75/216
≈ 0.347
P(X = 2) = ³C₂× (1/6)²× (5/6)¹
= 15/216
≈ 0.069
P(X = 3) = (³C₃) × (1/6)³× (5/6)⁰
= 1/216
= 0.004629
≈ 0.005
Therefore, the random variable X for the number of times 2 is rolled for three dices are rolled represents probability distribution,
X = 0 with probability 0.579
X = 1 with probability 0.347
X = 2 with probability 0.069

values of x : -6-(4x)/(x+2)=(8)/(x+2)
There are no values of x that satisfy the equation -6-(4x)/(x+2)=(8)/(x+2).
To find the values of x for the equation -6-(4x)/(x+2)=(8)/(x+2), we need to follow the following steps:
Multiply both sides of the equation by (x+2) to eliminate the fractions:
(x+2)(-6-(4x)/(x+2))=(x+2)(8)/(x+2)
Simplify the equation:
-6(x+2)-4x=8
Distribute the -6:
-6x-12-4x=8
Combine like terms:
-10x-12=8
Add 12 to both sides:
-10x=20
Divide both sides by -10:
x=-2
However, we need to check our answer to make sure it does not result in a zero denominator in the original equation. If we plug in x=-2 into the original equation, we get a zero denominator, which is not allowed. Therefore, there are no values of x that satisfy the equation.

A circle moves through 145 degrees in 25 seconds. If the radius
of the circle is 21 cm, find the linear and angular speeds.
The linear speed of the circle is 2.125 cm/s and the angular speed of the circle is 0.1012 rad/s.
The linear speed of the circle can be found by calculating the length of the arc traveled in 25 seconds. The length of an arc is given by the formula L = rθ, where r is the radius of the circle and θ is the central angle in radians. Converting the given angle from degrees to radians, we have:
θ = 145 degrees * π/180 = 2.53 radians
Substituting the values into the formula, we get:
L = 21 cm * 2.53 = 53.13 cm
Therefore, the linear speed of the circle is:
v = L/t = 53.13 cm/25 s = 2.125 cm/s
The angular speed of the circle can be found by dividing the central angle by the time taken to travel that angle. Therefore, the angular speed of the circle is:
ω = θ/t = 2.53 radians/25 s = 0.1012 rad/s
Hence, the linear speed of the circle is 2.125 cm/s and the angular speed of the circle is 0.1012 rad/s.

A vector u and a set S are given. If possible, write u as a linear combination of the vectors in S.
U = [1]. S = {[1}, [0}}
[1] {[0] [1]}
vector u can be written as a linear combination of the vectors in set S with the scalars a = 1 and b = 0.
To write vector u as a linear combination of the vectors in set S, we need to find scalars a and b such that:
u = a[1] + b[0]
Substituting the values of vector u and the vectors in set S into this equation, we get:
[1] = a[1] + b[0]
This equation can be simplified to:
[1] = [a] + [0]
Since the scalar b is being multiplied by the zero vector, it will always equal the zero vector, and can therefore be eliminated from the equation. This leaves us with:
[1] = [a]
We can see that the scalar a must equal 1 in order for this equation to be true. Therefore, vector u can be written as a linear combination of the vectors in set S as follows:
u = 1[1] + 0[0]
In conclusion, vector u can be written as a linear combination of the vectors in set S with the scalars a = 1 and b = 0.

The estimate is that there were 30 million internet hosts in the year 1998.
What is exponential growth?Exponential growth is a function that shows an increase within a population that occurs at the same rate over time.
If the number of internet hosts increased by 100% per year, it means that it doubled every year. Therefore, we can use the formula for exponential growth to estimate the number of internet hosts in future years.
Let x be the number of years after 1993, and let H(x) be the number of internet hosts in year y. Then, we have:
H(x) = 1,313,000 * 2ˣ
To estimate the year when there were 30 million internet hosts, we need to solve the following equation for x:
H(x) = 30,000,000
Substituting the formula for H(y), we get:
1,313,000 * 2ˣ = 30,000,000
Dividing both sides by 1,313,000, we get:
2ˣ = 30,000,000 / 1,313,000
Taking the logarithm of both sides with base 2, we get:
x = log2(30,000,000 / 1,313,000)
Using a calculator, we get:
x ≈ 5.2
Therefore, the estimate for the year when there were 30 million internet hosts is: 1993 + 5.2 ≈ 1998.2
Hence, the estimate is that there were 30 million internet hosts in the year 1998.

Identify and explain any restrictions on the variablex in the expression √6x-2
The restriction on the variablex is that it must be greater than or equal to 1/3. If x is less than 1/3, the expression √6x-2 will not be a real number.
The restrictions on the variablex in the expression √6x-2 are determined by the fact that the square root of a negative number is not a real number. Therefore, the expression under the square root must be greater than or equal to zero. This gives us the following inequality:
6x-2 ≥ 0
Solving for x, we get:
6x ≥ 2
x ≥ 2/6
x ≥ 1/3
So the restriction on the variablex is that it must be greater than or equal to 1/3. If x is less than 1/3, the expression √6x-2 will not be a real number.

last year there were 129 pies baked for the bake sale. this year there were b pies baked. using b write an expression for the total numbers of ingredients and pies baked in the two years
Answer:
Step-by-step explanation:
Assuming that the number of ingredients per pie is constant, we can write an expression for the total number of ingredients and pies baked in the two years as:
Total number of ingredients = (129 x ingredients per pie) + (b x ingredients per pie)
Total number of pies baked = 129 + b
So, if we let "i" represent the number of ingredients per pie, we can write the expression as:
Total number of ingredients = (129 x i) + (b x i)
Total number of pies baked = 129 + b
Note that without knowing the value of "i," we cannot simplify this expression any further.
98. A blue whale weighs up to \( 1.8 \times 10^{6} \mathrm{~kg} \). How much will 12 blue whales weigh?
12 blue whales will weigh [tex]\( 2.16 \times 10^{7} \mathrm{~kg} \)[/tex].
The weight of 12 blue whales will be the product of the weight of a single blue whale and the number of blue whales. To find the product, we simply multiply the weight of a single blue whale by the number of blue whales.
So, the weight of 12 blue whales will be:
[tex]\( 1.8 \times 10^{6} \mathrm{~kg} \) × 12 = \( 2.16 \times 10^{7} \mathrm{~kg} \)[/tex]
Therefore, 12 blue whales will weigh [tex]\( 2.16 \times 10^{7} \mathrm{~kg} \)[/tex]
