Find a polynomial function of lowest degree with rational coefficients that has the given numbers as some of its zeros. 1+i, 1 The polynomial function in expanded form is f(x) =
The polynomial function in expanded form is f(x) = x² - 3x² + 4x - 2.
A polynomial function with rational coefficients that has the given numbers as zeros, considering their conjugates . Since 1+i is a zero, its conjugate 1-i must also be a zero.
Using the zero-product property, that if a polynomial has a zero at a given number, then the polynomial must have a factor of (x - zero). Therefore, the polynomial function with the given zeros can be written as:
f(x) = (x - (1+i))(x - (1-i))(x - 1)
Expanding this expression,
f(x) = ((x - 1) - i)((x - 1) + i)(x - 1)
= ((x - 1)² - i²)(x - 1)
= ((x - 1)² + 1)(x - 1)
= (x² - 2x + 1 + 1)(x - 1)
= (x² - 2x + 2)(x - 1)
= x² - 2x² + 2x - x² + 2x - 2
= x² - 3x²+ 4x - 2

cindy and candy are task to clean their house cindy and candy can finish cleaning the house in 2hrs if it takes cindy working alone 3hrs longer than it takes candy working alone how many hours will each finish working
Answer:
The time it takes Candy working alone to finish cleaning the house is 3 hours
The time it takes Cindy working alone to finish cleaning the house is 6 hours
Step-by-step explanation:
The given parameters are;
The time it takes Cindy and Candy to finish cleaning the house = 2 hrs
The time it takes Cindy working alone to finish cleaning the house = 3 hrs + The time it takes Candy working alone to finish cleaning the house
Let x represent the time in hours, it takes Candy working alone to finish cleaning the house
∴ The time, in hours, it takes Cindy working alone to finish cleaning the house = 3 + x
2/x + 2/(3 + x) = 1
(2·(3 + x) + 2·x)/x·(3 + x) = 1
(2·(3 + x) + 2·x) = x·(3 + x)
6 + 2·x + 2·x = 3·x + x²
6 + 4·x = 3·x + x²
x² + 3·x - 4·x - 6 = 0
x² - x - 6 = 0
(x - 3)·(x + 2) = 0
x = 3, or x = -2
Therefore, it takes Candy, x = 3 hours working alone to finish cleaning the house, and it takes Cindy 3 + x = 3 + 3 = 6 hours working alone to finish cleaning the house.
The time it takes Candy working alone to finish cleaning the house = 3 hours
The time it takes Cindy working alone to finish cleaning the house = 6 hours

What’s the answer for LMN?
Answer:
180
Step-by-step explanation:
Suppose that R(x) is a polynomial of degree 13 whose coefficients are real numbers. also, suppose that R(x) has the following zeros. answer the following.edit: if possible please double check the answers just to be safe.
(a) Complex zeros of a polynomial come in pairs.
If a + bi is a zero of a polynomial then its conjugate a - bi is also a zero of the polynomial.
The given complex zeros of R(x) are 1 + 3i and -2i.
1 - 3i is the conjugate of 1 + 3i.
Hence, another zero of R(x) is 1 - 3i
b)
Since the polynomial R(x) is of order 13 then R(x) must have 13 zeros.
The given complex zeros of R(x) are 1 + 3i and -2i. We also know that the conjugates of 1 + 3i and -2i are zeros of R(x). Hence, R(x) has at least 4 complex roots
Hence, the maximum number of real zeros of R(x) is (13 -4).
The maximum number of real zeros of R(x) is 9
c) Let the maximum number of nonreal zeros (complex roots) be n
Complex roots come in pairs. Therefore, n must be even.
Hence, n ≤ 13 - 1 = 12
n ≤ 10
We have been given a real zero of R(x), 3 ( With the multiplicity of 4).
12 - 4 = 8
Therefore,
n ≤ 8.
Hence the maximum number of nonreal zeros of R(x) is 8

A triangle is defined by the three points: A = (7, 7) B = (2, 2), and C = (4, 8). Determine all three angles in the triangle (in radians).
The three angles in the triangle ABC are approximately 0.45 radians (A and C) and 1.37 radians (B).
To determine the three angles in the triangle ABC, we can use the law of cosines, which relates the lengths of the sides of a triangle to the cosine of the angles opposite those sides. The law of cosines states that for a triangle with sides a, b, and c, and angles A, B, and C opposite those sides:
```
a^2 = b^2 + c^2 - 2bc cos(A)
b^2 = a^2 + c^2 - 2ac cos(B)
c^2 = a^2 + b^2 - 2ab cos(C)
```
We can use these equations to solve for the three angles in the triangle ABC.
First, we need to find the lengths of the sides of the triangle. We can use the distance formula to find the lengths of the sides AB, BC, and AC:
```
AB = sqrt((7-2)^2 + (7-2)^2) = sqrt(50)
BC = sqrt((4-2)^2 + (8-2)^2) = sqrt(52)
AC = sqrt((7-4)^2 + (7-8)^2) = sqrt(10)
```
Now we can use the law of cosines to solve for the angles:
```
cos(A) = (b^2 + c^2 - a^2) / 2bc
cos(B) = (a^2 + c^2 - b^2) / 2ac
cos(C) = (a^2 + b^2 - c^2) / 2ab
```
```
cos(A) = (50 + 10 - 52) / (2 * sqrt(50) * sqrt(10)) = 0.9
cos(B) = (50 + 52 - 10) / (2 * sqrt(50) * sqrt(52)) = 0.2
cos(C) = (10 + 52 - 50) / (2 * sqrt(10) * sqrt(52)) = 0.9
```
Now we can use the inverse cosine function to find the values of A, B, and C:
```
A = acos(0.9) ≈ 0.45 radians
B = acos(0.2) ≈ 1.37 radians
C = acos(0.9) ≈ 0.45 radians
```
Therefore, the three angles in the triangle ABC are approximately 0.45 radians (A and C) and 1.37 radians (B).

Q2) For total cost: TC(q)=10−6q+q2 determine: a. the production level (q∗) that minimizes total cost. b. The amount of Total cost for the q∗, in other words TC(q∗) ? (10 pints)
The amount of total cost at q* is 1.
To determine the production level that minimizes total cost, we need to find the value of q (production level) at which the derivative of the total cost function TC(q) is equal to zero. Let's begin by finding the derivative of TC(q):
TC(q) = 10 - 6q + q^2
To find the minimum point, we differentiate TC(q) with respect to q:
d(TC(q))/dq = -6 + 2q
Setting the derivative equal to zero and solving for q:
-6 + 2q = 0
2q = 6
q = 3
So the production level q* that minimizes the total cost is 3.
To find the amount of total cost at q*, we substitute q = 3 into the total cost function TC(q):
TC(q*) = 10 - 6(3) + (3)^2
TC(q*) = 10 - 18 + 9
TC(q*) = 1
Therefore, the amount of total cost at q* is 1.

What is algebra ?
Algebra is a branch of mathematics in which letters and symbols are used to represent numbers and quantities in equations and formulas. Algebraic concepts include operations such as addition, subtraction, multiplication, and division, as well as the manipulation of equations
The maximum likelihood estimate (MLE) for p is the value that maximizes the likelihood function, which represents the probability of observing a particular sequence of red and white chips given the assumed distribution of reds and whites. In this case, we have two options for the proportion of reds, either 1/3 or 1/2. To calculate the likelihood of observing the sequence red, white, white, red, and white given p = 1/3, we calculate (1/3)(2/3)(2/3)(1/3)(2/3) = 4/243. To calculate the likelihood of observing the sequence given p = 1/2, we calculate (1/2)(1/2)(1/2)(1/2)(1/2) = 1/32. As we can see, the maximum likelihood estimate for p is 1/2, as the likelihood of observing this sequence given p = 1/2 is greater than the likelihood of observing this sequence given p = 1/3.

Simplify the expression five to the third power +3(5-3)
Answer:
Step-by-step explanation:
The expression +3(5-3) can be simplified using the order of operations (PEMDAS) as follows: first, we need to perform the exponentiation operation, which gives us 125.
Then, we need to perform the operation inside the parentheses, which gives us 6. Finally, we multiply 3 by 6, giving us 18. Therefore, the simplified expression is 125 + 18 = 143.
To further explain this solution, we use the order of operations, which is a set of rules that dictate the order in which operations must be performed when evaluating an expression. The acronym PEMDAS stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction, which represents the order of operations from left to right.
In this expression, we first need to evaluate the exponentiation operation, which is 5 to the third power. This gives us 125. Next, we need to perform the operation inside the parentheses, which is 5-3. This gives us 2. We then multiply 3 by 2, which gives us 6. Finally, we add 125 and 6, giving us 131.
It is important to follow the order of operations when simplifying an expression to ensure that we obtain the correct result. By using PEMDAS, we can systematically simplify an expression step-by-step, avoiding any potential errors and obtaining a clear and concise solution.
